Abstract:
Pigmented villonodular synovitis (PVNS) is a benign proliferative joint disease, which is a rare finding after total knee arthroplasty (TKA). There is currently no link between PVNS and TKA, and it has been described infrequently in the literature. Its presentation has varied along with the time that it presents postoperatively. We describe a case of a patient who presents with recurrent hemarthrosis 4 years after TKA. The patient had no previous history of PVNS and had an arthroscopy 1 year after the index operation with no evidence of synovitis. We present details of the first case with a review of imaging and pathology and a brief review of the literature on PVNS occurring after TKA.

z Scores and Unusual Values
This score indicates how far a value is from the mean in terms of standard deviation. For example, if a data value has a z score of +1, the researcher can infer that the particular data value is one standard deviation above the mean. If another data...
