Abstract :
Introduction The knee is the most commonly affected joint in the
pigmented villonodular synovitis (PVNS). If misdiagnosed or mismanaged,
PVNS, especially the diffused form can destroy joints and can result in
terminal degenerative joint disease. Case Presentation We report 3 cases
of diffuse form of PVNS with grade 3 osteoarhtritis that IS treated by
total synovectomy and total knee arthroplasty (TKA). The mean duration
of the follow-up was 46.5 (9, 11, 120) months. In 2 cases, staged
posterior then anterior synovectomy and TKA were done with excellent
results. In 1 case, simultaneous synovectomy and TKA was performed with
hematoma formation postoperatively and quadriceps tendon rupture 10
weeks later with fair final result. Conclusions TKA in PVNS is a
challenging procedure. We recommend open posterior synovectomy then
anterior synovectomy and TKA in 2 separate operations. Quadriceps
mechanism must be protected during synovectomy.
