However, if arthritis is severe or symptoms are not well controlled with rest, medication and injections, a shoulder replacement may be recommended.

acromioclavicular joint arthritis

Acromioclavicular joint arthritis occurs where the collarbone (clavicleclavicleThe collarbone.) meets the shoulder blade (scapula) at the acromion. The most common symptoms are pain at the top of the shoulder, pain when crossing the arm in front of the body (such as reaching to touch the other shoulder) or pain when raising the arms above the head.

what can patients expect long term?

Osteoarthritis affects everyone differently. In some people, their arthritis progresses rapidly, with severe symptoms. This requires aggressive management of the disease. Fortunately, the development of new medications and innovations in joint preserving or joint replacement procedures are continuing.
