Outcome of adjustable suspensory fixation for femoral graft in acl reconstruction

RESUMO

Background: The incidence of torn anterior cruciate ligament (ACL) has greatly increased, with today's increasing enthusiasm for sports activities. As a result, reconstruction of the torn anterior cruciate ligament became a common surgical procedure in orthopaedic surgery. Objective: To evaluate short term clinical outcome of adjustable suspensory fixation for femoral graft in ACL reconstruction. Methods: All patients treated for ACL reconstruction with an ipsilateral hamstring between March 2017 and March 2018 were evaluated. Subjects were assigned to TightRope™ (TR) femoral fixation. All patients were evaluated with the Lachman test, pivot-shift test, 2000 International Knee Documentation Committee (IKDC) knee examination. The subjective evaluation was performed using the Lysholm knee score. CT examination was performed to evaluate femoral and tibial tunnels enlargement at four different levels. All patients were assessed at a 12 month follow-up visit. Power analysis was performed a priori in accordance with the femoral and tibial tunnels enlargement values from the CT scans. Results: The group was homogenous at baseline with regard to age, gender, BMI, dominance and disease duration. At the final follow-up, no statistically significant differences were found according to subjective and objective clinical outcome measures. According to the femoral tunnel enlargement, no statistically significant difference was found between tunnel at operation and 12 months later. Conclusion: In transtibial ACL reconstruction, the use of adjustable-loop length device products, on the femoral side, led to better clinical and radiological results:
