At each assessment interval, information on complications and adverse events will be collected. In addition, shoulder joint range of motion will be collected, and implants will be evaluated radiographically to determine joint position and assess implant with regards to radiolucencies, subsidence and subluxation (migration). Patient satisfaction with regard to the effect of the implant on shoulder function, joint pain, and overall satisfaction will be assessed using a visual analog scale (VAS). Furthermore, if there are any implant revisions during the 10-year follow-up for any of the patients enrolled in the study, the implant and/or surrounding tissue will be harvested if possible and submitted for histopathological examination.
