Reverse shoulder replacement is a commonly performed procedure for patients with shoulder osteoarthritis, rotator cuff tear, cuff tear arthropathy, neglected dislocation, or proximal humerus fractures. In this procedure, normal anatomical orientation of the ball and socket joint is reversed to socket and ball orientation  providing satisfactory function in a rotator cuff deficient shoulder.  Your surgeon will remove both parts of the joint and replace them with artificial implants consisting of metal (combination of titanium and cobalt chrome) and polyethylene. Following rehabilitation using a sling for the first few weeks, followed by physiotherapy, you are expected to regain normal function in approximately three months. A shoulder replacement lasts for more than 10 years in 95% of patients. Once the implant loses its function, it is revised with newer implants (Revision shoulder replacement) to maintain shoulder function.
