Purpose: The purpose of this study was to compare the clinical results of the arthroscopic anterior cruciate ligament reconstruction used by Bone-Patella tendon-Bone autograft and Achilles tendon allograft. Materials and Methods: We reviewed the results of patients who had been managed with arthroscopic anterior cruciate ligament reconstruction using different graft such as Bone-Patella tendon-Bone autograft and Achilles les tendon allograft. 60patients (average age, 33.5 years)were retrospectively evaluated. The one group(average age, 33.4 years) was 32 patient who had been managed with arthroscopic anterior cruciate ligament reconstruction using Bone-Patella tendon-Bone autograft. The other group(average age, 32.1 years) was 28 patient who had been managed with arthroscopic anterior cruciate ligament reconstruction using Achilles tendon allograft. 2 groups were evaluated subjectively by Lysholm knee scoring scale and objectively by KT-2000 arthrometer. The follow-up period was more than a year(average, 18 month). An early rehabilitation protocol was instituted. Results: On Lysholm knee scoring scale, the final evaluation was nearly normal in all patients. We could not find statistical difference among the two groups by KT-2000TM arthrometer. Conclusion: The use of allografts may be an acceptable choice for ACL reconstruction.

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.

Introduction: The purpose of this study is to assess the efficacy of calcium sulfate as a bone graft substitute in the treatment of benign bone tumor. Materials and Method: Between December 2000 and November 2001, 18 patients with a benign bone tumor were treated with crettage and the defects were filled with calcium sulfate (Osteoset$^{(R)}$:Wright Medical Co. USA) as a bone graft substitute. Average age was 28.4 years and mean follow up period was 12.3 months. Calcium sulfate mixed with autograft was used in 6 cases, calcium sulfate with allograft in 2 cases, and calcium sulfate alone was used in 10 cases. The degree of absorption of calcium sulfate and new bone formation at plain radiograph was analyzed at immediate postoperative and postoperative 3 months and 6 months follow up. Results: At 3 months postoperatively, 92% of calcium sulfate was absorbed, and at 6 months postoperatively, 89% of new bone formation was observed. There was no difference in the resorption and new bone formation between the group using bone graft and the group osteoset$^{(R)}$ alone, different preoperative diagnosis and even different locations. There was no complication. Conclusion: Calcium sulfate(Osteoset$^{(R)}$) is a safe and effective bone graft substitute in the treatment of benign bone tumors, especially for the children in whom autograft is not recommandable.
