Comparison of Tendon and Muscle-Tendon Semitendinosus Grafts After ACL Reconstruction
Sponsor: University Hospital Dubrava
Summary
Aim: Comparison of tendon to bone ingrowth in bone tunnels and intra-articular remodeling of the graft after anterior cruciate ligament surgery with a muscle-tendon graft and those with a tendon graft. Subjects and methods: It is a single-blind prospective randomized study that would include at least 40 patients with an anterior cruciate ligament rupture. Patients would be randomly divided into two groups of minimally 20 patients each. Patients in the first study group would undergo ACL reconstruction with a muscle-tendon graft, while patients in the control group would be treated with the standard method of ACL reconstruction with a tendon graft. Expected contribution to the field: The assumption is that the obtained results could enable a better understanding of the contribution of remaining muscle fibers on the tendon in anterior cruciate ligament reconstruction operations to the tendon to bone ingrowth and intra-articular remodeling of the graft of operated patients.

Interventions
ACL reconstruction
Participants will undergo arthroscopic all-inside anterior cruciate ligament reconstruction using an autologous semitendinosus graft. In the experimental intervention, a muscle-tendon semitendinosus graft is used, with preservation of muscle fibers on the tendon. In the control intervention, a standard tendon-only semitendinosus graft is used. In both groups, graft preparation, tunnel creation, fixation technique, and concomitant lateral tenodesis are identical, and all procedures are performed by the same surgeon following a standardized protocol.
