The exposure allows for meticulous soft tissue handling, reducing the risk of iatrogenic injury to the saphenous nerve. The distal femur is then visualized, allowing for plate application or intramedullary nailing depending on the fracture pattern.
Essential Steps for Mastering the Medial Approach to Distal Femur
The incision typically begins just distal to the medial joint line, following the medial parapatellar or periarticular plane. Range of motion exercises are initiated early to prevent arthrofibrosis, while quadriceps activation is prioritized to support the knee once protected weight-bearing advances.
Key landmarks include the saphenous nerve and vein, which run just beneath the subcutaneous tissue, and the gracilis tendon, which serves as a critical superficial guide to the deeper structures. The plane between the sartorius, gracilis, and semitendinosus muscles provides access to the distal femur while preserving the vascular supply entering from the medial femoral condyle.

Anatomical Landmarks and Surgical Plane Success with this approach hinges on a precise understanding of the underlying anatomy. This pathway, defined by its location along the inner aspect of the knee, allows surgeons to address comminuted supracondylar fractures, perform high tibial osteotomies, and execute precise soft tissue balancing with minimal disruption to the extensor mechanism.
