Description
Purpose The purpose of this study was to compare the outcome of primary anterior cruciate ligament (ACL) reconstruction between Achilles tendon allograft with tibial anatomical bifixation and bone-patellar tendon-bone (BPTB) allograft with tibial external aperture fixation. Materials and methods From July 2005 to January 2008, 169 patients underwent primary ACL reconstruction were randomly assigned to two groups, with 80 patients with Achilles tendon-bone allograft (Group A), and 89 patients with BPTB allograft (Group P). Patients were available for clinical evaluation with KT-1000 knee ligament arthrometer, radiographic tunnel measurement, and knee function with the International Knee Documentation Committee (IKDC), Lysholm and Tegner scores. Results A total of 73 patients were followed up at an average of 36.7 months (range 25–55 months) in group A and 79 patients with an average follow-up of 37.3 months (range 26–54 months) in group P. The average side-to-side difference was lesser for group A (1.70 ± 1.52 mm) than for group P (2.43 ± 1.74 mm) (P = 0.032), with 1.4% versus 5.1% of greater than 5 mm, which was considered as laxity failure. Bone tunnel enlargement rate was lower for group A than for group P, 21.9 and 38.0% on anterior– posterior radiographs (P = 0.031), 24.7 and 44.3% on lateral radiographs (P = 0.011). All knee function scores were improved postoperatively, without statistically significant difference between the two groups. Conclusion Primary ACL reconstruction with Achilles tendon allograft with tibial anatomical fixation had significant better knee stability and lower bone tunnel enlargement rate than that of BPTB allograft with tibial external aperture fixation.
