Abstract

OBJECTIVE:

To compare the effectiveness of anterior cruciate ligament (ACL) reconstruction between the ligament advanced reinforcement system (LARS) and bone-patellar tendon-bone (BPTB) autograft.

METHODS:

Between July 2007 and July 2011, 50 cases (50 knees) of ACL injury were treated with LARS in 24 cases (LARS group) and with BPTB in 26 cases (BPTB group), respectively. There was no significant difference in age, gender, time from injury to surgery, and injury reason between BPTB group and LARS group (P > 0.05). The postoperative rehabilitation protocol was performed in 2 groups.

RESULTS:

All incisions healed at the first stage. All patients were followed up 2-3 years. The results of Lachman test, anterior drawer test, and pivot shift test were negative. Screw loosening in femur and tibia occurred in 1 case of each group respectively, anterior knee pain in 2 cases of BPTB group and in 1 case of LARS group. The Lysholm and Tegner scores were significantly higher in LARS group than in BPTB group at 2 and 6 months after operation (P < 0.05); but no significant difference was found between 2 groups at 12 and 24 months (P > 0.05). The IKDC scores showed no significant difference between 2 groups at different time points after operation (P > 0.05). During follow up, KT-1000 arthrometer and knee stability showed significant differences in antedisplacements of the tibia between 2 groups at all time points after operation (P < 0.05).

CONCLUSION:

LARS has less trauma and earlier functional recovery than BPTB autograft for ACL reconstruction, but the long-term effectiveness is similar.
