Description
Summary:Pigmented Villonodular Synovitis (PVNS) of knee joint is a rare disorder of Synovium. Hip and knee joint are commonly affected joints. The knee PVNS presents as a localized or diffuse form. Diagnosis if often delayed and permanent joint damage occurs with advanced disease. Ultrasound examination shows fluid collection and synovial hypertrophy. Magnetic resonance imaging helps in clinching the diagnosis. Final confirmation of PVNS is done with histopathological examination of synovial tissue removed. Post operative radiation has shown to reduce the rate of recurrent disease. 25 years male presented to us with painless swelling of left knee joint of 3 months duration. Radiographs were normal. MRI showed synovial hypertrophy with changes suggestive of PVNS. We did arthroscopic six portal synovectomy. The patient regained his function and was asymptomatic at 2 year follow up. We want to emphasize that early diagnosis and well done arthroscopic Synovectomy gives good clinical outcome with low recurrence rate. Radiotherapy should be reserved for recurrent disease.
