All-inside ACL reconstruction is getting its position in orthopaedic surgery day by day. The main aim of all-inside ACL reconstruction is minimizing the surgical trauma. Its evolutional progress looks similar to classic ACL reconstruction although two basic concept remained steady: sockets, or half-tunnels, are drilled from inside-out on both the femur and tibia and (2) the graft is introduced into the knee through an arthroscopic portal. When we compare all-inside and classic ACL reconstruction, patients postoperative pain is significantly lower in all-inside group. Performing the surgery by using sockets instead of tunnels provides adequate bone stock and it is an advantages to surgeon performing double bundle ACL and/or PCL reconstruction, multi-ligament reconstruction surgeries, revision ACL surgeries and in ACL reconstruction cases accompanying high tibial osteotomies. Using single tendon decreases morbidity due to autograft usage and it has positive effects on knee kinematics with regard to double tendon usage. Additionally, in pediatric cases the results of All-inside all-epiphyseal ACL reconstruction are satisfactory. Although long learning curve of this techniques seems to be a disadvantage, clinical experience revealed that it has less surgical morbidity with regard to classic ACL reconstruction techniques. This makes allinside ACL reconstruction as a promising concept but still in the literature there are not enough randomized controlled clinical trials. We think that in the future randomized controlled clinical trials with greater series will help us more detailed understanding of all-inside ACL reconstruction.
