TL;DR
This study found that ideal tunnel angles in ACL reconstruction improve long-term knee function but do not affect osteoarthritis progression.
Contribution
The study identifies specific tunnel parameters that significantly influence clinical outcomes after ACLR.
Findings
Ideal coronal tibial and femoral tunnel angles improve clinical outcomes like pivot shift test results.
Ideal coronal tibial tunnel position enhances objective knee function scores (IKDC).
No tunnel parameters or graft angles influenced osteoarthritis progression in the long term.
Abstract
Objective To study the influence of various tunnel parameters and graft inclination angle (GIA) on the clinical and radiological outcome after anterior cruciate ligament reconstruction (ACLR) at long-term follow-up. Methods In this retrospective study, 80 patients with isolated anterior cruciate ligament (ACL) injury treated by single bundle ACLR using bone patellar tendon bone (BPTB) and hamstring (HT) autografts were evaluated clinically and radiologically at their long-term follow-up. The study population were divided into two groups based on ideal and nonideal tunnel parameters as well as ideal and nonideal GIA. The various tunnel parameters and GIA were interpreted with clinical and radiological outcome at long-term follow-up. Results Eighty patients, 36 (45%) using BPTB and 44 (55%) using HT autografts, were available to complete the study. Patients with ideal coronal tibial…
