s very important to work closely with your doctor (preferably an orthopedic doc for
OA)
in regards to PT, medication and other therapies and also work very closely with them in monitoring when/if the pain and limitation of movement, strength, etc., interfere enough in your daily life to warrant a major surgery.
It's impossible to tell you what the operation would entail as it depends on the type of operation you might need and which joint/s it encompasses.
Best of luck.
