Articular cartilage injuries are common and have been found in approximately 60% of knees 1,2 and 5% of shoulders 3 undergoing arthroscopy. While many of these are incidental findings, the remainder are often symptomatic and debilitating and present a unique challenge secondary to the poor regenerative capacity of the native tissue. Cartilage repair(More)
PURPOSE There is currently limited information available in the orthopaedic surgery literature regarding the appropriate management of symptomatic partial-thickness rotator cuff tears. METHODS A systematic search was performed in PubMed, EMBASE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and the Cochrane Central Register of(More)
PURPOSE The purpose of this study was to assess the biomechanical performance of the long head of the biceps tenodesis with an interference screw with respect to screw depth. METHODS Twenty-one human cadaveric shoulders were randomized into 3 treatment groups (7 each): interference screw placed flush to the humeral cortex, 50% proud, or fully recessed.(More)
Indications for the use of osteochondral allografts for orthopaedic surgical applications are increasing with improved surgical techniques and advancing experience. Modern tissue banks have developed harvesting, processing, and storage methods that ensure an adequate, safe supply of grafts. Continued research is necessary to find a technique that(More)
PURPOSE The purpose of this study was to report the clinical outcomes of autologous chondrocyte implantation (ACI) procedures performed by a single orthopedic surgeon at a minimum of 7 years follow-up. METHODS A retrospective review of prospectively collected data was performed on 29 patients who underwent ACI of the knee between the years of 1998 and(More)
The tibial tubercle (interchangeable with tuberosity) is the most distal anchor of the extensor mechanism and can serve as a tool in altering patellofemoral (PF) mechanics. Known collectively as distal realignment procedures, osteotomies of the tibial tubercle are a useful method to treat a variety of PF conditions by allowing coronal, axial, and sagittal(More)
BACKGROUND Preventing anatomic failure after rotator cuff repair (RCR) remains a challenge. Augmentation with a surgical mesh may permanently reinforce the repair and decrease failure rates. The purpose of this study is to assess the postoperative outcomes of open RCR augmented with a novel reticulated polycarbonate polyurethane patch. MATERIALS AND(More)

Articular cartilage defects of the knee present diagnostic and treatment challenges for orthopaedic surgeons. As new data and technologies become available, treatment algorithms are continually being refined. It is important to examine treatment recommendations from the current literature and understand surgical techniques for articular cartilage repair.
