PURPOSE: This study aimed to determine if bipolar lesions (BL) are associated with inferior clinical outcome following articular cartilage regeneration (CR) compared to unipolar lesions (UL). METHODS: A registry-based study including patients undergoing isolated CR for focal knee cartilage lesions was performed. Lesions were considered UL or BL depending on the opposing cartilage. Propensity score matching was applied to eliminate potential confounders. Two groups comprising 119 patients with similar baseline characteristics were matched...

PURPOSE: To report the results of the arthroscopic superior capsule reconstruction (ASCR) technique with a combined fascia lata autograft and synthetic scaffold patch graft for irreparable massive rotator cuff tears (RCTs).

PURPOSE: To evaluate the cost-effectiveness of three isolated meniscal repair (IMR) treatment strategies: platelet-rich plasma (PRP)-augmented IMR, IMR with a marrow venting procedure (MVP), and IMR without biologic augmentation. METHODS: A Markov model was developed to evaluate the baseline case: a young adult patient meeting the indications for IMR. Health utility values, failure rates, and transition probabilities were derived from the published literature. Costs were determined based on the typical patient undergoing IMR at an outpatient surgery center...

PURPOSE: The purpose of this study was to investigate the correlation between non-traumatic medial meniscus posterior root tear(MMPRT) and bone morphology of the knee with a particular emphasis on MMPR impingement. METHODS: Magnetic Resonance imaging (MRI) findings were examined between January 2018 and December 2020. MRI findings of patients with traumatic MMPRT, kellgren lawrence stage 3-4 arthropathy on x-rays, single or multiple ligament injuries and/or those who underwent treatment for these diseases, and surgery in and around the knee were excluded from the study...

PURPOSE: The purpose of this study was to compare early patient reported outcomes after staged versus combined hip arthroscopy and periacetabular osteotomy for hip dysplasia. METHODS: A prospective database was retrospectively reviewed to identify patients that underwent combined or staged hip arthroscopy and PAO from 2012-2020. Patients were excluded if they were >40 years of age, had prior ipsilateral hip surgery, or did not have at least 12-24 month postoperative PRO data...

PURPOSE: To systematically review the current literature regarding the indications, techniques, and outcomes following two-stage revision anterior cruciate ligament reconstruction (ACLR). METHODS: A literature search was performed using SCOPUS, PubMed, Medline, and the Cochrane Central Register for Controlled Trials according to the 2020 Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) statement. Inclusion criteria was limited to level I-IV human studies reporting on indications, surgical techniques, imaging, and/or clinical outcomes of two-stage revision ACLR...

PURPOSE: To systematically review and report the mid- to long-term patient reported outcomes (PROs) following hip labral reconstruction. METHODS: A literature search of the Pubmed, Embase, and Cochrane Library databases was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for clinical studies reporting mid- to long-term PROs at minimum five year follow-up following arthroscopic hip labral reconstruction. A quality assessment was performed using the Methodological Index of Non-Randomized Studies (MINORS) grading system...

PURPOSE: To identify the factors associated with anterior cruciate ligament return to sport after injury (ACL-RSI) scores in patients awaiting ACL reconstruction (ACLR). METHODS: This was a retrospective cross-sectional observational study conducted at a single clinical center. We recruited patients scheduled for primary ACLR, aged 16-45 years, and with modified Tegner activity scale scores ≥5 before ACL injury. The main outcome was psychological readiness to return to sport (RTS), as measured using the ACL-RSI scale...

PURPOSE: 1. Evaluate how the meniscotibial ligament (MTL) affects meniscal extrusion (ME) +/- concomitant posterior medial meniscal root (PMMR) tears. 2. Describe how ME varied along length of meniscus. METHODS: ME was measured using ultrasonography in 10 human cadaveric knees in conditions: (1) control, either (2a) isolated MTL sectioning, or (2b) isolated PMMR tear, (3) combined PMMR + MTL sectioning, and (4) PMMR repair. Measurements were obtained 1 cm anterior to the MCL (anterior), over the MCL (middle), and 1 cm posterior to the MCL (posterior) +/- 1000N axial loads in 0° and 30° flexion...

METHODS: We conducted a retrospective comparative study of hip arthroscopy patients with minimum 2-year follow-up...

PURPOSE: To compare post-operative complication rates between patients who underwent medial patellofemoral ligament reconstruction (MPFLR) versus MPFLR with tibial tubercle osteotomy (MPFLR/TTO) in a large-scale study. A secondary goal was to investigate demographic associations with outcomes. METHODS: Patients who underwent MPFLR (n = 3,480) or MPFLR/TTO (n = 615) for patellar instability were identified in the PearlDiver database. Rates of surgery for infection, procedures for knee stiffness, patellar fracture, and revision MPFLR within two years post-operatively were compared using multivariable logistic regression...

PURPOSE: The purpose of the systematic review was to determine, in patients undergoing joint preservation procedures, whether the FJS compares favorably to legacy measures. METHODS: Medical databases (Pubmed, MEDLINE, EMBASE) were queried for publications with the terms "Forgotten Joint Score" "Hip" "Knee" "Arthroscopy" and "ACL." 14 studies met the inclusion criteria. Methodological quality was assessed through COSMIN checklists and psychometric data was evaluated for ceiling/floor effects, convergent validity, internal consistency, reliability, responsiveness, measurement invariance, and measurement error by two fellowship trained orthopedic surgeons (BDK; WTH)...

PURPOSE: This study aimed to investigate the prevalence of a contralateral rotator cuff tear (RCT) in patients with a symptomatic RCT requiring repair and to determine whether findings from magnetic resonance imaging (MRI) of the affected shoulder can predict the presence of a contralateral tear. METHODS: Patients with atraumatic RCTs who had undergone arthroscopic repair between March 2019 and February 2021 were reviewed in this study. Magnetic resonance imaging (MRI) of both shoulder joints was performed to evaluate the bilaterality of RCT...
