Abstract

SummaryTwo-hundred-sixteen allograft bone-patellar ligament-bone fresh-frozen allograft anterior cruciate ligament (ACL) reconstructions were performed from September 1985 to May 1992. All patients underwent an aggressive rehabilitation program that emphasized early unrestricted motion and functional weight-bearing, with return to unrestricted sports activities typically occurring 6 months after surgery. Ninety-three patients returned for follow-up evaluation an average of 30 months (range 24–51 months) after reconstruction. Ninety-two percent of patients felt their knees had improved or returned to normal following surgery, and 87% achieved good or excellent results when evaluated with the Lysholm Knee Score. Objectively, 89% of patients exhibited a 0 to 1 + Lachman score with a solid endpoint. and 86% had =≤ 3 mm difference on KT-1000 testing. Using the modified Hughston Knee Evaluation system to combine the subjective, functional, and objective portions of the evaluation, 80% of the patients achieved good or excellent results. There were 10 graft failures. Our results are comparable to those previously reported in the literature for both allograft and autograft ACL reconstruction. We have found our results using allograft tissue in ACL reconstruction to be of equal value to those obtained with autograft tissue, with allograft recipients experiencing less early postoperative morbidity.
