Abstract: Objective: To explore the clinical outcome of reconstructing the prosterior cruciate ligament(PCL) by combining the single-bundle and tibial-inlay techniques.Methods: Ten cases of grade Ⅲ PCL injuries were performed reconstruction of the PCL by combining the tibial-inlay and single-bundle techniques after definitely diagnosed by MRI.Results: All the patients were followed up for 10 to 24 months,and all the knee joint motion was in normal range with no exhibition of pain or other symptoms.The postoperative posterior draw test,reverse Lachman test and reverse pivot shift test were all negative.The postoperative Lysholm score was(88.5±2.5) points,which was increased significantly compared with the preoperative points of(58.6±5.3) (P<0.01).Conclusions: Reconstruction of PCL by combining the single-bundle and bibial-inlay techniques can obviously restore the function of the injured knee,and the clinical outcome is satisfactory.
