Abstract

Purpose of the studyThe aim of this prospective study was to evaluate the objective postoperative laxity and functional results with a minimum follow-up of 10 years (mean 11,7 +/-: 2 years) in chronic anterior knee instability treated by ACL reconstruction associated to a lateral extra-articular plasty. Material and methods138 patients of a mean age of 27,8 +/- 8,5 years had been operated. Delay between injury and operation was 4 +/- 4,8 years. The surgical "Mac Injones" procedure used a tree autologous patellar tendon graft with a bone-to-bone fixation, supplemented by a lateral extra-articular plasty using a strip of quadriceps tendon as a direct prolongation of the graft of the patellar tendon and patella itself. A rehabilitation program aimed to an early recovery of a complete range of motion. Anterior laxity had been measured beforeand after operation using two instrumented methods, KT-1000 and stressradiography (at 20 degrees of flexion with a 9 kg load applied at the distal part of the thigh) with measurements of the displacement in medial and lateral compartments. Tunnel positioning was appreciated radiologically. Functionwas evaluated using the international Knee Documentation Commitee score (I. K.D.C.). ResultsElongation of the reconstructed ligament occured mainly during the first 6month, but was independant from early full range of motion recovery. Laxity was stabilized after one year. The final laxity gain of the medial compartment was 62 per cent and for the lateral compartment 77 per cent. The pivot shift test was negative in 66 per cent, grade 2 in 4 per cent, grade 1 in30 per cent. Functional results were excellent and good (A and B) in 60,4 per cent and 76,7 per cent returned to sports activity. 12 reconstructed ligaments reruptured. Arthritis was the cause of poor results in other cases (13,8 per cent). DiscussionLateral extra-articular plasty is unable to better control translation of the medial compartment than isolated anterior cruciate ligament reconstruction, but laxity of the lateral compartment was minimized and the Pivot shift test also, Incorrect position of the anterior cruciate ligament was correlated with poor results. ConclusionThis documented study on rarity of the two compartments confirms the interest of each type of reconstruction, in particular extra-articular plasty when made with quadriceps tendon and so doing, preserving the iliotibial-bandfor the control of varus stability.
