Review
BACKGROUND
To compare shoulder range of motion (ROM) in dominant vs. nondominant shoulder of competitive tennis players, and to determine whether shoulder ROM is different between younger and older players, or males and females.
METHODS
A search was performed on PubMed, Embase, and Epistemonikos on December 18, 2023. This study conforms to the principles of the Cochrane Collaboration and the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. Clinical studies or case reports on shoulder ROM including external rotation (ER; shoulder at 90° of abduction) and internal rotation (IR) in competitive, elite, or professional tennis players.
RESULTS
We found 25 eligible studies that reported on a total of 18,534 tennis players, of which 20 studies reported the ROM for the dominant and nondominant side. Comparing dominant vs. nondominant shoulders revealed that dominant shoulders had significantly smaller IR (53.0° vs. 62.6°; < .001). Comparing adults vs. children revealed that adults have significantly smaller IR (44.5° vs. 57.1°; < .001) and ER (95.3° vs. 110.3°; < .001). Comparing females vs. males revealed no significant differences in ER (113.4° vs. 104.9°; = .360) or IR (54.3° vs. 56.4°; = .710).
CONCLUSION
IR in shoulders of tennis players is significantly smaller in dominant vs. nondominant sides (53.0° vs. 62.6°, < .001), and significantly smaller in adults vs. children (44.5° vs. 57.1°, < .001). These findings could be relevant in the context of physical preparation and training of tennis players, to monitor evolution of IR as a result of their sport and/or as they transition from childhood to adulthood.

Review
A systematic review of randomized control trials looking at functional improvement of rotator cuff partial thickness tears following platelet-rich-plasma injection: a comparison of glenohumeral joint vs. subacromial bursa vs. intratendinous injection locations.
BACKGROUND
Prior research has demonstrated that platelet-rich plasma (PRP) has shown promising results in the treatment of knee osteoarthritis, lateral epicondylitis, and rotator cuff disease. However, there is a lack of standardization with PRP regarding its use for partial thickness rotator cuff tears (PTRCTs). The primary objective of this review is to assess the location of PRP injections in the shoulder, and how it corresponds to shoulder functional outcomes in PTRCTs.
METHODS
Data sources included randomized controlled trials (RCTs) conducted between January 2010 and September 2021 with the terms PRP, partial thickness rotator cuff tears, intra-articular injections, subacromial injections, and intratendinous injections. Major inclusion criteria: partial thickness rotator cuff tears only, functional outcome scores pre-injection and post-injection, minimum 2-month follow-up time, and nonsurgical PRP injections only. Major exclusion criteria: PRP used as an adjunct therapy, full-thickness rotator cuff tears, and surgical intervention before treatment.
RESULTS
A total of 8 RCTs were included which utilized PRP injected into the shoulder for PTRCTs. Studies were grouped by the location of the injection with the following breakdown: 1 glenohumeral joint, 4 subacromial bursa, and 3 intratendinous as the site of injection of PRP. Intra-articular PRP showed a 46.2% improvement ( < .05) in the Disabilities of the Arm, Shoulder, and Hand score at 12-month follow-up, however PRP compared to physical therapy had no statistical difference. For subacromial injections, one study showed no statistical difference between hyaluronic acid and PRP vs PRP, but both groups showed improvement compared to normal saline at 3, 6, and 12 months ( < .05). For intratendinous injections, PRP was found to be superior in the Shoulder Pain and Disability Index scores at 66.1% improvement ( < .05) at 3 months and 71.6% at 6 months ( < .05) after two PRP injections when compared to dry needling. Another study showed a statistically significant difference in ASES score when combining LP-PRP injection intratendinous and subacromial bursa when compared to corticosteroid at 3 months. Furthermore, at 6-month follow-up, the PRP group showed significant improvement in the Oxford Shoulder Score compared to a subacromial bursa corticosteroid group 53.8% vs 31.7% ( < .01).
CONCLUSION
Based on our review of current literature, there is inconclusive evidence of the ideal location to inject PRP when partial rotator cuff tear is present. Despite PRP showing improved functional outcomes in patients diagnosed with PTRCT regardless of the injection site, more research is needed to figure out the optimal concentration of PRP, frequency of injection, and who are ideal candidates when utilizing PRP for PTRCTs.

Review
BACKGROUND
Therapeutic exercise has been considered a useful tool to rehabilitate shoulder pain, namely through its influence on scapular dynamics. Accordingly, the effectiveness of scapular therapeutic exercise needs to be explored. The present study aims to evaluate the effectiveness of scapular therapeutic exercises in shoulder pain and to identify the most effective exercise type (focal or multijoint) and ways of delivering them (as dose and progression).
METHODS
Search was conducted at EMBASE, Cochrane Library, MEDLINE via PubMed, Web of Science, PEDro (Physiotherapy Evidence Database), and trial registration databases. The meta-analysis considered randomized controlled/crossover trials that compared the effect of scapular exercises against other types of intervention in the shoulder pain, shoulder function, scapular motion, and/or muscular activity. The risk of bias was assessed through the PEDro scale.
RESULTS
From the 8318 records identified, 8 (high to low risk of bias- scoring from 4 to 8 on the PEDro scale) were included. The overall data, before sensitivity analysis, indicated that the scapular therapeutic exercises are: a) more effective than comparators in improving shoulder function (standardized mean difference [SMD] = 0.52 [95% Cl: 0.05, 0.99], = .03, = 76%); and b) as effective as comparators in reducing shoulder pain (SMD = 0.32 [95% Cl: -0.09, 0.73], = .13, = 70%). Subgroup analysis revealed that scapular exercises are more effective in improving shoulder function when the program duration is equal to or higher than 6 weeks (SMD = 0.43 [95% Cl: 0.09, 0.76] = .01, = 21%) and/or when the maximum number of exercise repetitions per session is lower than 30 (SMD = 0.79 [95% Cl: 0.15, 1.42], = .01, = 77%). Only 1 study considered scapular motion as an outcome measure, revealing therapeutic exercise effectiveness to improve scapular range of motion.
CONCLUSIONS
Intervention programs involving scapular therapeutic exercises are effective in improving shoulder function, presenting benefits when performed for 6 or more weeks and/or when used up to a maximum of 30 repetitions per exercise, per session.

Meta-Analysis
BACKGROUND
Rotator cuff tendinopathy (RCT) is a widespread musculoskeletal disorder and a primary cause of shoulder pain and limited function. The resulting pain and limited functionality have a detrimental impact on the overall quality of life. The purpose of this study was to perform a systematic review of the effects of extracorporeal shock wave therapy (ESWT) for RCT.
METHODS
The literature search was conducted on the following databases from inception to February 20, 2024: PubMed, Web of Science, the Cochrane Library, Scopus, MEDLINE, EMBASE, EBSCO, and China National Knowledge Infrastructure (CNKI) were checked to identify the potential studies exploring the effect of ESWT for the treatment of Rotator cuff tendinopathy (Calcification or non-calcification), control group for sham, other treatments (including placebo), without restriction of date, language. Two researchers independently screened literature, extracted data, evaluated the risk of bias in the included studies, and performed meta-analysis using RevMan 5.3 software.
RESULTS
A total of 16 RCTs with 1093 patients were included. The results showed that compared with the control group, ESWT for pain score Visual Analogue Scale/Score (VAS) (SMD = -1.95, 95% CI -2.47, -1.41, P < 0.00001), function score Constant-Murley score (CMS) (SMD = 1.30, 95% CI 0.67, 1.92, P < 0.00001), University of California Los Angeles score (UCLA) (SMD = 2.69, 95% CI 1.64, 3.74, P < 0.00001), American Shoulder and Elbow Surgeons form (ASES) (SMD = 1.29, 95% CI 0.93, 1.65, P < 0.00001), Range of motion (ROM) External rotation (SMD = 1.00, 95% CI 0.29, 1.72, P = 0.02), Total effective rate (TER) (OR = 3.64, 95% CI 1.85, 7.14, P = 0.0002), the differences in the above results were statistically significant. But ROM-Abduction (SMD = 0.72, 95% CI -0.22, 1.66, P = 0.13), the difference was not statistically significant.
CONCLUSION
Currently limited evidence suggests that, compared with the control group, ESWT can provide better pain relief, functional recovery, and maintenance of function in patients with RCT.

BACKGROUND
Artificial intelligence (AI) uses computer systems to simulate cognitive capacities to accomplish goals like problem-solving and decision-making. Machine learning (ML), a branch of AI, makes algorithms find connections between preset variables, thereby producing prediction models. ML can aid shoulder surgeons in determining which patients may be susceptible to worse outcomes and complications following shoulder arthroplasty (SA) and align patient expectations following SA. However, limited literature is available on ML utilization in total shoulder arthroplasty (TSA) and reverse TSA.
METHODS
A systematic literature review in accordance with PRISMA guidelines was performed to identify primary research articles evaluating ML's ability to predict SA outcomes. With duplicates removed, the initial query yielded 327 articles, and after applying inclusion and exclusion criteria, 12 articles that had at least 1 month follow-up time were included.
RESULTS
ML can predict 30-day postoperative complications with a 90% accuracy, postoperative range of motion with a higher-than-85% accuracy, and clinical improvement in patient-reported outcome measures above minimal clinically important differences with a 93%-99% accuracy. ML can predict length of stay, operative time, discharge disposition, and hospitalization costs.
CONCLUSION
ML can accurately predict outcomes and complications following SA and healthcare utilization. Outcomes are highly dependent on the type of algorithms used, data input, and features selected for the model.

Meta-Analysis
Arthroscopic rotator cuff repair combined with platelet-rich plasma products can reduce the rate of retearing and improve clinical outcomes: A meta-analysis of randomized controlled trials.
BACKGROUND
Although several studies on the potential benefits of protein-rich plasma (PRP) therapy for rotator cuff injuries have been published, the results have been conflicting. Therefore, this study aimed to determine whether PRP is beneficial for the prevention of retears after arthroscopic rotator cuff repair (ARCR).
METHODS
Two reviewers conducted independent literature searches based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Randomized controlled trials (RCTs) comparing a PRP treatment group with a control group were included. The quality of evidence was assessed using the Cochrane Collaboration Risk of Bias Tool. Clinical outcomes were compared using the risk ratio (RR) for dichotomous variables and weighted mean difference (WMD) for continuous variables. Statistical significance was set at P < .05.
RESULTS
This review included 21 RCTs (1359 patients). Significant results were noted in favor of PRP treatment compared with controls based on retearing rates (16.5% vs 23.6%, respectively; P = .002) and the Constant score in the short term (WMD: 1.98; 95% confidence interval [CI], 0.27-3.70; I2 = 0%; P = .02), medium term and long term (WMD: 2.56 [95% CI: 1.57-3.55]; I2 = 2%; P < .001); the University of California, Los Angeles score in the short term (WMD: 1.14 [95% CI: 0.43-1.85]; I2 = 25%; P = .002) but not in the medium and long term (WMD: 0.66 [95% CI: -0.16 to 1.48]; I2 = 57%; P = .11); and the visual analog scale score in the short term (WMD: -0.63 [95% CI: -0.83 to-0.43]; I2 = 41%; P < .001), medium and long term (WMD: -0.12 [95% CI: -0.19 to-0.05]; I2 = 0%; P = .008). There was no significant difference in American Shoulder and Elbow Surgeons scores between the treatment and control groups in the short term (WMD: -0.48 [95% CI: -2.80 to 1.85]; I2 = 22%; P = .69) or medium and long term (WMD: 0.92 [95% CI: -1.56 to 3.39]; I2 = 40%; P = .47).
CONCLUSION
Intraoperative use of PRP reduces the risk of rotator cuff repair failure, improves clinical outcomes, and reduces recurrence rates.

Review
PURPOSE
To evaluate the current body of evidence surrounding the diagnosis, management, and clinical outcomes of adhesions that developed after hip arthroscopy (HA).
METHODS
A systematic search of the MEDLINE, Embase, Web of Science, and CENTRAL (Cochrane Central Register of Controlled Trials) databases was designed and conducted in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. Eligible studies included patients with confirmed adhesions after HA that reported one or more of the following: (1) diagnostic procedures and criteria used; (2) indications for and details surrounding surgical management; and (3) clinical outcomes after the operative management of adhesions (e.g., patient-reported outcome measures).
RESULTS
Nineteen studies involving a total of 4,145 patients (4,211 hips; 38% female sex) were included in this review. The quality of evidence was found to be fair for both comparative studies (mean, 17; range, 13-21) and noncomparative studies (mean, 10; range, 5-12) according to the Methodological Index for Non-randomized Studies (MINORS) instrument, with the level of evidence ranging from IIB to IV. Adhesions were often diagnosed intraoperatively at the time of revision surgery (10 of 19 studies, 53%), with only 3 studies specifying the criteria used to adjudicate adhesions. The most common indication for operative management (i.e., release or lysis of adhesions) was persistent pain (9 of 19, 47%), but this was often grossly stated for revision HA rather than being specific to adhesions. Patient-reported outcome measures were the most reported postoperative outcomes (9 of 19, 47%) and generally showed significant improvement from preoperative assessment across the short-term follow-up period (range, 24.5-38.1 months). There was a paucity of objective measures of clinical improvement (3 of 19, 16%) and of mid- and long-term follow-up (i.e., 5-7 years and ≥10 years, respectively).
CONCLUSIONS
Despite the growing body of evidence suggesting that adhesions are highly contributory to revision HA, there is ambiguity in the diagnostic approach and indications for operative management of adhesions. Additionally, although the operative management of adhesions after HA has shown satisfactory clinical outcomes in the short term, there is a paucity of research elucidating the mid- to long-term outcomes, as well as minimal use of objective assessment of clinical improvement (e.g., biomechanics).

Review
OBJECTIVE
The aim of this systematic review is to study the subdiaphragmatic anatomy of the phrenic nerve.
MATERIALS AND METHODS
A computerised systematic search of the Web of Science database was conducted. The key terms used were phrenic nerve, subdiaphragmat*, esophag*, liver, stomach, pancre*, duoden*, intestin*, bowel, gangli*, biliar*, Oddi, gallbladder, peritone*, spleen, splenic, hepat*, Glisson, falciform, coronary ligament, kidney, suprarenal, and adrenal. The 'cited-by' articles were also reviewed to ensure that all appropriate studies were included.
RESULTS
A total of one thousand three hundred and thirty articles were found, of which eighteen met the inclusion and exclusion criteria. The Quality Appraisal for Cadaveric Studies scale revealed substantial to excellent methodological quality of human studies, while a modified version of the Systematic Review Centre for Laboratory Animal Experimentation Risk of Bias Tool denoted poor methodological quality of animal studies. According to human studies, phrenic supply has been demonstrated for the gastro-esophageal junction, stomach, celiac ganglia, liver and its coronary ligament, inferior vena cava, gallbladder and adrenal glands, with half of the human samples studied presenting phrenic nerve connections with any subdiaphragmatic structure.
CONCLUSIONS
This review provides the first systematic evidence of subdiaphragmatic phrenic nerve supply and connections. This is of interest to professionals who care for people suffering from neck and shoulder pain, as well as patients with peridiaphragmatic disorders or hiccups. However, there are controversies about the autonomic or sensory nature of this supply.

AIMS
The aims of this study were to identify and evaluate the current literature examining the prognostic factors which are associated with failure of total elbow arthroplasty (TEA).
METHODS
Electronic literature searches were conducted using MEDLINE, Embase, PubMed, and Cochrane. All studies reporting prognostic estimates for factors associated with the revision of a primary TEA were included. The risk of bias was assessed using the Quality In Prognosis Studies (QUIPS) tool, and the quality of evidence was assessed using the modified Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) framework. Due to low quality of the evidence and the heterogeneous nature of the studies, a narrative synthesis was used.
RESULTS
A total of 19 studies met the inclusion criteria, investigating 28 possible prognostic factors. Most QUIPS domains (84%) were rated as moderate to high risk of bias. The quality of the evidence was low or very low for all prognostic factors. In low-quality evidence, prognostic factors with consistent associations with failure of TEA in more than one study were: the sequelae of trauma leading to TEA, either independently or combined with acute trauma, and male sex. Several other studies investigating sex reported no association. The evidence for other factors was of very low quality and mostly involved exploratory studies.
CONCLUSION
The current evidence investigating the prognostic factors associated with failure of TEA is of low or very low quality, and studies generally have a moderate to high risk of bias. Prognostic factors are subject to uncertainty, should be interpreted with caution, and are of little clinical value. Higher-quality evidence is required to determine robust prognostic factors for failure of TEA.

To critically evaluate the effects of manual therapy (MT) on pain and functional improvement in patients with rotator cuff injury (RCI), a systematic review of all randomized controlled trials (RCTs) on MT for RCI was conducted in the following databases: PubMed, Cochrane Central Register of Controlled Trials, Embase, Web of Science, Physiotherapy Evidence Database, Chinese National Knowledge Infrastructure, Wan-fang Data, Chinese Scientific Journal Database, and Chinese Biomedical Literature database from inception to March 28, 2023. A total of 1,110 participants from 24 eligible RCTs were included in the analysis. Compared with placebo, MT could not effectively relieve pain [standardized mean difference (SMD)=-0.25; 95% CI: -0.51 to 0.01; P=0.06], although its impact on functional improvement appears limited (SMD=0.20; 95% CI: -0.09 to 0.49; P=0.18). Combining MT with exercise had significant advantages over exercise alone, as combined therapy contributed to both pain reduction (SMD=0.36; 95% CI: 0.08 to 0.64; P=0.01) and functional enhancement (SMD=0.32; 95% CI: 0.11 to 0.52; P=0.002). Furthermore, MT combined with multimodal physiotherapy showed additional benefits in pain reduction (mean difference=1.57; 95% CI: 0.18 to 2.96; P=0.03) and functional improvement (SMD=0.77; 95% CI: 0.43 to 1.12; P<0.0001) compared with multimodal physiotherapy alone. These findings highlight the superior pain alleviation and functional improvement provided by MT when combined with exercise or physiotherapy. Consequently, MT has emerged as a pivotal component of therapeutic intervention for RCI.
