Good morning doctor! I have had joint pain in my right knee for almost 4 years, as a result of a sports injury. The joint feels stiff, it shifts out of position if you tread it (the pain is unbearable), and you only need to stand using one left leg because the knee on the right leg feels uncomfortable. Several months ago I consulted a bone doctor (orthopedist), the doctor said, 80% of the muscles were broken. To be sure, the doctor advised me to do an MRI. Until now, I haven’t done the MRI. My question is, do these symptoms (which my knee is experiencing) include calcification? and is there any solution other than surgery if that is what the doctor said about my knee (there is a broken tendon and it needs grafting). I ask for an explanation. Thank you for your attention.
