Background
Osteochondral autologous transplant (OAT) is an option in the treatment of pediatric capitellar osteochondritis dissecans (OCD). However, quantifying the improvement in the area of OCD defects contributing to the articular surface after an OAT procedure has not been well documented. The purpose of this study was to use magnetic resonance imaging (MRI) to evaluate changes in the defect area of capitellar OCD lesions in pediatric patients following an OAT procedure using a lateral femoral condyle autograft.
Methods
Pediatric patients with capitellar OCD lesions underwent an OAT from the lateral femoral condyle to the involved capitellum. MRI was obtained preoperatively, 3 months postoperatively, and 12 months postoperatively. Sagittal image slices of the capitellum were analyzed to measure the percentage area of articular cartilage defect compared with a best-fit circle simulating the ideal profile of the capitellum.
Results
Twelve patients met the inclusion criteria for this study. Preoperatively, the average percentage area of defect within each capitellar OCD lesion (compared to the ideal profile) was 16%. At 3 months postoperatively, the average area defect significantly improved to 3% (P < .01) compared to preoperative imaging. One patient (8.3%) had complete filling of their cartilage defect, and 10 patients (83%) had ≤3% area of defect. One patient (8.3%) had subsidence of articular cartilage between their postoperative imaging at 3 months and 12 months. Despite this, there was no significant change in defect area between 3 months and 12 months postoperatively (P = .07).
Conclusion
This radiographic analysis of area restoration following an OAT procedure for pediatric capitellar OCD lesions demonstrates a significant decrease in defect area on the articular surface in postoperative MRI. This study provides further support for the utilization of an OAT procedure for the management of pediatric capitellar OCD lesions.

Background
Shear wave elastography (SWE) is a relatively recent ultrasound imaging technique that uses focused acoustic radiation forces to quantify the elasticity of biological tissues, commonly referred to as ‘elastographic stiffness’. Preliminary data suggest that the elastographic stiffness of a torn supraspinatus tendon may serve as an independent predictor of retear risk following surgical repair. However, the feasibility of obtaining accurate preoperative SWE measurements remains uncertain, as tendon retraction beneath the acromion can limit visualization and reliable assessment.
Methods
This was a prospective cohort study that recruited 60 consecutive patients who had received a diagnosis of supraspinatus tear. SWE imaging was conducted to determine the elastographic stiffness of each patient's torn supraspinatus tendon.
Results
SWE values of the edge of the torn supraspinatus were successfully measured in 59/60 (98%) of cases, resulting in a failure to measure rate of 2%. SWE measurements were not feasible in a single case where the anteroposterior or mediolateral tear lengths were greater than 28 mm. Tendon elastographic stiffness, measured as elasticity (kPa), was inversely correlated with anteroposterior tear length (R2 −.51, P < .001), mediolateral tear length (R2 −.54, P < .001), and patient age (R2 −.27, P < .05).
Conclusion
This study shows that preoperative SWE of the torn supraspinatus tendon is a feasible imaging methodology if the supraspinatus tear is < 30 mm. Patients who had smaller tears and who were younger had greater SWE than older patients with larger tears.
背景剪切波弹性成像(SWE)是一种相对较新的超声成像技术,它使用聚焦声辐射力来量化生物组织的弹性,通常被称为“弹性刚度”。初步数据表明,冈上肌腱撕裂的弹性刚度可以作为手术修复后再撕裂风险的独立预测因子。然而,获得准确的术前SWE测量的可行性仍然不确定,因为肩峰下方的肌腱缩回限制了可视化和可靠的评估。方法:这是一项前瞻性队列研究,招募了60名连续确诊为冈上肌撕裂的患者。进行SWE成像以确定每位患者撕裂的冈上肌腱的弹性刚度。结果59/60(98%)的病例成功测量冈上肌撕裂边缘的sswe值,测量不良率为2%。对于前后或中外侧撕裂长度大于28 mm的单一病例,SWE测量是不可行的。肌腱弹性刚度(kPa)与前后撕裂长度呈负相关(R2−。51, P < .001),中外侧撕裂长度(R2−。54, P < .001),患者年龄(R2−。27, P < 0.05)。结论本研究表明,如果冈上肌腱撕裂为30 mm,术前SWE是一种可行的成像方法。泪点较小的年轻患者的SWE高于泪点较大的老年患者。

Background
Anatomic total shoulder arthroplasty (aTSA) has been proven effective in the treatment of painful end-stage osteoarthritis in patients with intact rotator cuff function. However, elderly patients may have an increased risk of revision, especially when it comes to the risk of revision due to loosening, rotator cuff pathology and periprosthetic fracture. The aim of this study was to investigate revision rates and patient-reported outcomes after aTSA for osteoarthritis in patients who are 75 years or older. We hypothesized that revision rates and patient-reported outcomes were similar for patients aged 55-74 years and 75 years or older.
Methods
This is a registry-based cohort study with data from the Danish Shoulder Arthroplasty Registry. For analysis, 1,884 aTSAs used for osteoarthritis between January 1, 2012, and December 31, 2019, were included. Patients were divided into 2 age groups: 55-74 years and 75 years or older. The Kaplan–Meier method was used to estimate unadjusted cumulative revision rates and a multivariate Cox regression model was used to determine hazard ratios. A multivariable linear regression model was used to compare the Western Ontario Osteoarthritis of the Shoulder Index (WOOS) 1 year postoperatively.
Results
There were 34 (2.5%) patients in the middle-aged group and 8 (1.6%) patients in the older age group who had revision surgery. The hazard ratio for revision was 0.67 for the older age group compared to the middle-aged group (95% confidence interval [CI] 0.31-1.47, P = .32). The unadjusted 2-year and 5-year cumulative revision rates were 2.3% (95% CI 1.4-3.2) and 3.6% (95% CI 2.3-4.9) in the middle-aged group and 1.7% (95% CI 0.4-3.0) and 2.2% (95% CI 0.6-3.8) in the older age group. The mean WOOS score was 84 (standard deviation = 20) in the middle-aged group and 85 (standard deviation = 20) in the older age group. The difference in WOOS between the 2 groups was 1.2 points (95% CI −1.5 to 3.8, P = .40).
Conclusion
We found low short-term revision rates and good patient-reported outcomes for both middle-aged and older patients treated for osteoarthritis using aTSA. The small differences in WOOS between the 2 age groups were not clinically relevant nor statistically significant. aTSA provides good and reliable outcomes in elderly patients with end-stage osteoarthritis, and age alone should not be a reason for opting out aTSA.
背景:原子全肩关节置换术(aTSA)已被证明对肩袖功能完好的患者治疗疼痛性终末期骨关节炎有效。然而,老年患者可能会增加翻修的风险,特别是当由于松动、肩袖病理和假体周围骨折而导致翻修的风险时。本研究的目的是调查75岁及以上骨关节炎患者aTSA后的翻修率和患者报告的结果。我们假设55-74岁和75岁及以上患者的复习率和患者报告的结果相似。方法:这是一项基于登记的队列研究,数据来自丹麦肩关节置换术登记中心。为了进行分析,纳入了2012年1月1日至2019年12月31日期间用于骨关节炎的1,884例atsa。患者分为55 ~ 74岁和75岁及以上两组。Kaplan-Meier法用于估计未调整的累积修正率,多变量Cox回归模型用于确定风险比。采用多变量线性回归模型比较西部安大略骨关节炎术后1年的肩关节指数(WOOS)。结果中老年行翻修手术34例(2.5%),老年行翻修手术8例(1.6%)。与中年组相比,老年组修订后的风险比为0.67(95%可信区间[CI] 0.31-1.47, P = 0.32)。未调整的2年和5年累积修正率在中年组分别为2.3% (95% CI 1.4-3.2)和3.6% (95% CI 2.3-4.9),在老年组分别为1.7% (95% CI 0.4-3.0)和2.2% (95% CI 0.6-3.8)。中年组平均WOOS评分为84(标准差= 20),老年组平均WOOS评分为85(标准差= 20)。两组间wos差异为1.2点(95% CI - 1.5 ~ 3.8, P = 0.40)。结论:我们发现使用aTSA治疗骨关节炎的中老年患者短期翻修率低,患者报告的预后良好。两个年龄组间wos的微小差异无临床相关性,也无统计学意义。aTSA为老年终末期骨关节炎患者提供了良好和可靠的结果,年龄不应成为选择退出aTSA的原因。

Background
Understanding age-related differences in shoulder glenohumeral and scapulothoracic motion has implications for the understanding, treatment, and management of shoulder injuries and diseases. Previous studies have investigated age-related differences, although statically and in single-plane motion. The shoulder, however, is a complex joint capable of a wide range of motion (ROM) and involves coordinated and synchronous movements from both the glenohumeral and scapulothoracic joints. Therefore, the objectives of this study were to measure age-related differences in kinematics of the glenohumeral and scapulothoracic joints during motion, as well as differences in the neutral positioning of the scapula and humerus.
Methods
Thirty-one male participants comprised 2 cohorts based on age (<45 and ≥ 45 years). Participants performed 2 motions, forward elevation (FE) and internal rotation (IR) to the back, with 4-dimensional computed tomography scanning to dynamically track the bones. The kinematics of the humerus and scapula were calculated with 6 degrees of freedom. The neutral position of the scapula and humerus was also calculated based on a static computed tomography scan.
Results
During the FE motion, IR of the humerus was significantly greater (13°, P = .033) in the older cohort while the scapula had significantly more anterior translation (9 mm, P = .022) and medial rotation (9°, P = .021) in the younger cohort. Anterior translation of the humeral head during IR was significantly greater (1 mm, P = .05) in the younger cohort, while scapular superior translation was significantly greater (8 mm, P = .006) in the older cohort. When measuring humeral translation as a percentage of glenoid width rather than absolute translation, the older cohort exhibited significantly less translational ROM during FE (6%, P < .001), (5%, P = .036), (5%, P = .009) and IR (6%, P < .001), (6%, P < .001), (4%, P < .001) in the respective anterior, superior, and lateral directions. Furthermore, compared to the younger cohort, the older cohort had a neutral pose with significantly more superior translation (17 mm, P = .05), lateral rotation (8°, P = .009) and posterior tilting (10°, P < .001) of the scapula, and a more anteriorly positioned humerus (2 mm, P = .007).
Conclusion
Overall, this study found age-related differences in kinematics and neutral positioning of the scapula and humerus, which may help improve understanding of age-related differences in subluxation, diseases, injuries, and ROM.
背景:了解肩部肩关节和肩胛骨运动的年龄相关差异对理解、治疗和管理肩部损伤和疾病具有重要意义。先前的研究已经调查了与年龄相关的差异,尽管是静态的和单平面运动的。然而,肩膀是一个复杂的关节,能够进行大范围的运动(ROM),包括肩关节和肩胛骨关节的协调和同步运动。因此,本研究的目的是测量运动过程中肩胛骨和肩胛骨关节运动学的年龄相关差异,以及肩胛骨和肱骨中性定位的差异。方法31例男性受试者按年龄(≤45岁和≥45岁)分为2组。参与者进行了两种运动,向前抬高(FE)和向后内旋转(IR),并使用四维计算机断层扫描来动态跟踪骨骼。以6个自由度计算肱骨和肩胛骨的运动学。肩胛骨和肱骨的中立位置也是基于静态计算机断层扫描计算的。结果在FE运动过程中,老年组肱骨IR明显增加(13°,P = 0.033),而年轻组肩胛骨前移(9 mm, P = 0.022)和内侧旋转(9°,P = 0.021)明显增加。在IR期间,年轻队列的肱骨头前移位显著增加(1 mm, P = 0.05),而老年队列的肩胛骨上移位显著增加(8 mm, P = 0.006)。当以肩关节宽度的百分比而不是绝对平移来测量肱骨平移时,老年队列在FE (6%, P < 001)、(5%,P = 0.036)、(5%,P = 0.009)和IR (6%, P < 001)、(6%,P < 001)、(4%,P < 001)期间在各自的前、上、外侧方向上表现出明显更少的平移ROM。此外,与年轻队列相比,老年队列具有中性姿势,肩胛骨的平移(17 mm, P = 0.05),侧旋(8°,P = 0.009)和后倾(10°,P = 0.001)明显更好,肱骨位置更前(2 mm, P = 0.007)。总的来说,本研究发现了肩胛骨和肱骨的运动学和中性定位的年龄相关差异,这可能有助于提高对半脱位、疾病、损伤和ROM的年龄相关差异的理解。

Background
Prior studies have shown that testosterone replacement therapy (TRT) may be a risk-factor for complications after rotator cuff repair (RCR). This study evaluated complication rates among male RCR patients with and without a history of TRT preoperatively.
Methods
A retrospective review of 33,032 male patients undergoing RCR in the PearlDiver database was performed. Patients receiving TRT within 1-year of surgery were propensity score matched 1:3 to those not receiving TRT, 8,258 TRT, and 24,774 no-TRT patients were included. Univariate and multivariate analyses were performed to compare outcomes between groups.
Results
After controlling for decreased libido, benign prostatic hypertrophy, tobacco use, alcohol disorders, liver disease, rheumatologic disease, and preoperative steroid injections, TRT patients were more likely to be readmitted within 90 days (odds ratio [OR]: 1.26, P = .013). Within 2 years postoperatively, TRT patients were more likely to undergo (OR: 1.70, P < .001) or revision RCR (OR: 1.53, P < .001) and to have prolonged opioid use (OR: 1.32, P < .001), frozen shoulder (OR: 1.37, P < .001), and stroke/myocardial infarction (OR: 1.20, P < .001). Patients whose last TRT fill was within 6 months prior to surgery had higher rates of 90-day readmission (2.1% vs. 1.3%; P = .048), prolonged opioid use at 2 years (66.6% vs. 62.1%; P = .002), revision RCR at 2 years (13.1% vs. 8.7%; P < .001), and increased 2-year cost ($18,740 vs. $16,006; P < .001) compared to those whose last fill was 6-12 months preoperatively.
Conclusion
TRT within 1 year of RCR appears to be a risk factor for multiple postoperative complications and subsequent shoulder surgery. Cessation of TRT prior to RCR should be considered on a patient-specific basis.
先前的研究表明,睾酮替代疗法(TRT)可能是肩袖修复(RCR)后并发症的危险因素。本研究评估术前有或无TRT史的男性RCR患者的并发症发生率。方法对PearlDiver数据库中33032例男性RCR患者进行回顾性分析。手术1年内接受TRT的患者与未接受TRT的患者倾向评分匹配1:3,包括8,258例TRT患者和24,774例未接受TRT的患者。进行单因素和多因素分析比较两组间的结果。结果在控制性欲下降、良性前列腺肥大、吸烟、酒精障碍、肝脏疾病、风湿病和术前类固醇注射后,TRT患者在90天内再入院的可能性更大(优势比[OR]: 1.26, P = 0.013)。在术后2年内,TRT患者更有可能发生(OR: 1.70, P < 0.001)或修正RCR (OR: 1.53, P < 0.001),并长期使用阿片类药物(OR: 1.32, P < 0.001),肩周炎(OR: 1.37, P < 0.001)和中风/心肌梗死(OR: 1.20, P < 0.001)。最后一次TRT填充在术前6个月内的患者与术前6-12个月的患者相比,90天再入院率(2.1%对1.3%,P = 0.048), 2年阿片类药物使用时间延长(66.6%对62.1%,P = 0.002), 2年修订RCR(13.1%对8.7%,P < 0.001), 2年费用增加(18,740美元对16,006美元,P < 001)。结论RCR术后1年内trt是多发术后并发症及后续肩部手术的危险因素。在RCR之前停止TRT应根据患者的具体情况进行考虑。

The middle glenohumeral ligament (MGHL) is the least well characterized glenohumeral ligament and its distal insertion remains matter of debate. The aim of this study was to describe the histological features of the distal insertion of the MGHL and its interactions with the subscapularis tendon. Our hypothesis was that the MGHL inserts distally on the articular surface of the subscapularis tendon.
Methods
Macroscopic and histological analysis of the insertion of the MGHL was performed in 16 shoulders obtained from 10 fresh cadaver dissections from a posterior approach. Macroscopic analysis involved observation of the distal insertion of the MGHL and measurement of its distance from the humerus. The distal insertion site was then extracted without bone, fixed in paraffin and stained with hematoxylin-eosin-saffron for histological analysis of longitudinal sections of the MGHL.
Results
The MGHL inserted macroscopically into the subscapularis tendon in all 16 shoulders, at a mean distance of 13 mm (range, 5-30 mm) from the humerus. Histological analysis revealed that the MGHL inserted on the deep layer (articular surface) of the subscapularis in all 16 shoulders, at a distance from the humerus. The junction angle was acute in all cases. Two different connection mechanisms were observed. While a majority of MGHL collagen fibers extended into the articular capsule, increasing its thickness, the remaining MGHL collagen fibers penetrated into the subscapularis tendon in the longitudinal direction of the ligament, mingling with the larger perpendicular collagen bundles of the subscapularis tendon. The junction was in some cases in the subscapularis tendon and in others in the subscapularis myotendinous junction.
Conclusion
The anatomically exceptional ligament-to-tendon distal insertion of the MGHL into the subscapularis was histologically confirmed in all. These findings support recent results indicating that the MGHL does not insert onto the humerus but into the articular surface of the subscapularis tendon, forming a blend of ligament fibers up to its terminal insertion on the lesser tuberosity. These results suggest that MGHL mechanical constraints are transferred into the subscapularis tendon rather than at the bony insertion on the lesser tuberosity.

Background
Shoulder surgeons often offer markedly different treatment recommendations for a given patient and pathophysiology within the context of a common body of evidence. Prior beliefs and cognitive bias may contribute to this variability. Using Bayesian decision theory informed by principles of behavioral science, we modeled how surgeons with different initial beliefs and degrees of bias update their treatment preferences in response to new evidence comparing anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA) when making surgery recommendations for advanced primary glenohumeral osteoarthritis.
Methods
We developed a Bayesian simulation involving 3 hypothetical surgeons with distinct initial beliefs: aTSA Loyalist (90% belief aTSA is superior), Neutral Thinker (50%), and rTSA Advocate (10% belief aTSA is superior) and varying degrees of confirmation bias (eg, the selective discounting of evidence that contradicts one's current belief). Each surgeon was sequentially exposed to 10 simulated randomized trials modestly favoring rTSA, with belief trajectories updated after each trial under 2 conditions: (1) an unbiased scenario, in which all new evidence was weighted at face value, and (2) a biased scenario, in which disconfirming evidence was systematically downweighted.
Results
Under a condition simulating no confirmation bias, all surgeons gradually shifted toward lower belief in aTSA superiority as they reviewed the 10 rTSA-favoring trials: the aTSA Loyalist moved from about 90% to 25% confidence in aTSA, the Neutral Thinker from 50% to 2.0%, and the rTSA Advocate from 10% to 1.2%. Under biased conditions, belief change was markedly reduced for the aTSA Loyalist, who remained 64% confident in aTSA superiority despite consistent rTSA-favoring evidence. Changes for the rTSA Advocate (10%-1.2%) and Neutral Thinker (50%-2.3%) were largely unchanged.
Conclusion
This Bayesian simulation provides a practical framework to demonstrate how prior beliefs and cognitive bias can markedly influence the way shoulder surgeons interpret and act upon new evidence, contributing to unwarranted variation in care. When it comes to treatment recommendations, what surgeons believe at the outset may matter as much or more than the data itself. Implementing targeted strategies such as foundational principles based in behavioral ethics, evidence-based decision and debiasing aids, structured peer review, and routine performance feedback may help align treatment decisions more closely with a patient's values based on the best available evidence. The use of rTSA-favoring evidence in this simulation is solely for illustrative purposes and should not be interpreted as an endorsement of increased rTSA use in clinical practice.

Background
Postage stamp fractures are a rare but considerable complication after arthroscopic Bankart repair. Previous literature has implicated various patient- and technique-specific factors, but analyses often lacked comparison to the broader operative sample. The purpose of this study is to systematically review the literature on postage stamp fracture after arthroscopic Bankart repair, evaluate patient- and anchor-specific risk factors, and contextualize findings within the full operative sample.
Methods
A systematic review was conducted to identify studies reporting postage stamp fractures following arthroscopic Bankart repair using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Patient demographics, anchor characteristics, and surgical outcomes were extracted. Risk factor associations were evaluated descriptively, with emphasis on whether reported associations held true across the full sample of surgical cases in each study.
Results
A systematic search yielded 2,349 articles; after duplicate removal and screening, 7 studies met inclusion criteria (2 comparative, 5 noncomparative). Studies included a total of 1,264 patients aged 10-61, with fracture incidence in larger cohorts ranging from 1.58% to 5%. Most patients with fractures participated in sports, particularly contact or high-risk activities. Although male patients made up the majority of fracture cases, this reflected the underlying demographic of operative patients. Patients with fractures were often the same age or older than the overall sample. Anchor number, diameter, type, and material were variably reported. Average anchor count was not consistently higher in patients with fractures, and no study found a significant association between anchor quantity and fracture risk. Absorbable anchors were implicated in a higher proportion of fracture cases. Osteolysis was common among patients with fractures. Insertion angle and suture type (knotted vs. knotless) were inconsistently reported and not clearly linked to fracture incidence.
Conclusion
Male sex and younger age, previously identified as risk factors, were not associated with postage stamp fractures when contextualized within the full operative sample. Presence of osteolysis and athletic participation was consistently associated with postage stamp fracture and may represent meaningful risk factors. Contrary to earlier reports, higher anchor quantity was not associated with increased postage stamp fracture risk; instead, lower anchor counts may be linked to instability, which itself may predispose to postage stamp fracture. Use of absorbable anchors emerged as a potential contributor to fracture risk that warrants further research.

The present study primarily aimed to investigate whether preoperative pain associated with rotator cuff tears correlates with the severity of synovitis in the rotator interval (RI) on arthroscopic findings retrospectively.
Methods
Between July 2017 and December 2022, 131 shoulders with arthroscopic rotator cuff repair were retrospectively investigated. The pain domain of the preoperative Constant Score and Shoulder36 were used to assess preoperative pain. Two examiners confirmed the degree of synovitis of RI in the arthroscopic findings.
Results
The mean patient age was 68.9 years. Synovitis in the RI was found in 118 shoulders (94%) assessed by arthroscopy. The pain domain of the Constant Score significantly correlated with synovitis in the RI assessed by arthroscopic findings (P < .01), but the size and the number of rotator cuff tears did not.
Conclusion
The preoperative pain associated with rotator cuff tears significantly correlated with synovitis severity in the RI assessed by AS findings, highlighting the role of synovitis as a potential contributor to pain in patients with rotator cuff tears.

Background
Glenohumeral rotational motion should be interpreted within the context of relative humeral retrotorsion (rHRT). To date, no study has investigated shoulder rotational motion within the context of rHRT in a medial ulnar collateral ligament (MUCL)–injured population. Therefore, the purpose of this study was to determine if there were differences in HRT-corrected rotational motion between MUCL-injured and uninjured college baseball players.
Methods
Thirty-five baseball players diagnosed with an MUCL injury were matched with 35 uninjured controls. Glenohumeral external rotation (GER) and internal rotation (GIR), as well as anatomic HRT, were collected on both arms. Data reduction was performed for all objective rotational motions and anatomic HRT, which was used to quantify rHRT. rHRT was then used to calculate HRT-corrected GER and HRT-corrected GIR. Outcomes were compared between groups using multivariate analysis of covariance, controlling for baseline cohort differences.
Results
Results indicated no significant multivariate effects of cohort, body mass index, or level of competition on HRT-corrected GER or GIR (all Pillai's Trace P > .05, partial η2 ≤ 0.019). Adjusted estimated marginal means for HRT-corrected GER were –9.99° (standard error [SE] = 2.51) for the MUCL cohort and –5.45° (SE = 2.51) for the uninjured cohort; for HRT-corrected GIR, they were 5.01° (SE = 2.46) and 2.21° (SE = 2.46), respectively.
Conclusion
HRT-corrected GER deficits are more prevalent than HRT-corrected GIR deficits in both cohorts. These findings continue to highlight the importance of accounting for osseous adaptations in range of motion measurements, as GIR deficit is not as common as previously thought.
