This paper discusses function changes during an accelerated rehabilitation program at 6, 10, and 52 weeks postsurgery for a college athlete following anterior cruciate ligament reconstruction/meniscectomy of the left knee. The effects of combined pulsed electromagnetic field (PEMF) and neuromuscular electrical stimulation (NMES) on knee extensor torque, thigh girth, and pain level are presented. PEMF-NMES decreased stimulation pain by 76%. Knee extensor isometric torque increased by 23%, and thigh girth decreased less than 5% at 6 weeks. Knee extensor isokinetic torque was 13% and 3% deficient at 90°/s and 240°/s, and standing single-leg broad jump distance was 19% deficient at 10 weeks. Knee extensor isokinetic torque was 1% and 1.5% greater at 90°/s and 240°/s, and standing single-leg broad jump distance was 11% deficient at 52 weeks. Knee anterior laxity was 2 mm at 10 weeks and 3 mm at 52 weeks. PEMF-NMES appears to comfortably enhance knee extensor torque gains and diminish thigh girth loss. Despite early return to practice, functional deficit remained and anterior laxity was increased at 52 weeks.
