Summary

Pigmented villonodular synovitis (PVNS) most commonly affects the knee, causing pain and disability. Advanced imaging like MRI and arthroscopy aid in early diagnosis and management of PVNS.

Area of Science:

  • Orthopedics
  • Radiology
  • Pathology

Background:

  • Pigmented villonodular synovitis (PVNS) is a rare, benign neoplastic proliferation of the synovium.
  • PVNS can cause significant joint pain and disability, particularly when affecting the knee.

Purpose of the Study:

  • To evaluate the clinical, radiological, and histological characteristics of PVNS.
  • To assess the outcomes of PVNS treatment in a cohort of patients.

Main Methods:

  • Retrospective analysis of 14 pathologically-confirmed PVNS cases from 1990-1999.
  • Review of clinical data, radiographic findings (X-ray, arthrography), MRI, and arthroscopic evaluations.
  • Surgical excision and osmic acid synoviorthesis were employed as treatment modalities.

Main Results:

  • All 14 patients (9 female, 5 male) presented with knee PVNS, with a mean age of 32.7 years at diagnosis.
  • Mechanical pain and disability were the predominant symptoms.
  • Radiographs were normal in 8 patients; arthrography revealed cysts, MRI showed characteristic PVNS findings, and arthroscopy was performed in 4 cases.
  • Recurrence was observed in 4 patients, with an average onset of 10 months post-surgery.

Conclusions:

  • Magnetic Resonance Imaging (MRI) and arthroscopy significantly enhance the early diagnosis and management of pigmented villonodular synovitis.
  • Complete surgical excision is the primary treatment, but recurrence necessitates further evaluation and management strategies.
