Total knee arthroplasty in pigmented villonodular synovitis: a case report and its management

Pigmented villonodular synovitis (PVNS) is a benign yet potentially aggressive proliferative lesion of the synovium, which can lead to significant morbidity, particularly when associated with osteoarthritis. This case report presents a 48-year-old male with a 2-year history of knee swelling and pain, exacerbated over the last 6 months, resulting in impaired daily activities. Clinical examination and imaging revealed severe osteoarthritis and soft tissue swelling around the knee. Surgical intervention involved total synovectomy and total knee arthroplasty, performed concurrently. The patient exhibited favorable postoperative outcomes, achieving full range of motion and resolution of symptoms. This case underscores the importance of recognizing PVNS as a contributor to knee osteoarthritis and highlights effective surgical management strategies to improve patient quality of life. Follow-up care is crucial to monitor for potential recurrence of the disease.
