Comparison of Clinical Results and Second-Look Arthroscopic Findings of Remnant Preserving versus Non-Remnant Preserving Technique after Anterior Cruciate Ligament Reconstruction Using Achilles Allograft / 대한정형외과학회잡지

ABSTRACT

PURPOSE: This study was conducted for evaluation of clinical uses of anterior cruciate ligament (ACL) reconstruction with an Achilles allograft using the remnant technique by comparison and analysis stability, functional assessment and results of second-look arthroscopy between the remnant technique and the non-remnanat technique. MATERIALS AND METHODS: A total of 48 patients who underwent ACL reconstruction using an Achilles allograft were selected and divided into two groups depending on the presence of remnant. The preserving group included 26 patients and non-preserving group included 22 patients. The two groups were compared and analyzed with regarding to stability (Stress view Lachman test, pivot shift test), functional assessment (International Knee Documentation Committee, Lysholm score, Tegner score, single hoop test, shuttle turn, carioca test), and the result of second-look arthroscopy (study design: prosepective cohort study). RESULTS: In the final result, the remnant group showed significant improvement in the Tegner and carioca tests compared with the non-remnant group (p<0.05). In second-look arthroscopy, the remnant group showed better coverage of synovium (p<0.05). CONCLUSION: ACL reconstruction with an Achilles allograft using the remnant technique showed better results in functional assessment and finding in second-look arthroscopy compared with the non-remnant technique group.
