<s>[INST] I m having severe pain in my knee joints and the pain is more while climbing up and down a staircase. there is also cracking sound when i stretch and bend the knees. i m unable to put load on my knees while getting up from a chair or floor. kindly suggest what needs to be done to relieve the pain and walk normally [/INST] Hello, The symptoms are suggestive of a condition called locked knee. It is due to entrapment of minor objects in the knee joint. Consult an orthopedician and plan for an MRI scan. Sometimes you might require an arthroscopic repair. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Shinas Hussain, General & Family Physician </s>
