What is a Revision Knee Replacement?
In specific circumstances, a patient who previously underwent total hip arthroplasty may need another surgery. A revision hip replacement involves removing any problematic implants and replacing them with new ones.
What Are the Indications for Revision Knee Replacement?
Revision knee replacement may be indicated for a variety of reasons. These include, but are not limited to, infection of the prosthesis, instability, fracture, implant loosening, wear of the bearing surface, or poor position of the knee replacement components. Dr. Phillips will evaluate your problematic knee replacement and use physical examination, laboratory testing and imaging studies to identify the issue prior to proceeding with treatment.
What Should I Expect During a Revision Knee Replacement?
Surgery is typically performed under general anesthesia. The time it takes to perform the surgery is dictated by the complexity of the problem. After the approach is complete, the problematic implants are removed from the knee. Attention is then turned to treating the issue at hand and reconstructing your knee joint. Robotic and/or image guidance technology may be utilized to ensure accurate implant positioning, appropriate ligament tension and full range of motion. Once all components are in place the incision is closed with a dissolvable suture beneath the skin when possible.
What is the Postoperative Course After a Revision Knee Replacement?
Depending on the complexity of the procedure, you may have a weight bearing or range of motion restriction after surgery. The majority of patients remain in the hospital overnight prior to being discharged home after a major revision knee replacement surgery. Outpatient physical therapy is crucial for rehabilitation and may be as frequent as 3 times per week for a minimum of 12 weeks. By 12 weeks, most patients are well recovered and beginning to return to more rigorous activities. However, small gains can be made out to the 1 year mark when full recovery has occurred.
