1. A medical implant (1), comprising
at least a first cortical fixation device (200) for fixing a ligament or tendon graft (G) in a desired position, wherein the at least first cortical fixation device (200) comprises a body (201) having a front side (201a) and a rear side (201b), which rear side (201b) faces away from the front side (201a), and wherein the body (201) comprises a first and an adjacent second through-hole (210, 211), which through-holes (210, 211) extend from the front side (201a) to the rear side (201b) of the body,
wherein
the medical implant (1) further comprises a first suture thread (100) extending through the through-holes (210, 211) and comprising a twisted loop (104) and a non-twisted loop (105) on the front side (201a) of the body (201), and a sliding knot (108) on the rear side (201b) of the body (201), and wherein the medical implant (1) comprises a second suture thread (300) extending through the sliding knot (108), and wherein the second suture thread (300) is configured to bring the sliding knot (108) away from the cortical fixation device (200) so as to loosen the twisted and non-twisted loop (104, 105), wherein the front side (201a) of the body (201) comprises a slot (202) that accommodates the first suture thread (100), wherein the slot (202) extends from the first through-hole (210) to the second through-hole (211), and wherein the slot provides a knot-free fixation of the first suture thread (100) in the slot (202) by clamping two portions (120, 121) of the first suture thread (100) accommodated side by side in the slot (202).
