Minimizing Pain & Protecting Quadriceps in Knee Surgery | CSOG
Key Highlights
- Resurgence of the Subvastus Approach: Popularized in the 1990s, the subvastus approach is regaining popularity in total knee replacement surgery due to its muscle-sparing design [00:09 Opens in a new window].
- Preserving Muscle and Tendon: The technique accesses the joint through the interval between the vastus medialis obliquus (VMO) muscle and the medial intermuscular septum, completely avoiding cutting through the quadriceps muscle or tendon [00:38 Opens in a new window].
- Comparison to Standard Technique: Unlike the traditional medial parapatellar approach—which cuts directly through the quadriceps tendon—the subvastus method uses a similar skin incision size and a smaller arthrotomy without transecting muscle tissue [00:45 Opens in a new window].
- Patient Benefits: Patients undergoing the subvastus approach generally experience faster recovery of quadriceps strength and less pain during the first few days following surgery, though both methods are ultimately effective [00:59 Opens in a new window].
