Hi...it’s been a while since I’ve posted here.. Something has cropped up with my left knee...it’s been going pretty good with it since the revision in August 2016 but the past three weeks or so I’ve been getting some very sharp stabbing pains on the anterior side and just under the patella. It happens sometimes when I am putting pressure on it from walking, no matter the surface. I never know when it’s going to happen but when it does it’s a very sharp stabbing pain that’s an immediate 10/10. Then it’ll happen with every step for a while, it stops when it stops sort of thing. I’m going for another surgery on my right knee soon to have the patella resurfaced, some adhesions removed and a possible femoral joint replacement. This with the left knee has me worried for the reason it’s not getting any less frequent and with the upcoming surgery. My surgeon told me he is done with my left knee, he’s not doing anything else with it. Anyways, any suggestions as to what anyone thinks is going on will be appreciated.
