Study favors bone-patellar tendon-bone autograft over autograft in ACL reconstruction

Researchers compared bone-patellar tendon-bone autografts and allografts in this study and found patients with autografts had better subjective scores. However, patients with allografts were more likely to return to pre-injury activity level, had improved knee pain scores and better overall International Knee Documentation Committee Scores.

“Patients undergoing ACL reconstruction with [bone-patellar tendon-bone] BPTB autografts demonstrate lower rates of graft rupture, lower levels of knee laxity, and improved single-legged hop test results and are more generally satisfied postoperatively compared with patients undergoing reconstruction with allograft BPTB,” Matthew J. Kraeutler, BS, and colleagues wrote in the study abstract.

In a meta-analysis of 76 studies, Kraeutler and colleagues identified 5,182 patients in studies where patient satisfaction, return to pre-injury level and postoperative functional outcomes were analyzed, according to the abstract. Patients with autografts had improved Lysholm, Tegner, International Knee Documentation Committee (IKDC) and KT-1000 arthrometer scores.

Single-legged hop and anterior knee pain scores as well as overall IKDC scores were higher in the allograft group. However, researchers noted the rupture rate was three times higher in the allograft group than the autograft group.
