Revision arthroplasty: Placement of new component(s) following removal of failed implant
Wide spectrum of revision
Small changes may not be obvious
Exchange of polyethylene component
Change of femoral head (modular; may be changed without extracting stem)
Larger changes of entire components
Some revisions have implications related to substantial bone loss: Large defects to fill, little bone to support arthroplasty
Loose components may fracture and lyse large regions of bone
Infection may destroy bone
Particle disease with massive osteolysis leaves osseous defects
Imaging evaluation required both pre-op and post-op
Preop: Evaluation of bone stock for surgical planning
Postop: Evaluation for complications
