Double-bundle Anterior Cruciate Ligament Reconstruction tech
A Study was conducted to compare the long-term clinical outcomes of single-bundle anterior cruciate ligament reconstruction (SBR) and double-bundle anterior cruciate ligament reconstruction (DBR) in patients with isolated anterior cruciate ligament (ACL) rupture, presenting no meniscus injury and no obvious preoperative cartilage degeneration.

103 patients with a median follow-up of 151.6 months completed the retrospective study (SBR group: n=51; DBR group: n=52). Clinical outcomes were evaluated with physical examinations, KT-2000 anterior and posterior stability measurement with the knee in 30º of flexion, International Knee Documentation Committee (IKDC) subjective score, Tegner score, Lysholm score; (MRI) (3.0 T) was performed, and International Cartilage Repair Society (ICRS) cartilage degeneration grades were determined.

--There were significant differences in the pre- and postoperative IKDC, Lysholm and Tegner scores between the SBR and DBR groups.

--The SBR group had over double the rate of positive pressure/rub patellar test results.

--The KT-2000, pivot-shift and Lachman test results were stratified and analyzed, and significant differences between the SBR and DBR groups were found.

--The distribution of ICRS grades differed significantly between the groups at the last follow-up.

--A multivariate analysis found that age and operation procedures were significant predictors of 0 and non-0 ICRS grades and 0.210.

To summarize, both SBR and DBR produced good long-term results. DBR was superior in avoiding cartilage deterioration and had advantages in objective outcome metrics. Age was found to be a preoperative risk factor for substantial cartilage deterioration after surgery.
