I had right TKR almost 3 years ago. No major problems, except permanent clicking noise with some motions. Had Arthritis, bone spur, torn Meniscus a year prior to TKR. Repair surgery with intense PT and exercise regimen after that did not change the pain. Would have been ok if I did not plan on living an active life, but every time I walked down an incline, or steps, intense pain. So TKR. After the usual course of pain/rehab/continued exercises the knee works very well. For me the surgery was worth it. Well, except for the well known kneeling issue. As in don’t do it.
