Area of Science:

  • Orthopedic Surgery
  • Oncology
  • Pathology

Background:

  • Pigmented villonodular synovitis (PVNS) is a rare, locally aggressive tumor-like condition of unknown etiology.
  • PVNS frequently recurs, posing significant challenges in management and treatment.
  • The pathogenesis of PVNS remains elusive, complicating therapeutic decisions.

Observation:

  • A case of recurrent PVNS after two arthroscopic synovectomies is presented.
  • Clinical, histological, and radiological features of PVNS are discussed in the context of this recurrence.
  • The patient underwent an open synovectomy with bone grafting for cystic lesions in the femur and tibia.

Findings:

  • Post-operative follow-up at three months showed complete pain resolution.
  • Bone density in the previously cystic areas was appropriate, indicating successful bone integration.

  • This approach suggests a viable option for managing complex PVNS cases.

    • Implications:

    • Early and accurate diagnosis of PVNS is crucial due to its often delayed presentation.
    • Treatment strategies for PVNS must be tailored to the specific growth pattern and extent of the disease.
    • Combining different therapeutic modalities, including surgery and radiosynoviorthesis, may be necessary to achieve recurrence-free outcomes.
