Thanks for posting your query,
Although it isn't possible to diagnose your condition without an examination and a few tests, your history is suggestive of osteoarthritis
knee. Often called wear-and-tear arthritis, osteoarthritis occurs when the protective cartilage
on the ends of your bones wears down over time. Osteoarthritis treatments can slow the progression of the disease, relieve pain and improve joint function.
I would suggest getting this evaluated by an orthopedician for detailed examination. You may get the X-ray, some blood tests and joint fluid analysis under his/her guidance to reach the accurate diagnosis.
I hope this information has been both
informative and helpful
