A rare case of extensive diffuse nonpigmented villonodular synovitis as a cause of total knee arthroplasty failure

Abstract: INTRODUCTIONNonpigmented villonodular synovitis (non-PVNS) is a benign proliferative disease involving the synovium. It is a rare condition that is little recognized. Non-PVNS has been reported as a cause of total knee replacement failure.PRESENTATION OF CASEWe report a case of extensive diffuse non-PVNS in a patient with tibial component loosening after total knee replacement and review the related literature.DISCUSSIONIt is reported that pigmented villonodular synovitis (PVNS) occurs less frequently than non… Show more

“…Tosun et al. [15] reported a case of spontaneous diffuse non-PVNS, which presented in similar timeline to our patient roughly 4 years after surgery. Their patient had no evidence of recurrence in symptoms 6 months after revision surgery and synovectomy [16] .…”

“…There was no significant difference in anemic rate before surgery, and only one patient in the periarticular cocktail injection group received blood transfusion after surgery; also, the rates of wound infection and DVT were not increased in the subperiosteal cocktail injection group, which meant that this technique could reduce blood loss without increasing complications [33,34]. Otherwise, the reduced blood loss would also be helpful to decrease the prosthesis loosening rate [35][36][37].…”

“…Treatment options for SAK are different from the type of infections. For acute knee infections, arthroscopic surgery is currently used [1]; for chronic joint infections or osteomyelitis, knee debridement is more suitable [5]; for periprosthetic joint infections, the generally accepted treatment is two-stage revision surgery [17][18][19]. However, for SAK, there is still no unified treatment strategy, and it is very challenging [20][21][22].…”
