Misconceived expectations: Patient reflections on the total knee replacement journey

The achievement of pre-operative expectations in patients undergoing knee arthroplasty: a cohort study evaluating unique patient goals

BACKGROUND

Total knee arthroplasty (TKA) is a common procedure employed to treat end-stage osteoarthritis. While TKA is generally believed to have acceptable outcomes, many patients report pain or functional deficits not in line with their expectation following the procedure. It has been postulated that patient's pre-operative expectations regarding post-operative treatment outcomes play a significant role in satisfaction. It is therefore important to assess if the outcomes of surgery truly align with patient's individual expectations. Thus, the purpose of this study was to determine the degree to which patient expectations of TKA are achieved and the contribution of TKA to achieving patient goals one year after surgery.

METHODS

A consecutive sample of 110 patients booked for total knee arthroplasty were asked to identify their most important goals to inform the Direct Questioning of Objectives Index (DQO Index, range 0 to 1) and identify their surgical goals and grade their expectation that a knee arthroplasty would achieve each goal on an 11-point scale. One year after surgery, the DQO Index was repeated to assess their current ability to achieve each pre-operative goal, and asked to estimate the contribution of their knee arthroplasty in achieving each goal. Mean differences between baseline and one year follow-up were calculated regarding the DQO Index and expected achievement of pre-operative goals.

RESULTS

According to the DQO Index at one year, patients improved from a poor quality of life pre-operatively (mean ± standard deviation: 0.20 ± 0.18) to moderately high quality of life (mean ± standard deviation: 0.71 ± 0.21) reflecting a large improvement in ability to achieve each goal. Although achievement improved, for each goal, the patient estimates of the extent to which the knee arthroplasty had contributed to achieving the goal was lower than their initial expectation provided pre-operatively (mean difference range: 0.6 to 1.9 on an 11-point scale).

CONCLUSION

Patients undergoing TKA have high expectations that their surgery will address their primary goals. Despite surgery largely achieving these goals (improved pain and function), the extent to which the goals were achieved was lower than patients had expected pre-operatively.

Cementless medial pivot design demonstrates equal or better outcomes compared to cementless cruciate-retaining design following total knee arthroplasty

Introduction

Traditional total knee arthroplasty (TKA) designs fail to reproduce physiologic knee kinematics, which can contribute to patient dissatisfaction. In an attempt to restore more normal knee kinematics, the medial pivot (MP) design may improve knee function and stability as well as patient satisfaction. A limited number of studies have compared postoperative outcomes of exclusively cementless Cruciate-Retaining (CR) TKAs to cementless MP TKAs. We aimed to compare: (1) 90-day, 1-year, and 2-year complications and revisions, (2) preoperative and postoperative range of motion (ROM), (3) Knee Injury and Osteoarthritis Outcome (KOOS-JR), and (4) visual analog scale (VAS) pain scores at 3-month, 6-month, 1-year, and 2-years.

Methods

A retrospective analysis was performed to identify all patients who had previously undergone a TKA at our institution and compare a cementless CR system to a cementless MP design. Categorical variables, including demographics, comorbidities, and complications utilized Chi-square tests in bivariable analysis. Continuous variables, such as age, were compared using Student's t-tests. Significance was defined as p < 0.05.

Results

Cementless CR and cementless MP cohorts showed low profiles of postoperative complications and favorable patient-reported outcome measures (PROMs). The MP cohort had lower VAS pain at 1-year (1.70 vs. 3.76, p < 0.001) and 2-years (1.43 vs. 2.60, p < 0.001) and higher ROM at 3-months (118 vs. 100, p < 0.001), 6-months (113 vs. 103, p < 0.0001), and 1-year (117 vs. 110, p = 0.02), respectively.

Conclusion

This study is the first comparison of postoperative outcomes between a cementless CR TKA and cementless MP TKA designs. Implant design and fixation type are vital components influencing patient satisfaction after TKA. Pain scores and range of motion favored the cementless MP cohort in comparison to the cementless CR cohort.

Prospective validity of a clinical prediction rule for response to non-surgical multidisciplinary management of knee osteoarthritis in tertiary care: a multisite prospective longitudinal study

OBJECTIVES

We tested a previously developed clinical prediction tool-a nomogram consisting of four patient measures (lower patient-expected benefit, lower patient-reported knee function, greater knee varus angle and severe medial knee radiological degeneration) that were related to poor response to non-surgical management of knee osteoarthritis. This study sought to prospectively evaluate the predictive validity of this nomogram to identify patients most likely to respond poorly to non-surgical management of knee osteoarthritis.

DESIGN

Multisite prospective longitudinal study.

SETTING

Advanced practice physiotherapist-led multidisciplinary service across six tertiary hospitals.

PARTICIPANTS

Participants with knee osteoarthritis deemed appropriate for trial of non-surgical management following an initial assessment from an advanced practice physiotherapist were eligible for inclusion.

INTERVENTIONS

Baseline clinical nomogram scores were collected before a trial of individualised non-surgical management commenced.

PRIMARY OUTCOME MEASURE

Clinical outcome (Global Rating of Change) was collected 6 months following commencement of non-surgical management and dichotomised to responder (a little better to a very great deal better) or poor responder (almost the same to a very great deal worse). Clinical nomogram accuracy was evaluated from receiver operating characteristics curve analysis and area under the curve, and sensitivity/specificity and positive/negative likelihood ratios were calculated.

RESULTS

A total of 242 participants enrolled. Follow-up scores were obtained from 210 participants (87% response rate). The clinical nomogram demonstrated an area under the curve of 0.70 (p<0.001), with greatest combined sensitivity 0.65 and specificity 0.64. The positive likelihood ratio was 1.81 (95% CI 1.32 to 2.36) and negative likelihood ratio 0.55 (95% CI 0.41 to 0.75).

CONCLUSIONS

The knee osteoarthritis clinical nomogram prediction tool may have capacity to identify patients at risk of poor response to non-surgical management. Further work is required to determine the implications for service delivery, feasibility and impact of implementing the nomogram in clinical practice.

Global mapping of institutional and hospital-based (Level II-IV) arthroplasty registries: a scoping review

PURPOSE

Four joint arthroplasty registries (JARs) levels exist based on the recorded data type. Level I JARs are national registries that record primary data. Hospital or institutional JARs (Level II-IV) document further data (patient-reported outcomes, demographic, radiographic). A worldwide list of Level II-IV JARs must be created to effectively assess and categorize these data.

METHODS

Our study is a systematic scoping review that followed the PRISMA guidelines and included 648 studies. Based on their publications, the study aimed to map the existing Level II-IV JARs worldwide. The secondary aim was to record their lifetime, publications' number and frequency and recognise differences with national JARs.

RESULTS

One hundred five Level II-IV JARs were identified. Forty-eight hospital-based, 45 institutional, and 12 regional JARs. Fifty JARs were found in America, 39 in Europe, nine in Asia, six in Oceania and one in Africa. They have published 485 cohorts, 91 case-series, 49 case-control, nine cross-sectional studies, eight registry protocols and six randomized trials. Most cohort studies were retrospective. Twenty-three per cent of papers studied patient-reported outcomes, 21.45% surgical complications, 13.73% postoperative clinical and 5.25% radiographic outcomes, and 11.88% were survival analyses. Forty-four JARs have published only one paper. Level I JARs primarily publish implant revision risk annual reports, while Level IV JARs collect comprehensive data to conduct retrospective cohort studies.

CONCLUSIONS

This is the first study mapping all Level II-IV JARs worldwide. Most JARs are found in Europe and America, reporting on retrospective cohorts, but only a few report on studies systematically.

Establishing a hierarchy of total knee arthroplasty patients' goals and its congruity to health professionals' perceptions: a cohort study

BACKGROUND

To formulate a hierarchy of primary goals of patients prior to total knee arthroplasty (TKA) and evaluate the agreement between patients and health professionals regarding this hierarchy of patient goals.

METHODS

The five most important goals for each of 110 consecutive patients booked for total knee arthroplasty between June and October 2019 were identified. Goals were grouped into themes and then a hierarchy formulated. This hierarchy was randomized and provided to 94 health professionals, including orthopaedic surgeons (n = 49), rheumatologists (n = 16), physiotherapists (n = 16) and general practitioners (n = 13). These health professionals ranked the provided goals based on their belief of what was most important to patients.

RESULTS

Ten overarching goals were identified, with the five most important goals to patients being improving mobility, reducing knee pain, improving daily tasks, participating in social & leisure activities and regaining knee range of motion. Health professionals ranked these goals highly similar to patients with the exceptions being that health professionals ranked quality of life near the top of the hierarchy (much higher than patients) and ranked improving mobility in the bottom half (much lower than patients). Ranking of these goals was similar between each health professional group.

CONCLUSION

Pain and mobility are the most important goals to patients, with health professionals correctly identifying these as such. However, health professionals ranked quality of life higher, and mobility lower in the hierarchy than patients. This incongruity should be considered by health professionals when educating and communicating treatment outcomes.

Accuracy of Expected Symptoms and Subsequent Quality of Life Measures Among Adults With COPD

Importance

Patients' expectations for future health guide their decisions and enable them to prepare, adapt, and cope. However, little is known about how inaccurate expectations may affect patients' illness outcomes.

Objective

To assess the association between patients' expectation inaccuracies and health-related quality of life.

Design, Setting, and Participants

This cohort study of patients with severe chronic obstructive pulmonary disease (COPD) was conducted from 2017 to 2021, which included a 24-month follow-up period. Eligible participants received outpatient primary care at pulmonary clinics of a single large US health system. Data were analyzed between 2021 and 2023.

Exposure

Expectation accuracy, measured by comparing patients' self-reported expectations of their symptom burden with their actual physical and emotional symptoms 3, 12, and 24 months in the future.

Main Outcome and Measure

Health-related quality of life, measured by the St George's Respiratory Questionnaire-COPD at 3, 12, and 24 months.

Results

A total of 207 participants were included (median age, 65.5 years [range, 42.0-86.0 years]; 120 women [58.0%]; 118 Black [57.0%], 79 White [38.2%]). The consent rate among approached patients was 80.0%. Most patients reported no or only limited discussions of future health and symptom burdens with their clinicians. Across physical and emotional symptoms and all 3 time points, patients' expectations were more optimistic than their experiences. There were no consistent patterns of measured demographic or behavioral characteristics associated with expectation accuracy. Regression models revealed that overoptimistic expectations of future burdens of dyspnea (linear regression estimate, 4.68; 95% CI, 2.68 to 6.68) and negative emotions (linear regression estimate, -3.04; 95% CI, -4.78 to 1.29) were associated with lower health-related quality of life at 3 months after adjustment for baseline health-related quality of life, forced expiratory volume over 1 second, and interval clinical events (P < .001 for both). Similar patterns were observed at 12 months (dyspnea: linear regression estimate, 2.41; 95% CI, 0.45 to 4.37) and 24 months (negative emotions: linear regression estimate, -2.39; 95% CI, -4.67 to 0.12; dyspnea: linear regression estimate, 3.21; 95% CI, 0.82 to 5.60), although there was no statistically significant association between expectation of negative emotions and quality of life at 12 months.

Conclusions and Relevance

In this cohort study of patients with COPD, we found that patients are overoptimistic in their expectations about future negative symptom burdens, and such inaccuracies were independently associated with worse well-being over time. Developing and implementing strategies to improve patients' symptom expectations may improve patient-centered outcomes.

Variation in the utilisation of physiotherapy in patients with advanced knee osteoarthritis prior to total knee arthroplasty a systematic review

INTRODUCTION

Due to demographic changes and increasing knee osteoarthritis (KOA) prevalence, the incidence of total knee arthroplasties (TKA) is constantly rising. Clinical practice guidelines for the treatment of KOA unanimously recommend non-surgical interventions such as exercise, education, and weight reduction in overweight patients. The aim of this systematic review is to determine the proportion of patients with end-stage KOA who attended physiotherapy (PT) prior to TKA.

METHODS

A systematic literature search was carried out in the medical databases MEDLINE (via Pubmed), PEDro, and EBSCO in August of 2022. Studies were included regardless of their design, if they reported the proportion of patients with a diagnosis of primary KOA, who participated in PT prior to undergoing TKA. Study quality assessment was performed by two independent authors using the Joanna Briggs Institutes Checklist for studies reporting prevalence data. Results were presented by using a narrative synthesis.

RESULTS

Eighteen studies, comprising 579,718 patients, were identified in this systematic review. PT utilisation prior to TKA ranged from 10% to 73% for patients with advanced KOA. Only two studies showed PT utilisation rates of 60% or higher. Female gender, higher income, better socioeconomic status, higher education levels, older age were associated with PT utilisation. Data for other predicting factors was conflicting.

DISCUSSION

This review shows substantial variation in the utilisation of PT in patients with end-stage KOA. This is concerning, considering the uniform recommendation from clinical practice guidelines for non-surgical treatments like exercise and education in patients with KOA, which are mostly provided by physiotherapists.

Exploring expectations of Chinese patients for total knee arthroplasty: once the medicine is taken, the symptoms vanish

BACKGROUND

Preoperative expectations of total knee arthroplasty (TKA) outcomes are important determinants of patient satisfaction. However, expectations of patients in different countries are affected by cultural background. The general goal of this study was to describe Chinese TKA patients' expectations.

METHODS

Patients scheduled for TKA were recruited in a quantitative study(n = 198). The Hospital for Special Surgery Total Knee Replacement Expectations Survey Questionnaire was used for survey TKA patients' expectations. Descriptive phenomenological design was used for the qualitative research. Semi-structured interviews were conducted with 15 TKA patients. Colaizzi's method was used for interview data analysis.

RESULTS

The mean expectation score of Chinese TKA patients was 89.17 points. The 4 highest score items were walk short distance, remove the need for walker, relieve pain and make knee or leg straight. The 2 lowest score items were employed for monetary reimbursement and sexual activity. Five main themes and 12 sub-themes emerged from the interview data, including multiple factors raised expectations, expectations of physical comfort, expect various activities back to normal, hope for a long joint lifespan, and expect a better mood.

CONCLUSIONS

Chinese TKA patients reported a relatively high level of expectations, and differences across cultures result in different expectation points than other national populations, requiring adjustment of items when using assessment tools across cultures. Strategies for expectation management should be further developed.

A synthesis of qualitative research to understand the complexity behind treatment decision-making for osteoarthritis

Objective

Osteoarthritis is the most common joint disease with treatment involving a multidisciplinary approach with pharmacological, physical therapies and surgery as options. Qualitative research can help us to understand the complexity of managing health conditions and this understanding plays a role in good clinical practice. We aimed to systematically search for, identify, and synthesise qualitative research exploring the experience of living with osteoarthritis, including decision making about joint replacement.

Methods

We comprehensively searched 4 bibliographic databases and used the methods of meta-ethnography to synthesise qualitative research findings. We screened 10 ​123 titles, 548 abstracts, and 139 full texts. We included findings from 118 reports (105 unique samples) of at least 2534 adults living with osteoarthritis around the world.

Results

We developed 7 themes: Becoming your own expert can be hard work; Living has become a careful balancing act; Medication is a double-edged sword; I have other things in my life to consider; You have to weigh up the odds of surgery; Surgery is the only effective option; and Surgery will give me a chance to live now. These findings have been drawn into a conceptual model reflecting a complex balancing act with tensions underpinning treatment decision making.

Conclusions

Osteoarthritis is framed as a world where patients become their own expert about their management and healthcare choices. Our conceptual model highlights key tensions underpinning treatment decision-making. These findings provide clinicians with insight of the complex nature of these decisions and how they can help patients through shared decision making.

Patient-Derived Framework for Quality in Hand Surgery: A Qualitative Analysis

PURPOSE

Despite the growing attention to evaluating care from the patient perspective, the most common definitions and measurements of quality are currently defined by physicians and health systems. Studies have demonstrated how a lack of patient input can lead to discrepancies between patients' and physicians' assessments of quality and, subsequently, worse patient outcomes. Although quality measures are increasingly used in hand surgery, insufficient work has examined whether these quality measures align with what matters to patients. We completed a qualitative study to assess how patients define high-quality care through the pre-, peri-, and postoperative phases of care in hand surgery.

METHODS

Based on our prior work, we created an open-ended interview guide and conducted semistructured interviews with 43 hand surgery patients at 5 tertiary-care institutions during various phases of care. We completed a thematic analysis to generate subcodes and open codes, to identify themes in high-quality care from the patient perspective.

RESULTS

Patients defined high-quality care as a process of (1) setting and meeting clear expectations; (2) achieving functional goals after surgery; and (3) feeling comfortable with and cared for by the care team. We identified the following 4 patient-centered themes that contributed to high-quality care: (1) communication between the patient and care team through all phases of care; (2) efficient and accurate diagnosis and treatment; (3) satisfactory treatment outcomes and postsurgical experience; and (4) acceptable systemic aspects of care.

CONCLUSIONS

Efforts to improve health care delivery should include areas of care that are important to patients. Our results suggest that measuring aspects of care that often go without assessments, such as communication, can maximize care quality as defined by patients.

CLINICAL RELEVANCE

The themes identified in this study can inform efforts towards patient-centered quality measure development.

"Listen to me, learn from me": a priority setting partnership for shaping interdisciplinary pain training to strengthen chronic pain care

ABSTRACT

What are the care-seeking priorities of people living with chronic pain and carers and how can these shape interdisciplinary workforce training to improve high-value pain care? Phase 1: Australian people living with chronic pain (n = 206; 90% female) and carers (n = 10; 40% female) described their pain care priorities (eDelphi, round 1). A coding framework was inductively derived from 842 pain care priorities (9 categories, 52 priorities), including validation; communication; multidisciplinary approaches; holistic care; partnerships; practitioner knowledge; self-management; medicines; and diagnosis. Phase 2: In eDelphi round 2, panellists (n = 170; valid responses) rated the importance (1 = less important; 9 = more important) of the represented framework. In parallel, cross-discipline health professionals (n = 267; 75% female) rated the importance of these same priorities. Applying the RAND-UCLA method (panel medians: 1-3: "not important," 4-6: "equivocal," or 7-9: "important"), "important" items were retained where the panel median score was >7 with panel agreement ≥70%, with 44 items (84.6%) retained. Specific workforce training targets included the following: empathic validation; effective, respectful, safe communication; and ensuring genuine partnerships in coplanning personalised care. Panellists and health professionals agreed or strongly agreed (95.7% and 95.2%, respectively) that this framework meaningfully reflected the importance in care seeking for pain. More than 74% of health professionals were fairly or extremely confident in their ability to support care priorities for 6 of 9 categories (66.7%). Phase 3: An interdisciplinary panel (n = 5) mapped an existing foundation-level workforce training program against the framework, identifying gaps and training targets. Recommendations were determined for framework adoption to genuinely shape, from a partnership perspective, Australian interdisciplinary pain training.

Can teleconsent improve patient recall of surgical risks in knee arthroplasty? A randomised controlled trial

Objectives

Informed consent plays a vital role in managing patients undergoing knee arthroplasty (KA). Unfortunately, patient recall of informed consent remains poor. Evidence has suggested that telemedicine and teleconsent can be safe, cost-effective, and well-received by patients. The primary aim of this study was to evaluate the effect of an additional preoperative teleconsent session on patient recall of surgical risks 1 month after knee arthroplasty. The secondary aim was to assess its impact on patient satisfaction.

Methods

Sixty adult patients awaiting knee arthroplasty were randomly allocated to receive an additional preoperative teleconsent consultation (intervention group) or not (control group), along with the standard informed consent on the day of surgery. Participants were contacted 1 month after surgery to assess recall of surgical risks and satisfaction with the process. Demographics and education levels were recorded for each patient.

Results

The mean recall rates were 16% and 12% in the study and control groups, respectively, with no significant difference (p = 0.42). There was a significant difference between the mean satisfaction scores in the intervention group and the control group (9.8/10 vs 9/10, p = 0.0004). Lastly, there was a significant positive correlation between the education level and the number of risks recalled in the study (p = 0.05) and control groups (p = 0.04).

Conclusion

The additional preoperative teleconsent session had no significant effect on the risk recall rate but improved patient satisfaction. Our findings suggest education level may play a role in information recall. We can advocate for the increased use of teleconsent and telemedicine in patients undergoing KA or any elective orthopaedic procedure due to its perceived positive effects on patient satisfaction rates.

A qualitative evidence synthesis using meta-ethnography to understand the experience of living with osteoarthritis pain

ABSTRACT

Osteoarthritis pain affects the lives of a large number of people around the world. Understanding other people's experience is integral to effective care and qualitative research can have an important part to pay in education and good clinical practice. We aimed to systematically search for, identify, and synthesise qualitative research exploring the experience of living with osteoarthritis in order to incorporate this knowledge into an educational resource. We comprehensively searched four bibliographic databases and used the methods of meta-ethnography to synthesise qualitative research findings. We screened 10123 titles, 548 abstracts and 139 full texts. We included findings from 118 reports (105 unique samples) of at least 2534 adults living with osteoarthritis around the world. We developed 7 themes from more than 600 findings: it is part of my life's tapestry; (yet) it is consuming me; it constrains my body and my occupations; I am becoming separated yet dependent; I accept, but I will not let it define me; (yet) this makes me feel less than the person I was. Our findings highlight the profound impact that osteoarthritis can have on people's lives and the struggle to hold onto a sense of self. They indicate that recognising these losses, and taking osteoarthritis seriously, is an integral part of effective healthcare. This finding may be transferable beyond this condition.

Patient perspectives of pain and function after knee replacement: a systematic review and meta-synthesis of qualitative studies

Introduction

Joint replacement surgery typically results in good clinical outcome, although some people experience suboptimal pain relief and functional improvement. Predicting surgical outcome is difficult.

Objectives

There is merit in better understanding patients' perspectives of pain and function to identify avoidable problems perceived to contribute to their outcome, to inform prognostic expectations, and to identify potential cointerventions to sit alongside surgery that might mitigate pain/functional problems. Here, we aimed to synthesise the available literature exploring perspectives of people with knee osteoarthritis about their pain and function following joint replacement.

Methods

Six electronic databases and 2 websites were searched. Two independent reviewers completed study inclusion, quality assessment, and data extraction. Data were iteratively synthesised using first-, second-, and third-order analyses.

Results

Twenty-eight studies were included. Four themes were identified; perceptions of pain and function were inseparable. Theme 1 addressed experiences of recovery after surgery, which often differed from expectations. Theme 2 described the challenges of the pain experience and its functional impact, including the difficulty navigating medication use in context of personal beliefs and perceived stigma. Theme 3 articulated the toll of ongoing problems spanning pain-function-mood, necessitating the need to "endure." Theme 4 encompassed the importance of clinical/social interactions on mood and pain, with reports of concerns dismissed and practical support missing.

Conclusions

Together, these findings show that numerous individual considerations beyond the technical aspects of surgery influence experiences of pain and function. A tailored approach addressing these considerations from the patient perspective could provide a basis for improved success of knee replacement surgery.

Cohort profile: the St Vincent's Melbourne Arthroplasty Outcomes (SMART) Registry, a pragmatic prospective database defining outcomes in total hip and knee replacement patients

PURPOSE

The St Vincent's Melbourne Arthroplasty Outcomes (SMART) Registry is an institutional clinical registry housed at a tertiary referral hospital in Australia. The SMART Registry is a pragmatic prospective database, which was established to capture a broad range of longitudinal clinical and patient-reported outcome data to facilitate collaborative research that will improve policy and practice relevant to arthroplasty surgery for people with advanced arthritis of the hip or knee. The purpose of this cohort profile paper is to describe the rationale for the SMART Registry's creation, its methods, baseline data and future plans for the Registry. A full compilation of the data is provided as a reference point for future collaborators.

PARTICIPANTS

The SMART Registry cohort comprises over 13 000 consecutive arthroplasty procedures in more than 10 000 patients who underwent their procedure at St Vincent's Hospital Melbourne, since January 1998. Participant recruitment, data collection and follow-up is ongoing and currently includes up to 20 years follow-up data.

FINDINGS TO DATE

SMART Registry data are used for clinical audit and feedback, as well as for a broad range of research including epidemiological studies, predictive statistical modelling and health economic evaluations. At the time of writing, there were 46 publications from SMART Registry data, with contributions from more than 67 coauthors.

FUTURE PLANS

With the recent linking of the SMART Registry with Medicare Benefits Schedule and Pharmaceutical Benefits Scheme data through the Australian Institute of Health and Welfare, research into prescribing patterns and health system utilisation is currently underway. The SMART Registry is also being updated with the Clavien-Dindo classification of surgical complications.
