Thanks for contacting with your health concern
1. As you are a diagnosed case of
arthritis and under the supervision of your physician thus remain under his regular guidance and follow up as he must be knowing all your case history and symptoms and since I'm unable to examine you directly, I at most can let you know about the symptomwise approach:
i. Rule out other causes of
knee pain like
tuberculosis, ask for Hb%,
WBC, ESR, RA test, X-ray Knee - AP & Lateral.
ii. As gone through
cortisone injection, remember that it should not be given repeatedly, as it may accelerate the process of articular destruction.
iii. If no response to routine treatment
. If knee is swollen, warm & tender.
. If there is wasting of quadriceps muscle, refer to an Orthopedic Surgeon [since he will be in better position to advise you regarding knee replacment]
