Arthroscopic Management of Pigmented Villonodular Synovitis of the Hip: A Case Report

Background: Pigmented villonodular synovitis, particularly of the hip joint, has been historically treated via open synovectomy. However, an arthroscopic approach to management has been trailed successfully in recent years and has demonstrated encouraging outcomes. Case Presentation: We report the case of a 17-year-old man with pigmented villonodular synovitis of the right hip who underwent arthroscopic treatment. He remains well 5 years later with no signs of recurrence. We discuss the advantages and disadvantages of arthroscopically managed pigmented villonodular synovitis as well as the recent literature surrounding this topic. We also explain a technical tip during hip arthroscopy to access these difficult lesions. Conclusion: Arthroscopy can be used for hip pigmented villonodular synovitis treatment. These lesions may also be accessed by extending the hip to 10 degrees and releasing the traction. There is evidence to suggest that arthroscopically managed pigmented villonodular synovitis carries better outcomes and lower morbidity rates compared to an open approach in suitable cases.
