Lateral elbow reconstruction using a new fixation technique.

A radial collateral ligament reconstruction using interference fit screws instead of bone tunnels is described that uses a new screw design. A standard free graft is harvested. The isometric points on the lateral epicondylar ridge and ulna are identified. Fixation is completed after the isometricity of the insertion site is ensured and the graft is appropriately tensioned. A new interference-fit screw system is used (Arthrex, Naples, FL). There is much less trauma to the elbow, the fixation is stronger, and the scarring I believe will be minimized based on this technique.

Arthroscopic surgery for partial rotator cuff tears.

Rotator cuff pathology is one of the most common disorders of the shoulder. However, partial rotator cuff tears, treatment, and natural history are still in a state of flux. We believe that partial rotator cuff tears should be treated surgically when the rotator cuff is torn more than 50% of the thickness or when substantial thinning of the rotator cuff is identified arthroscopically. We believe that the technique described here addresses the need for increased blood supply in the rotator cuff and diminishes the chance for extension to a complete rotator cuff tear. The technique and postoperative rehabilitative regimen is described.

Modified osteochondral autograft implantation for full- thickness articular cartilage lesions.

Full-thickness articular cartilage defects have been difficult to treat in patients with nonarthritic knees. A procedure is described to treat articular cartilage full-thickness lesions. Graft sites are chosen after appropriate treatment of the base of a grade IV lesion. Articular cartilage and bone are replaced into the graft site, promoting mesenchymal stem cell growth and cartilaginous coverage of the defect. Pathology, postoperative protocol, and some postoperative arthroscopic illustrations are included. This technique is simple and is associated with minimal donor-site morbidity.
