Comparative study of arthroscopic reconstruction of anterior crucial ligament with autograft and aliograft of bone-patellar tendon-bone / 中华创伤杂志

ABSTRACT

Objective To compare the effect of allograft and autograft of bone-patellar tendon- bone (B-PT-B) under arthroscopy in reconstruction of anterior cruciate ligament (ACL).Methods The injured ACL was reconstructed under arthroscopy by using autograft of B-PT-B in 30 cases and al- lograft of B-PT-B in 28 cases from January 2000 to August 2003.After over twelve months follow up,a comparison was done on rehabilitation of quadriceps femoris,knee stability,the Lysholm's score of knee and the enlargement of tunnel in both groups.Results Both groups obtained marked improvement of knee stability and symptoms after operation.But in the early time,the rehabilitation of quadriceps femoris in the ailograft group is faster than that in the autograft group.The rehabilitation of quadriceps femoris, knee stability and the Lysholm's score of knee were similar at 12th month (P＞0.05).There could be seen enlargement of tunnel in both groups,with more in the allograft group (P＞0.05).Conclusion For arthroscopic reconstruction of anterior crucial ligament (ACL),allograft of B-PT-B is good substitute, for it is characterized by effectiveness,convenience and minor side effect.
