            [0] => Introduction :
Villonodular synovitis (PVNS) is a benign tumor of the synovium known for its aggressive growth and local recurrence. Diagnosis is aided by MRI, but differentiation from other conditions like synovial sarcoma remains challenging. This study aims to clarify PVNS's unique features and prognosis among synovial lesions
Methods :
A retrospective study was conducted at IBN EL JAZZAR Hospital in Kairouan, analyzing 20 cases of knee villonodular synovitis from January 2000 to December 2009. Data were collected from patients' medical records and operative sheets
Results :
The study, conducted over nine years at IBN EL JAZZAR Hospital in Kairouan, examined 20 cases of knee villonodular synovitis. Incidence was 2.2 cases/year with an average age of 32.5 years. Most patients were men (75%) and presented with pain and swelling (80%). MRI was crucial for diagnosis, revealing various abnormalities including chondromatosis and meniscal dislocation. Treatment involved total synovectomy (15 patients) and excisional biopsy for localized forms. Recurrences occurred in two cases, treated with subtotal synovectomy. Stiffness in three cases required arthrolysis
Discussion :
This study analyzed 20 cases of knee villonodular synovitis over nine years at IBN EL JAZZAR Hospital. The annual incidence was 1.8 cases per million inhabitants. Despite a typically equal sex distribution, males predominated in our series (80%). Patients averaged 32.5 years, lower than reported previously. Symptoms varied, with chronic pain and swelling common. MRI was crucial for diagnosis, but not always definitive. Treatment involved total synovectomy, with recurrences common, particularly in diffuse forms. A case of villonodular synovitis transforming into monophasic synovialosarcoma raised questions about malignant degeneration. Long-term surveillance is crucial due to frequent recurrences.
Conclusion :
Villonodular synovitis presents diagnostic and therapeutic challenges due to its clinical variability and resemblance to synovialosarcoma. Effective patient care necessitates close collaboration among radiologists, pathologists, rheumatologists, and physiotherapists.
