Case: A snapping biceps femoris tendon, a rare etiology for symptomatic pain in the lateral aspect of the knee, has been reported infrequently. We report 2 cases of an acutely symptomatic unilateral snapping biceps femoris tendon with an intraoperatively intact anomalous insertion onto the tibia, which were treated with anatomic repositioning and "pie-crust" lengthening via a single suture anchor.
Conclusion: Anatomic repositioning and lengthening is a novel technique that successfully resolved the painful snapping and allowed full return to competitive sports by 6 months postoperatively, with maintenance of improvement at ≥14 months postoperatively.
Aim: The purpose of this study was to analyze the publication rate for abstracts presented at podium presentations from the American Shoulder and Elbow Surgeons (ASES) annual open and closed meetings from 2008 to 2012.
Materials And Methods: Abstracts accepted as podium presentations for the open and closed meetings from 2008 through 2012 were followed. A search was performed using Google Scholar and PubMed for all published manuscripts.
Alterations have been made over the years to the standard reverse total shoulder arthroplasty (RTSA) prosthetic components in an effort to decrease adverse events; this has led to the advent of a short humeral stem prosthesis. To the authors' knowledge, there are no reports describing the complication of a traumatic periprosthetic Wright and Cofield classification type A fracture with use of a short metaphyseal humeral stem component for RTSA. The authors describe a 49-year-old woman with this pathology who was treated with open reduction and internal fixation using a proximal humerus locking plate, unicortical and bicortical screw fixation, and a cerclage wire construct without the need to violate the shoulder joint or revise components.

Methods: Twenty-seven consecutive patients scheduled to undergo a primary ACL reconstruction were prospectively evaluated. Physical examination and magnetic resonance imaging findings were analyzed to exclude multiligamentous injury.
Purpose: To use 3-dimensional custom CAD technology to evaluate how knee flexion angle affects femoral tunnel length and distance to the posterior wall when using curved and straight guides for drilling through the anteromedial portal (AMP).
Methods: Six cadaveric knees were placed in an external fixator at various degrees of flexion (90°, 110°, 125°, and maximum 135° to 140°). Computed tomography scans were obtained at all flexion points for 3-dimensional point-cloud models.
Purpose: To systematically review the literature to identify all studies reporting outcomes of arthroscopically repaired isolated subscapularis tears, to (1) report outcomes across all repair techniques, (2) compare outcomes by arthroscopic technique, and (3) highlight the frequency and management of associated long head of biceps pathology, and the influence of these concomitant procedures on outcomes following arthroscopic subscapularis repair.
Methods: A systematic literature review was conducted using the MEDLINE, Embase, and Scopus databases with the following term: ("isolated repair" AND "arthroscopic subscapularis tear"). Only studies evaluating the techniques and outcomes of isolated subscapularis repair were included.
Purpose: To analyze the publication rate of poster and podium presentations at Arthroscopy Association of North America (AANA) annual meetings from 2008 to 2012.
Methods: An online search using PubMed and Google Scholar for all published manuscripts associated with abstracts presented from 2008 to 2012 AANA annual meetings was performed. Abstracts were classified by presentation type (poster vs podium), and the journal and publication date were recorded for all published abstracts.
Background: Long-term studies of posterior cruciate ligament (PCL) reconstruction suggest that normal stability is not restored in the majority of patients. The Achilles tendon allograft is frequently utilized, although recently, the quadriceps tendon has been introduced as an alternative option due to its size and high patellar bone density.
Purpose/hypothesis: The purpose of this study was to compare the biomechanical strength of PCL reconstructions using a quadriceps versus an Achilles allograft.
Purpose: To identify all reported cases of growth disturbances after anterior cruciate ligament (ACL) reconstruction in patients with open growth plates and analyze trends with respect to different surgical techniques, graft choices, and methods of fixation.
Methods: A systematic literature review was conducted using the MEDLINE, EMBASE, and SCOPUS databases with the following term: "((anterior cruciate ligament OR ACL) AND ((((immature) OR growth plates) OR physes) OR pediatric))." Only studies that evaluated ACL reconstruction in patients with open growth plates and reported angular malformations or limb length discrepancy were included.
