Posterior Cruciate Ligament Reconstruction Using Hamstring Tendon with Preservation of Posterior Cruciate Ligament Remnant

ABSTRACT

PURPOSE: The purpose of study is to evaluate the clinical results of posterior cruciate ligament (PCL) reconstruction using the quadruple hamstring tendon with preservation of the PCL remnant. SUBJECTS AND METHODS: Twenty PCL reconstructions have been performed by one surgeon. The average follow-up period were at 31 months. There were 11 isolated injuries and 9 associated injuries. The clinical outcome was assessed by preoperative and postoperative posterior displacement at stress radiograph, Lysholm knee score and complications. RESULTS: At last follow up Lysholm knee scores improved from 60 preoperatively to 92 postoperatively. The average preoperative posterior displacement at stress radiograph was 14 mm and postoperatively it was 3.2 mm. The average postoperative posterior displacement at stress radiograph was 2.6 mm in isolate injury and 3.7 mm in associated injury. The average postoperative posterior displacement at stress radiograph was 2.6 mm in case of reconstruction within three weeks and 3.7 mm in case of reconstruction after three weeks. CONCLUSION: Good stability and function of knee could be obtained by PCL reconstruction using hamstring tendon with preserving the PCL remnant and non-aggressive rehabilitation.
