Hi , thanks for writing to HCM.
Total shoulder arthroplasty (TSA) is generally reserved for end stage osteoarthritis
of glenohumeral joint
, Severe Rheumatoid arthritis
, Post traumatic arthritis
etc. It is contraindicated in Rotator cuff tears and non functioning deltoid muscle.
I don't think you are a candidate for TSA. You can try the following measures to improve your condition -
* Activity modification and avoiding overhead activities
* Physiotherapy to strengthen the rotator cuff and scapular stabilising muscles
Hope this information is helpful. Good day
