Purpose: To evaluate the long term outcomes of the ACL reconstruction from the standpoint of osteoarthritis.
Materials and Methods: We evaluated 31 patients who underwent ACL reconstruction from April 1986 to April 1999 and could be followed-up more than 7 years. Mean follow-up period was 10.1 years (7~22 years). In terms of the graft, 11 cases were treated with the ACL reconstruction using a autologous hamstring tendon graft, 20 cases were treated with using a autologous bone patellar tendon bone graft. For femoral tunnel, 11 cases were placed through transtibial tunnel, 20 cases were placed through anteromedial portal using mini-open arthrotomy. Functional and radiographic evaluation was performed.
Results: Mean Lysholm score was 89.2±11.7 points. Patients had KT-2000 side-to-side differences were 2.1±1.9 mm. IKDC ligament evaluation showed 38.7% type A, 48.3% type B, 6.5% type C and 6.5% type D. Femoral tunnel were placed at 11 or 1 o’clock position in transtibial technique and placed 10 to 10:30 or 2 to 2:30 o’clock position in technique using anteromedial portal. Radiographic analysis for degenerative arthritis revealed that in group using anteromedial tunnel, 50.0% were excellent, 25.0% were good. In group using transtibial tunnel 18.2% were excellent, 18.2% were good.
Conclusion: More than 87.1% of cases, long term result of the ACL reconstruction showed good and excellent result in IKDC score. Especially, the group using tunnel through anteromedial portal showed good results for degenerative arthritis.
