Revision knee replacement surgery may be done for a loosening of the knee implant, for infection in the artificial knee joint, for a fracture surrounding the artificial knee joint that has led to a loosening of the knee joint, or for a patella that is dislocating.
There are different types of revision surgery. In some cases, only one implant or component of the prosthesis has to be revised. Other times, all three components (femoral, tibial, and patellar) need to removed or replaced and the bone around the knee needs to be rebuilt with augments (metal pieces that substitute for missing bone) or bone graft.
The cost of Revision Knee Replacement varies from 3000 to 4000$ USD. The cost of Revision total knee replacement depends on the type of prosthesis need to replace. The cost also depends on the type of facility that you approach for the procedure.
Infection in the knee replacement can happen suddenly or over an insidious onset. Sudden infection in the artificial knee will manifest as a sudden increase in pain, inability to bear weight, swelling and redness of the knee, and also may be manifested as a spike in fever. Insidious onset in the knee replacement will manifest as slowly increasing pain, redness and swelling. The patient, especially if immunocompromised, may not have a spike in fever.
The most common reason for kneecap to dislocate after primary knee replacement surgery is that the femoral implant is not aligned correctly in the right rotation on the thighbone.
The way to resolve it is, unfortunately, revision knee surgery in which the femoral component has to be removed and replaced correctly in correct rotation. Generally, most knee revisions typically need replacement of all three components of the knee joint, the femoral component, the tibial component, as well as the plastic that is between the femoral and the tibial component.
A septic loosening is loosening at the interface of the implant and the bone, or it could be loosening at the interface between the cement and the bone. With time, there is wear of the plastic, and the plastic can eat into the bone causing osteolysis. If the osteolysis is significant, implant fixation is compromised and required revision surgery.
Most of the surgery is performed in a bloodless manner, however certain types of knee revision surgeries require that the procedure is done over several hours. In these types of surgeries, there may be intraoperative blood loss, which may need a blood transfusion.
You should experience a significant reduction in pain and improved mobility after knee replacement surgery. Many factors, including physical condition, weight, activity level, personal anatomy and willingness to comply with your surgeon’s instructions prior to and after surgery will play an important role in your recovery.
Recovery from knee replacement revision surgery is typically longer than a primary knee replacement surgery and depends on what was done during the knee replacement surgery.
The life of revision knee surgery depends on what was performed during the procedure, the quality of the bone, and the fixation of the implant.
