Approaches for MIO


The fascia lata is incised along the cranial border of the biceps femoris muscle. The biceps femoris is retracted caudally. The intermuscular septum attached to the femur and located between the vastus lateralis muscle and the biceps femoris muscle is incised to allow adequate muscle retraction. A branch of the distal caudal femoral artery may have to be ligated or cauterized and transected as it enters the vastus lateralis muscle distally.
Retraction of the vastus lateralis muscle cranially and the biceps femoris muscle caudally exposes the distal femoral metaphysis.
