BACKGROUND: Little is known on how meniscal morphology develops during skeletal growth and maturation and its subsequent relationship with the corresponding bony anatomy. HYPOTHESES: (1) Meniscal dimensions and morphology would change by age during skeletal growth and maturation in different ways in boys compared with girls. (2) Morphological features of the medial and lateral menisci would correlate to medial and lateral femoral condyle curvatures. STUDY DESIGN: Cross-sectional study; Level of evidence, 3...

OBJECTIVE: To assess the effect of aligning patients' preferences with specific rehabilitation delivery modes on rehabilitation outcomes. DESIGN: A secondary analysis of a randomized controlled trial (RCT). METHODS: The study cohort comprised 208 patients referred for physiotherapy rehabilitation after non-surgical or surgical interventions for rotator cuff injury, shoulder impingement, or acromioclavicular osteoarthritis. Participants were randomly assigned to one of three rehabilitation modalities: 1) group-based exercise, 2) individual exercise, or 3) home exercise...

OBJECTIVE: To compare the effects of personalized supervised group-based programs (group physical therapy programs) to usual one-on-one physical therapy care (usual physical therapy care) on disability for military personnel suffering from low back pain, rotator cuff-related shoulder pain, patellofemoral pain syndrome or lateral ankle sprain. Secondary outcomes were pain severity, pain-related fear, health-related quality of life and patients' satisfaction with their condition and care. DESIGN: Non-inferiority pragmatic randomized clinical trial...

BACKGROUND: Changes in knee loading have been reported after meniscectomy. Knee loading has previously been assessed during jogging and treadmill running rather than overground running, which could give altered results. PURPOSE/HYPOTHESIS: The purpose of this study was to evaluate knee function during overground running and walking after meniscectomy. It was hypothesized that the affected limb would demonstrate higher external knee adduction moment, lower knee flexion moment (KFM), and lower knee rotation moment (KRM) compared with the contralateral limb and with healthy individuals...

BACKGROUND: Improving our understanding of the situations and biomechanics that result in an anterior cruciate ligament (ACL) injury in basketball players may support the design of more effective programs to mitigate the risk of injury. PURPOSE: To (1) describe the mechanisms, situational patterns, and gross biomechanics (kinematics) of ACL injuries in professional basketball matches using video analysis and (2) document the distribution of ACL injuries according to player position, phase of the match, and location on the court...

BACKGROUND: Various short-form versions of the Knee injury and Osteoarthritis Outcome Score (KOOS) have been developed in an attempt to minimize responder burden. However, the responsiveness of these short-form measures in patients who have undergone anterior cruciate ligament (ACL) reconstruction has not been compared at midterm follow-up. PURPOSE: To determine the responsiveness of 3 short-form versions of the KOOS (KOOS-12, KOOS-Global, and KOOS-ACL) in patients who have undergone ACL reconstruction...

BACKGROUND: Medial ulnar collateral ligament (mUCL) injury can cause significant pain and alter throwing mechanics. Common autograft options for mUCL reconstruction (UCLR) include the palmaris longus (PL) and hamstring tendons. Allograft use may reduce donor site morbidity and decrease function related to PL autografts. PURPOSE: To compare varus stability and load to failure between a novel allograft for UCLR-knee medial collateral ligament (kMCL)-and a PL autograft in human donor elbow specimens...

PURPOSE: This study aimed to assess the validity and informational value of TikTok content about epicondylitis. The hypothesis tested herein was that TikTok video content would not provide adequate and valid information. METHODS: The term "epicondylitis" was used as a keyword to comprehensively search for TikTok videos, and the first 100 videos that were retrieved were subsequently included for analysis. The duration, number of likes, number of shares and number of views were recorded for each video...

BACKGROUND: Recent studies have reported conflicting results as to whether isolated medial patellofemoral ligament reconstruction (MPFLr) leads to decreased patellar height. PURPOSE: To investigate if patellar stabilization surgery not intended to address patella alta influences patellar height. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A multicenter retrospective chart review was conducted, and patients who underwent MPFLr, medializing tibial tuberosity osteotomy (TTO), and/or trochleoplasty between 2016 and 2020 were included...

BACKGROUND: The rate of concomitant meniscal procedures performed in conjunction with anterior cruciate ligament (ACL) reconstruction is increasing. Few studies have examined these procedures in high-risk pediatric cohorts. HYPOTHESES: That (1) the rates of meniscal repair compared with meniscectomy would increase throughout the study period and (2) patient-related factors would be able to predict the type of meniscal operation, which would differ according to age...

BACKGROUND: In young athletes with anterior cruciate ligament (ACL) injury, increased times from injury to magnetic resonance imaging (MRI) and injury to surgery can lead to the accrual of new injuries over time. PURPOSE: To determine the patient characteristics associated with differences in timing between injury, MRI, and surgery in young athletes with ACL tears. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: We reviewed the electronic medical records of patients aged 13 to 25 years who underwent isolated primary ACL reconstruction between January 2017 and June 2020 at a single orthopaedic surgery department...

BACKGROUND: Understanding the challenges and potential of telehealth visits (THVs) in a large population can inform future practice and policy discussion for pediatric orthopaedic and sports medicine (OSM) care. We comprehensively assess telehealth challenges and potential in a large pediatric OSM population based on access, visit completion, patient satisfaction, and technological challenges. METHODS: Demographics, address, insurance, visit information, patient feedback, experience with video visits, and technical challenges of all 2019 to 2020 visits at our hospital were assessed (3,278,006 visits)...

BACKGROUND: Platelet-rich plasma (PRP) is an effective treatment for knee osteoarthritis (OA). Microfragmented adipose tissue (MFAT) is another orthobiologic that holds promise, but data supporting its use are limited. Previous studies showed that MFAT created using the Lipogems device was equivalent to PRP created via noncommercial laboratory-based processes. PURPOSE: To perform a comparison of commercially available MFAT and PRP systems for treatment of knee OA...

BACKGROUND: Detailed knowledge of the anatomic course of the common peroneal nerve (CPN) is crucial for the surgical treatment of the posterolateral corner (PLC) of the knee. PURPOSE: To investigate the relationship of the CPN to the PLC of the knee at different flexion angles. STUDY DESIGN: Descriptive laboratory study. METHODS: Ten healthy volunteers were recruited to undergo magnetic resonance imaging (MRI) of the knee joint at knee flexion angles of 0°, 30°, 60°, 90°, and 120°...

BACKGROUND: Assessment of 3-dimensional (3D) femoral head coverage is critical in evaluating, preoperative planning, and treating hip dysplasia. PURPOSE: To (1) propose a mathematical model to establish 3D femoral head coverage using conventional computed tomography (CT), (2) determine the correlation of 2D parameters with 3D coverage, and (3) characterize the patterns of dysplasia based on 3D morphology. STUDY DESIGN: Cross-sectional study; Level of evidence, 3...

BACKGROUND: Given the variability of the questions asked, the Patient-Reported Outcomes Measurement Information System (PROMIS) upper extremity (UE) computer adaptive test (CAT) Version 2.0 item bank aids in the evaluation of rotator cuff repair (RCR) rehabilitation by determining when recovery milestones are possible based on the quality of patient responses at certain time points. PURPOSE: To assess the time point at which patients with RCR were able to achieve specific functional milestones, determined as positive responses to the 5 most frequently asked items on the PROMIS UE CAT Version 2...

BACKGROUND: Ulnar collateral ligament (UCL) reconstruction has been the standard surgical intervention for elite male athletes with UCL insufficiency. Recently, UCL repair and augmentation with an internal brace has been increasingly performed. PURPOSE: To evaluate the clinical and functional outcomes as well as return-to-sport rate after UCL repair in female athletes. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Included were 15 female athletes (mean age, 16...

BACKGROUND: Soft tissue plays an important role in stabilizing the hinge point for osteotomy around the knee. However, insufficient data are available on the anatomic features of the soft tissue around the hinge position for lateral closing-wedge distal femoral osteotomy (LCWDFO). PURPOSE: To (1) anatomically analyze the soft tissue around the hinge position for LCWDFO, (2) histologically analyze the soft tissue based on the anatomic analysis results, and (3) radiologically define the appropriate hinge point to prevent unstable hinge fracture based on the results of the anatomic and histological analyses...

OBJECTIVE: To synthesize and present reference values for double-leg and single-leg jump tests in healthy athletes who play pivoting sports, and athletes with anterior cruciate ligament reconstruction (ACLR) who play pivoting sports.
