Shoulder anatomy joints

In general, the success rate of TSR exceeds 90% for a wide range of common shoulder problems. As in THA and TKA, the aim of TSA is to reduce pain, restore damaged anatomy, and restore function. As for hip and knee arthroplasty, there are continuing concerns about component fixation and persisting instability of the joint.
