BACKGROUND Techniques for reconstruction of the dislocated acromioclavicular (AC) joint abound. Most, however, do not address the injured AC ligaments and capsule. Evidence exists supporting the horizontal stabilizing effect of these ligaments on the AC joint. A novel AC and coracoclavicular (CC) reconstruction technique with an intramedullary free-tissue(More)
BACKGROUND It has been suggested that patellofemoral contact pressures and contact forces may be altered secondary to an opening wedge high tibial osteotomy, yet few data are available that quantify the effect of varying degrees of medial opening wedge osteotomy on the patellofemoral joint contact characteristics. HYPOTHESIS Opening wedge medial proximal(More)
BACKGROUND Several different surgical techniques have been described to address the coracoclavicular (CC) ligaments in acromioclavicular (AC) joint injuries. However, very few techniques focus on reconstructing the AC ligaments, despite its importance in providing stability. The purpose of our study was to compare the biomechanical properties of two(More)
BACKGROUND The active compression test has been described to detect superior labrum anterior and posterior (SLAP) lesions. Some have speculated that contact between the lesser tuberosity and the superior glenoid in the testing position causes a positive test. This study evaluated the location of peak glenohumeral contact pressures during a simulated active(More)
INTRODUCTION Proximal ulna fractures can cause a significant loss of forearm rotation, elbow stiffness, and disability. The objective of this study was to quantify the loss of forearm rotation after simulated varus and valgus malunions of the proximal ulna. METHODS Eight cadaveric upper extremities were used to quantify loss of forearm rotation after(More)
