*
IKDC subjective questionnaire is scored from 0 to 100 points with 100 points indicating no pain, symptoms, or lack of function.
†
IKDC pain frequency and severity are graded on a scale of 0 to 10, with 0 being “no pain” and frequency as “never” and 10 being “worst pain imaginable” and “constant” frequency.
‡
Quadriceps muscle strength was evaluated with isokinetic testing at 180°/sec.
