A long-term study of anterior cruciate ligament allograft reconstruction.
We retrospectively reviewed the long-term clinical outcome of unilateral arthroscopic anterior cruciate ligament (ACL) allograft reconstruction. From October 1995 to December 1997, 64 arthroscopic ACL reconstructions were performed. Multiligamentous knee injuries and ACL injuries in polytrauma patients were excluded and out of the remaining 60 patients 55 were available for follow-up. Three patients had suffered a rerupture caused by major trauma. One patient had a rerupture without significant trauma and one failure was caused by deep infection. These five patients were revised. Fifty patients (36 males, 14 females) were included in the final follow-up. At the time of evaluation, the mean duration of follow-up was 10 years and 6 months. All patients were examined by an independent examiner. Seven patients had an extension lag (<5 degrees) and all patients had a knee flexion of at least 120 degrees, with a mean flexion of 135 +/- 5 degrees compared to 135 +/- 8 degrees. At the time of follow-up, the median IKDC score was 97 (74-100). The Lysholm scoring scale had a median value of 95 (76-100). The median sports level on the Tegner scale was 6 (4-9). The one-leg-hop test showed a mean value of 95 +/- 5%. One patient did not perform the one-leg-hop test because of recent surgery to the Achilles tendon. In conclusion, the tibialis anterior or tibialis posterior tendon allograft ACL reconstruction produced good clinical results in the majority of patients at long-term follow-up.
