Mid-axial longitudinal approach

The saphenous nerve runs along the medial aspect of the distal femur. The infrapatellar branches of the saphenous nerve lie on the medial and inferior aspects of the patella and run across to the lateral side. Postoperatively, there is usually minor sensory loss to the lateral side of the scar, but significant saphenous nerve damage is avoidable. Occasionally, there may be postsurgical saphenous nerve neuroma formation which is rarely a significant problem.
