REVISION KNEE REPLACEMENT

A total knee joint replacement may need to be revised (changed) if it is causing significant symptoms.  This may be a result of infection, excessive wear, loosening, instability or pain.  Fortunately, this surgery is rarely required, occurring in only 4% of joints after 10 years. The operation is often complex with the extent of surgery depending on the severity of the underlying problem. 

 

Extensive investigation is required before considering revision surgery.  This usually includes blood tests to exclude infection, X-Ray imaging of the knee and both legs in entirety, and a bone scan. Once the issue is diagnosed, a plan is formulated to deal with the symptoms. 

What's involved?

  • A revision procedure involves removal of the problematic component/s within the joint, restoration of any bone defect and placement of a new implant

  • A temporary spacer and prolonged antibiotic treatment may be required before implantation, if there is evidence of infection

  • The length of stay in hospital can be variable

  • You may benefit from post-operative physiotherapy exercises

  • Your surgical incision will be reviewed 2 weeks after surgery
