[Acute anterior cruciate ligament repair with combined intra- and extra-articular reconstruction using an iliotibial band with the modified MacIntosh technique: a five-year follow-up study of 50 pivoting sport athletes].
OBJECTIVE
Comparisons have been often made between bone-tendon-bone plasty and hamstring tendon four-strand plasty. Whether a lateral tenodesis should be associated with the intra-articular reconstruction and the appropriate time between the accident and the repair remain two topics of debate. We present results obtained in a consecutive series of 50 pivoting sport atheletes reviewed retrospectively. These patients had been treated within eight days of trauma with a modified MacIntosh technique using an iliotibial band. This technique enables lateral tenodesis and reconstruction of the central pivot with only one harvesting site. We searched for responses to two questions: are our results comparable to those in other published series? could this operation be warranted as an emergency procedure?


METHODS
Fifty patients from a consecutive retrospective series of 62 patients (eight lost to follow-up and four excluded from the analysis) were reviewed by an independent observer at mean follow-up of 5.2 years (range 54.4 to 86.4 months). The ARPEGE and IKDC scoring systems were used. An isokinetic assessment was obtained in 38 patients at one year. The reconstruction technique used an iliotibial band measuring 40-45 mm in width. The lateral reconstruction consisted in section then translation of the lateral intermuscular partition.


RESULTS
The overall outcome was scored as follows: IKDC A 38%, B 46%, C 12%, D 4%. Mean residual differential laxity (KT 1000) was 1.86+/-1.74 assessed manually with a negative Lachman in 48% of knees. 88% of the positive tests had been neutralized. Early anatomic failure was noted in two knees with recurrent traumatic tears at 25 and 38 months. Using the ARPEGE scoring system, outcome was excellent in 38%, good in 46%, fair in 12% and poor in 4%. At last follow-up, the level of sports activities was unchanged in 33 patients. Irreducible flexion measuring more than 5 degrees was noted in two patients, and a deficit in flexion greater than 20 degrees in three. One female athlete who had resumed her former sports level presented mobilization under narcosis. None of the patients complained of pain at the harvesting site. There was one case of muscle herniation proximally by wound dehiscence. Mean residual deficit of the quadriceps, measured at twelve months, was 10% at 90 degrees /s; mean residual deficit of the hamstrings at the same speed was 1.3%.


CONCLUSIONS
Our overall results as measured with the IKDC scoring system were comparable with those observed in series using other autologous transplants. The risk of stiffness is greater with early reconstruction, suggesting emergency repair should be considered with caution. Recovery of muscle force demonstrates one of the advantages of using the iliotibial band which does not injure the extensor-flexor system of the knee joint. The fact that none of the patients complained of pain at the harvesting site is a favorable element for rehabilitation and resumed sports activities.
