Posterior cruciate ligament (PCL) injury hampers the rotational stability and stability front to back of the knee joint, seriously affecting the quality of life of patients. Some studies have reported that the peroneus longus tendon (PLT) has sufficient length and strength.
We hypothesized that the PLT can be used as a novel appropriate material for PCL reconstruction therapy. Materials and methods: Herein, we systematically analysed the clinical effect of the double-stranded PLT and the four-stranded hamstring tendon in the reconstruction of the PCL and compared the effectiveness and safety of these two surgical approaches in the reconstruction of PCL injury. A total of 48 patients with complete rupture of the PCL were divided into Group A (reconstructed with the double-stranded PLT, 25 cases) and Group B (reconstructed with the four-stranded hamstring tendon, 23 cases).
The patients were followed up for more than 1 year. The intraoperative time for tendon extraction was significantly shorter in Group A than Group B. Twenty-four months after operation, patients in the two groups showed the alleviated tibial posterior displacement and the increased IKDC score, Lysholm score and Tegner score. Nevertheless, these scores showed no significant differences between the two groups. Additionally, compared with the therapy using the four-stranded hamstring tendon, therapy using the double-stranded PLT is simpler and safer.
Both surgical methods are effective in the treatment of PCL injury. The PLT could be a good choice for PCL injury reconstruction material, especially when the four-stranded hamstring tendon is accidentally damaged or ineffective. Our study may provide guidance for the clinical treatment of PCL injury.
