Knee Replacement

Trey Cui, MD, discusses total knee replacements.

Knee replacement, also called arthroplasty, is a surgical procedure to replace a knee damaged by disease or injury.

Knee replacement surgery is most often done to:

  • Ease knee pain and disability due to arthritis or previous severe knee injury
  • Correct a knee deformity

Recovery may take several weeks to months depending on your overall health.
