Functional Outcomes and Hop Tests Results in ACL Reconstruction Patients with Adjustable Loop Fixation: 2 Years Follow-up

BACKGROUND: Arthroscopic Anterior Cruciate Ligament (ACL) reconstruction is one of the most performed knee surgery, which results in early return to sport and good clinical outcomes. The outcomes are affected by various factors, namely type of grafts, graft fixation methods, tunnel orientations and diameters. If good operative results and intensive pre- and post-operative rehabilitation lead to an optimal outcome, patients can return to the pre-injury level of sports activity in the short term. OBJECTIVE: Muscle strength and stability of anterior cruciate ligament in reconstructed knees have been bilaterally compared with The Peroneus Longus Tendon grafts at preoperative, 6 month and 2 years following surgery. METHODS: Forty-seven patients, 40 men, and 7 women, participated in the study. The outcome measures using IKDC, Cincinnati and Tegner-Lysholm score. Hop tests were evaluated on 6th month after the surgery. RESULTS: Results of preoperative and 2-years postoperative functional outcomes are shown the IKDC score, Tegner-Lysholm score, and Cincinnati score yielded statistically significant differences (p<0.001) between their pre- and postoperative score from 56,3% until 98,0%. The median of the hop tests were 92, 94, 94, and 95, for the single, triple, cross over, and timed tests, respectively CONCLUSION: In this retrospective study of 47 patients undergoing ACL reconstruction with adjustable loop fixation (GraftMax™ Button, CONMED) on the femoral site and peroneus longus tendon autograft, we found that in 2 years of follow up, the functional outcomes and hop tests were favorable. Good surgery technique and intensive pre- and post-surgery rehabilitation are very important. Six months after surgery patients are allowed to go back to sports activity.
