COMPARISION OF THE CLINICAL OUTCOME OF SINGLE AND DOUBLE-BUNDLE ACL RECONTRUCTION USING HAMSTRING TENDON AUTOGRAFT IN 198 HOSPITAL
Main Article Content
Abstract
Objectives: The aim of this study was to prospectively compare the clinical results of single- and double-bundle ACL reconstruction. Subjects and methods: A Non-randomized controlled clinical trial, prospective, cross-sectional study of 85 patients with indication for ACL reconstruction. 42 patients with the diameter of the gracilis graft was greater than 5 mm, and semitendinosus graft greater than 6.5 mm indication for double-bundle (DB) reconstruction. 43 patients with the smaller tendon diameters were reconstructed using a single-bundle (SB) technique. Results: All the patients reached a minimum follow-up of 2 years. No differences between the 2 groups were observed in terms of Lysholm score. The rehabilitation of sports activity Cincinnati scores showed statistically significantly in the DB group than in the SB group. The incidence of a residual pivot-shift glide was better in DB than in SB. Revision was performed in 3 of 43 patients in the SB group with grafts 7 mm or less in diameter. Conclusion: In the 2-year minimum follow-up, DB ACL reconstructions showed better anterior knee laxity and pivot-shift glide. The rehabilitation of sports activity Cincinnati scores, DB ACL reconstructions showed better than SB. However, longer follow-up and accurate instrumented in vivo rotational stability assessment are needed.
