The purpose of this study was to demonstrate that specialized magnetic resonance imaging provides an accurate assessment of lesions of the articular cartilage of the knee. Arthroscopy was used as the comparative standard. Eighty-eight patients who had an average age of thirty-eight years were evaluated with magnetic resonance imaging and subsequent(More)
PURPOSE The purpose of this study was to objectively evaluate the anatomic and biomechanical outcomes of anterior cruciate ligament (ACL) reconstruction with transtibial versus anteromedial portal drilling of the femoral tunnel. METHODS Ten human cadaveric knees (5 matched pairs) without ligament injury or pre-existing arthritis underwent ACL(More)
BACKGROUND Arthroscopic treatment has evolved to become the primary surgical option in the management of anterior shoulder instability as studies show comparable outcomes between open and arthroscopic techniques. OBJECTIVE To evaluate prospectively the results of our institutional database for arthroscopic Bankart repairs at a minimum 2-year follow-up for(More)
HYPOTHESIS Acromioclavicular (AC) joint injuries vary in severity and damage to the AC and coracoclavicular (CC) ligaments. We hypothesized that transclavicular-transcoracoid drilling techniques, which allow for arthroscopic passage and fixation of tendon grafts in bone sockets to replace the insufficient conoid and trapezoid ligaments, cannot restore the(More)
BACKGROUND To our knowledge, there has been no prospective study on the results of arthroscopic repair of superior labrum-biceps anchor complex (SLAP) tears with use of modern techniques. The purpose of the present study was to prospectively evaluate the minimum two-year results for patients with type-II SLAP tears that were treated with arthroscopic suture(More)
PURPOSE To compare the clinical outcomes of patients undergoing all-arthroscopic versus mini-open rotator cuff repair. In addition, ultrasound was used to assess the integrity of the repair. METHODS A total of 38 patients who had undergone all-arthroscopic repair and 33 patients who had undergone mini-open repair with minimum 2-year follow-up were(More)
Fifty-seven consecutive patients (58 knees) with an acute, isolated, posterior cruciate ligament (PCL) injury were treated nonoperatively. Clinical, radiographic, and functional assessment was performed at a mean follow-up of 6.9 years (range 2 to 19.3 years) after the initial diagnosis. At the time of initial documentation of the injury, the posterior(More)
Injuries to the biceps and triceps tendons about the elbow are relatively infrequent. Typically, they are traumatic events that occur as a result of a forceful eccentric contraction. Early recognition of these injuries and prompt intervention are the cornerstones to a successful outcome. Acute anatomic repair of complete injuries offers predictably good(More)
PURPOSE To discuss a new technique for the surgical treatment of type II SLAP lesions as well as the evaluation of the technique's effectiveness with a minimum 2-year follow-up. TYPE OF STUDY Retrospective clinical follow-up study. METHODS We present a clinical follow-up of 31 patients who were treated arthroscopically for type II SLAP lesions using a(More)
A loss of motion after an operation on the shoulder often cannot be treated successfully with physical therapy or closed manipulation. Although open release techniques generally improve motion, they involve extensive dissection. We developed a technique of arthroscopic capsular release and applied it in eighteen patients who had postoperative stiffness of(More)
