We describe 129 patients with disabling instability of the knee due to deficiency of the anterior cruciate ligament. They were treated by replacement of the ligament with a Leeds-Keio prosthesis supplemented by an extra-articular MacIntosh lateral substitution reconstruction. After an average period of 71 months a satisfactory outcome was found in only 60% of knees. Nine had required revision because of recurrent instability and the pivot-shift sign had become positive in 40% of patients. In our opinion the long-term results are unsatisfactory when compared with those obtained using a graft from the medial third of the patellar tendon supplemented with a MacIntosh extra-articular tenodesis.
