Two-stage ligament reconstruction effective to preserve function in knee dislocation, claims study
Two-stage ligament reconstruction with remnant preservation may preserve function in knee dislocation suggests a new study published in the BMC Surgery.
Knee dislocation is an uncommon and severe injury that frequently induced by high-energy impact injuries, ranging from automobile accidents to contact sports.
The purpose of this study was to evaluate the clinical outcomes of two-stage reconstruction (peripheral reconstruction in phase I and central anterior cruciate ligament (ACL) / posterior cruciate ligament (PCL) reconstruction in phase II) with remnant preservation for patients with knee dislocation.
A total of 70 patients (10 IIIM, 17 IIIL, and 43 IV) with knee dislocation were randomly divided into the remnant-preserved group and the simple reconstruction group. Patients underwent two-stage reconstruction, including the reconstruction of collateral ligament in phase I and the reconstruction of ACL/PCL in phase II (12 weeks after phase I). Grafts were harvested from the semitendinosus and gracilis tendons from both lower limbs. After the surgery, the joint flexion and extension, bone tunnel and ligament healing, and joint stability were evaluated.
