Twenty-three percent of the knees actually had improved flexion, whereas 6\% were unchanged. On the average, patients' flexion decreased 14.4 degrees from a preoperative PKF of 131.5 degrees to 117.1 degrees postoperatively (p < 0.0001). Only 11.5\% of patients had PKF < 90 degrees at most recent follow-up, however; only 1.9\% had PKF < 60 degrees. Thirteen percent of ambulators eventually required a rectus femoris transfer to correct "stiff-legged gait."
