**7. Above knee amputation**

Above Knee Amputation (AK Amputation) is Removing the Three Fourth Of The Leg from the body by cutting through femoral muscle and bone. The optimum length of the residual bone is approximately 7.5 – 10cm proximal to the superior border of the patella. With a AK amputation the distal attachments of the femoral muscles are lost, in order to preserve their length and functions myodesis may be performed.
