Indications and Clinical Applications While the lateral approach is often favored for simple total knee arthroplasty, the medial corridor is indispensable for specific high-demand scenarios. Sequential muscle splitting, rather than cutting, of the vastomedialis facilitates exposure while maintaining vascular integrity.
Protecting the Saphenous Nerve During Medial Distal Femur Surgery
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. Surgeons must also be vigilant regarding the possibility of damaging the popliteal vessels when dissecting posteriorly.
It affords direct visualization of the posterior condylar pillars, which is critical for restoring the joint congruity and mechanical axis. Orthopedic surgeons also utilize this approach for high tibial osteotomy correction, particularly when precise medial compartment unloading is required, and for accessing the distal femur during vascularized bone graft procedures.
Protecting the Saphenous Nerve During Medial Distal Femur Surgery
The incision typically begins just distal to the medial joint line, following the medial parapatellar or periarticular plane. 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.
