What is minimally invasive knee replacement surgery?
The usual approach to knee replacement involves splitting the quadriceps muscle in the middle and retracting the kneecap to one side. Minimally invasive knee replacement is done using an incision that splits a smaller portion of the muscle. This permits a faster recovery, and is generally done for slim patients with good flexibility in the knee. It is difficult to perform this kind of surgery in obese patients and in those who have stiff knees. The procedure requires special instruments. Computer navigation is used to improve the accuracy of the procedure.
