Revision knee replacement is a surgical procedure that is performed when a previous knee replacement surgery has failed or resulted in complications. In this procedure, the previous implant is removed, and a new implant is inserted. The goal of revision knee replacement is to restore function and relieve pain in patients who have had problems with their previous knee replacement.
Revision knee replacement is a more complex procedure than primary knee replacement because it requires the removal of the previous implant, which may have become firmly attached to the bone. This may require additional bone cutting and removal of more bone than in the original knee replacement. Additionally, revision knee replacements may require the use of specialized implants designed for revision surgery.
Revision knee replacement surgery may be necessary for a variety of reasons, including implant loosening, infection, wear and tear, instability, and implant fracture. Patients who experience persistent pain, stiffness, or other complications after knee replacement surgery should consult with their orthopedic surgeon to determine if revision surgery is necessary.
The recovery period for revision knee replacement is usually longer than for primary knee replacement surgery, and patients may need to use crutches or a walker for several weeks. Physical therapy is also an important part of the recovery process, as it helps to strengthen the knee and improve range of motion.
