O1171 COMPARATIVE ANALYSIS OF PRIMARY ANTERIOR CRUCIATE LIGAMENT PLASTY WITH ALLOGENIC AND AUTOGENIC BONE – PATELLAR TENDON – BONE GRAFT

Abstract

Aim: The aim of our study was to compare the results of primary ACL reconstruction, performed in our department with deep frozen allogenic BTB graft to the results with autogenic BTB graft. Patients and Method: From the 1st January, 1996 to 31st December, 2001 81 ACL reconstruction on 78 patients (17 female, 61 male) were performed. The average age of our patients was 25.6 years (14.5 – 46 years). There were 56 ACL plasties on 54 patients (13 female, 41 male) where allogenic BTB graft was used and 25 cases on 24 patients (4 female, 20 male) where autogenic BTB graft was used. The average follow up time was 37 months (12–82 months). All the surgeries were performed with arthroscopic technique. Results: We had the chance to follow up 46 knees of 44 patients in the allogenic group, and 20 knees of 21 patients in the group where autogenic BTB graft was used. The results were analysed with the help of the Lysholm, Tegner and IKDC scores. There were no significant differences found between the two groups according to these scores. In the group where allogenic BTB graft was used for the primary ACL plasty neither rejection of the graft nor immune synovitis were observed. Transmission of infectious diseases (hepatitis C, HIV, etc.) were not observed either. The cosmetic results were better (postoperative scar was smaller) and there where no donor site problems. Conclusion: Comparing our results using deep frozen BTB allogenic graft with the results after BTB autograft, we suggest the use of the allogenic BTB grafts in selected cases. It is proposed, because the results are relatively good and there where no specific complications found (e.g. rejection of the graft, immune synovitis etc.) for this type of graft.
