I ve been having severe right knee pain since October. Have gone to PT and also do some some exercises at home but most of my pain continues behind my knee, right outer side and sometimes my knee cap. Sometimes I have difficulty walking but for the most part bending it and going down the steps is excruciating. The MRI showed a lot degeneration and a slight ligament tear but sports doctor says it s not miniscus. I had a steriod shot but relief only lasted 2 weeks and I mcontemplating the consecutive shots which will lubricate my joints but might not due the expense I would incur out of pocket. I m now considering a surgical procedure to scrape and clean the area....I forgot what the process is called....in hopes it would alleviate the pain and hlp me have a normal life again. Any thoughts or recommendations on that procedure?
