I've had implants in both my knees and they have never stopped hurting since 1999. The muscle surrounding my left knee kind of just sloughs off to the left and hangs. I had therapy for six months and it just wouldn't work, so the Dr put me in the hospital and manipulated (cracked) the knee so there was range of motion. The right knee hurts every time I go up and down steps or bend it from a stretched out position. I've been back and forth with Drs and surgeons plus had arthroscopies and they can't find anything wrong except to blame the Fibro. I'm starting to believe they're right, but I'm so sick of the swelling, sharp pains, throbbing and burning on a daily basis I could cry. I usually even wind up limping, it gets so bad. Has anyone out there had any experience with surgeries or implants in a joint? Please share. Oh, I've also had a Laminectomy on L3 and have stenosis in 4 disks (Degerative Disk Disease). Drs also said all my pain could be from my back! Feedback please!
