A simplified approach to the tibial attachment of the posterior cruciate ligament.

The standard approach through the popliteal fossa to the tibial attachment of the posterior cruciate ligament (PCL) can be time-consuming and is regarded as hazardous. The simplified approach does not transect or expose neurovascular structures as in other procedures. With dissection on the medial border of the medial head of the gastrocnemius and by lateral retraction, the posterior capsule is safely exposed. The approach is ideal for internal fixation of an avulsed tibial attachment of the PCL.

Late-onset tibia vara.

Fifteen children with late-onset tibia vara were studied. There were seven unilateral and eight bilateral cases. Eleven children were male, four were female and 13 were black; 14 were obese. All had a history of gradually progressive genu varus (average onset 11 years); 12 had preoperative knee pain. The average age at surgery was 12 years, with a preoperative tibiofemoral angle of 14 degree varus. The average follow-up was 4 years 4 months. The average tibiofemoral angle at follow-up was 0 degrees. There were 15 good, two fair, and six poor final results.
