Hi, thanks for writing to HCM. It looks like your mother is having degenerative arthritis of knee. An xray of the involved knee diagnoses the condition and the severity of the wear and tear in the joint. The management of Degenerative joint disease is as follows - * PHYSICAL THERAPY : The mainstay of treatment in the early case is physical therapy, which should be directed at maintaining joint mobility and improving muscle strength. Other measures, such as massage and the application of warmth, may reduce pain. * LOAD REDUCTION : Protecting the joint from excessive load may slow down the rate of cartilage loss. It is also effective in relieving pain. Weight reduction for obese patients, wearing shock-absorbing shoes, avoiding activities like climbing stairs and using a walking stick are worthwhile. * ANALGESIC MEDICATION : Simple over the counter medications like acetaminophen is sufficient in most cases. If this fails to control pain, a non-steroidal anti-inflammatory drug may be better. * VISCOSUPPLEMENTATION: Hyaluronic acid injections given into the joint in prescribed dosages will give good short term relief in selected cases and helps in postponing total joint replacement surgery atleast for a year or two. * JOINT REPLACEMENT : Joint replacement is nowadays the procedure of choice for osteoarthritis in patients with intolerable symptoms, marked loss of function and severe restriction of daily activities. Hope this information is helpful. Good day
