Subvastus Approach to Knee Replacement

Sometimes known as Minimally Invasive Total Knee Arthroplasty, the subvastus approach allows the surgeon to remove damaged bone and tissue and replace it with an implant. However, the surgeon does not cut through the quadriceps muscle and tendon. The knee surgery is completed by going under and around the quadriceps muscle.

Among the potential benefits of this technique are:

  • More rapid return of knee function and less pain medicationuse in the first week post-surgery
  • Decreased postoperative pain compared to conventional knee replacement
  • Smaller incision sites

Orthopedic surgeons will look at each patient individually to choose the best approach for the patient. Some pre-existing conditions may make the traditional knee replacement a better choice. For example, patients with severe deformity or stiffness in the joint may require the traditional approach for more exposure of the inflamed tissues.
