Unfulfilled Expectations After Total Hip and Knee Arthroplasty Surgery: There Is a Need for Better Preoperative Patient Information and Education

The Neuromusculoskeletal Modeling Pipeline: MATLAB-based Model Personalization and Treatment Optimization Functionality for OpenSim

Neuromusculoskeletal injuries including osteoarthritis, stroke, spinal cord injury, and traumatic brain injury affect roughly 19% of the U.S. adult population. Standardized interventions have produced suboptimal functional outcomes due to the unique treatment needs of each patient. Strides have been made to utilize computational models to develop personalized treatments, but researchers and clinicians have yet to cross the "valley of death" between fundamental research and clinical usefulness. This article introduces the Neuromusculoskeletal Modeling (NMSM) Pipeline, two MATLAB-based toolsets that add Model Personalization and Treatment Optimization functionality to OpenSim. The two toolsets facilitate computational design of individualized treatments for neuromusculoskeletal impairments through the use of personalized neuromusculoskeletal models and predictive simulation. The Model Personalization toolset contains four tools for personalizing 1) joint structure models, 2) muscle-tendon models, 3) neural control models, and 4) foot-ground contact models. The Treatment Optimization toolset contains three tools for predicting and optimizing a patient's functional outcome for different treatment options using a patient's personalized neuromusculoskeletal model with direct collocation optimal control methods. Support for user-defined cost functions and model modification functions facilitate simulation of a vast number of possible treatments. An NMSM Pipeline use case is presented for an individual post-stroke with impaired walking function, where the goal was to predict how the subject's neural control could be changed to improve walking speed without increasing metabolic cost. First the Model Personalization toolset was used to develop a personalized neuromusculoskeletal model of the subject starting from a generic OpenSim full-body model and experimental walking data (video motion capture, ground reaction, and electromyography) collected from the subject at his self-selected speed. Next the Treatment Optimization toolset was used with the personalized model to predict how the subject could recruit existing muscle synergies more effectively to reduce muscle activation disparities between the paretic and non-paretic legs. The software predicted that the subject could increase his walking speed by 60% without increasing his metabolic cost per unit time by modifying existing muscle synergy recruitment. This hypothetical treatment demonstrates how NMSM Pipeline tools could allow researchers working collaboratively with clinicians to develop personalized neuromusculoskeletal models of individual patients and to perform predictive simulations for the purpose of designing personalized treatments that maximize a patient's post-treatment functional outcome.

Impact of Range of Motion Trajectory on Patient-Reported Outcomes Following Total Knee Arthroplasty

BACKGROUND

Postoperative knee range of motion (ROM) is among the most frequently reported functional metrics following total knee arthroplasty (TKA). Despite the major use of ROM as a metric, minimal literature exists assessing the progression of motion postoperatively over time or its implications on patient-reported outcome measures. As such, this study aimed to: (1) determine the recovery trajectory in knee ROM during the first year following primary TKA; and (2) determine if a correlation existed between patients' ROM recovery trajectory and patient-reported outcome measure scores.

METHODS

Data were collected prospectively on all patients undergoing a unilateral primary TKA between 2017 and 2019. Standardized goniometric measurements were used to measure knee flexion and extension at five time points: preoperatively, intraoperatively, and postoperatively at two weeks, six weeks, and one year. In addition, the Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS JR) was collected preoperatively and at the 1-year postoperative visit. A total of 306 TKA procedures were performed on 269 patients, and of those patients, 63.9% (N = 172) were women and 36.1% (N = 97) were men who had a mean age of 67 years (range, 29 to 89) and a mean body mass index of 30.8 (range, 18.2 to 49.0).

RESULTS

Mean knee flexion significantly increased from 112.8 (range, 63.0 to 140.0) degrees preoperatively to 119.0 (range, 95.0 to 140.0) degrees at one year postoperatively (mean difference = 4.61, P < 0.001). More specifically, 97.4% of flexion was restored by six weeks (111.2; range, 58.0 to 132.0) postoperatively. Knee extension also significantly improved from 5.9 (range, -5.0 to 32.0) degrees to 0.9 (range, 0 to 8.0) degrees at 1-year follow-up (mean difference = 5.03, P < 0.001). A weak positive correlation existed between preoperative ROM and KOOS JR scores (r = 0.24, P < 0.01).

CONCLUSIONS

Knee flexion ROM is restored in a nonlinear trajectory following a primary TKA, with over 90% of the progress occurring within the first six weeks postoperatively. In contrast, knee extension ROM is restored in a more linear manner. At one year postoperatively, target ROM fell between preoperative and intraoperative measurements. Neither ROM nor the recovery trajectory of motion correlates with KOOS JR scores. As such, this information can be valuable when attempting to set expectations for patient recovery.

Implementation of a "People-Like-Me" Tool for Personalized Rehabilitation After Total Knee Arthroplasty: A Mixed Methods Pilot Study

RATIONALE

While there are numerous tools available to inform if and when to use total knee arthroplasty (TKA), very few tools exist to help guide the recovery period after surgery.

AIMS AND OBJECTIVES

We piloted a decision support tool that promotes a "people-like-me" (PLM) approach to rehabilitation after total knee arthroplasty (TKA). The PLM approach encourages person-centered care by "using historical outcomes data from similar (past) patients as a template of what to expect for a new patient". In this study, we evaluated how successfully the PLM tool was implemented and examined contextual factors that may have influenced its implementation.

METHODS

Two outpatient physical therapy clinics (Clinics A and B) piloted the PLM tool from September 2020 - December 2022. We gathered data related to its implementation from multiple sources including the electronic health record (EHR), the tool itself, and surveys and interviews with patients and clinicians. We used an explanatory sequential mixed methods design to analyze the data overall and separately by each clinic.

RESULTS

Overall, the clinics met most pre-specified implementation targets, but did not use the tool as frequently as intended. Both clinics identified time, technology, and scheduling barriers to using the tool, but Clinic A scored higher in nearly every implementation outcome. Clinic A's success may have been related to its clinicians' higher level of experience, more positive attitudes towards the tool, and more active approach to implementation compared to Clinic B.

CONCLUSIONS

The clinics met most of our implementation targets, but Clinic A experienced more success than Clinic B. Future efforts to implement this PLM tool should (1) engage clinicians as active participants in the implementation process, (2) explore whether incorporating treatment recommendations into the PLM tool and/or using alternative training strategies can enhance its ability to alter clinician behavior, (3) integrate the tool within the EHR to complement existing workflows and mitigate implementation barriers, and (4) include randomized controlled trials that evaluate the tool's effectiveness and scalability across diverse clinical settings.

Linking Patient-Reported Outcome Measure Scores to Adverse Event Data to Gain Insight into Overestimation of Postoperative Patient-Reported Outcome Measure Improvement After Total Hip Arthroplasty and Total Knee Arthroplasty Due to Selective Nonresponse

BACKGROUND

The purpose of the study was to gain insight into how clinically relevant improvement in patient-reported outcome measure scores after total hip arthroplasty (THA) and total knee arthroplasty (TKA) may be underestimated or overestimated, we compared patient-reported outcome measure respondents and nonrespondents on their adverse event rates and assessed whether adverse event occurrence was associated with clinically relevant patient-reported outcome measure improvement from those without adverse events.

METHODS

All primary THAs and TKAs performed in 19 Dutch hospitals between January 2017 and December 2019 were included. The hip disability and osteoarthritis outcome score-physical function short form (HOOS-PS) and knee injury and osteoarthritis outcome score-physical function short form (KOOS-PS) were used to assess the physical function after THA and TKA, respectively. Adverse events included 1-year revision, 30-day readmission, 30-day complications, and long (ie, >75th percentile) length of stay. A clinically relevant improvement was defined as at least a 10-point decrease in HOOS-PS and 9 points in KOOS-PS scores. Associations between adverse events and clinically relevant HOOS-PS and KOOS-PS improvement were assessed using binary logistic regression models adjusted for patient characteristics and clustering of patients within hospitals.

RESULTS

There were 20,338 THA and 18,082 TKA procedures included. Adverse events occurred more frequently in HOOS-PS and KOOS-PS nonrespondents than in respondents. The THA patients experiencing revision, complications, or long length of stay were less likely to experience clinically relevant HOOS-PS improvements (odds ratios of 0.11 [0.06 to 0.20], 0.44 [0.30 to 0.63], and 0.66 [0.50 to 0.88], respectively). The TKA patients experiencing revision or long length of stay were less likely to experience clinically relevant KOOS-PS improvements (odds ratios of 0.26 [0.12 to 0.55] and 0.63 [0.50 to 0.80], respectively).

CONCLUSIONS

Clinically relevant HOOS-PS and KOOS-PS improvements are likely overestimated, as nonrespondents had higher adverse event rates which were associated with lower likelihood to achieve clinically relevant HOOS-PS and KOOS-PS improvements.

A Dutch Translation of the Hospital for Special Surgery Shoulder Expectation Survey (HSS-ES) for Preoperative Assessment in Total Shoulder Arthroplasty Patients

To date, no Dutch questionnaire exists to administer preoperative patient expectations in patients scheduled to undergo a total shoulder arthroplasty. The aim of this study is to develop a Dutch translation of the Hospital for Special Surgery Expectations Survey using a standardized translation procedure, to use both in clinical practice and in scientific research. Translation is performed on the basis of a forward - backward translation. The clarity of the pre-final Dutch version is tested on 10-30 patients scheduled to undergo a total shoulder arthroplasty. The answers of the patients are studied prospectively at a single time point. All the questions of the Hospital for Special Surgery Expectation Survey are clear to more than 80% of patients, which is the norm value where it can be assumed that the question is clearly understandable. The Dutch version of the Hospital for Special Surgery Expectations Survey can be considered clear, as all questions did not give any ambiguities for 80% of the patients. This study provides a foundation needed for further research to assess the psychometric properties of the Dutch translation of the Hospital for Special Surgery Expectations Survey.

[Postoperative rehabilitation after knee arthroplasty]

BACKGROUND

Postoperative rehabilitation after knee arthroplasty plays a decisive role in restoring the function and mobility of the affected joint. However, there is still disagreement regarding the setting, structure and content of rehabilitation after knee arthroplasty, and the evidence on the individual measures is largely unclear. The aim of this article is to provide an evidence-based overview of the current status of rehabilitation after knee arthroplasty and to critically discuss the points that are still unclear. In view of the increasing prevalence of knee osteoarthritis and the rising number of knee endoprosthesis implantations, the optimization and scientific processing of postoperative rehabilitation is more important than ever in order to be able to offer scientifically sound, practice-oriented and cost-effective rehabilitation measures in the future.

MATERIAL AND METHODS

This review is based on a systematic literature search in Medline, Cochrane Library and Web of Science databases on the topic of postoperative rehabilitation after knee arthroplasty.

RESULTS

Regarding specific treatment components, duration and frequency after knee arthroplasty, the evidence is unclear. Passive therapies should only be used supportive to active interventions. Educational programmes before and after knee arthroplasty can play a crucial role in outcome and patient satisfaction. Regular strength training should always be combined with centrally oriented components, such as motor imagery, to achieve better movement visualization and central anchoring. There is still a frequent lack of scientific evidence regarding individual therapeutic measures, their intensity, frequency, duration, exercise selection and their specific implementation in rehabilitation after knee arthroplasty. In the future, digital diagnostic and training tools will become established in both inpatient and outpatient therapy, supporting the urgently needed data collection for the scientific analysis of individual therapeutic measures.

Multiple Joint Arthroplasty in Hip and Knee Osteoarthritis Patients: A National Longitudinal Cohort Study

BACKGROUND

Many patients suffer from osteoarthritis (OA) in multiple joints, possibly resulting in multiple joint arthroplasties (MJAs). Primarily, we determined the cumulative incidence (Cin) of MJA in hip and knee joints up to 10 years. Secondly, we calculated the mean time between the first and subsequent joint arthroplasty, and evaluated the different MJA trajectories. Lastly, we compared patient characteristics and outcomes (functionality and pain) after surgery between MJA patients and single hip arthroplasty or knee arthroplasty (HA and KA) patients.

METHODS

Primary index (first) HA or KA for OA were extracted from the Dutch Arthroplasty Register. The 1, 2, 5, and 10-year Cin (including competing risk death) of MJA, mean time intervals, and MJA-trajectories were calculated and stratified for primary index HA or KA. Sex, preoperative age, and body mass index were compared using ordinal logistic regression. Outcomes, measured preoperatively, 3, 6, and 12 months postoperatively (function: Hip Disability or Knee Injury and OA Outcome Score; Pain: Numerical Rating Scale), were compared using linear regression.

RESULTS

A total of 140,406 HA-patients and 140,268 KA-patients were included. One, 2, 5, and 10-year Cin for a second arthroplasty were respectively 8.9% [95% confidence interval (CI): 8.7 to 9.0], 14.3% [95% CI: 14.1 to 14.5], 24.0% [95% CI: 23.7 to 24.2], and 32.7% [95% CI: 32.2 to 33.1] after index HA, and 9.5% [95% CI: 9.4 to 9.7], 16.0% [95% CI: 15.9 to 16.2], 26.4% [95% CI: 26.1 to 26.6], and 35.8% [95% CI: 35.4 to 36.3] after index KA. The 10-year Cin for > 2 arthroplasties were small in both the index HA and KA groups. Time-intervals from first to second, third, and fourth arthroplasty were 26 [95% CI: 26.1 to 26.7], 47 [95% CI: 46.4 to 48.4], and 58 [95% CI: 55.4 to 61.1] months after index HA, and 26 [95% CI: 25.9 to 26.3], 52 [95% CI: 50.8 to 52.7], and 61 [95% CI: 58.3 to 63.4] months after index KA. There were 83% of the second arthroplasties placed in the contralateral cognate joint (ie, knee or hip). Differences in postoperative functionality and pain between MJAs and single HAs and KAs were small.

CONCLUSIONS

The 10-year Cin showed that about one-third of patients received a second arthroplasty after approximately 2 years, with the majority in the contralateral cognate joint. Few patients received > 2 arthroplasties within 10 years. Being a women, having a higher body mass index, and being younger increased the odds of MJA. Postoperative outcomes were slightly negatively affected by MJA.

Evaluating the Readability, Credibility, and Quality of Spanish-Language Online Educational Resources for Knee Arthroplasty: Implications for Patient Education and Health Disparities

INTRODUCTION

Spanish-speaking individuals may experience language-based disparities related to elective orthopaedic procedures. Because patients often seek online health information, we assessed the readability, credibility, and quality of Spanish-language educational websites for knee arthroplasty.

METHODS

We queried "Google," "Yahoo," and "Bing" using the term "reemplazo de rodilla" (knee replacement in Spanish) and extracted the top 50 websites per search engine. Websites were categorized by information source (physician/community hospital, university/academic, other) and presence of HONcode certification. Information was assessed for readability (Fernández-Huerta formula), credibility (Journal of the American Medical Association benchmark criteria), and quality (Brief DISCERN tool); scores were compared between the categories.

RESULTS

A total of 77 unique websites were included (40.3% physician/community hospital, 35.1% university/academic). The median readability score was 59.4 (10th to 12th-grade reading level); no websites achieved the recommended level of ≤6th grade. The median Journal of the American Medical Association benchmark score was 2 (interquartile range 1 to 3), with only 7.8% of websites meeting all criteria. The median Brief DISCERN score was 16 (interquartile range 12 to 20), with 50.7% meeting the threshold for good quality. University/academic websites had better readability (P = 0.02) and credibility (P = 0.002) but similar quality (P > 0.05) compared with physician/community hospital websites. In addition, HONcode-certified websites had better quality scores (P = 0.045) but similar readability and credibility (P > 0.05) compared with noncertified websites.

DISCUSSION

We identified limitations in readability, credibility, and quality of Spanish-language online educational resources for knee arthroplasty. Healthcare providers should be aware of these patient education barriers when counseling patients, and efforts should be made to support the online information needs of Spanish-speaking orthopaedic patients and mitigate language-based disparities.

Psychological Aspects of Nerve Gap Reconstruction: Addressing Patient Perspectives and Expectations

Purpose

Preoperative expectations play a major role in determining patient satisfaction after surgery. The aim of this study was to characterize patient's preoperative expectations and postoperative perceptions of nerve gap repair surgery.

Methods

We conducted a search of Embase, Scopus, and Web of Science databases for peer-reviewed articles that studied patient expectations, perceptions, and impressions of nerve gap repair in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies related to lumbar plexus radiculopathy, reimplantation, or patient satisfaction scores without patient testimony were excluded. Primary and secondary outcomes were patient's preoperative expectations and postoperative perceptions of nerve gap repair surgery, respectively.

Results

We included 11 studies evaluating a total of 462 patients. One study evaluated only patient expectations, six studies evaluated only patient perspectives, and four studies evaluated both. Patients were generally overly optimistic in their expectations of surgery. Postoperative satisfaction ranged from 82% to 86%, and 81% to 87% of patients would choose to undergo their surgery again knowing what they know now.

Conclusions

Patient expectations in nerve gap repair are optimistic, and at times unrealistic. Patient satisfaction with nerve gap repair is high and subject to influence from preoperative education and postoperative outcomes of functional and sensory recovery.

Clinical relevance

Surgeons should be aware that patient expectations of their postoperative outcomes can have substantial impacts on their perceived management and overall satisfaction. More emphasis should be placed on preoperative education and expectation management to optimize patient satisfaction.

WOMAC, Kujala Score, and Knee Injury and Osteoarthritis Outcome Score for Quality of Life Thresholds for Predicting Increased and Decreased Likelihood of Failure to Improve Quality of Life After Total Knee Replacement

Background Improvement in quality of life is the primary goal following total knee arthroplasty (TKA). Patient-reported outcome measures (PROMs) have become the standard for evaluating TKA results, capturing the patient's perspective. However, PROMs face challenges such as inconsistent presurgery data collection and ambiguity in determining clinical significance. Establishing reliable thresholds for success and failure is crucial for comparing outcomes. Purpose To determine cutoff values for the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Kujala score, and Knee Injury and Osteoarthritis Outcome Score for Quality of Life (KOOS-QL) that significantly change the likelihood of success (TIS) or failure (TIF) to improve self-reported quality of life one year after TKA compared to the baseline probability of the studied cohort. Methods A retrospective study was conducted to evaluate PROMs following conventional cruciate-retaining (CR) TKA without patellar replacement. Patients were evaluated during 2022 and 2023, with a minimum one-year follow-up. A total of 161 successful evaluations were identified, representing 81% of all CR TKA procedures without patellar replacement performed between January 2018 and June 2022 at a single university hospital. Assessments included the three dimensions of the WOMAC scale (pain, stiffness, and function), Kujala score, and KOOS-QL. The primary outcome was to determine the threshold value of each PROM that significantly reduced or increased the likelihood of "same or worse" self-perceived improvement in quality of life compared to the cohort. Logistic regression with 200 iterations was used for statistical analysis. Results The threshold for improvement success was <4 for WOMAC-Pain, <1 for WOMAC-Stiffness, <15 for WOMAC-Function, >70 for Kujala, and >62 for KOOS-QL. Meanwhile, the threshold for increased failure was >7 for WOMAC-Pain, >3 for WOMAC-Stiffness, >26 for WOMAC-Function, <55 for Kujala, and <41 for KOOS-QL. Conclusions The study successfully established significant thresholds for success and failure in improving quality of life following CR TKA without patellar replacement. The identified thresholds for WOMAC-Pain, WOMAC-Function, and Kujala scores have good-excellent discrimination and can be confidently used to estimate sample sizes and compare quality of life improvements post-TKA.

Tibial Baseplate Migration Is Not Associated with Change in Patient-Reported Outcome Measures and Clinical Scores After TKA: A Secondary Analysis of 5 Radiostereometric Analysis Studies with 10-Year Follow-up

BACKGROUND

Radiostereometric analysis (RSA) provides highly accurate data about the migration of a total knee arthroplasty (TKA) component. However, patient-reported outcome measures (PROMs) reflect the patients' perspective of their functional status, pain, and overall health after TKA. The aim of this study was to evaluate the association between tibial implant migration and change in postoperative PROMs and clinical scores, using data pooled from long-term follow-up RSA studies.

METHODS

Individual implant migration data were collected from 5 randomized RSA studies, including a total of 300 patients with 6 distinct TKA implant designs (all Stryker). Tibial implant migration (maximum total point motion [MTPM]) was evaluated with RSA at 3 months, 1 year, and 2, 5, 7, and 10 years postoperatively. The Knee Society Score (KSS)-Knee and KSS-Function and Knee Injury and Osteoarthritis Outcome Score (KOOS) subscales were collected in all studies at the same follow-up times. Linear mixed-effects models, with adjustment for TKA implant design and patient characteristics, were used to analyze the data. The 3-month follow-up visit was used as the baseline to assess the association between implant migration and PROMs across the 10-year follow-up.

RESULTS

No association between tibial implant migration and change in KSS-Knee (p = 0.384), KSS-Function (p = 0.737), KOOS-Symptoms (p = 0.398), KOOS-Pain (p = 0.699), KOOS-Activities of Daily Living (p = 0.205), KOOS-Sport and Recreation (p = 0.702), or KOOS-Quality of Life (p = 0.368) was found across the entire follow-up. Similar results were found when using the 2-year follow-up as the baseline, after which both cemented and uncemented implants are expected to have stabilized.

CONCLUSIONS

Tibial baseplate migration was not associated with postoperative worsening in PROMs or clinical scores in patients who underwent TKA. These findings suggest that implant migration, as measured with RSA, measures a different parameter (i.e., implant-bone fixation) than PROMs (i.e., patient perception) and clinical scores. Therefore, to assess the performance and safety of TKA implant designs, RSA and PROMs cannot be used interchangeably during the postoperative follow-up of patients and evaluation of the fixation of knee implants.

Knee kinematics are not different between asymmetrical and symmetrical tibial baseplates in total knee arthroplasty: A fluoroscopic analysis of step-up and lunge motions

PURPOSE

This clinical fluoroscopy study investigated knee kinematics of two different cemented fixed-bearing, posterior-stabilised (PS) total knee arthroplasty (TKA) designs: an asymmetric tibial component including an asymmetric insert designed to optimise personalised balance and fit and its precursor symmetrical design with symmetric insert.

METHODS

A consecutive series of patients (16 TKAs from each treatment group) participating in a randomised controlled trial comparing TKA migration was included. The exclusion criterion was the use of walking aids. Flat-panel fluoroscopic recordings of step-up and lunge motions were acquired 1-year postoperatively. Medial and lateral contact points (CPs) were determined to calculate CP displacement, femoral axial rotation and pivot position. Using linear mixed-effects modelling techniques, kinematics between TKA designs were compared.

RESULTS

During knee extension between 20° flexion and full extension, the CPs moved anteriorly combined with a small internal femoral rotation (a screw-home mechanism). Whereas CP movement was reversed: femoral rollback, external femoral rotation while flexing the knee between full extension and 20° knee flexion, At larger flexion angles, femoral axial rotation (FAR) occurred around a lateral pivot point both during step-up and lunge. The symmetric design had a 2.3° larger range of FAR compared to the asymmetric design during lunge (p = 0.02). All other kinematics were comparable.

CONCLUSION

Despite the differences in design, this study showed that the asymmetric and symmetric PS TKA designs had mostly comparable knee kinematics during step-up and lunge motions. It is therefore expected that the functionality of the successor TKA design is similar to that of its precursor design.

Association Between Digitally Provided Education and 90-Day Return to Sexual Activity Following Total Knee Arthroplasty: A Randomized Controlled Trial

BACKGROUND

Contemporary total knee arthroplasty patients have increased expectations of returning to predisease function, including sexual activity (SA). The purpose of this study was to determine whether patients using a digital care management platform (DCMP) were more likely to have a higher rate and frequency of return to SA.

METHODS

We conducted an exploratory analysis of a prospective, multicenter, randomized controlled trial that enrolled patients undergoing total knee arthroplasty. A total of 304 patients were randomized to a DCMP (n = 119) providing preoperative and postoperative education regarding return to SA or standard postoperative care (control group; n = 185). Return to SA, assessed via questionnaire, patient-reported outcome measures, Timed Up and Go test, single leg stance, active range of motion and need for manipulation under anesthesia were assessed at 90 days postoperatively.

RESULTS

More patients in the DCMP group returned to SA compared to control at 90 days (58.4 versus 39.6%, P = .018); however, the control group resumed SA sooner (33.1 versus 42.0 days, P = .023). Patients who returned to SA were younger (61.6 versus 65.9 year), more often men (56 versus 35%) (P < .001), higher performing on the Timed Up and Go and single leg stance tests (P < .001), and had greater active range of motion (P = .007). There were no differences in patient-reported outcome measures or need for manipulation under anesthesia between patients that returned to SA and those who did not.

CONCLUSIONS

More patients using a DCMP resumed SA at 90 days; however, patients in the control group returned to SA sooner. Those who returned to SA were younger, possessed greater physical function, and were more often men.

Three out of four working-age patients have fulfilled expectations towards paid employment six months after total hip or knee arthroplasty: a multicentre cohort study

To investigate factors associated with fulfilment of expectations towards paid employment after total hip/knee arthroplasty (THA/TKA). Cohort study including preoperatively employed patients aged 18-64 scheduled for THA/TKA. Expectations were collected preoperatively, and 6 and 12 months postoperatively with the paid employment item of the Hospital-for-Special-Surgery Expectations Surveys (back-to-normal = 1; large improvement = 2; moderate improvement = 3; slight improvement = 4; not applicable = 5). Patients scoring not applicable were excluded. Fulfilment was calculated by subtracting preoperative from postoperative scores (< 0: unfulfilled; ≥ 0: fulfilled). Multivariable logistic regression analyses were conducted separately for THA/TKA at 6 and 12 months postoperatively. Six months postoperatively, 75% of THA patients (n = 237/n = 316) and 72% of TKA patients (n = 211/n = 294) had fulfilled expectations. Older age (TKA:OR 1.08, 95% CI 1.01-1.15) and better postoperative physical functioning (THA:OR 1.10, 95% CI 1.06-1.14; TKA:OR 1.03, 95% CI 1.01-1.06) increased the likelihood of fulfilment. Physical work tasks (THA:OR 0.12, 95% CI 0.03-0.44), preoperative sick leave (TKA:OR 0.33, 95% CI 0.17-0.65), and difficulties at work (THA:OR 0.10, 95% CI 0.03-0.35; TKA:OR 0.41, 95% CI 0.17-0.98) decreased the likelihood of fulfilment. Twelve months postoperatively similar risk factors were found. Three out of four working-age THA/TKA patients had fulfilled expectations towards paid employment at 6 months postoperatively. Preoperative factors associated with fulfilment were older age, mental work tasks, no sick leave, postoperative factors were better physical functioning, and no perceived difficulties at work.

Preoperative Expectations in Hand Surgery Patients

Introduction  Studies have shown a link between patients' preoperative expectations and their postoperative satisfaction. However, limited studies exist concerning patient factors associated with higher preoperative expectations in the hand surgery population. This study analyzed preoperative expectation scores of patients undergoing hand surgery and aimed to determine associated patient characteristics. Materials and Methods  A total of 418 elective hand surgery patients aged 15 years and older enrolled in a prospectively collected orthopaedic registry from June 2015 to December 2018 were analyzed. Patients were administered preoperative questionnaires including six Patient-Reported Outcome Measurement Information System domains and other activity and pain scales. Expectation scores were measured using the six domains of the Musculoskeletal Outcomes Data Evaluation and Management System expectations questionnaire. Bivariate and multivariable analyses were conducted to identify independent predictors of higher expectations. Results  Overall, patients had high expectations (≥ 80.0) of their hand surgery. Higher mean expectation scores were seen with females, college graduates, better baseline health status, and fewer prior hand surgeries ( p  < 0.05 for all). No significant associations were found among the Common Procedural Terminology codes and expectations. Multivariable analysis confirmed that college degree ( p  = 0.023) and less pain ( p  = 0.008) were predictive of higher baseline expectations. Conclusion  In sum, more educated patients with less pain at baseline and better baseline health status have higher expectations of their hand surgery. Hand surgeons can use these results to help focus their preoperative counseling and expectation management.

Fulfilment of patients' mandatory expectations are crucial for satisfaction: a study amongst 352 patients after total knee arthroplasty (TKA)

PURPOSE

Patient satisfaction with the results of their total knee arthroplasty (TKA) is one of the primary goals of this elective procedure. Furthermore, the association between the fulfilment of patients' expectations and their satisfaction is well known. The aim of this study was to identify the key expectations of patients awaiting a TKA, evaluate their fulfilment, and compare the outcomes between very and not fully satisfied patients.

METHODS

A prospective cohort study of patients with knee OA scheduled for primary TKA was performed. Pre- and one-year postoperatively patient-reported outcome measures (PROMs) were assessed. Expectations and their fulfilment were evaluated via a questionnaire encompassing 31 expectations. Preoperatively, expectations were indicated as mandatory, desirable and not important. Postoperatively, fulfilment was rated as exceeded, fulfilled, partially or not fulfilled, and not applicable. Satisfaction with the results of TKA was measured with a numeric rating scale (NRS) of 0-10. Discrimination between not fully satisfied and very satisfied patients was set at ≥ 8, as has been proposed recently. To identify independent predictors of this discrimination, a multivariate logistic regression analysis was performed.

RESULTS

Complete data sets of 352 patients were analysed. A set of 17 key expectations was identified. Relief of knee pain was fulfilled the most, and improvement of physical function was fulfilled the least. When asked about overall fulfilled expectations, 40% of patients rated them as exceeded, 34% as fulfilled and 26% as less fulfilled than expected. Not fully satisfied patients showed significantly lower PROMs pre- and postoperatively and less fulfilled key expectations. Higher numbers of exceeded and fulfilled mandatory expectations, higher overall fulfilment and better range of motion (ROM) were significant predictors for satisfaction ≥ 8.

CONCLUSION

Patients' expectations of TKA outcomes were high with equal emphasis on knee-related and general health-related aspects. Their fulfilment was positively associated with satisfaction. Surgeons should ask patients about mandatory expectations for successful TKA and counsel them about the likelihood of their fulfilment to avoid unrealistic expectations.

Anterior knee pain and sit-up tests predicts patients' satisfaction and improvement in quality of life after anterior stabilized total knee replacement without patellar resurfacing

PURPOSE

The purpose of this study was to assess patient satisfaction and identify risk factors for dissatisfaction after anterior stabilised conventional total knee arthroplasty (TKA) without patellar resurfacing, using the Goodman score.

METHODS

We conducted a cross-sectional study using data from our institutional database from 1 January 2018 to 1 March 2021. Patients who underwent TKA with the Vanguard® Cruciate Retaining Anterior Stabilized Knee System (Zimmer Biomet, Warsaw, Indiana, USA) without patellar replacement were included. Patients with other bearing surfaces (posterior stabilised or medial congruent) or diagnosed with infection or instability were excluded. Patients' reported outcomes, body mass index (BMI), passive range of motion, the timed up-and-go test, sit-up test, and algometry were assessed. Patients were also asked if they had anterior knee pain. Satisfaction was assessed using the Goodman scale, and logistic multivariate regression was used to identify variables associated with dissatisfaction and perceived improvement in quality of life.

RESULTS

A total of 131 TKA patients were included in the study. The median satisfaction score was 100 (interquartile range [IQR], 87.5 to 100), with the 75-point threshold at the 90th percentile according to Section A of Goodman. Section B of Goodman showed that 113 TKA patients (86.26%) reported "great improvement" or "more than I ever dreamed." Multivariate logistic regression revealed that anterior knee pain (OR 5.16, 95% CI 1.24 to 21.39), the sit-up test (OR 0.63, 95% CI 0.49 to 0.81), and BMI (OR 0.84, 95% CI 0.70 to 0.99) were significantly associated with patient dissatisfaction and a worse perceived improvement in quality of life. The receiver operating characteristics curve for the models had areas under the curve of 0.83 (95% CI 0.69 to 0.97) and 0.82 (95% CI 0.70 to 0.94), respectively.

CONCLUSION

Anterior stabilised TKA without patellar resurfacing can achieve 90% satisfaction and 86% improvement in quality of life. To improve these results, it is essential to prevent and treat anterior knee pain and enhance quadriceps strength.

Patellar resurfacing and kneeling ability after total knee arthroplasty: a systematic review

BACKGROUND

Difficulty kneeling following total knee arthroplasty (TKA) remains highly prevalent, and has cultural, social, and occupational implications. With no clear evidence of superiority, whether or not to resurface the patella remains debatable. This systematic review examined whether resurfacing the patella (PR) or not (NPR) influences kneeling ability following TKA.

METHODS

This systematic review was conducted by following PRISMA guidelines. Three electronic databases were searched utilizing a search strategy developed with the aid of a department librarian. Study quality was assessed using MINROS criteria. Article screening, methodological quality assessment and data extraction were performed by two independent authors, and a third senior author was consulted if consensus was not reached.

RESULTS

A total of 459 records were identified, with eight studies included in the final analysis, and all deemed to be level III evidence. The average MINORS score was 16.5 for comparative studies and 10.5 for non-comparative studies. The total number of patients was 24,342, with a mean age of 67.6 years. Kneeling ability was predominantly measured as a patient-reported outcome measure (PROM), with two studies also including an objective assessment. Two studies demonstrated a statistically significant link between PR and kneeling, with one demonstrating improved kneeling ability with PR and the other reporting the opposite. Other potential factors associated with kneeling included gender, postoperative flexion, and body mass index (BMI). Re-operation rates were significantly higher in the NPR cohort whereas PR cohorts had higher Feller scores, patient-reported limp and patellar apprehension.

CONCLUSION

Despite its importance to patients, kneeling remains not only under-reported but also ill-defined in the literature, with no clear consensus regarding the optimum outcome assessment tool. Conflicting evidence remains as to whether PR influences kneeling ability, and to clarify the situation, large prospective randomized studies are required.

Physical activity after revision knee arthroplasty including return to sport and work: a systematic review and meta-analysis including GRADE

BACKGROUND

The number of primary knee arthroplasties (KAs) performed annually is rising, especially among active, working age patients. Consequently, revision KA is also increasingly performed. Our aim was to systematically review the extent to which patients were physically active following revision KA, and the rate and timing of return to sport and work.

METHODS

A search was conducted in the databases Medline and Embase until February 24th, 2023. Studies describing patients with revision total knee arthroplasty (rTKA) or revision unicondylar knee arthroplasty (rUKA), with outcomes regarding physical activity or return to sport (RTS) or work (RTW) were included. Quality of studies was assessed using the Newcastle-Ottawa scale, meta-analyses were performed using RevMan 5.4 and Grading of Recommendations, Assessment, Development, and Evaluations (GRADE).

RESULTS

Of the 4,314 articles screened, 22 studies were included describing 2,462 rTKA patients (no rUKA), 42% were male with a mean age of 67 years (range 24 - 95). No studies reported objective physical activity measurements. Twenty-two studies reported patient reported outcome measures (PROMs). The PROMs that were pooled on a scale from zero to ten were the UCLA Activity Score, the Tegner Activity Level Scale, the Lower-Extremity Activity Scale, Devane Activity Score, and physical activity related subscales of the Knee injury and Osteoarthritis Outcome Score. The retrospective studies of moderate quality showed a statistically significant postoperative improvement of 1.7 points (MD = 1.71, 95% CI 1.48 - 1.94 (p < 0.0001); 14 studies, n = 1,211). For the prospective moderate-quality studies, a statistically significant postoperative increase of 0.9 points was found (MD = 0.89, 95% CI 0.48 - 1.30 (p < 0.0001); 6 studies, n = 1,027). Regarding RTS, 12% of patients participated in so-called 'non-recommended' activities (i.e., hockey, soccer, football, gymnastics, jogging, singles tennis, and basketball) after rTKA (1 study, n = 206). The pooled RTW was 86% (2 studies, range 18-95%, n = 234).

CONCLUSIONS

The majority of patients self-reported an improved postoperative activity level after rTKA. Patients could maintain an active lifestyle in daily life, including sports and work. For reliable physical activity, RTS and RTW estimations, more studies are required. In terms of GRADE, the quality of evidence for the five prospective studies was rated as low.

The relation between socioeconomic status and patient symptoms before and one year after lower extremity arthroplasty

Aims

To determine whether there was a relation between socioeconomic status (SES) and patient symptoms before and one year after total knee arthroplasty (TKA), and/or total hip arthroplasty (THA) and whether a change in symptoms was clinically relevant.

Patients and methods

A secondary analysis of a prospective cohort study was conducted on SES and osteoarthritis symptoms of patients (≥45 years old) who received a primary TKA or THA between 2016 and 2018. The relation between SES and respectively pre- and postoperative and change in patient-reported outcome measures including the Oxford Knee Score (OKS), Oxford Hip Score (OHS), Western Ontario and McMaster Universities Arthritis Index (WOMAC), the visual analog scale (VAS) for pain and the EuroQol 5-Dimensions (EQ-5D) were assessed using linear mixed-effects regression models adjusted for age and sex. The following potential confounding variables were considered in the regression models: body mass index (BMI), American Society of Anesthesiologists (ASA)- classification, Charnley-classification, smoking status, and alcohol consumption.

Results

Patients with lower SES were mostly female, had a higher BMI and ASA-classification compared to patients with a higher SES. Patients with lower SES reported lower OKS (β = 3.78, P = 0.001). Patients undergoing THA reported lower scores for the OHS (β = 4.78, P = 0.001), WOMAC (β = 11.7, P = 0.001), and less pain (VAS, β = -0.91, P = 0.001). No statistically significant differences between SES groups were seen in the quality of life and health status as measured with the EQ-5D.

Conclusion

Patients with a lower socioeconomic status reported worse symptoms and showed less clinically relevant improvement at one-year follow-up.

Parental Caregiver Expectations and Satisfaction Following Hip Reconstruction and Spinal Fusion in Children With Cerebral Palsy

Children with severe (Gross Motor Function Classification System [GMFCS] IV-V) cerebral palsy (CP) exhibit profound physical and developmental impairments and require assistance for all activities of daily living. No curative treatments exist although surgical procedures to correct underlying hip and spine deformities can improve their quality of life. Despite the efficacy of these surgeries, little is known regarding parental caregivers' expectations specific to surgical outcomes and their satisfaction with surgical outcomes. The purpose was to explore parental caregiver expectations and satisfaction with hip and spine surgeries that their children with GMFCS IV-V CP underwent. Variations among preoperative expectations, changes in expectations over time, and the relationship of expectations on caregiver satisfaction were examined. A qualitative descriptive approach with conventional content analysis was utilized. Three preoperative caregiver expectation themes were identified: increasing functionality, increasing comfort, and maintaining health and averting crisis. These themes were still present at 5-year follow-up; however, more caregivers refocused their expectations from improving function to providing palliation. A clear relationship between expectations and caregiver satisfaction, however, was not identified. A deeper understanding surrounding caregiver expectation and satisfaction following surgical procedures is needed.

Disease burden of and expectations from surgery in patients prior to total knee arthroplasty: Results of the prospective FInGK study

BACKGROUND

Disease burden in patients prior to total knee arthroplasty (TKA) varies widely between studies and countries. We aimed to characterize individuals undergoing TKA and examine their expectations from the surgery, focusing on variations in disease burden.

METHODS

Consecutive patients undergoing primary TKA in a German university hospital were recruited. A questionnaire including information on disease burden, preoperative expectations from surgery, health care utilization, demography, and socioeconomics was collected one day prior to surgery and linked to data from medical records. Patients were categorized into disease burden quartiles using the Western Ontario and McMaster Universities Osteoarthritis Index' (WOMAC) total score. Subsequently, study population's characteristics and expectations from surgery were analyzed stratified by disease burden.

RESULTS

A total of 196 patients were included (41 % male; mean age: 68.2 years). The median WOMAC was 52.0 (IQR: 41.0-58.0). Patients in Q1 were more often males (Q1: 63 % vs Q4: 29 %) and had a shorter duration of complaints with the impaired knee. They were also less restricted in social participation, reported less often signs of depression, and were less often treated with physiotherapy (Q1: 27 % vs Q4: 54 %). Furthermore, expectations from surgery were highest in patients with a low disease burden.

CONCLUSION

We found large variations in disease burden with a considerable number of patients undergoing TKA whose functional capacity is still maintained and for which guideline-recommended conservative treatment options are not fully exhausted. Further research on this subgroup as well as establishing an international consensus on specific thresholds for TKA indication are needed.

Multidimensional evaluation of the pain profile as prognostic factor in individuals with hip or knee osteoarthritis receiving total joint replacement: protocol of a 2-year longitudinal prognostic cohort study

INTRODUCTION

Knee and hip osteoarthritis are two highly prevalent musculoskeletal pain conditions. Unsuccessful rates after hip/knee replacement range from 10% to 20%. Subjects with sensitisation manifestations are vulnerable to worse clinical outcomes. Most studies have analysed outcomes up to 1 year after surgery. The aim of this 2-year longitudinal study will be to evaluate sensory-related, psychological and psychophysical pain sensitisation manifestations and a potential epigenetic biomarker as prognostic clinical outcomes for the development of chronic postoperative pain after knee or hip replacement.

METHODS AND ANALYSIS

A prospective longitudinal study with a 2-year follow-up period will be conducted. The prognostic variables will include pain, function, related-disability, anxiety, depression, quality of life, sensitisation-associated symptoms, kinesiophobia, neuropathic pain and catastrophising, and expectative of the intervention will be assessed before surgery. We will also evaluate the presence of the Val158Met polymorphism as a possible epigenetic marker. Clinical outcomes including pain, related-disability and self-perceived satisfaction, sensitisation-associated symptoms and neuropathic pain will be assessed 3, 6, 12, 18 and 24 months after surgery. These variables will be used to construct three prediction models: (1) pain and function, (2) sensitisation-associated symptomatology and (3) neuropathic pain features classifying those patients in responders and non-responders. Data from knee or hip osteoarthritis will be analysed separately. Statistical analyses will be conducted with logistic regressions.

ETHICS AND DISSEMINATION

The study has been approved by the Ethics Committee of both institutions involved (Hospital Universitario Fundación Alcorcón (HUFA) 19-141 and Universidad Rey Juan Carlos (URJC) 0312201917319). Participants will sign the written informed consent before their inclusion. Study results will be disseminated through peer-reviewed publications and presentations at scientific meetings.

Patients with limited health literacy have worse preoperative function and pain control and experience prolonged hospitalizations following shoulder arthroplasty

BACKGROUND

Patients with limited health literacy (LHL) may have difficulty understanding and acting on medical information, placing them at risk for potential misuse of health services and adverse outcomes. The purposes of our study were to determine (1) the prevalence of LHL in patients undergoing inpatient shoulder arthroplasty, (2) the association of LHL with the degree of preoperative symptom intensity and magnitude of limitations, (3) and the effects of LHL on perioperative outcomes including postoperative length of stay (LOS), total inpatient costs, and inpatient opioid consumption.

METHODS

We retrospectively identified 230 patients who underwent elective inpatient reverse or anatomic shoulder arthroplasty between January 2018 and May 2021 from a prospectively maintained single-surgeon registry. The health literacy of each patient was assessed preoperatively using the validated 4-item Brief Health Literacy Screening Tool. Patients with a Brief Health Literacy Screening Tool score ≤ 17 were categorized as having LHL. The outcomes of interest were preoperative patient-reported outcome scores and range of motion, LOS, total postoperative inpatient opioid consumption, and total inpatient costs as calculated using time-driven activity-based costing methodology. Univariate analysis was performed to determine associations between LHL and patient characteristics, as well as the outcomes of interest. Multivariable linear regression modeling was used to determine the association between LHL and LOS while controlling for potentially confounding variables.

RESULTS

Overall, 58 patients (25.2%) were classified as having LHL. Prior to surgery, these patients had significantly higher rates of opioid use (P = .002), more self-reported allergies (P = .007), and worse American Shoulder and Elbow Surgeons scores (P = .001), visual analog scale pain scores (P = .020), forward elevation (P < .001), and external rotation (P = .022) but did not significantly differ in terms of any additional demographic or clinical characteristics (P > .05). Patients with LHL had a significantly longer LOS (1.84 ± 0.92 days vs. 1.57 ± 0.58 days, P = .012) but did not differ in terms of total hospitalization costs (P = .65) or total inpatient opioid consumption (P = .721). On multivariable analysis, LHL was independently predictive of a significantly longer LOS (β, 0.14; 95% confidence interval, 0.02-0.42; P = .035).

CONCLUSION

LHL is commonplace among patients undergoing elective shoulder arthroplasty and is associated with greater preoperative symptom severity and activity intolerance. Its association with longer hospitalizations suggests that health literacy is an important factor to consider for postoperative disposition planning.

Sex differences in perceived expectations of the outcome of total hip and knee arthroplasties and their fulfillment: an observational cohort study

The influence of sex on preoperative expectations and their fulfillment following total hip and knee arthroplasty (THA/TKA) remains unexplored. We investigated differences between men and women in perceived preoperative expectations on the outcome of THA/TKA and their fulfillment 1 year postoperatively. We performed a cohort study. Expectations were collected preoperatively and 1 year postoperatively using the Hospital for Special Surgery Hip/Knee Replacement Expectations Surveys (HSS-HRES/KRES; not applicable = 0, applicable: back to normal = 1, much = 2/moderate = 3/slight improvement = 4). Fulfillment of expectations was calculated by subtracting preoperative from postoperative scores (score < 0:unfulfilled; score ≥ 0:fulfilled). We included patients with “applicable” expectations. Chi-square and ordinal regression were used to compare expectations and fulfillment regarding sex. 2333 THA (62% women) and 2398 TKA (65% women) patients were included. 77% of THA and 76% of TKA patients completed the HSS-HRES/HSS-KRES both preoperatively and 1 year postoperatively. Men more often perceived items as “applicable”, with differences in 9/20 (HSS-HRES) and 9/19 (HSS-KRES) preoperative items and, respectively, 12/20 (HSS-HRES) and 10/19 (HSS-KRES) postoperative items. The largest differences (> 10%) were found in sexual activity and working ability. 16/20 (HSS-HRES) and 14/19 (HSS-KRES) items showed an increased probability of having higher preoperative expectations of ≥ 10%, in favor of men. In all items, 60% of the respondents indicated that their expectation was fulfilled. Differences were observed in 16/20 (HSS-HRES) and 6/19 (HSS-KRES) items in favor of men. Sex differences were present in expectations and fulfillment, with higher applicability of items, preoperative expectations and fulfillment in men, especially on items related to functional activities.

Analysis of Factors That Influence Patient Satisfaction After Periacetabular Osteotomy: An Asian Cohort Study

Periacetabular osteotomy (PAO) is an effective joint-preserving procedure for developmental dysplasia of the hip. However, some patients report dissatisfaction after PAO. Because patient satisfaction is increasingly used as a health care quality metric, it is important to gain a better understanding of factors associated with patient satisfaction after PAO. The goal of this study was to investigate patient satisfaction among a cohort of Asian patients undergoing PAO. This study included 227 Asian patients who had undergone PAO at our institution between 1998 and 2016. The study participants completed a questionnaire assessing patient satisfaction, reasons for dissatisfaction, and postoperative Oxford Hip Score (OHS) and University of California, Los Angeles (UCLA), activity scale score. Based on their satisfaction levels, the participants were divided into 4 subgroups, and their demographic characteristics and postoperative patient-reported outcomes were compared. Of the 227 patients, 190 expressed satisfaction that correlated with OHS-pain, OHD-activities of daily living, and UCLA activity scale scores. Primary reasons for dissatisfaction after PAO were persistent pain (24 of 49, 49%), functional limitations (14 of 49, 29%), stiffness around the hip (4 of 49, 8%), unmet expectations (4 of 49, 8%), conversion to total hip arthroplasty (2 of 49, 4%), and complications (1 of 49, 2%). Multivariate analysis showed that preoperative Kellgren-Lawrence grades 1 and 3 were the significant predictive factors for satisfaction and dissatisfaction, respectively. The potential for lower patient satisfaction associated with Kellgren-Lawrence grade 3 because of persistent pain and functional limitations postoperatively suggests that consideration of preoperative severity of osteoarthritis could enhance patient satisfaction after PAO.

Preoperative Patient Education Programs for Orthopaedic Surgery: What Do the Programs Include? How Are They Delivered? What Are the Knowledge Gaps? A Scoping Review of 46 Studies

OBJECTIVES

To (1) describe the nature and content of the current literature on preoperative education programs for patients preparing for orthopaedic surgery, (2) assess the completeness of reporting program descriptions, and (3) report gaps within the literature.

DESIGN

Scoping review.

LITERATURE SEARCH

We searched the CINAHL, Embase, PubMed, Cochrane Reviews, PsycINFO, Web of Science, and Google Scholar databases for studies that (1) addressed preoperative education in elective orthopaedic surgery or (2) provided descriptions or evaluations of a preoperative program, including the content or outcomes of the program.

STUDY SELECTION CRITERIA

Articles were included if they addressed preoperative patient education focused on an elective orthopaedic surgery and any of the (1) descriptions of an education program including any theoretical frameworks, content, or delivery, or (2) evaluations of the process of a preoperative educational program. Studies were excluded if they were treatment programs with the goal of resolving the problem occurring prior to surgery (eg, rehabilitation or pain management prior to surgery).

DATA SYNTHESIS

We used the template for intervention description and replication (TIDieR) checklist and guide to assess the completeness of reporting of the content of educational programs. Content was synthesized descriptively and by intervention mapping. The results informed of a draft operational definition of preoperative education that we refined based on expert consultation.

RESULTS

Forty-six articles were included. There was variation in study designs, target populations, and intervention content. Preoperative education was defined in 1 out of 5 studies. Thirteen studies used a platform of video-based modules to deliver their program; 3 studies implemented virtual platforms. Results from the TIDieR checklist indicated that 30% of studies tracked adherence to and fidelity of their programs. A definition and conceptual map indicated that the length of stay, functional abilities, patient knowledge, and satisfaction were expected benefits.

CONCLUSION

Poor reporting of content, rationale, and frameworks for preoperative programs in orthopedics may explain why systematic reviews have not found support for their value. Future trials must improve rigor in design and reporting. J Orthop Sports Phys Ther 2022;52(9):572-585. Epub: 9 July 2022. doi:10.2519/jospt.2022.10614.

Patients' perspectives on the benefits of feedback on patient-reported outcome measures in a web-based personalized decision report for hip and knee osteoarthritis

BACKGROUND

Applications of patient-reported outcome measures (PROMs) for individual patient management are expanding with the support of digital tools. Providing PROM-based information to patients can potentially improve care experiences and outcomes through informing and activating patients. This study explored patients' perspectives on the benefits of receiving feedback on PROMs in the context of a web-based personalized decision report to guide care for their hip or knee osteoarthritis.

METHODS

This qualitative descriptive interview study was nested in a pragmatic clinical trial of a personalized report, which includes descriptive PROM scores and predicted postoperative PROM scores. Patients completed a semi-structured interview within 6 weeks of an office visit with an orthopaedic surgeon. Only patients who reported receiving the report and reviewing it with the surgeon and/or a health educator were included. Data were iteratively analyzed using a combination of deductive and inductive coding strategies.

RESULTS

Twenty-five patients aged 49-82 years (60% female, 72% surgical treatment decision) participated and described three primary benefits of the PROM feedback within the report: 1. Gaining Information About My Health Status, including data teaching new information, confirming what was known, or providing a frame of reference; 2. Fostering Communication Between Patient and Surgeon, encompassing use of the data to set expectations, ask and answer questions, and facilitate shared understanding; and 3. Increasing My Confidence and Trust, relating to the treatment outcomes, treatment decision, and surgeon.

CONCLUSIONS

Patients identified actual and hypothetical benefits of receiving feedback on PROM scores in the context of a web-based decision report, including advantages for those who had already made a treatment decision before seeing the surgeon. Findings provide insight into patients' perspectives on how digital PROM data can promote patient-centered care. Results should be considered in the context of the homogeneous sample and complex trial. While participants perceived value in this personalized report, questions remain regarding best practices in patient-facing data presentation and engagement.

Influence of less invasive hip preservation surgery on subsequent hip arthroplasty for osteonecrosis of the femoral head

The purpose of this study was to evaluate the outcomes of total hip arthroplasty (THA) following less invasive hip-preserving procedures (LIHPs) and present a critical overview of the literature to aid in better result interpretation. The search time was from the establishment of the database to September 2021, and the outcome indicators were extracted and analyzed by Cochrane Collaboration Review Manager software (RevMan version 5.4). Finally, 10 articles were included in this meta-analysis by searching Chinese databases and English databases. Three of them were published in Chinese, and the remaining studies were published in English. LIHP was further divided into the tantalum rod implantation group and the non-tantalum rod implantation group. The results showed that prior tantalum rod implantation increased the difficulty of conversion to THA, which was reflected mainly in the longer operative time [weighted mean difference (WMD) = 24.50, 95% confidence interval (CI) = 14.09–34.91, P < 0.00001] and greater intraoperative blood loss (WMD = 114.74, 95% CI = 33.52–195.96, P = 0.006), while no significant difference was found between the non-tantalum rod implantation group and the control group. Simultaneously, easier intraoperative fracture [odds ratio (OR) = 5.88, 95% CI = 0.93–37.05, P = 0.06] and stem malalignment (OR = 4.17, 95% CI = 1.18–14.71, P = 0.03) in the LIHP group tended to be observed than in the control THA group. However, there was no significant difference in cup anteversion and inclination angle, ectopic ossification, postoperative Harris Hip Score and survivorship between the LIHP group and the control group. Although LIHP increased the difficulty of the conversion to THA, it does not detrimentally affect the clinical results of subsequent THA in the mid-term follow-up.

Outcomes as experienced by older patients after hospitalisation: satisfaction, acceptance, frustration and hope-a grounded theory study

Background

outcomes of hospitalisation are often described in quantitative terms. It is unknown how older frail patients describe their own outcomes.

Objective

to discover how older frail persons describe their own hospitalisation outcomes and the meaning of these outcomes for their daily lives.

Design

Constructivist Grounded Theory approach.

Participants

frail older people discharged from hospital.

Methods

Open interviews in the participant’s home. Transcripts were coded inductively according to the Constructivist Grounded Theory approach.

Results

Twenty-four interviews were conducted involving 20 unique participants. Although for some participants hospitalisation was just a ripple, for others, it was a turning point. It could have positive or negative impacts on outcomes, including remaining alive, disease, fatigue/condition, complaints, daily functioning, social activities and intimate relationships, hobbies, living situation and mental well-being. Few participants were completely satisfied, but for many, a discrepancy between expectation and reality existed. Some participants could accept this, others remained hopeful and some were frustrated. Factors associated with these categories were research and treatment options, (un)clarity about the situation, setting the bar too high or pushing boundaries, confidence in physicians, character traits and social factors.

Conclusions

of the persons whose outcomes did not meet their expectations, some were frustrated, others hopeful and others accepted the situation. The following interventions can help patients to accept: clear communication about options and expectations before, during and after hospitalisation; giving room for emotions; help finding social support, encouragement to engage in pleasant activities and find meaning in small things. For some patients, psychological treatment may be needed.

Are there avoidable causes of early revision total knee arthroplasty?

Introduction

Surgeons can improve their practice by understanding potentially avoidable reasons for early revision total knee arthroplasty (rTKA). The purpose of this study is to describe potentially avoidable indications for rTKA within 5 years of the index procedure.

Methods

This retrospective observational analysis utilized the rTKA database at a large, academic orthopedic specialty hospital to identify 167 consecutive rTKA from 2014 to 2019 performed within 5 years after primary TKA (pTKA). Two fellowship-trained arthroplasty surgeons reviewed the cases to classify them as potentially avoidable or unavoidable. Unavoidable indications for rTKA included infection/wound complication, arthrofibrosis, instability due to underlying collagen disease or significant weight loss, and any traumatic event leading to pTKA failure. Potentially avoidable indications included atraumatic instability, intraoperative fracture, metal allergy, and atraumatic patellar instability or maltracking. Aseptic loosening was considered avoidable if it occurred in the presence of component malpositioning or poor cementation technique.

Results

There were 112 (67.1%) unavoidable cases and 55 avoidable cases (32.9%). Of the unavoidable cases, there were 68 rTKA for infection or wound complications (60.7%), 23 for arthrofibrosis (20.5%), 6 for instability (5.4%), 6 for postoperative fracture (5.4%), 6 for aseptic loosening (5.4%), and 3 for extensor mechanism pathology following trauma (2.6%). Of the potentially avoidable rTKA, 24 were for aseptic loosening (43.7%), 23 for atraumatic instability (41.8%), 6 for atraumatic extensor mechanism pathology (10.9%), 1 for nickel allergy (1.8%), and 1 for intraoperative fracture (1.8%).

Conclusion

These findings indicate that over 30% of early rTKA are potentially avoidable. Interventions should focus on addressing potentially avoidable causes such as short-term aseptic loosening and instability to reduce the need for costly and resource-intensive rTKA.

Same-Day Outpatient Lower-Extremity Joint Replacement: A Critical Analysis Review

➢ The economics of transitioning total joint arthroplasty (TJA) to standalone ambulatory surgery centers (ASCs) should not be capitalized on at the expense of patient safety in the absence of established superior patient outcomes. ➢ Proper patient selection is essential to maximizing safety and avoiding complications resulting in readmission. ➢ Ambulatory TJA programs should focus on reducing complications frequently associated with delays in discharge. ➢ The transition from hospital-based TJA to ASC-based TJA has substantial financial implications for the hospital, payer, patient, and surgeon.

A Model for Delivery of Orthopaedic Perioperative Education via Telehealth

With orthopaedic surgery, there is a risk of poor outcomes such as pain, decreased mobility, and decreased function, particularly if patients do not receive adequate preoperative and postoperative orthopaedic education. Healthcare education delivered via telehealth can be individualized to the patient's specific situation and health literacy level and is accessible, convenient, and timely for patients and providers. The purpose of this article is to combine two models of best practice, the EDUCATE model of patient education and Bashshur's Taxonomy of Telehealth, to describe a framework for improving delivery of preoperative and postoperative orthopaedic education. This innovative model presents a patient-centered approach to orthopaedic education that can increase patient comprehension and retention and address health literacy, through consideration of three dimensions essential for effective telehealth programs: functionality, application, and technology. Applications of the model are presented.

The Effects of a Patient-Specific Integrated Education Program on Pain, Perioperative Anxiety, and Functional Recovery following Total Knee Replacement

The perioperative care of patients undergoing total knee arthroplasty (TKA) affects functional recovery and clinical outcomes. This study aims to introduce a patient-specific integrated education program (IEP) into the TKA clinical pathway and to evaluate patient outcomes between the intervention and control groups. We performed a two-site, two-arm, parallel-prospective controlled trial. The experiment group received an IEP incorporating verbal preoperative education, prehabilitation, multidisciplinary personalized rehabilitation during hospitalization, and supervised self-executed home-based exercise after discharge. The control group received regular TKA clinical care. We monitored the pain intensity, anxiety scores, and functional scores at six time points from the pre-operation interview to 3 months post-operation. The pain score was significantly decreased in the IEP group during hospitalization (p < 0.01) and before discharge (p < 0.05). The anxiety status was also improved after intervention in terms of state and trait anxiety inventory scores (p < 0.001) during hospitalization. The patient-reported (WOMAC) or physician-reported (American Knee Society Score) functional scores (p < 0.01 at most of the time points) all improved significantly under hospitalization. We found that the patient-specific IEP combining preoperative education, prehabilitation, the in-hospital group education class, and postoperative care navigation is effective in reducing postoperative pain, decreasing perioperative anxiety, and facilitating functional recovery following TKA.

Avoidance of Total Knee Replacement in a Population Health Setting: Introducing a Noninvasive Biomechanical Intervention for Patients with Knee Osteoarthritis

The observed increase in osteoarthritis (OA) of the knee as a result of an aging population and the obesity epidemic has led to a concomitant increase in the rates of total knee replacement (TKR), placing an additional financial and social burden on the ability of health care systems to control medical costs. Our study shows how a home-based, noninvasive biomechanical intervention reduced the rate of progression to surgery for a cohort of 237 patients with knee OA deemed eligible for TKR based on pre-established clinical selection criteria. Over the 24-month study period, 204 patients (86%) avoided surgery, with only 33 patients (14%, 95% confidence interval 82%-91%) progressing to a TKR with an average length of time to TKR of 324 days (ranging from 31 to 671 days). The application of this intervention provides health plans and provider networks managing patient care under financial risk arrangements an opportunity to realize significant cost savings without compromising quality of care or clinical outcomes.

"This is not negotiable. You need to do this…": A directed content analysis of decision making in rehabilitation after knee arthroplasty

PURPOSE

To understand patients' and physical therapists' perspectives related to decision making during outpatient rehabilitation after total knee arthroplasty (TKA), and to describe potential barriers and opportunities for shared decision making (SDM) in this setting.

METHODS

A qualitative study examined the beliefs, thoughts, and experiences of patients and physical therapists regarding decision making in outpatient rehabilitation after TKA. Semi-structured interviews were conducted and analysed using directed content analysis.

RESULTS

Thirty-five participants were interviewed (20 patients, 15 physical therapists). Three main themes emerged from the data: (1) there is variability among physical therapists in how patients are involved in care decisions, (2) several features of the outpatient care paradigm are not supportive of SDM, and (3) preoperative patient-clinician interactions may facilitate SDM in postoperative rehabilitation, but these interactions are not typically utilized.

CONCLUSION

Physical therapists described using decision-making strategies with varying levels of patient involvement. Both patients and physical therapists described barriers to routine use of SDM in the outpatient setting. Several actionable strategies for overcoming these barriers were identified for providers and organizations seeking to consistently use SDM in outpatient TKA rehabilitation.

Evaluation of sexual quality of life after bilateral total hip arthroplasty surgery

BACKGROUND

Patients experience limitation of hip joint movement due to coxarthrosis, such limitation may affect the quality of sexual activity in patients. We aimed at investigating the postoperative quality of sexual life and evaluating the clinical satisfaction of patients who underwent bilateral total hip arthroplasty.

HYPOTHESIS

Postoperative sexual life quality improvement in patients undergoing bilateral total hip arthroplasty increases clinical satisfaction.

METHODS

The study included patients who underwent staged bilateral total hip arthroplasty surgery between June 2016 and January 2019. Each patient was evaluated using the sexual quality of life-female (SQOL-F) or Sexual quality of life-male (SQOL-M) questionnaire containing similar questions for both genders regarding sexual satisfaction.

RESULTS

Among all the individuals, 32 were sexually active (13 females, 19 males), and seven were not sexually active (6 females, 1 male) before the surgery. Among the 29 individuals (18 females, 11 males) who thought that their sexual life was negatively affected even before the surgery, 10 (1 female, 9 males) were found not to be negatively affected. Moreover, the sexual life of 18 females was negatively affected 27.93±14.5 months (range, 12-43) before hip arthroplasty and 11 males was negatively affected 19.5±11.0 months (range, 8-31) before the surgery as well. Twenty (10 females, 10 males) individuals stated an improvement in their sexual life, 13 (6 females, 7 males) individuals stated no change. Unfortunately, 6 (3 females, 3 males) individuals stated a degradation of their sexual activity after hip arthroplasty. Patients gained more than 60 degrees of hip range of motion and experienced significant reduction in pain after hip joint movements after surgery.

DISCUSSIONS

In our study, we evaluated sexual limitations before and after total hip arthroplasty surgery and postoperative sexual quality of life. Due to the increased range of motion of patients after surgery, the proportion of sexually active individuals increased and the sexual quality of life reached a satisfactory level.

LEVEL OF EVIDENCE

New-Onset Depression After Total Knee Arthroplasty: Consideration of the At-Risk Patient

BACKGROUND

Postoperative new-onset depression (NOD) has gained recent attention as a previously unrecognized complication which may put patients at risk for poor outcomes after elective total hip arthroplasty. We aimed to investigate risk factors for the development of NOD after total knee arthroplasty (TKA) and assess its association with postoperative complications.

METHODS

This is a retrospective, population-level investigation of elective TKA patients. Patients with a preoperative diagnosis of depression were excluded from this study. Two groups were compared: patients who were diagnosed with depression within one year after TKA (NOD) and those who did not (control). The association of both preoperative patient factors and postoperative surgical and medical complications with NOD was then determined using multivariate and univariate analyses.

RESULTS

Of 196,728 unique TKA patients in our cohort, 5351 (2.72%) were diagnosed with NOD within one year of TKA. Age <54 year old, female gender, preoperative anxiety disorder, drug, alcohol, and/or tobacco use, multiple comorbidities, and opioid use before TKA were all associated with a diagnosis of NOD postoperatively (all P < .001). Postoperative NOD was associated with periprosthetic fracture (OR 2.11; 95% CI 1.29-3.52; P = .033), aseptic failure (OR 1.61; 95% CI 1.24-2.07; P = .020), prosthetic joint infection (OR 1.55, 95% CI 1.30-1.85; P < .001), stroke (OR 1.24; 95% CI 1.09-1.42; P = .006), and venous thromboembolism (OR 1.24; 95% CI 1.12-1.37; P < .001).

CONCLUSION

Post-TKA NOD is common and is associated with poor outcomes. This may aid surgeons in developing both anticipatory measures and institute preventative measures for patients at risk for developing NOD.

A high degree of knee flexion after TKA promotes the ability to perform high-flexion activities and patient satisfaction in Asian population

Background

This study investigated whether achieving a higher degree of knee flexion after TKA promoted the ability to perform high-flexion activities, as well as patient satisfaction and quality of life.

Methods

Clinical data on 912 consecutive primary TKA cases involving a single high-flexion posterior stabilized fixed-bearing prosthesis were retrospectively analyzed. Demographic and clinical data were collected, including knee flexion angle, the ability to perform high-flexion activities, and patient satisfaction and quality of life.

Results

Of the cases, 619 (68%) achieved > 130° of knee flexion after TKA (high flexion group). Knee flexion angle and clinical scores showed significant annual changes, with the maximum improvement seen at 5 years and slight deterioration observed at 10 years postoperatively. In the high flexion group, more than 50% of the patients could not kneel or squat, and 35% could not stand up from on the floor. Multivariate analysis revealed that > 130° of knee flexion, the ability to perform high-flexion activities (sitting cross-legged and standing up from the floor), male gender, and bilateral TKA were significantly associated with patient satisfaction after TKA, while the ability to perform high-flexion activities (sitting cross-legged and standing up from the floor), male gender, and bilateral TKA were significantly associated with patient quality of life after TKA.

Conclusions

High knee flexion angle (> 130°) after TKA increased the ease of high-flexion activities and patient satisfaction. The ease of high-flexion activities also increased quality of life after TKA in our Asian patients, who frequently engage in these activities in daily life.

Patient-reported outcomes after primary or revision total hip arthroplasty: A propensity score-matched Asian cohort study

BACKGROUND

Few studies have compared patient-reported outcome measures (PROMs) between primary and revision total hip arthroplasty (THA). We investigated and compared PROMs between propensity score-matched primary and revision THA in an Asian cohort.

METHODS

The Oxford Hip Score (OHS) and University of California-Los Angeles (UCLA) activity score, satisfaction score, and Short Form-12 Health Survey (SF-12) were compared between 110 primary and 110 revision THAs after propensity score matching. Multivariate analyses were performed to determine which factors, including patients' demographics, indication for revision, and pre-operative PROMs, were associated with post-operative PROMs in the revision THA cohort.

RESULTS

The revision THA cohort demonstrated significantly lower post-operative OHS, UCLA activity score, and satisfaction score (10% decrease on average) than those in the primary THA cohort (P < .05). The difference in SF-12 mental component summary measure (MCS) between the two cohorts was statistically insignificant (P = .24). In multivariate analysis for the revision THA cohort, lower post-operative UCLA activity score was significantly associated with higher BMI and lower pre-operative UCLA activity score (P < .05).

CONCLUSION

Revision THA was associated with a modest but significant decrease in physical PROMs as compared with primary THA. Pre-operative UCLA activity score significantly affected the post-operative physical outcome measures in the revision THA cohort. However, post-operative SF-12 MCS was comparable between the primary and revision THA cohorts.

Preoperative Expectations of Patients Undergoing Knee Surgery

There is limited validated data regarding the relationship between preoperative expectations and patient-reported outcomes (PROs) in patients undergoing knee surgery. The purpose of this study was to (1) assess the preoperative expectations of patients undergoing knee surgery and (2) determine the relationship between preoperative patient demographics, PROs, and preoperative patient expectations. We hypothesized that younger patients with worse function and worse general health status would have greater expectations of knee surgery. We analyzed data from 399 patients undergoing knee surgery at an urban academic medical center. We utilized the Musculoskeletal Outcomes Data Evaluation and Management System to measure preoperative expectations. Multiple legacy PRO measures were recorded, as well as the new Patient-Reported Outcomes Measurement Information Systems (PROMIS) Computer Adaptive Testing. Nonparametric statistical analyses were performed to determine significance. Overall, patients undergoing knee surgery had high expectations, with a mean of 88.0 (95% confidence interval [CI], 86.7-89.3) and median of 91.7 (95% CI, 89.2-94.3). Greater preoperative expectations of knee surgery were associated with higher income, surgically naïve knee, lower Charlson Comorbidity Index, better PROMIS Depression and Anxiety scores, greater Marx knee activity scores, and lower total body pain (p < 0.05). Preoperative expectations of patients undergoing knee surgery are associated with a history of prior knee surgery, income, general and mental health, activity, and pain. Expectations were also found to be associated with PRO measures of function and psychological well-being. These findings may have implications for patient education and shared decision-making preoperatively. The level of evidence for the study is IV.

The influence of expectation modification in knee arthroplasty on satisfaction of patients: a randomized controlled trial

AIMS

Meeting preoperative expectations is known to be of major influence on postoperative satisfaction after total knee arthroplasty (TKA). Improved management of expectation, resulting in more realistic expectations can potentially lead to higher postoperative satisfaction. The objective of this study was to assess the effect of an additional preoperative education module, addressing realistic expectations for long-term functional recovery, on postoperative satisfaction and expectation fulfilment.

METHODS

In total, 204 primary TKA patients with osteoarthritis were enrolled in this randomized controlled trial (RCT). Patients were allocated to either usual preoperative education (control group) or usual education plus an additional module on realistic expectations (intervention group). Primary outcome was being very satisfied (numerical rating scale for satisfaction ≥ 8) with the treatment result at 12 months' follow-up. Other outcomes were change in preoperative expectations and postoperative expectation fulfilment.

RESULTS

A total of 187 patients (91.7%) were available for analysis at follow-up. In the intention-to-treat analysis, 58.5% (55/94) of patients were very satisfied with the treatment result in the control group, and 69.9% (65/93) of patients in the intervention group (adjusted odds ratio (AOR) 1.72, 95% confidence interval (CI) 0.90 to 3.29). A per-protocol analysis for patients who attended the education session (92.0%, n = 172) showed that 56.9% (49/86) of patients were very satisfied in the control group and 74.4% (61/86) in the intervention group (AOR 2.44, 95% CI 1.21 to 4.91). After preoperative education, the expectation scores in the intervention group were significantly lower (mean difference -6.9 (95% CI -10.2 to -3.6)) and did not alter in the control group (mean difference 0.5 (95% CI -2.9 to 3.9)). Overall, fulfilment of expectations at 12 months was significantly higher in the intervention group (mean difference 11.4% (95% CI 2.3 to 20.5)).

CONCLUSION

Improved preoperative patient education can modify patient expectations, resulting in higher postoperative fulfilment of expectation and higher satisfaction in the group that attended the preoperative education. This is the first RCT to confirm the potential of improved expectation management on satisfaction after TKA. Cite this article: Bone Joint J 2021;103-B(4):619-626.

Articular Cartilage Injuries of the Knee: Patient Health Literacy, Expectations for Management, and Clinical Outcomes

OBJECTIVE

The purpose of this article is to review the orthopedic literature regarding patient understanding of articular cartilage disease, interpret literature reporting patient expectations for surgical management of articular cartilage injuries of the knee, and review patient-reported outcomes and patient satisfaction with management of these injuries.

DESIGN

A retrospective review of the current literature using the PubMed database (1980-current) was performed on July 15, 2017. The search terms used were "patient understanding knee cartilage," "patient satisfaction knee cartilage," "patient expectation knee cartilage," and "patient reported outcomes knee cartilage." All searches were filtered to human studies and English language only and were reviewed by 2 independent reviewers. Studies not relevant to articular cartilage injury and/or surgical management in the knee were excluded. Additional references were found by backtracing references from obtained articles.

RESULTS

The published study search results for the terms: "patient understanding knee cartilage," "patient satisfaction knee cartilage," "patient expectation knee cartilage," and "patient reported outcomes knee cartilage" displayed a total of 873 studies. Two independent reviewers screen all studies A total of 50 published studies were relevant and included.

CONCLUSION

The subjective and objective clinical outcomes reported are inconsistently obtained resulting in difficulty drawing comparisons between studies. While the relationship between preoperative patient expectations and patient-reported outcomes and patient satisfaction has yet to be well developed, authors have reported patient and injury specific variables associated with superior and inferior outcomes. In conclusion, more work is needed to correlate patient-reported outcomes and satisfaction for cartilage treatments with preoperative expectations and health literacy.

Patient expectations predict outcomes following distal radius fracture: a prospective cohort study using the TEFTOM questionnaire

INTRODUCTION

The relationship between patient expectations and clinical outcomes has recently been of increasing interest in the field of orthopaedics. The objective of this study was to evaluate the relationships between (1) patient pre-treatment expectations and post-treatment clinical outcomes, and (2) fulfillment of expectations and patient satisfaction, following distal radius fracture.

METHODS

This was a prospective multicenter cohort study conducted across three hospitals. A total of 133 patients admitted to hospital between 2016 and 2018 with a distal radius fracture were recruited. Patients were administered the Trauma Expectation Factor (TEF) at baseline to measure expectations of pain and functioning at one-year post-injury. Patients were followed up at 6 and 12 months post-injury and outcomes were measured using the Trauma Outcome Measure (TOM), Shortened Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaire, and Short-Form 12-item (SF-12) health survey. Fulfillment of expectations was measured as TEF score minus TOM score at each time point. Patient satisfaction was also measured using the Patient Satisfaction Questionnaire Short Form (PSQ-18). Multivariate regression models were created to evaluate the effect of expectations on outcomes.

RESULTS

Patient expectations correlated moderately with outcomes at 6 and 12 months post-injury. In the multivariate analysis, patient expectations were predictive of better outcomes at 6 and 12 months. Injury severity, age, mechanism of injury, and whether the injury occurred on duty also contributed significantly to one or more regression models. Patient satisfaction correlated weakly with fulfillment of expectations at 6 months, but moderately with all outcome scores. At 12 months, satisfaction did not correlate significantly with expectations fulfillment but correlated moderately to highly with all outcome scores.

CONCLUSION

Patient expectations independently predicted outcomes at 6 and 12 months post-injury. Standardized assessment and management of patient expectations may be relevant to future clinical practice and research to best quantify and optimize patient outcomes.

Predictors of met expectations two years after knee surgery

Introduction

The purpose of this study is to determine which patient factors predict two-year postoperative met expectations in a cohort of patients undergoing knee surgery. Additionally, this study aims to measure the association between met expectations and postoperative outcomes.

Methods

319 patients undergoing knee surgery at one institution were studied. Patients completed patient-reported outcome questionnaires prior to surgery and again two years postoperatively. Preoperative Expectations and postoperative Met Expectations were measured using the Musculoskeletal Outcomes and Data Evaluation Management System (MODEMS) Expectations domain.

Results

The mean Met Expectations score was significantly lower than the preoperative Expectations Score. Worse two-year Met Expectations were associated with older age, higher BMI, greater comorbidities, more previous surgeries, black race, unemployment, lower income, government insurance, Worker's Compensation, smoking, and no injury prior to surgery. Greater Met Expectations were correlated with better scores on all two-year outcome measures as well as greater improvement on most outcome measures. Race, insurance status, function, mental health, and knee pain were found to be independent predictors of Met Expectations.

Conclusion

This study identified multiple patient factors and outcome measures that were associated with Met Expectations two years after knee surgery.

The efficacy and safety of fast track surgery (FTS) in patients after hip fracture surgery: a meta-analysis

BACKGROUND

Fast track surgery (FTS) has been gradually applied in perioperative management of orthopedic surgery, but there still some research suspected that the prognosis of patients is not as expected and the cost is high, the effect of the FTS still urgently needed for support by evidence-based medicine.

METHODS

We retrieved RCTs from medical research literature databases. Risk ratios (RR), standard mean difference (SMD), and 95% confidence intervals (CI) were calculated to compare the primary and safety endpoints.

RESULTS

Overall, a total of 8886 patients were retrieved from 57 articles, of which 4448 patients (50.06%) were randomized to experimental group whereas 4438 patients (49.94%) were randomized to control group. The result showed that FTS could significantly shorten the length of stay (LOS), decrease the visual analog scale (VAS), reduce the leaving bed time and the hospitalization costs, and improve Harris hip joint function score. The incidence of complications such as respiratory system infection, urinary system infection, venous thrombus embolism (VTE), pressure sore, incision infection, constipation, and prosthesis dislocation also has been decreased significantly. Meanwhile, FTS improved patients' satisfaction apparently.

CONCLUSIONS

This meta-analysis reveals that FTS could significantly shorten the length of stay, alleviate the pain, reduce the leaving bed time and the hospitalization costs, and improve hip function. The incidence of complications also has been decreased significantly. Meanwhile, FTS has been spoken highly in patients in terms of nursing satisfaction. Its efficacy and safety were proved to be reliable.

The virtue of optimistic realism - expectation fulfillment predicts patient-rated global effectiveness of total hip arthroplasty

BACKGROUND

Emerging evidence highlights the importance of preoperative expectations in predicting patient-reported outcomes of orthopedic surgeries. To date, it is still a matter of controversy whether patient satisfaction can be maximized by promoting either optimistic or realistic outcome expectations before surgery. Adjusting overly optimistic outcome expectancies in favor of a more realistic outlook on the limitations of total hip arthroplasty could reduce the risk of disappointment and lead to greater satisfaction with surgery outcomes. Our prospective cohort study was aimed at comparing the relative predictive influence of baseline expectations, expectation fulfillment and symptomatic improvement on the global effectiveness of total hip arthroplasty.

METHODS

Ninety patients (49 female, 41 male; mean age: 63 ± 12.87 years) fulfilled inclusion criteria and completed a comprehensive preoperative assessment comprising sociodemographic, clinical, functional and psychological phenotypes. Moreover, the strengths of preoperative expectations for improvements in eight pain-related and functional domains were recorded on a 5-point Likert-scale. At 12 months after surgery, patients were asked to rate perceived improvements in each of these domains as well as the global effectiveness of the total hip replacement on a 5-point Likert-scale. To evaluate the relative impact of preoperative expectations, symptom improvement and the fulfillment of expectations on the global effectiveness of surgery, a sequential multiple regression analysis was performed.

RESULTS

Compared with the actual improvement at 12-months follow-up, prior expectations had been overly optimistic in about 28% of patients for hip pain, in about 45% for walking ability and around 60% for back pain, independence in everyday life, physical exercise, general function social interactions and mental well-being. An optimistic hip pain expectation, walking ability at baseline and the fulfillment of expectations for walking ability, general function and independence in everyday life were found to independently predict global effectiveness ratings.

CONCLUSIONS

Positive expectation about pain and the fulfillment of expectations concerning functional domains predicted higher global effectiveness ratings. In line with many authors investigating the relationship between the fulfillment of expectations and satisfaction with medical interventions, we suggest that professionals should explicitly address their patients' expectations during the preoperative education and consultation.
