The purpose of this study was to examine the role of psychosocial factors in the discordance between perceived and observed physical disability in patients with osteoarthritis of the hip or knee joint. This was a cross-sectional study of patients seen for consideration of joint arthroplasty surgery. Patients completed a psychosocial outcome measure, a patient self-reported functional scale, and two performance-based tests. Data of 121 patients, mean age, 67 (8), 81 (67%) females were used for analysis. The fear avoidance and positive affect domains had the strongest association with the discordance between the self-report and both performance outcome measures. Age, gender, and severity of osteoarthritis were associated with discordance in relation to walking. Fear avoidance beliefs and positive affect play important roles in perception of pain and function. Age, gender, and severity of arthritis should be taken into consideration for a more holistic approach to arthritis care., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose: The primary purpose of this study was to validate an appropriateness decision-aid tool as a part of engaging patients with glenohumeral arthritis in their surgical management. The associations between the final decision to have surgery and patient characteristics were examined., Materials and Methods: This was an observational study. The demographics, overall health, patient-specific risk profile, expectations, and health-related quality of life were documented. Visual analog scale and the American Shoulder & Elbow Surgeon (ASES) measured pain and functional disability, respectively. Clinical and imaging examination documented clinical findings and extent of degenerative arthritis and cuff tear arthropathy. Appropriateness for arthroplasty surgery was documented by a 5-item Likert response survey and the final decision was documented as ready, not-ready, and would like to further discuss., Results: Eighty patients, 38 women (47.5%), mean age: 72(8) participated in the study. The appropriateness decision aid showed excellent discriminate validity (area under the receiver operating characteristic curve value of 0.93) in differentiating between patients who were "ready" and those who were "not-ready" to have surgery. Gender ( P   =  0.037), overall health ( P   =  .024), strength in external rotation ( P   =  .002), pain severity ( P   =  .001), ASES score ( P  < .0001), and expectations ( P   =  .024) were contributing factors to the decision to have surgery. Imaging findings did not play a significant role in the final decision to have surgery., Conclusions: A 5-item tool showed excellent validity in differentiating patients who were ready to have surgery versus those who were not. Patient's gender, expectations, strength, and self-reported outcomes were important factors in reaching the final decision., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2023.)

Background: Patients with complete rotator cuff tears who fail a course of nonoperative therapy can benefit from surgical repair., Purpose: This randomized trial compared mini-open (MO) versus all-arthroscopic (AA) rotator cuff repair., Study Design: Randomized controlled trial; Level of evidence, 1., Methods: Patients with rotator cuff tears were randomized to undergo MO or AA repair at 9 centers by 23 surgeons. The primary outcome (Western Ontario Rotator Cuff Index [WORC]) and secondary outcomes (American Shoulder and Elbow Surgeons [ASES] score, Shoulder Pain and Disability Index [SPADI] pain subscale, 12-Item Short Form Health Survey [SF-12], reported medication use, adverse events), as well as measurements of range of motion and strength, were collected at 1 month before surgery; at 2 and 6 weeks postoperatively; and at 3, 6, 12, 18, and 24 months postoperatively. A blinded radiologist evaluated rotator cuff integrity on magnetic resonance imaging (MRI) at baseline and 1 year. Intention-to-treat analysis of covariance with the preoperative WORC score, age, and tear size as covariates assessed continuous outcomes. Sex differences were assessed. A meta-analysis synthesized the primary outcome between MO and AA repair with previous trials., Results: From 954 patients screened, 411 were ineligible (276 because of recovery with physical therapy), 449 were screened at surgery (175 ineligible), and 274 completed follow-up (138 MO and 136 AA). The AA and MO groups were similar before surgery. WORC scores improved from 40 preoperatively to 89 (AA) and 93 (MO) at 2 years, for an adjusted mean difference of 3.4 (95% CI, -0.4 to 7.2). There were no statistically significant differences between the AA and MO groups at any time point. All secondary patient-reported outcomes were not significantly different between the MO and AA groups, except the 2-year SPADI pain score (8 vs 12, respectively; P = .02). A similar recovery in range of motion and strength occurred in both groups over time. MRI indicated minimal improvement in muscle relative to fat (AA: n = 3; MO: n = 2), with most worsening (AA: n = 25; MO: n = 24) or remaining unchanged (AA: n = 70; MO: n = 70). Opioid use was significantly reduced after surgery (from 21% to 5%). The meta-analysis indicated no significant standardized mean difference between groups in the primary outcome across all pooled studies (standardized mean difference, -0.06 [95% CI, -0.34 to 0.22])., Conclusion: Both AA and MO rotator cuff repair provide large clinical benefits, with few adverse events. There is strong evidence of equivalent clinical improvements., Trial Registration: NCT00128076.

Purpose: The purpose of this review is to describe the role of altered joint biomechanics in reverse shoulder arthroplasty and to propose a rehabilitation protocol for a cuff-deficient glenohumeral joint based on the current evidence. Methods and Materials: The proposed rehabilitation incorporates the principles of pertinent muscle loading while considering risk factors and surgical complications., Results: In light of altered function of shoulder muscles in reverse arthroplasty, scapular plane abduction should be more often utilized as it better activates deltoid, teres minor, upper trapezius, and serratus anterior. Given the absence of supraspinatus and infraspinatus and reduction of external rotation moment arm of the deltoid in reverse arthroplasty, significant recovery of external rotation may not occur, although an intact teres minor may assist external rotation in the elevated position., Conclusion: Improving the efficiency of deltoid function before and after reverse shoulder arthroplasty is a key factor in the rehabilitation of the cuff deficient shoulders. Performing exercises in scapular plane and higher abduction angles activates deltoid and other important muscles more efficiently and optimizes surgical outcomes., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2021.)

Objectives: It is important for clinicians involved in the care of patients with advanced glenohumeral osteoarthritis to determine clinically significant change when using outcome measures. There is little information on the amount of substantial clinical benefit in shoulder outcomes after shoulder arthroplasty. The purpose of this study was twofold: (1) to quantify substantial clinical benefit for the American Shoulder and Elbow Surgery score, the Constant Murley Score, and the Western Ontario Osteoarthritis of the Shoulder index and (2) to provide estimates of responsiveness and sensitivity to change for these measures following shoulder arthroplasty., Methods: The study involved a secondary analysis of previously collected data. The substantial clinical benefit and responsiveness of the measures were calculated based on external anchors related to change in pain, range of motion, and ability to carry out activities of daily living. The areas under curve and standardized response mean represented responsiveness and sensitivity to change., Results: The data of 159 and 131 patients with complete follow-up at 6 months and 2 years were reviewed. The amount of substantial clinical benefit was dependent on the outcome measure and the external anchor and increased for all measures from 6 months to 2 years. Responsiveness was high (areas under curve > 0.80) at 6 months and further improved at 2 years (areas under curve > 0.88). The standardized response mean values of both time points were over 2.00, indicating high effect sizes. The standardized response means of the Constant Murley Score were statistically significantly higher than the standardized response means of the American Shoulder and Elbow Surgery and Western Ontario Osteoarthritis of the Shoulder., Conclusion: Amount of substantial clinical improvement in pain, range of motion, and activities of daily living following shoulder arthroplasty depends on the type of outcome measure used. All three measures, the American Shoulder and Elbow Surgery, absolute and relative Constant Murley Score, and Western Ontario Osteoarthritis of the Shoulder, demonstrated good to excellent accuracy and optimal standardized response means., Level of Evidence: Level III, Retrospective Cohort study., Competing Interests: Declaration of conflicting interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2020.)

Objectives: It is not clear if using patients with bilateral symptoms would impact the level of disability reported in orthopaedic research. The purposes of this study were to (1) examine the prevalence of bilateral shoulder symptoms (significant pain, stiffness or weakness affecting function) in patients with rotator cuff impingement syndrome, rotator cuff tear and osteoarthritis of the glenohumeral joint, (2) explore risk factors associated with bilateral shoulder symptoms, and (3) examine the impact of symptom bilaterality and hand dominance on pre- and post-operative patient-oriented disability outcomes., Methods: This study involved secondary analysis of prospectively collected data of patients who had undergone shoulder surgery and had returned for their 1-year follow-up. Two outcome measures were collected prior to surgery and at 1-year following surgery: the American Shoulder and Elbow Surgeons and the Constant-Murley Score., Results: Data of 772 patients, 376 (49%) females, 396 males (51%); 288 (impingement syndrome), 332 (rotator cuff tear), and 152 (osteoarthritis) were included in the analysis. There was a statistically significant difference in the prevalence of bilateral symptoms being 44%, 28%, and 22% in the osteoarthritis, impingement syndrome, and rotator cuff tear groups, respectively (p < 0.0001). The prevalence of dominant side involvement was 71%, 67%, and 53% in the rotator cuff tear, impingement syndrome, and osteoarthritis groups (p < 0.0001). Older age and female sex were risk factors for development of bilateral symptoms only in patients with rotator cuff tear. Neither symptom bilaterality nor dominant arm involvement had a negative impact on patient-oriented disability outcome measures prior to or after surgery (p > 0.05)., Conclusion: This study shows that patients with osteoarthritis of the glenohumeral joint have the highest prevalence of bilateral shoulder complaints. The older age and the female sex increased the risk of having bilateral symptoms in patients with rotator cuff tear. Having bilateral shoulder symptoms or dominant side involvement was not associated with higher level of disability prior or after surgery., Competing Interests: Declaration of conflicting interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objectives: The objectives of this study were to (1) examine the overall recovery and satisfaction following an expedited rotator cuff (RC) decompression or repair at 3-6 months and (2) explore group differences (repair vs. decompression) in demographics, clinical, disability, and psychosocial factors., Methods: This was a prospective longitudinal study of injured workers whose surgery was expedited. The outcome measures were Quick disabilities of the arm, shoulder, and hand ( QuickDASH), the Hospital Anxiety and Depression Scale (HADS), the readiness for return to work (RRTW) scale, and satisfaction with surgery and overall recovery., Results: Of 118 patients participated in the study, 106 patients, age: 51 (9), 71 males (67%) completed the study. Sixty-four (60%) patients underwent a RC repair and 42 (40%) had RC decompression. Patients improved on average in QuickDASH ( p = 0.004), anxiety ( p = 0.003), and depression scores ( p = 0.004). The majority of patients (75%) were satisfied with surgery. In the decompression group, the pre-contemplation (PC) stage of the RRTW which documents the absence of desire or planning for return to work in the non-working sample ( r = 0.81, p = 0.008) and the uncertain maintenance (UM) stage of the RRTW which explores the worker's struggle to stay at work in the working sample correlated with physical disability as measured by the QuickDASH scores ( r = 0.62, p = 0.0001). In the repair group, the above domains correlated with the depression HADS scores (PC: r = 0.64, p = 0.001 and UM: r = 0.57, p < 0.0001)., Conclusion: Expedited RC surgery improved physical disability and mental well-being and was associated with a relatively high satisfaction at a maximum of 6 months. The poorer report of readiness for return to work was associated with higher physical disability in the decompression group and higher report of depression in the repair group. These differential associations may emphasize the importance of physical versus psychological management in patients with different levels of pathology.
