Mr. F is a 38-year-old man who complains of aching pain in his knees when exercising or walking. He has noticed his knees feeling hard and tight. His history indicates he was involved in athletics in college but now has less time to exercise due to family and work responsibilities. Anti-inflammatory drugs and analgesics can help Mr. F manage his osteoarthritis pain by reducing inflammation and pain. Moderate, non-weight bearing exercise is recommended to maintain mobility and muscle strength without worsening his symptoms. With continued medication and exercise, Mr. F's prognosis is expected to be stable.
