Arthroscopic identification of the anterior cruciate ligament posterolateral bundle: the figure-of-four position.

Anatomic double-bundle reconstruction in anterior cruciate ligament (ACL) tears has been developed during the last few years. Although anteromedial (AM) bundle reconstruction is routinely performed, finding the femoral attachment of the posterolateral (PL) bundle remains a problem. We describe how a classic arthroscopic position, the figure-of-4 position, allows the PL bundle to be easily recognized.

Anatomic double bundle: a new concept in anterior cruciate ligament reconstruction using the quadriceps tendon.

Surgical procedures for double-bundle anterior cruciate ligament reconstruction, which currently use hamstring graft, have been described, but some concerns remain regarding graft fixation and the ability to obtain adequate bundle size. We report an original double-bundle anterior cruciate ligament reconstruction technique using a quadriceps tendon graft and a simplified outside-in femoral tunnel-drilling process. The graft consists of a patellar bone block with its attached tendon split into superior and inferior portions, which yields 2 bundles.

Rotator cuff tears in middle-aged tennis players: results of surgical treatment.

Background: Tennis players, like participants in other overhead sports, are vulnerable to rotator cuff tears. In players who continue to play into their middle-age years, the incidence of such injury increases.

Hypothesis: Surgical treatment of rotator cuff tears in middle-aged tennis players is largely successful in allowing return to tennis.

Results of arthroscopic treatment of posterosuperior glenoid impingement in tennis players.

Twenty-eight tennis players with symptomatic posterosuperior glenoid impingement limiting their participation underwent arthroscopic debridement of the supraspinatus tendon and glenoid lesions associated with this diagnosis after nonoperative treatment had failed. The dominant extremity was affected in all patients; the patients' average age was 26.9 years.
