- W2102480209 abstract "Although, recently, it has been reported that posterior cruciate ligaments(PCLs) have spontaneous healing potential and can heal by conservative treatment, despite good early functional results, the posterior laxity of the knee is not completely eliminated after conservative treatment. The PCL can retain the normal tension only when the injured ligament is maintained anatomically. The purpose of this study was to develop and evaluate a technique of PCL reconstruction with stent operation for remnant PCL augmentation. Between September 2003 and March 2006, 23 patients who had a tear of the PCL underwent reconstruction with stent operation using hamstring tendon graft(20cases) or tibialis posterior allograft(4 cases) for remnant PCL augmentation. 20 patients were evaluated after a minimum duration of follow-up 24 months. The remnant PCL and the synovium were preserved, and the augmentation was performed using transtibial technique. Femoral tunnel was created at near the foot-print of anterolateral bundle. Stability was measured on posterior stress radiographs and with a maximal manual displacement test performed with a KT-1000 arthrometer. Clinical evaluation was carried out with use of the scoring systems of the international Knee Documentation Committee(IKDC) and the Orthopadische Arbeitsgruppe Knie Score(OAK). The mean side-to-side differences in displacement was reduced from 9.9 ± 4.0 mm preoperatively to 3.0 ± 2.6 mm at last follow-up on the stress radiographs, and it was reduced from 6.9 ± 2.1 mm preoperatively to 2.7 ± 1.5 mm as measured with the KT-1000. The final IKDC score was A in 7(35%), B in 10(50%), C in 2(10%) and D in 1(5%) patients. The average OAK score improved from 61.6 ± 13.1 to 88.2 ± 9.5. The group in which tibialis posterior allografts were used for augmentation showed worse results than hamstring autograft group in clinical result. In one case, posterior instability was recurred more than 10mm compare to contralateral side, PCL revision was performed as a double bundle reconstruction using achilles allograft. Excellent posterior stability and relatively good clinical results were achieved with the stent operation for remnant PCL augmentation. This technique is technically feasible and the PCL remnants and synovium may be beneficial to ligament healing and proprioception. However, other combined injuries seem to affect clinical results. The short-term results are encouraging, but long –term results are needed to confirm the value of this technique for alternative operative method of acute or subacute PCL injuries." @default.
