The results of these anterior cruciate ligament reconstruction revision surgeries are close to those achieved by other series of primary reconstructions with a little less satisfactory results. We attribute the high success rate to the strict application of the same technique and the confinement of revision to motivated patients. It should be noted, however, that follow-up is only at the midterm stage (mean, 41.9 months).

We compared motor control function in 50 patients who had undergone anterior cruciate ligament reconstruction using a bone-tendon-bone graft to that in 50 normal controls. Surgical subjects patients had undergone reconstruction with a one- (n=37) or two-incision (n=13) technique with the same rehabilitation protocol; mean time from the index surgery was 6.1 years (range of 5-8 years). For inclusion patients required an excellent outcome, category A IKDC score, and a KT-1000 side-to-side difference of 3 mm or less. Motor control evaluations were conducted using the KAT 2000 with static and dynamic tests. Normal controls had substantially better scores than did the surgical patients. There was no statistical difference the single-limb static test between scores of operated and nonoperated limbs. However, the operated limb scores were slightly better overall than those for the nonoperated limb, and the right knee scores tended to be better than those for the left knee. This may be explained by limb dominance. The test method employed in this investigation shows that anterior cruciate ligament reconstructed patients had a clear motor control deficit compared to normal control subjects even after several years.

An account of a prospective study of anterior cruciate ligament reconstructions with the bone-patellar tendon-bone autograft (BPTB) and the doubled semitendinosus-gracilis autograft (ST-GR) is given in 39 patients and 22 patients, respectively. The BPTB patients were younger, and there were more women in the ST-GR group. There were no statistical differences in the clinical and instrumental evaluations of stability after 1 and 2 years (Lachman and Jerk test, KT1000) between the two groups. Slightly better results were obtained in the BPTB group: mean 0.80 and 0.96 (first and second years) versus 1.18 and 1.20. Both methods, in fact, resulted in very satisfactory anterior knee stability, even when applied in two dissimilar groups of patients.

The results of these anterior cruciate ligament reconstruction revision surgeries are close to those achieved by other series of primary reconstructions with a little less satisfactory results. We attribute the high success rate to the strict application of the same technique and the confinement of revision to motivated patients. It should be noted, however, that follow-up is only at the midterm stage (mean, 41.9 months).
