An osteotomy refers to a surgical procedure in which the bone is cut and reshaped. Dr Marais may recommend a distal femoral osteotomy when it is necessary to repair a damaged joint, or adjust the length of a bone that does not line up with a joint properly.
Before undergoing distal femoral osteotomy, Dr Marais will perform a physical examination. He will do an alignment X-ray to ensure you are a suitable candidate for the procedure.
During a distal femoral osteotomy, the femur is cut thereby changing the alignment of the femur and also the lower limb. The cut bone is stabilised in its new position with a plate and scress after a bone graft is done onto the osteotomie area. The piece of bone that was removed from the iliac crest of the pelvis, is inserted into the osteotomy area. The result is that the body weight can carry more evenly re pressure on the diseased part of the knee and redistributing more evenly over the healthy part of the knee. This treatment is used for patients suffering from osteo-arthritis on one side of the knee. It is specifically done in the younger patient where a knee replacement is not indicated. In many cases the procedure can help to prolong the function of the knee and also delay a need for joint replacements.
After surgery Dr Marais will advise you on the best rehabilitation programme which will include physiotherapy and some lifestyle changes. You will be mobilised by using crutches until such time that the osteotomy has repaired by bony union.
