Preventing Infection After Joint Replacement Surgery

One of the most serious complications facing patients who undergo joint replacement surgery is infection. Although infection occurs in only a small percentage of patients, it can prolong or limit full recovery.

Infection may occur in the wound or deep around the prosthesis. It may happen while in the hospital or after you go home. It may even occur years later. Any infection in your body can spread to your joint replacement.

Minor infections in the wound area are generally treated with antibiotics. Major or deep infections may require more surgery and removal of the prosthesis.

Discuss your concerns thoroughly with your orthopaedic surgeon prior to surgery.

This video provides additional information about infection and its prevention.

  • Shaking chills
