Revision arthroplasty is a procedure to revise or replace a previous knee replacement.

Why do some knee replacements fail?

The common reasons for a failed knee replacement include -

  • loosening - usually from degradation of the cement and/or wear of the plastic component. Bits of plastic may further lead to an immune response and lysis (dissolving away) of bone
  • infection
  • stiffness from arthrofibrosis
  • instability
  • bone breaks
