BACKGROUND Recent investigations have described the structural and functional behavior of the anterolateral ligament (ALL) of the knee through pull-apart and isolated sectioning studies. However, the secondary stabilizing role of the ALL in the setting of a complete anterior cruciate ligament (ACL) tear has not been fully defined for common simulated(More)
BACKGROUND An avulsion of the posterior root attachment of the lateral meniscus or a radial tear close to the root attachment can lead to degenerative knee arthritis. Although the biomechanical effects of comparable injuries involving the medial meniscus have been studied, we are aware of no such study involving the lateral meniscus. We hypothesized that in(More)
BACKGROUND The purpose of this study was to perform a systematic review and meta-analysis of all available level I randomized controlled trials comparing single-row with double-row repair to statistically compare clinical outcomes and imaging-diagnosed re-tear rates. METHODS A literature search was undertaken to identify all level I randomized controlled(More)
The use of total shoulder arthroplasty (TSA) to treat primary glenohumeral osteoarthritis (GHOA) is increasing. Factors influencing patient satisfaction after surgery have not been well documented. The aim of this study was to determine demographic, radiologic, and surgical, factors predictive for satisfaction after TSA for GHOA. Between 2005 and 2012, 95(More)
BACKGROUND Posterior medial meniscal root tears have been reported to extrude with the meniscus becoming adhered posteromedially along the posterior capsule. While anatomic repair has been reported to restore tibiofemoral contact mechanics, it is unknown whether nonanatomic positioning of a meniscal root repair to a posteromedial location would restore the(More)
BACKGROUND While the effects of concurrent meniscal resection and anterior cruciate ligament reconstruction (ACLR) are known to decrease patient outcomes and increase the rate of osteoarthritis over the long term, overall short-term patient functional outcomes in a large cohort of patients are not well known. PURPOSE/HYPOTHESIS The purpose of this study(More)
STUDY DESIGN A retrospective observational study. OBJECTIVE To assess clinical outcomes, perioperative complications, revision surgery rates, and recombinant human bone morphogenetic protein-2 (BMP-2)-related osteolysis, heterotopic bone, and unexplained postoperative radiculitis (BMPP) in a group of patients treated with BMP-2-augmented transforaminal(More)
BACKGROUND Elevated expectations before orthopaedic procedures appear to correlate with inferior preoperative subjective measures. The purpose of this study was to evaluate preoperative patient expectations before arthroscopic shoulder surgery and to correlate them with preoperative subjective measures and patients' reasons for seeking treatment. METHODS(More)
BACKGROUND The Latarjet procedure for the treatment of recurrent anterior shoulder instability is highly successful, but reasons for failure are often unclear. Measurements of the "glenoid track" have not previously been evaluated as potential predictors of postoperative stability. HYPOTHESIS There are clinical and anatomic characteristics, including the(More)
Quantitative MRI T2 mapping is a non-invasive imaging technique sensitive to biochemical changes, but no studies have evaluated T2 mapping in pathologic rotator cuff tendons. It was sought to evaluate the efficacy of T2 mapping in detecting differences in the supraspinatus tendon (SST) among patients with tendinosis, partial tears and minimally retracted(More)
