Summary
Pigmented villonodular synovitis (PVNS) can lead to popliteal artery disruption, even without joint capsule penetration. Careful knee arthroscopy is crucial in patients with PVNS history to prevent arterial injury.
Area of Science:
- Orthopedic Surgery
- Vascular Surgery
- Pathology
Background:
- Pigmented villonodular synovitis (PVNS) is a rare condition affecting joints.
- Previous extensive surgeries, including open synovectomies, increase complication risks.
- Popliteal artery involvement is a serious, though uncommon, complication.
Observation:
- A case report details a patient with a history of PVNS and multiple synovectomies.
- The patient experienced a disruption of the popliteal artery.
- No penetration of the posterior capsule was observed.
Findings:
- Pigmented scar nodules were found densely binding the popliteal artery to surrounding tissues.
- This adhesion likely contributed to the arterial disruption during knee procedures.
- Arterial injury occurred without direct capsular breach.
Implications:
- Arthroscopists must exercise extreme caution during knee joint distension and instrumentation in PVNS patients.
- Awareness of potential vascular complications is critical for patient safety.
- This case highlights the importance of meticulous surgical technique in complex joint cases.
