Abstract: | 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. |
