Introduction
Remnant, automobile accidents, dislocation, knee dislocation
Knee dislocation is an uncommon and severe injury that frequently induced by high-energy impact injuries, ranging from automobile accidents to contact sports [Until now, the treatment principle for cruciate ligament injuries following knee dislocation is still controversial. Some scholars recommend that ligament reconstruction should be performed as early as possible after knee dislocation [Remnant preservation is a technology to make full use of the remnant to improve the surgical outcomes of ligament reconstruction, especially for ACL reconstruction [In this study, a two-stage reconstruction was performed in patients with knee dislocation. In the phase I, we performed a simple reconstruction of the collateral ligament. When the knee flexion and extension recovered to preoperative range following phase I reconstruction for at least 12 weeks, ACL/PCL reconstruction was subsequently performed. This study aimed to evaluate the clinical effects of two-stage reconstruction of ACL/PCL with remnant preservation, providing a good choice for the treatment of knee dislocation.
