Abstract

The results of 32 minimally invasive quadriceps-sparing (Q-S) total knee arthroplasties were compared with those of a matched group of 35 standard total knee arthroplasties. The patients were prospectively followed for a mean of 24 months (range, 18-28 months). The Q-S group was significantly quicker in regaining quadriceps strength and knee flexion and had less pain during the first 2 postoperative weeks. The Knee Society scores showed no significant difference at 6 weeks, 1 year, and last visit. There were 9 outliers in the Q-S group, none in the standard group. The tourniquet time was significantly longer in the Q-S group. Patients in the Q-S group were 100% satisfied about the incision. The Q-S technique showed better and faster recovery, but there were more outliers and bone injuries during surgery, and this coupled with length of tourniquet time were the major disadvantages in our early experience.
