MIS Joint Replacement offers important advantages, requiring smaller incisions and potentially causing less trauma, shorter hospital stay, faster recovery and less scarring than traditional techniques.
Minimally invasive knee replacement is performed through a shorter incision—typically 4 to 6 inches versus 8 to 10 inches for traditional knee replacement. A smaller incision allows for less tissue disturbance.
In addition to a shorter incision, the technique used to open the knee is less invasive. In general, techniques used in minimally invasive knee replacement are “quadriceps sparing,” meaning they avoid trauma to the quadriceps tendon and muscles in the front of the thigh. Other minimally invasive techniques called “midvastus” and “subvastus” make small incisions in the muscle but are also less invasive than traditional knee replacement. Because the techniques used to expose the joint involve less disruption to the muscle, it may lead to less postoperative pain and reduced recovery time.
The hospital stay after minimally invasive surgery is similar in length to the stay after traditional knee replacement surgery. This ranges from outpatient (same day) surgery to a hospital stay of 1 to 4 days. Physical rehabilitation is a critical component of recovery. Your surgeon or a physical therapist will provide you with specific exercises to help increase your range of motion and restore your strength.
