“…A major cause for concern with the use of hamstring autografts is, the soft tissue can take up to 12 weeks to heal to the osseous tunnel. 3,4 Thus, a secure fixation technique is needed to withstand the forces on the graft resulting from current rehabilitation protocols that allow for unrestricted ROM, weight bearing, and early return to athletic activity after ACL reconstruction. 3,5 The purpose of our study was twofold: (1) to investigate whether there is any difference in functional outcomes with these fixation methods as measured by the Lysholm knee score and (2) to determine whether there is a difference in the tunnel widening with joint line fixation using interference screws (aperture fixation) versus EndoButton (suspensary fixation) of hamstring autografts in ACL reconstruction and does it affect the functional outcome.…”

Background: Arthroscopically aided anterior cruciate ligament reconstruction using hamstring graft can be fixed to femoral condyle by suspensory and aperture fixation methods. The following study was undertaken to investigate whether there is any difference in functional outcomes with these fixation methods as measured by the Lysholm knee score and to determine tunnel widening post operatively with these two methods and does it affect the functional outcome.Methods: 50 patients of clinically and radiologic ally diagnosed ACL tear fulfilling the inclusion and exclusion criteria were randomized into two groups to undergo arthroscopic ACL reconstruction using quadrupled hamstring graft with suspensory (n=25) and aperture (n=25) fixation methods on femoral side. They were compared post operatively with Lysholm score, clinical laxity tests and percentage of tunnel enlargement using computed tomograms at 01 year.Results: At the end of 6 months there was no much difference in Lysholm score between both the groups (P =0.663) and at the end of 01 year aperture group had slightly better outcome. However, the difference was not statistically significant (p =0.173). There was more tunnel widening in the suspensory group especially of the femoral tunnel in the coronal plane. However, the amount of tunnel widening in both the groups was not significant statistically (P =0.071 and P =0.963). Tunnel widening is not associated with inferior clinical outcomes or functional knee score.Conclusions: Aperture and Suspensory fixation methods of hamstring graft at femoral condyle in ACL reconstruction are comparable clinically and there is no advantage of one particular method over other. Although comparatively more tunnel widening is seen in suspensory fixation methods; it does not affect the final clinical outcomes or functional knee scores.

“…Moreover, distal suspensory fixation could induce the "bungee cord effect" or "windshield-wiper effect" and lead to tunnel enlargement during the transition from flexion to extension. (Hoher, et al, 1998, Schultz, et al, 2007 Previous studies indicated that increased length between ACL fixation points may decrease stiffness and increase displacement during cyclic loading (Scheffler, et al, 2002) which results in decreasing the knee (Ishibashi, et al, 1997). Therefore, the lower laxity of knees repaired using SSSAS compared to the Pull-Out technique in the present study may be the result of decreased length between the fixation point and the tibial insertion site.…”

ÁvadasDël maþesnës donorinës vietos sindromo tikimybës vis daþniau priekinio kryþminio raiðèio (PKR) rekonstrukcijos operacijos sportininkams atliekamos panaudojant ðlaunies lenkiamøjø sausgysliø transplantatus, kurie fiksuojami tirpiaisiais sraigtais viename arba dviejuose kaulo kanaluose (1-4). Kryþminio raiðèio transplantà fiksuojant viename kanale, atliekama vieno pluoðto, o fiksuojant dviejuose kanaluose -dviejø pluoðtø rekonstrukcija.
