title: [Mid-term results of 173 cases of surgery of the anterior cruciate ligament using the Mac Intosh procedure, reinforced by the Kennedy Ligament Augmentation Device].
abstract: This is a retrospective study of 173 chronic laxities of the knee operated on between May 1985 and December 1988 using the Mac Intosh procedure, reinforced by the Kennedy L.A.D. Follow-up was between 4-8 years and the same surgeon operated on all the knees.
  
  
  METHODS
  171 patients were operated on (113 men and 58 women) aged between 15-49 years (average age 26.5 years). The vast majority were sportsmen both at competition level (51 cases) and at recreational level (119 cases). The average time-span between accident and intervention was 15 months (1-240 months). In the pre-operative assessment, 80 cases (46.2 per cent) were found to have a grade II Lachman test and 91 cases (52.6 per cent), a grade III Lachman test; a positive pivot shift was found in more than 95 per cent of cases. There were lesions of the medial meniscus in 101 cases (58.4 per cent), of the lateral meniscus in 94 cases (54.4 per cent) and there was no meniscal lesion in only 41 cases (23.8 per cent). Finally there were 22 chondral lesions of the medial femoral condyle (12.7 per cent) and 7 of the lateral condyle (4.1 per cent).
  
  
  RESULTS
  These were based on 159 cases (14 lost to follow-up before the third post-operative month), but only 107 (61.8 per cent) were reviewed by one of us (i.e. not the original surgeon). Tolerance of the L.A.D. was excellent. There was no sign of synovitis or joint effusion persisting beyond 1 year. Furthermore, there were no serious complications (no sepsis, only 4 cases (2.3 per cent) of joint stiffness, 2 cases of reflex sympathetic dystrophy and 5 cases of sural phlebitis (2.9 per cent). Moreover, the few minor complications that arose resolved with the appropriate treatment. Anatomical results, evaluated using. Lachmans test (maximum manual Lachman measured with the Bercovy Laximeter) showed 24 cases (22.4 per cent) with zero differential residual laxity, 54 cases (50.5 per cent) with a differential laxity of between 0-2 mm; 20 cases (18.7 per cent) with a laxity of between 2-4 mm and in 9 cases (8.4 per cent) a laxity of greater than 4 mm. Functional results, using the Arpège C.L.A.S. system showed good results in 83 per cent (score > and unsatisfactory results in 17 per cent of cases. The long time-span between intervention and subsequent review with the C.L.A.S. system should be taken into account. However, the proportion of competitive sportsmen to recreational sportsmen was practically identical when comparing pre-traumatic figures (C = 29.5 per cent, R = 68.8 per cent) to figures at the time of follow-up (C = 21 per cent, R = 69.5 per cent). Radiological results (A.P. and Schuss films) showed 63 knees (58.9%) with no signs of either medial or lateral, preliminary or full-blown, femoro-tibial osteo-arthritis.
  
  
  CONCLUSIONS
  With an average follow-up of > 5 years (4-8 years), it is possible to say that ligamentoplasty of the anterior cruciate ligament using the Mac Intosh procedure reinforced with the Kennedy L.A.D. is not causative of any iatrogenic problems. The anatomical results were totally satisfactory (almost normal) in 72.9 per cent of cases; the radiological results showed ""normal'' knees in 58.9 per cent of cases and functional results were identical to results obtained using many other techniques.
