Valgus osteotomy with anterior cruciate ligament laxity.

Some patients with medial joint degeneration post-medial meniscectomy also have a significant anterior cruciate ligament (ACL) instability. Ten patients were treated by a combined high tibial valgus osteotomy with ACL reconstruction. All patients had relief of instability and decreased pain, although only one returned to full activity. The operation is recommended as a salvage procedure for an ACL deficient knee with instability and medial joint degeneration.
