Purpose : The purpose of this study is to evaluate the clinical results after arthroscopic PCL reconstruction and to compare the clinical results after arthroscopic PCL reconstruction using BPTB(bone patellar tendon bone) autograft(Group I : 11 cases), Achilles tendon allograft(Group II : 7 cases) and BPTB allograft(Group 111.6 cases). Materials and Methods : We reviewed the result of 24 patients who had been managed with arthroscopic reconstruction using different graft materials such as BPTB autograft, Achilles tendon allograft and BPTB allograft. Twenty-four patients(average age, 37 years) with PCL rupture were retrospectively evaluated more than one year(average, 31 months) after having arthroscopic posterior cruciate ligament reconstruction. The clinical results were evaluated by IKDC ligament standard evaluation form, using $KT-2000^{TM}$ knee ligament arthrometer and also evaluated Lysholm knee scoring scale. Results : The final evaluation was nearly normal in 11 patients($45\%$ in Group I, $43\%$ in Group II, $50\%$ in Group III). The corrected posterior sagging was abnormal(side to side difference more than 6mm) in 8 patients($36\%$ in Group I, $29\%$ in Group II, $33\%$ in Group III). We could not find significant difference among three groups by IKDC scale. Conclusion : Comparing with other reports, our overall results were not satisfactory. And also, we could not find any remarkable difference among the three groups. Further research is necessary to evaluate new surgical approaches as well as improved techniques for capsular and collateral ligament injuries.

Purpose: The purpose of this study is to introduce the double bundle posterior cruciate ligament(PCL) reconstruction using Achilles allograft by the tibial inlay method and evaluate the clinical results of 11 cases who had PCL reconstruction using this method and were followed for more than 2 years after surgery. Materials and Methods: Our series consists of 11 cases of PCL reconstruction due to chronic posterior instability of knee and acute PCL rupture. The clinical results were assessed using the IKDC(International Knee Documentation Committee) scoring system, posterior stress radiographs and the maximum posterior displacement using a KT-1000TM arthrometer. Results: The average preoperative posterior displacement in 90 degree flexion stress radiograph was measured 13.4 mm and in 10 degree flexion the average posterior displacement using the KT-1000TM arthrometer was measured 11.4 mm. Postoperatively the 13.4 mm reduced to 4.4 mm and the 11.4 mm reduced to 3.9 mm. According to IKDC scoring system, 9 cases(81.8%) were satisfied. One case showed limitation of flexion with mild stiffness in the knee and another one case was not improved the posterior instability sufficiently and no complication of allograft was noticed. Conclusion: The double bundle PCL reconstruction using Achilles allograft by the tibial inlay method is a useful method for acute PCL rupture and chronic posterior instability of the knee including failed PCL reconstruction, because it will also make the posterior stability in the extension and 90 degree flexion position, and avoid the grafted tendon abrasion by acute turn of tibial tunnel.

Purpose: To assess the clinical results of ACL reconstruction with a fresh frozen Achilles allograft, retrospectively and the findings of the graft in second look arthroscopy. Materials and Methods: Twenty-eight ACL reconstructions using fresh frozen Achilles tendon allograft were included in this study between March 1999 and February 2003. The average age was 31.2 years old and the average follow-up was 16.6 months(range: 12-26 months). The clinical evaluation was done by KT-1000 arthrometer, Lysholm knee score, range of motion, Lachman and pivot-shift test. Results: In the last follow-up of Lachman test, 21 cases showed normal, 5 cases grade 1, 2 cases grade 2 and 1 case grade1. The results of pivot-shift test data, 23 cases(82.1%) were normal, 4 cases(14.3%) grade 1, 1 case(3.6%) grade 2. The mean maximum side-to-side difference was improved from 6.75mm preoperatively to 2.46mm in the last follow-up. Lysholm knee score was improved from 73.5 preoperatively to 91.6 in last follow-up. Re-rupture of the ACL graft was found in one case and one case of wound infection in the tibial incision was found. The 6 cases showed the good synovialization of the ACL graft. Conclusion: The anterior stability was restored with ACL reconstruction using fresh frozen Achilles allografts and the good synovialization was found in the second-look arthroscopy
