Early outcome analysis of arthroscopic anterior cruciate ligament reconstruction using fixed closed loop and adjustable loop techniques: A prospective case series

Abstract

CONTEXT: Anterior cruciate ligament (ACL) reconstruction has remained the gold standard for ACL injuries, especially for young individuals and athletes expose to high-level sporting activities aiming to return preinjury level of activity. Femoral cortical suspension devices have gained popularity. However, there are limited studies specifying a superior graft fixation technique. AIMS: To evaluate outcome of arthroscopic ACL reconstruction using fixed closed loop fixation (CLF) and adjustable loop fixation (ALF) techniques. SETTINGS AND DESIGN: Prospective case series. MATERIALS AND METHODS: 40 cases were included in the study, among of which 20 cases, underwent arthroscopic CLF and another group of 20, who were operated on using ALF. Clinical outcome was assessed using manual tests, i.e., Lachman and pivot shift, and results were graded using the International Knee Documentation Committee. Lysholm score was used to evaluate functional outcome up to 6 months. STATISTICAL ANALYSIS USED: Data were analyzed using SPSS version 21. RESULTS: There were no significant differences in manual Lachman and pivot shift grading in both groups. One case (5%) in CLF group and 15% in ALF group were showed Grade B clinically laxity by Lachman, and one case (5%) in CLF group and 10% in ALF group were showed Grade 2 + rotatory laxities by pivot shift. The study found no statistically significant differences in functional score between the groups (P = 0.245). CONCLUSIONS: In femoral fixation of ACL graft both CLF and ALF techniques may provide secure fixation, equal reduction of graft laxity, and similar functional outcome in ACL deficient knee.
