Abstract
BACKGROUND Limited data are available on return to sports and patient psychometric ratings of success after patellofemoral arthroplasty (PFA) in younger patients with high expectations to return to an active lifestyle. PURPOSE/HYPOTHESIS The purpose of this article was to determine the role of PFA and its success in meeting patient expectations regarding the return to low-impact recreational sports and an active lifestyle in younger, active patients. It was hypothesized that PFA would allow younger patients to return to low-impact sports and an active lifestyle and achieve high patient psychometric ratings. STUDY DESIGN Case series; Level of evidence, 4. METHODS In this 10-year prospective study (2009-2018), robotic-assisted PFA was performed on 44 patients (32 women and 12 men; n = 51 consecutive knees), with a mean age of 37.2 years (range, 21-50 years). The follow-up rate was 98%, with a mean of 5.3 years (range, 2-9.3 years). Primary clinical outcomes were as follows: the validated Cincinnati Knee Rating System sports activity and symptom rating scales, patient psychometric ratings of the substantial clinical benefit (SCB), and the Patient Acceptable Symptom State (PASS). Secondary outcomes were the Cincinnati Knee Rating System occupational rating, visual analog pain scale, and the 12-Item Short Form Health Survey. Survivorship was defined by conversion to total knee replacement (TKR). RESULTS Before PFA, 78% of patients (35/45 knees) were symptomatic and unable to perform recreational sports, with only 20% of patients (9/45 knees) performing some low-impact sports. After PFA, 80% of patients (36/45 knees) were able to perform low-impact sports, and 7% (3/45 knees) performed jumping-pivoting sports (P < .001). The SCB scored by the patient showed 87% of knees as good, very good, or normal. On the PASS analysis, 89% of patients (95% CI, 76%-96%) were "pleased," and 93% (95% CI, 82%-99%) would undergo surgery again. There were clinically relevant improvements in symptoms of pain, swelling, and giving way (P = .0001). Preoperatively, 91% of knees had moderate to severe pain with activities of daily living, and only 11% of knees had pain at the follow-up. Five of the 50 knees (10%) underwent TKR conversion with one patient lost to follow-up. CONCLUSION PFA resulted in a high return of patients to low-impact sports with high SCB and PASS psychometric ratings. The robotic-assisted 3-dimensional preoperative planning allowed precise intraoperative trochlear implant alignment in knees with severe trochlear dysplasia. PFA is recommended as an alternative treatment in younger patients with end-stage symptomatic patellofemoral arthritis. REGISTRATION NCT02738476 (ClinicalTrials.gov identifier).

Abstract
BACKGROUND The amount of resection or the starting point of the resection on the femoral head for cam lesions in femoroacetabular impingement (FAI) is controversial. AIM The purpose of this study was to study the effect of postoperative resection depth, and resection arc ratio of cam lesion on the frequency of achieving substantial clinical benefit (SCB), patient acceptable state (PASS) in modified Harris Hip Score (mHHS) and Hip Outcome Score Activity of Daily Living (HOSADL), 2 years postoperatively. PATIENTS AND METHODS All patients who underwent first-time hip arthroscopy for FAI with a 2-year follow-up were included in this study. Patient-reported outcomes included the mHHS, HOSADL, and visual analogue scale for pain (Pain VAS). Radiological parameters such as alpha angletraditional (αT), alpha anglecartilage (αC), resection arc ratio (% alpha anglecartilage-alpha angletraditional/360°), resection depth (''D''mm) and resection depth ratio 'D%' (D/femoral head diameter %) were measured using the 45° Dunn view. RESULTS We identified 26 patients (27 hips) with 2-year follow-up. There were 10 female and 16 male patients. The mean age of the patients was 33 ± 12 years.Higher frequency of achieving SCB threshold for mHHS was related to labrum repair (73% vs. debridement '27%' p = 0.03), lower preoperative αT (64° vs. 76°, p = 0.04), lower preoperative mHHS (54 vs. 81, p < 0.001) and higher preoperative VAS scores (8 vs. 7, p = 0.02). Higher frequency of reaching PASS threshold for mHHS was associated with lower αC (82°vs. 92° p:0.02), lower RA (8% vs. 11%, p = 0.03), lower D (2.8 mm vs. 4.5 mm p:0.03), lower D% (4.7% vs. 8.4% p = 0.04) and higher postoperative mHHS (97 vs. 82 p < 0.001). CONCLUSIONS A higher frequency of achieving SCB for HOSADL was related to lower D% (5% vs. 10.5%, p = 0.04).Cam resection depth affects the frequency of achieving clinically meaningful scores and resection depth less than 6% of the femoral head diameter seems to be appropriate for optimal results. The starting point of resection on head cartilage needs to be <90° when alpha angle is used for reference.

Abstract
PURPOSE It is unclear what score thresholds on patient-reported outcomes instruments reflect an acceptable level of upper extremity (UE) function from the perspective of patients undergoing hand surgery. The purpose of this study was to calculate the patient acceptable symptom state (PASS) for the Disabilities of the Arm, Shoulder, and Hand (QuickDASH) and Patient-Reported Outcomes Measurement Information System (PROMIS) UE Computer Adaptive Test (CAT), version 2.0, in a population who underwent hand surgery. METHODS Adult patients who underwent hand surgery between February 2019 and December 2019 at a single academic tertiary institution were identified. QuickDASH and PROMIS UE CAT version 2.0 scores were collected 1 year after surgery, as were separate symptom- and function-specific anchor questions that queried the acceptability of patients' current state. Threshold values predictive of a patient reporting an acceptable symptom state (PASS[+]) were calculated for both instruments using the 75th percentile score for patients in the PASS(+) group and the Youden Index as determined by receiver operating curve (ROC) analysis. RESULTS A total of 222 patients were included. QuickDASH and PROMIS UE CAT scores differed significantly between the PASS(+) and PASS(-) groups. The 75th percentile method yielded PASS values of <16 for the QuickDASH and >43 for the PROMIS UE CAT for both anchor questions. The ROC analysis yielded PASS estimates of <15.9 to <20.5 for the QuickDASH and >38.1 to >46.2 for the PROMIS UE CAT, with ranges calculated from differing threshold values for each of the 2 anchor questions. The ROC-based estimates demonstrated high levels of model discrimination (area under the curve ≥ 0.80). CONCLUSIONS We propose PASS estimates obtained using the 75th percentile and ROC methods. CLINICAL RELEVANCE Specifically, PASS values in the range of 15.9-20.5 for the QuickDASH and 38.1-46.2 for the PROMIS UE CAT version 2.0 should be used when interpreting outcomes at a population level.

Association Between Proximal Hamstring Tear Characteristics and Achievement of Clinically Significant Outcomes After Endoscopic and Open Repair at Minimum 2-Year Follow-up. Am J Sports Med 2024; 52:390-400.

Abstract
BACKGROUND The effect of preoperative tear characteristics and the relative efficacy of open versus endoscopic surgical techniques have not been elucidated for the surgical treatment of proximal hamstring tendon injuries. PURPOSE (1) To report on achievement rates of clinically significant outcomes at a minimum 2-year follow-up for multiple patient-reported outcomes (PROs) after surgical treatment of proximal hamstring injuries, stratified according to severity of proximal hamstring injury, and (2) to compare clinical outcomes associated with endoscopic versus open surgical repair for a subset of similarly classified tears. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A single-surgeon clinical registry was queried for patients who underwent surgical repair for proximal hamstring ruptures between January 2012 and March 2021. Injuries were classified by magnetic resonance imaging as follows: grade 1, incomplete tear with the involvement of 1 or 2 tendons; grade 2, complete tear with the involvement of 3 tendons and ≤2-cm retraction; and grade 3, complete tear with the involvement of 3 tendons and >2-cm retraction. The Patient Acceptable Symptom State (PASS) for multiple PROs was calculated and compared among injury grades and between surgical techniques. RESULTS Among 75 patients with a mean follow-up of 30.5 ± 5.1 months, 20 had grade 1 tears, 24 had grade 2 tears, and 31 had grade 3 tears. Favorable 2-year postoperative PROs were demonstrated by each grade for all measured PROs. Patients with grade 3 tears were noted to have significantly lower rates of 2-year PASS achievement for the Hip Outcome Score-Activities of Daily Living (HOS-ADL) and Hip Outcome Score-Sports Specific (HOS-SS) scales (P≤ .032). Among grade 2 tears, patients treated endoscopically demonstrated significantly greater HOS-SS (endoscopic, 91.7%; open, 58.3%; P = .045) and Patient-Reported Outcomes Measurement Information System for Physical Function (endoscopic, 80.0%; open, 50.0%; P = .033) PASS achievement rates compared with those treated with the open technique. Complication rates were highest in patients with grade 3 tears (45.2%, P = .043). CONCLUSION Surgical repair of proximal hamstring tendon tears with varying extents of tendon retraction resulted in high rates of achieving PASS at the 2-year follow-up. Among complete tears with <2 cm of retraction, endoscopic repairs exhibited equal or higher rates of achieving PASS compared with open repairs across multiple PROs at 2 years postoperatively. However, patients with complete tears and retraction >2 cm achieved lower rates of PASS on the HOS-ADL and HOS-SS scales and had a higher rate of complications.

Conditional Minimal Detectable Change for the Cochlear Implant Quality of Life-35 Profile Associated With Improved Functional Abilities 12 Months After Cochlear Implantation. JAMA Otolaryngol Head Neck Surg 2023; 149:662-669.

Abstract
Importance It is essential to measure an individual patient's baseline and follow-up abilities to demonstrate changes in clinical outcomes over time. Inherent in this strategy is interpreting whether the measured change is clinically significant and beyond measurement error. Conditional minimal detectable change (cMDC) values are widely used in many disciplines but have rarely been established for outcome measures in otolaryngology or hearing research, and never in cochlear implantation. Objective To determine cMDC values for the Cochlear Implant Quality of Life-35 (CIQOL-35) Profile instrument to enhance our understanding of the initial and ongoing changes in functional abilities from cochlear implants (CIs). Design, Setting, and Participants Item response theory analyses of responses from a multi-institutional cohort of 705 CI users at a tertiary CI center were used to derive standard error (SE) values for each possible CIQOL-35 domain score. Using an iterative approach, these SE values were used to calculate cMDC values for every possible pre-CI and post-CI domain score combination. We then compared pre-CI to 12-month post-CI CIQOL-35 domains scores in an independent cohort of 65 adult CI users to determine whether the measured change exceeded error to be clinically significant. The analysis took place on December 14, 2022. Interventions The CIQOL-35 Profile instrument and cochlear implantation. Results The cMDC values were smaller for the communication domain, and global measure and cMDC values for all domains were larger at the extremes of the measurement scale. Overall, 60 CI users (92.3%) demonstrated improvement beyond cMDC at 12 months post-CI for at least 1 CIQOL-35 domain, and no patients' scores declined beyond cMDC for any domain. The percentage of CI users demonstrating improvement beyond cMDC varied by domain, with communication (53 [81.5%]) showing the largest number of CI users improving, followed by global (42 [64.6%]) and entertainment (40 [60.9%]). In general, CI users who demonstrated improvement in CIQOL-35 domains had greater improvement in speech recognition scores than patients who did not, but the strength and significance of these associations greatly varied by domain and speech material. Conclusions and Relevance This multistep cohort study found that cMDC values for the CIQOL-35 Profile provided personalized thresholds for detecting real changes in patient self-reported functional abilities over time across multiple domains, which may inform clinical decision-making. Moreover, these longitudinal results reveal the domains with more or less improvement, which may aid in patient counseling.

Abstract
Background A large number of patient reported outcome measures (PROMs) have been developed in the English language for various lower extremity orthopaedic pathologies. Twenty different PROMs were recommended for 15 specific musculoskeletal lower extremity pathologies or surgeries. However, the availability of cross-culturally adapted versions of these recommended PROMs is unknown. Purpose The purpose of this study was to identify the cross-culturally adapted versions of recommended PROMs for individuals experiencing orthopedic lower extremity pathologies or undergoing surgeries, and to identify the psychometric evidence that supports their utilization. Study design Literature Review. Methods PubMed, Embase, Medline, Cochrane, CINAHL, SPORTDisucs and Scopus were searched for cross-culturally adapted translated studies through May 2022. The search strategy included the names of the 20 recommended PROMs from previous umbrella review along with the following terms: reliability, validity, responsiveness, psychometric properties and cross-cultural adaptation. Studies that presented a non-English language version of the PROM with evidence in at least one psychometric property to support its use were included. Two authors independently evaluated the studies for inclusion and independently extracted data. Results Nineteen PROMS had cross-culturally adapted and translated language versions. The KOOS, WOMAC, ACL-RSL, FAAM, ATRS, HOOS, OHS, MOXFQ and OKS were available in over 10 different language versions. Turkish, Dutch, German, Chinese and French were the most common languages, with each language having more than 10 PROMs with psychometric properties supporting their use. The WOMAC and KOOS were both available in 10 languages and had all three psychometric properties of reliability, validity, and responsiveness supporting their use. Conclusion Nineteen of the 20 recommended instruments were available in multiple languages. The PROM most frequently cross-culturally adapted and translated were the KOOS and WOMAC. PROMs were most frequently cross-culturally adapted and translated into Turkish. International researchers and clinicians may use this information to more consistently implement PROMs with the most appropriate psychometric evidence available to support their use. Level of evidence 3a.

Abstract
Background The Patient-Reported Outcomes Measurement Information System (PROMIS) has not been fully evaluated for outcomes assessment after hip arthroscopy to correct femoroacetabular impingement syndrome (FAIS). Purpose/Hypothesis The purpose of this study was to compare the accuracy of the PROMIS Physical Function (PF) and Pain Interference (PI) subscales with the 12-Item International Hip Outcome Tool (iHOT-12) to define patients with 3 unique substantial clinical benefit (SCB) scores-patients who reported ≥80%, ≥90%, and 100% satisfaction at 1 year after hip arthroscopy for FAIS. We hypothesized that the iHOT-12 would be more accurate than the PROMIS-PF and PROMIS-PI subscales in identifying these 3 patient groups. Study Design Cohort study (diagnosis); Level of evidence, 2. Methods We reviewed the records of patients who underwent hip arthroscopy for symptomatic FAIS at 3 centers from January 2019 through June 2021 and had 1-year clinical and radiographic follow-up data. Patients completed the iHOT-12, PROMIS-PF, and PROMIS-PI on initial assessment and at 1 year (±30 days) postoperatively. Postoperative satisfaction was reported on an 11-category scale with anchors defined as "0% satisfied" and "100% satisfied." Receiver operator characteristic analysis was performed to determine the absolute SCB values for the iHOT-12 and PROMIS subscales that would most accurately identify those patients who reported ≥80%, ≥90%, and 100% satisfaction. Area under the curve (AUC) values and 95% CIs for the 3 instruments were compared. Results Included were 163 patients (111 [68%] women and 52 [32%] men), with a mean age of 26.1 years. Corresponding absolute SCB scores for patients who reported ≥80%, ≥90%, and 100% satisfaction were as follows: iHOT-12, 68.4, 72.1, 74.7; PROMIS-PF, 45, 47.7, 49.9; and PROMIS-PI, 55.9, 52.4, 51.9. The AUC ranged between 0.67 and 0.82, with overlapping 95% CIs indicating a minimal difference in accuracy between the 3 instruments. Sensitivity and specificity values ranged between 0.61 and 0.82. Conclusion The PROMIS-PF and PROMIS-PI subscales were as accurate as the iHOT-12 in defining absolute SCB scores for patients reporting ≥80%, ≥90%, and 100% satisfaction at 1-year follow-up after hip arthroscopy for FAIS.

Abstract
INTRODUCTION Rectus femoris (RF) transfer was long the gold-standard treatment for stiff knee gait (SKG), but efficacy now seems less than that of distal RF release. The aim of the present study was to compare efficacy between the two. The study hypothesis was that both significantly improve 4 knee kinematic parameters at 1 year. PATIENTS AND METHOD A meta-analysis was performed, using PRISMA criteria, on the Medline, Science Direct, Cochrane Registry, Scopus and Pascal databases. Search was conducted up to March 1, 2020 by two authors (A.J & M.T). Study methodology was assessed on MINORS index. Inclusion criteria comprised patients with SKG, treated by RF transfer or distal release. Endpoints comprised: Peak Knee Flexion in swing phase (PKFSW), Knee Range of Motion (KROM), time to Peak Knee Flexion (t-PKFGC), and Maximum Knee Extension in stance phase (MKEST). Effect size was assessed on Standard Mean Deviation (SMD). RESULTS A total of 695 studies were identified, 16 of which were included: 14 transfer, 5 release. Data were analyzed for 1,079 limbs in 768 patients. Only transfer improved PKFSW, with small effect size (SMD=0.29). The other three parameters were improved by both techniques, with moderate effect size. DISCUSSION Results showed improved knee kinematics after RF transfer, but with small or moderate effect size. The effect of distal release on PKF could not be assessed, due to publication bias. The heterogeneity of studies and low levels of evidence call for caution in interpreting the present results.

Abstract
PURPOSE Meaningful thresholds are needed to interpret patient-reported outcome measure (PROM) results. This paper introduces a new method, based on item response theory (IRT), to estimate such thresholds. The performance of the method is examined in simulated datasets and two real datasets, and compared with other methods. METHODS The IRT method involves fitting an IRT model to the PROM items and an anchor item indicating the criterion state of interest. The difficulty parameter of the anchor item represents the meaningful threshold on the latent trait. The latent threshold is then linked to the corresponding expected PROM score. We simulated 4500 item response datasets to a 10-item PROM, and an anchor item. The datasets varied with respect to the mean and standard deviation of the latent trait, and the reliability of the anchor item. The real datasets consisted of a depression scale with a clinical depression diagnosis as anchor variable and a pain scale with a patient acceptable symptom state (PASS) question as anchor variable. RESULTS The new IRT method recovered the true thresholds accurately across the simulated datasets. The other methods, except one, produced biased threshold estimates if the state prevalence was smaller or greater than 0.5. The adjusted predictive modeling method matched the new IRT method (also in the real datasets) but showed some residual bias if the prevalence was smaller than 0.3 or greater than 0.7. CONCLUSIONS The new IRT method perfectly recovers meaningful (interpretational) thresholds for multi-item questionnaires, provided that the data satisfy the assumptions for IRT analysis.

Preoperative Opioid Use Predicts Postoperative Opioid Use and Inferior Clinically Notable Outcomes After Total Shoulder Arthroplasty. J Am Acad Orthop Surg 2022; 30:e242-e251. [PMID: 34644714 DOI: 10.5435/jaaos-d-21-00319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/12/2021] [Accepted: 09/02/2021] [Indexed: 02/01/2023] Open
Abstract
INTRODUCTION Preoperative opioid use (OU) may negatively affect outcomes after total shoulder arthroplasty (TSA). This study aims to evaluate the influence of preoperative OU on achievement of midterm clinically notable outcomes (CSOs) after TSA and identify factors associated with prolonged postoperative OU and persistent pain after TSA. METHODS Using a single-institution, prospectively collected TSA registry, we retrospectively identified patients who underwent surgery between 2014 and 2019. Subjects were stratified into two cohorts: preoperative OU within 12 months of surgery and opioid naive (N-OU) patients. Minimum 1-year postoperative scores and achievement of CSOs patient-reported outcome measures (PROMs), as well as predictors of postoperative OU and persistent pain, were analyzed. RESULTS A total of 817 patients were included with 706 patients in the N-OU cohort and 111 patients in the OU cohort. Although both patients in the N-OU and OU cohorts showed statistically significant improvements at the 1-year follow-up, absolute PROM scores were less favorable in the OU cohort (all P < 0.05). Preoperative opioid users were significantly less likely to achieve minimal clinically important difference (odds ratios [ORs]: 0.47 to 2.4, all P < 0.05) and patient acceptable symptomatic state (ORs: 0.41 to 2.12, all P < 0.05) on the American Shoulder and Elbow Surgeon, Single Assessment Numeric Evaluation, Constant-Murley Shoulder Score, Visual Analogue Scale (VAS) pain, Veterans Rand 12-Item Health Survey, Short-Form 12-Item Health Survey, and Veterans Rand 6D and substantial clinical benefit (OR: 0.50 to 0.56, P < 0.05) on the American Shoulder and Elbow Surgeon and Single Assessment Numeric Evaluation. Preoperative OU significantly predicted increased OU at 6 months (OR: 7.11, P = 0.009) and 1-year follow-up (OR: 40.23, P < 0.001) and persistent pain at 1 year (OR: 2.37, P = 0.001). CONCLUSION Preoperative OU markedly correlated with worse PROMs at 1 year postoperatively. Although preoperative opioid users demonstrate improvement in functional-related and health-related quality-of-life PROMs after TSA, they are markedly less likely to achieve CSOs and were more likely to report persistent pain and continued OU at 6-month and 1-year follow-ups. Opioid users undergoing TSA should be counseled regarding their expected outcomes, and preventive measures should aim to limit prolonged OU/abuse after surgery.

Abstract
A shift toward a value-driven health-care model has made prospective collection of patient-reported outcome measures (PROMs) inextricably tied to measuring the success of orthopaedic surgery and patient satisfaction. While progress has been made in optimizing the utilization of PROM data, including establishing appropriate PROMs for a procedure and determining the clinical importance of unique tools, if these PROMs are not accurately analyzed and reported, a proportion of patients who do not reach the clinical thresholds may go unnoticed. Furthermore, parameters are unclear for setting a statistically and clinically important PROM threshold along with a minimum period for follow-up data collection.In this forum, we walk through simulated data sets modeling PROMs with the example of total joint arthroplasty. We discuss how the commonly used method of reporting PROMs by mean change can overestimate the treatment effects for the cohort as a whole and fail to capture distinct populations that are below a clinically relevant threshold. We demonstrate that when a study's outcome is PROMs, clinical importance should be reported using clinical thresholds such as the minimum clinically important difference (MCID), the smallest change in the treatment outcome that a patient perceives as beneficial, and the patient acceptable symptom state (PASS), the highest level of symptoms beyond which a patient considers himself or herself well. Finally, we propose a standardized reporting of PROMs that incorporates both the MCID and the PASS, and introduce a "clinical relevance ratio," which relies on a clinically relevant threshold to dichotomize outcomes and reports the number of patients achieving clinical importance at a given time point divided by the total number of patients included in the study. Unlike other common PROM-reporting approaches, the clinical relevance ratio is not skewed by patients who are lost to follow-up with increased time.

Abstract
PURPOSE To establish thresholds for improvement in patient-reported outcome scores that correspond with clinically significant outcomes (CSOs) including the minimal clinically important difference (MCID), substantial clinical benefit (SCB), and patient acceptable symptomatic state (PASS) for Patient-Reported Outcomes Measurement Information System (PROMIS) upper extremity (UE) computer adaptive testing (CAT) and pain interference (PIF) CAT after biceps tenodesis (BT) and to assess patient variables that are associated with achieving these outcomes. METHODS After institutional review board approval was obtained, a prospectively maintained institutional database was queried for patients undergoing BT between December 2017 and August 2019. Patients undergoing BT in isolation or BT in conjunction with rotator cuff debridement, SLAP repair, subacromial decompression, or distal clavicle excision were included in the analysis. Anchor- and distribution-based methods were used to calculate the MCID whereas an anchor-based method was used to calculate SCB and the PASS for PROMIS UE CAT and PIF CAT. RESULTS A total of 112 patients (86.8% follow-up) who underwent BT were included for analysis. The MCID, net SCB, absolute SCB, and PASS for PROMIS UE CAT were 4.02, 9.25, 43.4, and 41.1, respectively. The MCID, net SCB, absolute SCB, and PASS for PROMIS PIF CAT were -4.12, -10.7, 52.4, and 52.4, respectively. Higher preoperative UE CAT and PIF CAT scores, preoperative opioid use, depression, and living alone were negative predictors of CSO achievement. Male sex and regular participation in exercise were positive predictors of CSO achievement. CONCLUSIONS Patients with higher preoperative UE scores were less likely to achieve the MCID (odds ratio [OR], 0.84), whereas patients with higher preoperative PIF scores were less likely to achieve absolute SCB and the PASS (OR, 0.83-0.89). Most patients achieved the MCID for PIF CAT (70.5%) and UE CAT (62.5%) at final follow-up. Male sex (OR, 4.38-9.15) and regular exercise participation (OR, 6.45-18.94) positively predicted CSO achievement, whereas preoperative opioid use (OR, 0.06), depression (OR, 0.23), and living alone (OR, 0.90) were negative predictors of CSO achievement.

Abstract
AIMS To investigate the impact of the Charlson and Elixhauser comorbidity indices on patient-reported outcomes measures (PROMs) following shoulder arthroplasty. METHODS Patients undergoing total shoulder arthroplasty (TSA), reverse shoulder arthroplasty (RSA), or hemiarthroplasty (HA) from 2016 to 2018 were identified, along with the Charlson and Elixhauser comorbidities listed as their secondary diagnoses in the electronic medical records. Patients were matched to our institution's registry to obtain their PROMs, including shoulder-specific (American Shoulder and Elbow Society (ASES) and Shoulder Activity Scale (SAS)) and general health scales (12-Item Short Form Survey (SF-12) and Patient-Reported Outcomes Measurement Information System-Pain Interference). Linear regression models adjusting for age and sex were used to evaluate the association between increasing number of comorbidities and PROM scores. A total of 1,817 shoulder arthroplasties were performed: 1,017 (56%) TSA, 726 (40%) RSA, and 74 (4%) HA. The mean age was 67 years (SD 10), and 936 (52%) of the patients were female. RESULTS The most common comorbidities were obesity (1,256, 69%) and hypertension (990, 55%). Patients with more comorbidities had lower ASES and SAS scores at baseline (p < 0.001). Elixhauser comorbidities continued to negatively impact ASES and SAS scores at one year (p = 0.002) and two-year follow-up (p = 0.002). Patients with more comorbidities reported greater pain interference on PROMIS at baseline (p = 0.007), but not at two years. Higher number of Charlson comorbidities were associated with lower scores on the SF-12 mental component at baseline (p < 0.001) and two years (p = 0.020). Higher number of Elixhauser comorbidities were associated with lower SF-12 physical component scores at baseline (p < 0.001) and two years (p = 0.004). CONCLUSION Higher number of comorbidities was associated with lower baseline scores and worse outcomes on both shoulder-specific and general health PROMs. The presence of specific comorbidities may be used during shared decision-making to manage expectations for patients undergoing shoulder arthroplasty.

Abstract
BACKGROUND Defining success in hip arthroscopy through patient-reported outcome measures (PROMs) is complicated by the wide range of available questionnaires and overwhelming amount of information on how to interpret scores. The minimal clinically important difference (MCID), patient acceptable symptom state (PASS), and substantial clinical benefit (SCB) are collectively known as clinically important outcome values (CIOVs). These CIOVs provide benchmarks for meaningful improvement. The aims of this review were to update the evidence regarding joint-specific PROMs used for hip arthroscopy and to collate available CIOVs in this population. METHODS A systematic review of MEDLINE and Embase databases was performed to identify studies reporting measurement properties of PROMs utilized for hip arthroscopy. Metrics of reliability, validity, and responsiveness were extracted and graded according to an international Delphi study. Questionnaire interpretability was evaluated through CIOVs. RESULTS Twenty-six studies were reviewed. One study validated a novel questionnaire, 3 studies validated existing questionnaires, and 22 studies reported CIOVs. The most evidence supporting interpretability was found for the Hip Outcome Score (HOS, 11 studies), modified Harris hip score (mHHS, 10 studies), and International Hip Outcome Tool-12 (iHOT-12, 9 studies). Scores indicative of the smallest perceptible versus substantial clinically relevant changes were reported for the iHOT-12 (12 to 15 versus 22 to 28), iHOT-33 (10 to 12 versus 25 to 26), HOS-Activities of Daily Living (HOS-ADL, 9 to 10 versus 10 to 16), HOS-Sports (14 to 15 versus 25 to 30), and mHHS (7 to 13 versus 20 to 23). Absolute postoperative scores indicative of an unsatisfactory versus a desirable outcome were reported for the iHOT-12 (below 56 to 63 versus above 86 to 88), iHOT-33 (below 58 versus above 64 to 82), HOS-ADL (below 87 to 92 versus above 94), HOS-Sports (below 72 to 80 versus above 78 to 86), and mHHS (below 74 to 85 versus above 83 to 95). CONCLUSIONS Six questionnaires had reported clinically important outcome thresholds, with the HOS, mHHS, and iHOT-12 having the most information to support score interpretation. Thresholds for the HOS, mHHS, iHOT-12, and iHOT-33 describe desirable absolute PROM scores and minimum and substantial change scores within 5 years following hip arthroscopy. Despite substantial heterogeneity in calculation methodology, included cohorts, and follow-up time, available interpretability values could be meaningfully summarized. CLINICAL RELEVANCE In light of increasing use of PROMs in orthopaedics, a summary of the available CIOVs provides guidance for clinicians in mapping numerical scores from PROMs onto clinical benchmarks.

Abstract
BACKGROUND Despite the growing frequency of revision total knee arthroplasty (rTKA), there is limited information regarding patient-reported outcome measures (PROMs) after that procedure. Therefore, the purpose of this study was to determine (1) PROM improvements in pain, function, quality of life (QOL), and global health and (2) predictors of PROMs for patients undergoing aseptic rTKA as determined using a multilevel model with patients nested within surgeons. METHODS A prospective cohort of 246 patients who underwent aseptic rTKA from January 2016 to December 2017 and had baseline and 1-year postoperative PROMs were analyzed. The most common surgical indications were aseptic loosening (n = 109), instability (n = 73), and implant failure (n = 64). The PROMs included in this study were the Knee injury and Osteoarthritis Outcome Score (KOOS)-Pain, -Physical Function Short Form (PS), and -Quality of Life (QOL) as well as the Veterans Rand-12 (VR-12) Physical Component Summary (PCS) and Mental Component Summary (MCS). Multivariable linear regression models with patients nested within surgeons were constructed for predicting change in PROMs from baseline to 1 year. RESULTS The mean 1-year postoperative improvements in the KOOS-Pain and PS PROMs were 30.3 and 19.15 points, respectively, for the overall rTKA series. Improvement in the KOOS-Pain was associated with older age, baseline arthrofibrosis, lower baseline pain, and non-Medicare/Medicaid insurance and worsening of the scores was associated with multiple prior surgical procedures and instability. Improvement in the KOOS-PS was associated with baseline arthrofibrosis and female sex and worsening was associated with limited baseline function, an instability diagnosis, multiple prior surgical procedures, and increased hospital length of stay (LOS). Overall, the mean KOOS-QOL improved by 29.7 points. Although the mean VR-12 PCS improved, 54.9% of the patients saw no clinical improvement. Additionally, only 31.3% of the patients reported improvements in the VR-12 MCS. A multilevel mixed-effects model with patients/operations nested within surgeons demonstrated that the differences in the surgeons' results were minimal and explained only ∼1.86%, ∼1.12%, and ∼1.65% of the KOOS-Pain, KOOS-PS, and KOOS-QOL variance that was not explained by other predictors, respectively. CONCLUSIONS Overall, patients undergoing aseptic rTKA had improvements in pain, function, and QOL PROMs at 1 year. Although overall QOL improved, other global-health PROMs remained unchanged. The associations highlighted in this study can help guide the preoperative clinical decision-making process by setting expectations before aseptic rTKA. LEVEL OF EVIDENCE Therapeutic Level IV.

Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health Short Forms Demonstrate Responsiveness in Patients Undergoing Knee Arthroplasty. J Arthroplasty 2020; 35:1540-1544. [PMID: 32037211 DOI: 10.1016/j.arth.2020.01.032] [Citation(s) in RCA: 51] [Impact Index Per Article: 12.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2019] [Revised: 12/26/2019] [Accepted: 01/14/2020] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND The Patient-Reported Outcomes Measurement Information System (PROMIS) is an alternative to legacy outcome metrics. We investigated the relationship between Knee Injury and Osteoarthritis Outcomes Score for Joint Replacement (KOOS-JR) and PROMIS Global Health forms of Physical Health (PH) and Mental Health (MH) in knee arthroplasty patients. METHODS This is a retrospective cohort study of knee arthroplasty patients from December 2017 through April 2019 who had surveys collected preoperatively and postoperatively. We excluded patients undergoing revision surgery. Outcome scores were analyzed for responsiveness, effect size index (ESI), minimal clinically important difference (MCID), and correlation with each other through 12 months postoperatively. RESULTS A total of 875 patients were included. Floor and ceiling effects were 0% for PROMIS-PH. Postoperative PROMIS-PH and KOOS-JR scores significantly correlated with one another and increased from baseline at each postoperative time point (P < .001 for all). PROMIS-MH did not change between time points (P > .05). PROMIS-PH showed moderate responsiveness at 1 and 3 months (ESI >0.2) and excellent responsiveness at 6 and 12 months (ESI >0.8), whereas KOOS-JR was responsive at all time points (ESI >0.8). The MCID of PROMIS-PH correlated significantly with KOOS-JR, and a preoperative PROMIS-PH score of less than 32.5 predicted achieving MCID with 97% specificity. CONCLUSION PROMIS global health forms are a valid metric which capture patient outcomes and correlate with KOOS-JR scores after knee arthroplasty. Although KOOS-JR may be more responsive in the early postoperative time period, both measures show excellent responsiveness at 6 and 12 months after knee arthroplasty.
