Summary
Pigmented villonodular synovitis (PVS) is challenging to diagnose. Surgical treatment, including synovectomy or arthroplasty, leads to excellent joint function and no recurrence in PVS cases.
Area of Science:
- Orthopedics
- Pathology
Background:
- Pigmented villonodular synovitis (PVS) is a proliferative disorder of the synovium.
- PVS presents diagnostic challenges due to nonspecific symptoms.
Purpose of the Study:
- To evaluate diagnostic procedures, clinical symptoms, and surgical treatment outcomes for PVS.
Main Methods:
- Retrospective evaluation of six surgically treated PVS cases (five knee, one hip).
- Diagnosis confirmed by histological examination.
- Surgical findings included joint effusion and synovial proliferation.
Main Results:
- Five cases underwent complete open total synovectomy; one received arthroplasty.
- Follow-up averaged 3.5 years (6 months to 6 years).
- All patients achieved excellent or good joint function with no recurrence.
Conclusions:
- Delayed PVS diagnosis is common due to nonspecific symptoms.
- Effective treatment involves surgery: synovectomy for diffuse PVS, arthroplasty/joint replacement for severe bone involvement.
