A biomechanical analysis of point of failure during lateral-row tensioning in transosseous-equivalent rotator cuff repair.

Purpose: The purpose of this study was to determine the maximum load and point of failure of the construct during tensioning of the lateral row of a transosseous-equivalent (TOE) rotator cuff repair.

Methods: In 6 fresh-frozen human shoulders, a TOE rotator cuff repair was performed, with 1 suture from each medial anchor passed through the tendon and tied in a horizontal mattress pattern. One of 2 limbs from each of 2 medial anchors was pulled laterally over the tendon.

Avoiding mismatch in allograft anterior cruciate ligament reconstruction: correlation between patient height and patellar tendon length.

Purpose: The purpose of this study was to evaluate whether a correlation exists between patient height and soft-tissue patellar tendon length.

Methods: Magnetic resonance imaging (1.5 T) was performed for knee pathology on 403 patients.

Evaluation and treatment of osteochondritis dissecans lesions of the knee.

Osteochondritis dissecans (OCD) is a condition affecting the subchondral bone of joints with secondary effects on articular cartilage that results in pain, effusions, loose-body formation, and mechanical symptoms. Left untreated, OCD can lead to the development of degenerative arthritis secondary to joint incongruity and abnormal wear patterns. This article discusses the etiology of knee OCD lesions, clinical presentation, proper evaluation, and treatment options.

Practical management of Lisfranc injuries in athletes.

Foot injuries are common in athletes. Injuries to the midfoot and, particularly, the Lisfranc joint are less common, but they have a high risk of ending the athlete's season or even career. Lisfranc injuries can be difficult to diagnose, and they often lead to a disastrous outcome when missed.

Lateral meniscus allograft biologic glenoid arthroplasty in total shoulder arthroplasty for young shoulders with degenerative joint disease.

To avoid potential polyethylene problems in younger shoulders with degenerative joint disease (DJD) requiring arthroplasty, lateral meniscus allograft (LMA) was used as a biologic resurfacing of the glenoid. We report preliminary, short-term results of this technique in a younger, higher-demand population. The shoulders of 20 men and 10 women, with an average age of 42 years (range, 18 to 52 years), underwent total shoulder arthroplasty with a LMA.
