Chronic anteromedial instability of the knee

This is a review of 26 patients with 2 or more years of knee pain or giving way or both in whom the most striking clinical finding was moderate or marked anteromedial instability. Of 27 knees, more than 15 responded favorably to a thigh-muscle-strengthening program. The Lenox Hill brace proved to be a useful adjunct in 9 patients.
