??The evaluation of hip implantation success remains one of the most relevant problems in the orthopedic field. There are several factors that can cause its failure, e.g.: aseptic loosening and dislocations of the prosthetic joint due to implant impingement. It is fundamental that the orthopaedist can evaluate, following a total hip arthroplasty, which may be the possible risk factors that would lead to dislocation, or in the worst cases, to implant failure. This thesis focuses on the use of augmented reality for orthopedic surgery support, specifically for the assessment of arthroscopic procedures involving the pelvis and femur area. To this end, an application intended to support the activity of the orthopaedist in the post-operative phase has been developed.
