Reevaluation: The Most likely possibilities are that you have ITB syndrome that has failed conservative care, or that the pain is coming from something else, such as a pinched nerve in the back. If you have not had one, an MRI of the lumbar spine as well as the hip itself would likely confirm the diagnosis. Don't hesitate to seek a second opinion to get a fresh set of eyes to look at you as well. ...Read more

I had tkr feb. 2012, had issues since, had bone scan monday, sept 9. Results were possible infection, loosening, or trauma. Please help me understand.

Osteomyelitis: A bone scan may only reveal metabolic/physiologic changes in the area and not yield a specific diagnosis, but is suggestive of infection, as is loosening of the tkr. If you are only seeing the orthopedist would strongly suggest you request a consult with an infectious diseases expert. This is potentially very serious and will require both to resolve the issue if it is infected. Go soon. Good luck. ...Read more

Can back pain come from having a tkr?

Can back pain come from having a tkr?

Yes: A tkr doesn't typically injure the back, but many lower extremity surgeries can "throw you out of whack". As a result of the altered gait (aka limp), it can result in back pain. Ask the surgeon who did the tkr, but I anticipate that the back pain will slowly get better as your gait improves. ...Read more

What causes patellofemoral pain syndrome after a tkr?

It depends....: On whether the patella was resurfaced. Some patients will still have pain if their patella was not resurfaced. They may have damaged cartilage on the knee cap that is rubbing against the implant. Unfortunately resurfacing the kneecap later often only helps about half the patients. Talk with your surgeon or get a second opinion. There may be something else going on like loosening or infection. ...Read more

When loosening of prothesis parts or wear down of plastic parts happen few years after tkr how are they treated?

When loosening of prothesis parts or wear down of plastic parts happen few years after tkr how are they treated?

Regular follow up: With regular follow up with your surgeon, wear of the plastic in the knee can be seen. When the wear is bad enough, the plastic can be changed out (tire change). If you wait until there is pain, then one of the metal parts might be loose, requiring a more involved replacement surgery (tire and wheel replacement, and some time realignment too). ...Read more

54 yrs old. Bilateral tkr 5 yrs ago. Active outdoors and at work, tibial plates loosening. Both pcl's have failed. What could cause be?

Couple possiblities: You are a younger person with knee replacements. One reason is you simply wore them out. With a cruciate retaining knee and now with tears of the PCL you are putting more strain across the implants as the ligament has failed. Could be that surgery was done poorly. Could be infection although less likely given bilateral failure. First two most probable. ...Read more

Arthrofibrosis: What you describe sounds like arthrofibrosis. This is a painful condition that develops after knee replacement from excessive scarring. Sometimes this condition may occur in isolation, but arthrofibrosis may also occur when there is failure of ingrowth of an uncemented prosthesis, lumbar radiculopathy, complex regional pain syndrome, or occult postoperative infection. Follow up with your doctor to rule out these other conditions. ...Read more

Why doI still have pain in my quads after 2 tkr, 8mths ago and 4mths ago. Have the same difficulty getting up from sitting as I did before surgery.

Therapy needed?!: After a TKR, and even more so after 2, the most important thing to do is to follow a good PT program. If you do that then pain should resolve though it may take a full year to get to your highest potential. Usually it should take about six weeks till you are sure you are better and feel happy you had surgery. If not, follow-up with your orthopedist. ...Read more
