Simple cyst, enchondroma, and fibrous dysplasia can mimic each other and can be hard to distinguish. The prevalence of deep infection after TKA is approximately 0.42.0% [17]. With very sensitive pulse sequences such as STIR (short-tau inversion recovery), subtle extension across the physeal plate may be seen not uncommonly. What does unremarkable study in xray means? Asymmetric extension instability is much more common than symmetric extension instability. Lesion size as measured on plain films will not tell us this accurately if anything, it tends to greatly underestimate the extent of the lesion. Whereas CT can be useful for assessing the extent of osteolysis [38], evidence suggests that MRI with metal artifact reduction technique can show the granulomatous tissue caused by the wear particles and capture synovitis before discernible bone loss occurs [39, 40].
