REVISION ANTERIOR CRUCIATE LIGAMENT SURGERY - EXPERIENCE FROM CINCINNATI

Prospective studies were done to determine the outcome of allografts a nd autografts used for revision anterior cruciate ligament reconstruct ion, The allograft group was comprised of 65 patients observed for a m ean of 42 months postoperatively; the autograft (bone-patellar ligamen t-bone) group contained 20 patients observed for a mean of 27 months p ostoperatively, KT-2000 testing and a comprehensive knee examination w ere done on all the patients, The Cincinnati Knee Rating System was us ed for assessment, Significant improvements were noted in all patients for symptoms, functional limitations, anteroposterior displacements, pivot shift tests, and overall rating scores, KT-2000 results showed 5 3% of the allograft group and 67% of the autograft group had less than 3 mm increased displacement (not statistically significant). The over all failure rates were 33% for the allografts and 27% for the autograf ts, Preoperative planning and technical aspects of anterior cruciate l igament revision procedures are described, The authors prefer bone-pat ellar ligament-bone autografts for anterior cruciate ligament revision , although the data presented were considered preliminary, Bone-patell ar ligament-bone allografts may be used when autogenous tissues are no t available, because they offer reasonable success rates for patients who are symptomatic with daily activities.
