Fig. 5From: Using arthroscopy combined with fluoroscopic technique for accurate location of the bone tunnel entrance in chronic ankle instability treatmentImplantation of the tendon graft and fixation of the fibular side. The Keith needle with the PDS suture (2 polydioxanone suture) was passed through the bone tunnel a, Under arthroscopic visualization, the ENDOBUTTON plate and the folded side of Y-shaped tendon graft were introduced into the bone tunnel using the PDS suture b, c, and then the end of the tendon graft was pulled back to make sure the ENDOBUTTON plate attached to the posterior cortex of the fibula dBack to article page
