Abstract

PURPOSE: In order to know the clinical usefulness of the Bioscrew(Linvatec, USA) and the Semi-Fix (Arthrex, USA) technique for femoral fixation in ACL reconstruction using hamstring double loops, we scrutinized and compared the 24 knees. Materials and Methods: We compared Lysholm score, Hospital for Special Surgery(HSS) knee rating scores, Lachman tests, Pivot-Shift tests and KT side to side difference in 24 knees after arthroscopic ACL reconstruction using hamstring double loops from August 1996 to January 1998. We have used fourteen bio-absorbable interference screws and ten Semi-fixs for femoral tunnel fixation. RESULTS: We took the data; the Lysholm score of 96.1 and 94.1; HSS score of 98.6 and 98.1; KT differ- ence of 1.3 +- 2.13(mm) and 1.2 +- 1.89(mm) after ACL reconstruction using Bioscrew or Semi-Fix respec- tively. Femoral tunnel enlargement showed 2.51 +- 1.03(mm) and 1.95 +- 2.33(mm) respectively. And we got the similar results of Pivot-shift test, Lachman test and anterior drawer test after reconstructive surgery. CONCLUSION: Since we got the similar good data in comparative clinical study between the Bioscrews and the Semi-Fix technique, we anticipatd that either the use of Semi-fix technique or the biodegradable interference screws would be bright in the fixation to femoral tunnel in ACL reconstruction using ham- string double loops.
