Signs & symptoms

PVNS symptoms usually include:
- Swelling and pain at the joint
- Heat at and near the joint
- Limited range of movement of the joint
- Popping sounds of the joint


Most cases of PVNS are diagnosed using magnetic resonance imaging (MRI). Your healthcare provider may ask you about your medical history and symptoms. He or she will conduct a physical examination. Based on the findings you may referred to several diagnostic imaging tests such as Ultrasound, X-ray, computed tomography (CT) scan, or MRI.


People who suffer from PVNS usually need surgery to relieve their symptoms and prevent further damage.
Types of common surgeries that may be part of your treatment are:
- Arthroscopic surgery - the most common surgery and the less invasive one. Using small incisions and a camera, your surgeon will remove all the affected parts of the synovium.
- Open surgery - in more severe cases, a large cut is made so your surgeon can reach the entire joint.
- Total joint replacement - in late-stage PVNS, in case you will need a prosthetic joint to replace current joint.
