<s>[INST] hi dear, patient age is 57 and suffering severe pain in knees, local consultant say, this is due to nee gap, at present patient is unable to walk, just below left knee,it is serious pain when try to walk. kindly, suggest treatment other than surgery like giving injection or some thing else. [/INST] Hello, The symptoms are consistent with osteoarthritis. Surgical correction in the form of knee replacement will be the best option. You can also try steroid injection to the joint cavity and it will provide long term pain relief. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr. Shinas Hussain, General & Family physician </s>
