TL;DR
This study shows that using hamstring tendons to reconstruct both knee ligaments in one surgery leads to improved function and stability with minimal complications.
Contribution
A novel bicruciate reconstruction technique using bilateral hamstring autografts in a single-stage procedure is proposed and evaluated.
Findings
Lysholm knee function scores improved significantly from 43.8 to 89.9 post-surgery.
Post-surgery anterior knee laxity decreased from 5.2 mm to 2.4 mm.
Posterior tibial translation reduced from 10 mm to 3 mm after surgery.
Abstract
Objective The purpose of this study was to evaluate the clinical and functional results of simultaneous reconstruction of the ACL and PCL with bilateral hamstring autografts. We hypothesized that this reconstruction technique results in less morbidity and has similar results to the ones published in the previous literature. Methods Eighteen patients with bicruciate lesions were selected and treated by arthroscopic surgery with autologous hamstring tendons in a single-stage procedure. The thicker semitendinosus tendon (ST) and the two gracilis tendons (G) were used for a 6-strand PCL reconstruction. The thinner ST was used for a 3-strand ACL reconstruction. The average patient age at surgery was 31 years, and the minimum follow-up was 2 years. Function of the operated knee was evaluated according to the Lysholm scale. Anterior knee laxity was examined with a KT-1000 arthrometer.…
