Prothesenwechsel

Prothesenwechsel, also known as revision arthroplasty, is a surgical procedure to replace a prosthetic joint that has become worn out or is causing problems. Artificial joints, such as hip or knee replacements, are designed to last for many years, but over time, the materials can degrade, the implant can loosen from the bone, or infection can occur. When these issues arise, a prothesenwechsel may be necessary.

The surgery involves removing the old implant and any damaged surrounding bone or tissue. A new prosthetic joint is then carefully implanted. The complexity of a prothesenwechsel can vary significantly depending on the reason for revision and the condition of the patient's bone. It is generally a more challenging procedure than the initial joint replacement due to the presence of scar tissue, altered anatomy, and potential bone loss.

Indications for a prothesenwechsel include aseptic loosening, where the implant detaches from the bone without infection; periprosthetic fracture, a break in the bone near the implant; infection of the prosthetic joint; instability of the joint; and significant pain or loss of function.

Recovery after a prothesenwechsel typically involves a longer rehabilitation period compared to a primary joint replacement. Patients often require physical therapy to regain strength, mobility, and function. The success of the revision surgery depends on factors such as the patient's overall health, the extent of bone loss, and the surgical technique employed. While revision arthroplasty aims to restore function and alleviate pain, the long-term outcomes can be more variable than with initial joint replacements.
