Arthroscopic evaluation of ACL grafts reconstructed with the anatomical two-bundle technique using hamstring tendon autograft.
This article describes second-look arthroscopic evaluation of the transplanted grafts after anatomical two-bundle ACL reconstruction, which had been performed between December 2000 and March 2004. Using two double-looped semitendinosus tendon grafts via separate femoral and tibial tunnels in the anatomical ACL footprints, 65 patients (mean age of 24 years) underwent anatomical two-bundle ACL reconstruction. The evaluation was performed for those who had undergone the procedure 5-29 months (mean 16.5) previously, with emphasis on graft tension and the presence of graft damage by meticulous probing. None of the anteromedial (AM) grafts showed rupture, while 11% of the posterolateral (PL) grafts showed substantial damage around the femoral tunnel aperture. Both the AM and PL grafts were evaluated as lax without apparent graft rupture in 9% of the knees. These results suggest that the currently performed anatomical two-bundle ACL reconstruction and postoperative regimen still remain to be improved to achieve better postoperative graft morphology.
