The subvastus approach is a surgical technique for knee replacement that involves accessing the knee joint by splitting the vastus medialis muscle, rather than cutting through it.

Preparation
Before surgery, anaesthesia is administered to ensure the patient's comfort.

Muscle Preservation:
The vastus medialis muscle is partially split to access the knee joint, preserving muscle integrity.

Less Muscle Damage
Compared to traditional approaches that involve cutting through the muscle, the subvastus approach may result in less muscle damage and faster recovery.
