Prosthetic versus tendon allograft replacement of ACL-deficient knees.
ACL reconstruction is still controversial. Between November 1985 and October 1987, 57 ACL reconstructions were performed using a Dacron graft. Evaluation was done using the Lysholm rating system and Tegner scale. The Lysholm score averaged 84.2. Regarding the level of performance, the patients had lost an average of 2.1 points on the Tegner scale. 18 of the 57 patients developed a synovitis. In 11 patients (19 per cent) the implant had to be removed. CT scan of the operated knee proved the Dacron graft to be nonfunctioning in as many as 40 per cent of the patients. Because of this high complication rate, the authors started to use deep-frozen (-70 degrees C) tendon allograft material. Both Achilles and Tibialis Posterior tendons were implanted using the over-the-top technique with or without an additional extra-articular procedure. Complications as seen with the rigid synthetic ligaments were absent. The preliminary results seem satisfactory in that the functional demands placed on the knee are not restricted.
