Revision Total Knee Replacement

Revision Total Knee Replacement

Although total knee replacement is one of the most successful procedures that gives a pain-free and active lifestyle to the patient, but sometimes the procedure may fail due to a variety of reasons like implant wear and loosening. Failure of total knee replacement procedure may lead to pain, stiffness, instability and swelling of the new joint making it difficult for the patient to perform their everyday activities. In such cases, the surgeon generally recommends a second surgery or revision total replacement surgery to remove some or all of the parts of the original prosthesis and replace them with new ones.

How is revision surgery different from primary Total knee replacement surgery?

Although both the procedures have the same goal of pain relief and improved functioning of the joint but still both the procedures are different. The revision surgery is generally a longer and more complex procedure that requires extensive planning, and specialized tools and implants with longer, thicker stems that fit deeper inside the bone for extra support tools to achieve a good result. Revision surgery is of following types:

  • Revision of only one implant or component of the prosthesis

  • Revision of all three components i.e. femoral, tibial, and patellar

  • Rebuilding of the bone around the knee with augments or bone graft

Indications for revision Total knee replacement

  • Loosened implant from the underlying bone, causing the knee to become painful

  • Plastic (polyethylene) wear & tear of the new implant or adjoining tissues and cartilages

  • Infection due to complication from the surgical procedure

  • Unstable knee due to damaged or improperly balanced ligaments around knee

  • Development of extensive scar tissue that limits the range of motion

  • A periprosthetic fracture around the components of replaced knee due to fall

  • Osteolysis (bone loss) due to release of particles into the knee joint resulting in bone being destroyed
