TKA Aseptic Loosening is an inflammatory response that results in bone loss and eventual implant loosening. Diagnosis is made with knee x-rays.
.
Steps in process of #AsepticLoosening: small particle debris formation - inflammatory response - osteolysis - implant micromotion/loosening
(implant-cement interface is most common "weak link" vs bone-cement interface)
.
TKA Aseptic Loosening X-ray Findings:
- tibia osteolysis (bone breakdown)
- femoral osteolysis
- radiolucent area around implant/cement with sclerotic border (especially greater than 2mm)
- change in implant position (varus/valgus tibial component alignment)
- progressive widening of cement-bone or bone-prosthesis interface
.
Treatment Options
- Nonoperative observation (for stable implant with minimal symptoms)
- Operative #KneeReplacementRevision
.
