Anterior cruciate reconstruction combined with valgus upper tibial osteotomy: 12 years follow-up.

A retrospective review of 29 patients (30 knees) was carried out who had previously undergone a single-stage combined ACL reconstruction with valgus upper tibial osteotomy for chronic ACL rupture coupled with early medial tibio-femoral arthritis. Of the 30 knees, 19 (63%) had had a previous medial meniscectomy. Major complications occurred in two knees resulting in stiffness. At a mean of 12 years follow-up (6-16 years) only five knees (17%) had progressed one arthritis grade. Fourteen patients (47%) returned to intensive sports, and a further 11 (37%) played moderate sports. The mean difference in anterior tibial translation with the opposite normal knee was 3 mm at review. It was concluded that the combined operation has a low morbidity, controls anterior laxity, allows many patients to return to sports, and does not result in a rapid progression of osteoarthritis.
