Knee Joint Replacement (cont.)


Follow your orthopedist's recommended schedule of visits and physical therapy. If emergency problems arise, go to an emergency department and then follow up with your orthopedist. The emergency doctor may contact your orthopedist during your emergency department visit to discuss and coordinate care. He or she may take X-rays or blood tests to help with your evaluation.


Prevention involves proper use of the new joint.

  • You must follow the instructions given you in physical therapy.
  • People with an unsteady gait who have a total knee arthroplasty (TKA) should consider using a cane or walker.
  • You may be prescribed antibiotics if you have dental work or other surgery, although not all doctors uniformly endorse such antibiotic use.

Prognosis of Knee Joint Replacement

With proper care and rehabilitation, a total knee arthroplasty (TKA) may last 20 years or longer before you need a replacement. Most replaced knee joints continue to work 10 years after surgery.
