Effect of lateral release on patellar motion in chondromalacia. An MRI study of 11 knees.
Preoperatively and postoperatively, patellar motion in 11 knees with chondromalacia was analyzed by MRI at 0 degrees, 10 degrees, 20 degrees, and 30 degrees of knee flexion. The preoperative patellar position clearly deviated from normal at 0 degrees-10 degrees of knee flexion. The lateral release operation corrected this deviation.
