What causes aseptic loosening of implants?
Aseptic loosening can be the result of inadequate initial fixation, mechanical loss of fixation over time, or biologic loss of fixation caused by particle-induced osteolysis around the implant.
How is aseptic loosening diagnosed?
The most accurate test for diagnosis of aseptic loosening in TKA was SPECT/CT arthrography demonstrated by the summary receiver operating characteristic curve. Conclusions: The best available evidence suggests the most accurate modality for the detection of aseptic loosening in TKA is SPECT/CT arthrography.

What is septic loosening?
According to the long-standing definition, septic and aseptic total joint replacement loosening are two distinct conditions with little in common.
