Pathological femoral anteversion is recognized as a cause of anterior knee pain. Derotational femoral osteotomy is a promising surgical intervention for anterior knee pain patients with excessive femoral anteversion. It is indicated in disabling anterior knee pain recalcitrant to conservative treatment with femoral anteversion >25° measured according to Murphy's method. However, robust evidence for a universal cutoff is lacking. It is contraindicated in patients with pathological femoral anteversion without clinical symptoms. Moreover, it is contraindicated for cosmetic reasons. This technical note describes our surgical technique of derotational osteotomy to correct pathological femoral anteversion. Femoral anteversion is problematic because it changes the direction of the quadriceps muscle. An intertrochanteric osteotomy allows a longer bone length for the thigh muscles to adjust to a new direction. The distal fragment of the femur is externally rotated until the correction desired in the preoperative planning is achieved. Good clinical outcomes and few complications have been reported with this surgical technique.

Allograft transplants are commonly used in orthopedics. Unlike other transplanted tissues, orthopedic tissue allografts are not human leukocyte antigen (HLA)-matched. The clinical impact of the immune response to allografts is poorly understood. Recent experience with allograft failures and reactions to anterior cruciate ligaments (ACL), medial patellofemoral ligament (MPFL), osteochondral, and meniscus transplants raises concern. This scoping review examines the literature on immunologic rejection of orthopedic tissue allograft using PubMed, Embase, Web of Science, and Scopus for studies describing immune rejection of orthopedic tissue allografts in humans and animals. Four reviewers independently screened titles/abstracts based on these criteria. Full texts were screened independently by two reviewers for inclusion. Variables of interest included the species, graft type, and graft treatment. Our literature search yielded 1625 articles, with 78 meeting the inclusion criteria. Of these studies, 30 (38.5%) were in humans, 16 (20.5%) in rats, and 11 (14.1%) in dogs. The remaining 21 studies were in a combination of rabbit, primate, mice, sheep, and cat subjects. The orthopedic tissues in these studies included 23 osteochondral (29.5%), 16 bone (20.5%), 13 cartilage (16.7%), 6 bone-tendon-bone (7.7%), and 12 tendon/ligaments (15.4%) with 8 (10.2%) of the studies specifically in menisci. Methods used to reduce immune response include freezing, irrigation, and immunosuppressant administration. Recorded histological evidence of immune response included cell apoptosis, type II collagen increase, interleukins (IL) secretion, and increased lymphocytes/plasma cells in the synovial fluid. The pathways proposed were mismatched in cell-surface proteins as many studies conducted major histocompatibility complex (MHC) class I matching, which reduced the immune response. Despite histological evidence, including HLA sensitization after transplant signaling an immune response, clinical significance was not observed. Recent clinical experience of increased magnetic resonance imaging (MRI) signal response to orthopedic allografts, along with patient symptoms, has raised questions about rejection. Clinical rejection reports are limited in this review. This immune response to orthopedic allografts must be considered, and additional studies are needed to explore the relationship between rejection and clinical outcomes. This scoping review indicates that there is a range of human and animal studies demonstrating various immunologic response presentations and severities with different orthopedic tissue allografts.
同种异体移植在骨科中应用广泛。与其他移植组织不同,骨科同种异体组织移植不是hla匹配的。同种异体移植物免疫反应的临床影响尚不清楚。最近的同种异体移植失败和对前交叉韧带、强韧带、骨软骨和半月板移植的反应引起了人们的关注。本综述通过PubMed、Embase、Web of Science和Scopus检索了描述人类和动物同种异体骨科组织移植免疫排斥反应的文献。四名审稿人根据这些标准独立筛选标题/摘要。全文由两位审稿人独立筛选纳入。感兴趣的变量包括种类、接枝类型和接枝处理。我们的文献检索得到1625篇文章,其中78篇符合纳入标准。在这些研究中,30项(38.5%)针对人类,16项(20.5%)针对大鼠,11项(14.1%)针对狗。其余21项研究的对象包括兔子、灵长类动物、老鼠、绵羊和猫。这些研究涉及的骨科组织包括23例骨软骨(29.5%)、16例骨(20.5%)、13例软骨(16.7%)、6例骨-肌腱-骨(7.7%)和12例肌腱/韧带(15.4%),其中8例(10.2%)的研究专门涉及半月板。用于减少免疫反应的方法包括冷冻、冲洗和免疫抑制剂。记录的免疫应答组织学证据包括细胞凋亡、II型胶原增加、IL分泌和滑膜液中淋巴细胞/浆细胞增加。由于许多研究进行了MHC I类匹配,因此提出的途径在细胞表面蛋白上不匹配,从而降低了免疫反应。尽管有组织学证据,包括移植后HLA致敏信号免疫反应,但没有观察到临床意义。最近的临床经验表明,对骨科同种异体移植的MRI信号反应增加,以及患者的症状,引起了对排斥反应的质疑。临床排斥反应报告在本综述中是有限的。必须考虑到这种对同种异体骨移植的免疫反应,并且需要进一步的研究来探索排斥反应与临床结果之间的关系。本综述指出,有一系列的人类和动物研究表明,不同的同种异体骨科组织移植有不同的免疫反应表现和严重程度。

Introduction/Objectives
To investigate whether the use of a three-dimensional (3D) printed model, compared to conventional imaging, resulted in better corrections of osseous deformities following femoral acetabular impingement syndrome (FAIS) hip arthroscopy by comparing radiographic outcomes.
Methods
A retrospective review of patients who underwent hip arthroscopy for FAIS between 2015 and 2019 was performed. Patients were sequentially allocated into the conventional or 3D model group. Radiographic plain films preoperatively and postoperatively assessed bony resection quality, measuring alpha angles and head-neck offset (HNO) ratios using 45° Dunn, frog-leg lateral, and anteroposterior views. Good resection was defined as an alpha angle <55° and poor resection as an alpha angle ≥55°.
Results
One hundred forty-eight patients were included (n = 86 in the conventional group and n = 62 in the 3D model group). Compared to conventional imaging, the 3D model group had statistically significantly lower postoperative alpha angles on 45° Dunn (p = 0.002) and frog-leg lateral views (p < 0.001). The change (preoperative to postoperative) in alpha angle was statistically significantly larger for the 3D model group, compared to conventional imaging, in 45° Dunn (p = 0.003) and frog-leg lateral views (p = 0.041). Compared to the conventional imaging group, the postoperative HNO ratio was statistically significantly higher in the 3D model group on 45° Dunn (p = 0.001) and frog-leg lateral views (p < 0.001) and change in HNO ratio was statistically significantly larger for the 3D model group in both 45° Dunn (p = 0.001) and frog-leg lateral views (p = 0.026). When considering the good and poor resections separately for all three radiographic views, the 3D model group showed a statistically significantly higher number of good resections than the conventional imaging group (p < 0.001).
Conclusions
Arthroscopic FAIS treatment shows adequate resection using conventional surgical planning. The use of a 3D model facilitated better cam resection and permitted more patients to return to those within normal radiological values as measured by alpha angles and HNO ratios.

Bony Bankart lesions are anterior glenoid rim fractures associated with anterior shoulder dislocation and can increase the risk of recurrent instability, particularly in cases of fragment resorption or malpositioned healing. Despite their clinical significance, few large-scale radiological studies have detailed the fragment characteristics, displacement patterns, and associated bipolar lesions. The objective of this study was to describe fragment morphology, displacement, and related shoulder parameters using computed tomography (CT) imaging.
Methods
This retrospective cohort study included 239 patients with isolated bony Bankart injuries identified via the Swedish Fracture Register between 2012 and 2019. All patients underwent CT imaging. Standardized linear measurement techniques were used to assess fragment size, displacement (inferior migration, diastasis, and step-off), Hill–Sachs lesion characteristics, glenoid version, and glenohumeral subluxation index.
Results
The mean bony Bankart fragment size was 6.5 mm, representing 21.8% of the glenoid width. While absolute fragment size was similar between sexes, it accounted for a significantly larger portion of the glenoid surface in females (p = 0.008). Fragment displacement parameters showed no sex-based differences. Hill–Sachs lesions were present in 61% of patients and were significantly larger in males (p = 0.007), though relative to humeral head diameter, differences were not significant. A consistent ratio of glenoid-to-humeral head diameter (∼66–67%) was observed across sexes.
Conclusion
Bony Bankart lesions frequently involve more than 20% of the anterior glenoid, particularly in female patients due to anatomical size differences. CT-based linear measurements provide valuable data for analyzing clinically significant critical bone loss in cases of bony Bankart injuries. The consistent glenoid-to-humeral head diameter ratio may aid surgical planning in shoulder reconstructive procedures.

The Marx Activity Rating Scale (MARS) is a validated patient-reported outcome measure quantifying high-demand knee activity frequency in anterior cruciate ligament (ACL)–injured populations. The instrument consists of 4 domains: running, cutting, decelerating, and pivoting. This prospective validation study aimed to translate and cross-culturally adapt the MARS into Thai and evaluate its psychometric properties among ACL-injured patients.
Methods
Cross-cultural adaptation followed Beaton's established guidelines, including translation, synthesis, backward translation, expert committee review, and pretesting. Validation of the Thai version of the MARS used dual recall timeframes: MARS with a 1-year recall period (MARSyr) and MARS with a 1-month recall period (MARSmo). A total of 110 ACL-injured patients, aged 18–50 years with pre-injury Tegner Activity Scale (TAS) scores ≥4, completed questionnaires at the baseline and 2-week follow-up. Psychometric evaluation encompassed construct validity, internal consistency, test-retest reliability, measurement error, and floor/ceiling effects.
Results
Cross-cultural adaptation of the Thai version of the MARS was successfully completed. Construct validity of the instrument was demonstrated by correlations between the MARS and the TAS with corresponding timeframes (Spearman's correlation coefficient of 0.51–0.61). Internal consistency was excellent with Cronbach's α coefficients of 0.87 (MARSyr) and 0.93 (MARSmo). Test-retest reliability showed excellent intraclass correlation coefficients of 0.93 (MARSyr) and 0.94 (MARSmo). Notable floor effects (33.6% for MARSmo) and ceiling effects (26.4% for MARSyr) were observed.
Conclusion
The MARS was successfully cross-culturally adapted into the Thai version. It exhibits acceptable psychometric properties for quantifying physical activity in ACL-injured populations. Floor/ceiling effects necessitate complementary outcome measures for comprehensive functional assessment.

Objectives
The deep lateral femoral notch sign, observed in some anterior cruciate ligament (ACL) injuries, may result from valgus-compressive forces and anterior tibial translation. Since combined ACL and medial collateral ligament (MCL) injuries often involve high valgus torque, we hypothesized an association between MCL tears and the presence of a deep lateral femoral notch sign.
Methods
We conducted a retrospective cohort study of skeletally mature patients (≥14 years) who underwent primary ACL reconstruction (ACLR) and had preoperative MRIs within 3 weeks of injury. Patients were grouped by the presence of a deep lateral femoral notch sign (≥2 mm depth). Superficial and deep MCL tears were graded via MRI. Demographics and meniscus surgery data were collected. Univariable and multivariable analyses were used to identify factors associated with the deep lateral femoral notch sign (P < .050).
Results
Among 590 included patients, 104 (17.6%) had a deep lateral femoral notch sign. Intra- and inter-observer reliability for notch depth and MCL grading showed near-perfect agreement (κ > 0.8). Multivariable analysis identified superficial MCL tear, younger age, and medial posterior tibial bone bruise as independent predictors of a deep lateral femoral notch sign (P < .001 for all). When stratifying superficial MCL tears, 12.6% of grade 0/I cases and 34.6% of grade II/III cases had deep lateral femoral notch signs. The sign showed 34.6% sensitivity, 87.4% specificity, and an odds ratio of 3.68 (95% CI, 2.35–5.77) for predicting grade II/III superficial MCL tears.
Conclusion
In acute ACL injuries, the deep lateral femoral notch sign is associated with grade II/III superficial MCL tears, showing high specificity and a 3.7-fold increased risk. Its presence should prompt careful assessment of MCL-related instability to optimize patient outcomes.

Introduction/Objectives
Irreparable subscapularis tears can cause severe functional impairment and present significant clinical challenges. Current treatment options include tendon transfers (TTs), anterior capsular reconstruction, and reverse shoulder arthroplasty. Each approach has distinct biomechanical advantages and limitations, but there remains no consensus regarding the optimal treatment. This systematic review aimed to evaluate and compare clinical outcomes, failure rates, and complication profiles of surgical reconstruction techniques for irreparable subscapularis tears.
Methods
This systematic review followed PRISMA guidelines. A comprehensive search was conducted in Embase, OVID Medline, and Emcare databases. Eligible studies included adults with irreparable subscapularis tears treated with surgical reconstruction (e.g., tendon transfers, graft augmentation, or anterior capsular reconstruction) and reporting clinical outcomes. Methodological quality was assessed using the Methodological Index for Non-Randomized Studies (MINORS) score. A narrative synthesis was performed with descriptive statistics (frequencies, percentages, or weighted means with variability).
Results
Fourteen studies comprising 351 patients (355 shoulders) were included, with a mean age of 58.1 years (SD 9.5) and mean follow-up of 44.7 months (SD 54.4). Studied procedures included latissimus dorsi (LD) TT (6 studies, n = 164), pectoralis major (PM) TT (5 studies, n = 94), pectoralis minor (Pm) TT (1 study, n = 74), and anterior capsular reconstruction (ACR; 2 studies, n = 25). PM TT had the highest failure rate (13.0 %), followed by ACR (12.0 %), LD transfer (11.0 %), and Pm TT (1.4 %). Postoperative complications were most frequent after PM TT (12.8 %), while LD TT had a complication rate of 9.8 %. Patient-reported outcome measures improved across all groups, with the greatest Constant-Murley Score (CMS) improvement following LD TT (+33.0), the greatest Subjective Shoulder Value (SSV) improvement after PM TT (+38.6), and the largest Visual Analogue Scale (VAS) pain reduction following ACR (−5.0) and Pm transfer (−5.1).
Conclusions
Surgical reconstruction techniques for irreparable subscapularis tears provide improvements in pain and function, though failure and complication rates vary by procedure and appear worse with concomitant rotator cuff pathology. Further high-quality comparative studies are needed to refine patient selection and optimize surgical decision-making.
