Total hip and knee replacements can provide long-term relief from arthritis and other forms of severe joint damage. Over time, however, an artificial joint can wear, loosen, become unstable, develop an infection or experience another complication. When a previous joint replacement no longer functions properly, total joint revision surgery may be needed.

Revision surgery involves removing and replacing some or all components of an existing total hip or total knee replacement. Because revision procedures often involve changes to the surrounding bone and soft tissues, they can be more complex than the original joint replacement.

Who Needs It

Revision surgery may be considered for patients experiencing a Failed Joint Replacement due to implant loosening or wear, instability, recurrent dislocation, fracture around an implant, significant bone loss or other mechanical problems.

A Joint Replacement Infection can also require revision surgery. Depending on the type and duration of the infection, treatment may involve replacing the implant during one procedure or removing it and performing the revision in stages.

Not every painful hip or knee replacement requires revision. Determining the source of the symptoms through a thorough evaluation is essential before surgery is recommended.

How Does It Work

Revision surgery is tailored to the problem affecting the original replacement. The surgeon may remove one component, several components or the entire existing implant. Damaged bone and soft tissues are evaluated, and specialized revision implants may be used to restore stability and joint function.

When bone loss is present, additional techniques or implants may be necessary to provide adequate support. For infection-related revision, the procedure also focuses on removing infected tissue and treating the underlying infection. Detailed preoperative imaging and testing help the surgeon determine the appropriate approach.
