Anterior cruciate ligament reconstruction using part of the patellar tendon as a free graft

Abstract

We have reviewed 40 patients after replacement of a ruptured anterior cruciate ligament with a free graft of the medial third of the patellar tendon, combining this in 17 of the cases with a MacIntosh extra-articular tenodesis. The average age of the patients at operation was 25.4 years; instability of the knee had been present for 1.5 to 9 years, and the mean follow-up was 2.9 years. The results, assessed on subjective stability, were good in 29 patients, over half being able to return to their original sport, and fair in eight. The technique of operation for free patellar tendon grafting is described in detail and the indications for this and for an additional MacIntosh tenodesis are discussed.
