Primary arthroscopic synovectomy for pigmented villo-nodular synovitis of the knee: Recurrence rate and functional outcomes after a mean follow-up of seven years

Abstract

Primary arthroscopic synovectomy ensures satisfactory control of PVNS while preserving knee function. A full recovery remains possible even in patients with diffuse disease. In the event of a recurrence, open synovectomy can be performed.

Multifocal pigmented villonodular synovitis coexisting in both the knee joint and the patella: a case report and literature review

“…Localized type is generally indolent, but the diffuse type is more aggressive. Localized type is with a minimal rate of recurrence after removal, but diffuse type is a highly recurrent form with the capacity of eroding adjacent bone and soft tissue [11, 21]. The knee was reported the most affected joint accounting for up to approximately 75% of the cases of diffuse type [1, 21].…”

“…Arthroscopic synovectomy was done using standard anterolateral, anteromedial and posteromedial portals to ensure maximum removal of affected synovium [10, 11]. Dark brown bloody fluid drained from the joint with introduction of arthroscopy cannula.…”

Medical arthroscopy: A tool for diagnosis and research in rheumatology

“…Pigmented villonodular synovitis is nodular, prolific, dense, having a reddish‐brown or even orange color . Hemophilic arthropathy can show extensive articular destruction with hemosiderin‐stained synovium.…”

“…22 Pigmented villonodular synovitis is nodular, prolific, dense, having a reddish-brown or even orange color. 24 Hemophilic arthropathy can show extensive articular destruction with hemosiderin-stained synovium. Synovial chondromatosis is characterized by multiple cartilaginous bodies that are free within the joint.…”

Alta recidiva y buenos resultados funcionales tras la resección artroscópica de la sinovitis villonodular pigmentaria de la rodilla

“…En la presente investigación también observamos una mejoría funcional en dicha escala que pasó de 47,8 a 78,4 puntos. De forma similar, en el estudio de Auregan et al21 evidenciaron buenos resultados funcionales y niveles de actividad con mejoras significativas sin encontrar tampoco diferencias entre SVPL y SVPD.Una de las peores consecuencias de la SVP son los cambios degenerativos precoces en pacientes por otro lado sanos y jóvenes. Flandy et al4 reportaron un 48% de cambios degenerativos avanzados posterior a la realización de una sinovectomía abierta.…”
