Double bundle acl repair system

a double bundle and acl technology, applied in the field of anterior cruciate ligament (acl) repair surgery, can solve the problems of increasing the stiffness of the graft, the inability of the ligament to stabilize the knee joint, and the inferior strength and stiffness at 4 weeks compared with cortical fixation, so as to facilitate the tensioning of the pl bundle and facilitate the separation of the graft bundles

Abstract

A system for single tunnel, double bundle anterior cruciate ligament reconstruction includes implant constructs and instruments. The implant constructs provide a combination of cortical fixation and bone tunnel aperture fixation. The implant constructs separate a graft into distinct bundles. The instruments are used to prepare shaped bone tunnels to receive the implant constructs and graft bundles. Methods for reconstructing the antero-medial and postero-lateral bundles of the anterior cruciate ligament may rely on single femoral and tibial tunnels and a single strand of graft.
