Thirty-nine revision of ACL reconstructions were evaluated: 23 primary
ACL reconstructions with bone-patellar tendon-bone graft (BPTB) revised with
hamstring tendon (HT) grafts, 10 primary ACL reconstructions with HT grafts
revised with ipsilateral BPTB graft (iBPTB) and finally 6 primary ACL
reconstructions with BPTB grafts revised with contralateral BPTB (cBPTB) grafts
were compared with 78 primary ACL reconstructions (46 HT grafts and 32 BPTB
grafts). Recovery of isokinetic muscle strength was evaluated at 4, 6 and 12
months post-revision surgery. RESULTS: Deficits in muscle strength at 12 months
post-revision ACL surgery were comparable to the one observed for primary ACL
reconstruction with the same technique. At 4 and 6 months post-surgery, strength
deficits for the knee extensors were less pronounced after revision ACL
reconstruction with HT grafts (25%+/-16 vs. 37%+/-16; P<0.001) and iBPTB grafts
(41%+/-11 vs. 17%+/-17; P<0.001). DISCUSSION: Lower strength deficits for the
knee extensors after revision ACL reconstruction with HT grafts can be explained
by a less intensive rehabilitation program due to lower stakes in resuming sport
activities. With cBPTB, donor-site morbidity could explain the decreased strength
deficits for knee extensors. CONCLUSION: Deficits in isokinetic muscle strength
after ACL revision seem similar to the ones observed after primary ACL
reconstruction with the same surgical technique.
