Revision Knee Replacement Surgery
Though total knee replacement surgery contributes a 90% success rate, knee replacements tend to deteriorate due to many reasons. One of the major reasons is infections in the knee. Proper administration of antibiotics lessens the infection but in a period, it leads to aseptic loosening may lead to pain and bone loss. In that case, revision knee replacement surgery is performed. Surgeons scrupulously remove the previous prosthesis and implant a new prosthesis. Knee revision requires proper preoperative planning, mastery of surgical skills, state of the art implants and prolonged operative time.
Who needs knee revision replacement?
Patients suffer from failed prosthetic knee implants because of infections, injury, stiffness, instability and wear and tear.
Artificial knee replacements suffice in elderly patients, but for someone who owes an active lifestyle knee prosthesis fails should be treated by knee revision replacement surgeries.
How is it performed?
- After anaesthetic evaluation, the team ascertains the type of anaesthesia that needs to be administered i.e., general anaesthesia / spinal, epidural or regional nerve block anaesthesia.
- The surgeon makes incisions in the knee to primarily remove the old components and moves the knee cap and tendons aside to limelight the knee joint.
- The doctor examines soft tissues to confirm that they are free from infection and assess every prosthetic part (metal/plastic) for its efficiency.
- To preserve bones, if necessary surgeon might remove the original implant or cement. This procedure is complex and done by the masters in the field.
- The surgeon prepares bones surfaces for newer implants and inserts the specialized implant to repair the tissues if they have been damaged during the surgery and meticulously test the motion of the joint.
- After the procedure, the surgeon closes up the incision and bandages the knee.
- Post-surgery, depending on the damage and the procedure done to rectify it, the patient might be discharged the same day or the next day.
- Subsequently, the doctor may suggest an exercise regimen to follow at home or recommend physiotherapy. The exercises are necessary to help restore the full range of motion and strengthen the surrounding muscles.
