Knee Osteotomy

This procedure is normally indicated for patients under 50 with valgus (knock-knee) or varus (bow leg) knee. It is done to postpone arthritis in a mal-alignment knee and if not done, can lead to a knee replacement. The procedure relieves pain on the affected side and is sometimes done in conjunction with knee ligament reconstruction procedures or meniscus implant.
