High tibial osteotomy: indications, techniques, and postoperative management.

High tibial osteotomy is a safe and effective treatment for medial compartment arthrosis of the knee accompanied by varus alignment. This procedure has seen increasing use as an adjunct to cartilage restoration procedures, such as autologous chondrocyte and meniscal allograft transplantation, when angular deformity exists. The overall goals of high tibial osteotomy can be accomplished by several different techniques. The main indications for high tibial osteotomy are as a primary treatment for varus gonarthrosis and in conjunction with cartilage restoration procedures, such as autologous chondrocyte implantation or microfracture, where success rates are enhanced by correcting the varus deformity.
