Do I need a synovectomy for knee synovitis?

When surgery is considered

• Tenosynovial giant cell tumour, also called PVNS: a benign overgrowth of the lining where removal is the main treatment
• Inflammatory arthritis with one persistently swollen knee despite optimal medicines from a rheumatologist
• Recurrent bleeding into the joint in selected patients
• Synovitis driven by a mechanical problem, such as a meniscus tear, loose body or cartilage flap, treated at the same time
• Septic arthritis, where inflamed tissue is removed during the washout

For synovitis from osteoarthritis alone, synovectomy is not usually helpful; the arthritis itself is the target.

What the operation involves

Arthroscopic synovectomy is done through several small incisions under anaesthetic, usually as day surgery or with one night in hospital. A camera and fine instruments remove the inflamed lining from the different compartments of the knee. Samples are sent to the laboratory to confirm the diagnosis. Extensive disease at the back of the knee occasionally needs an open approach as well.

Recovery

Swelling and some bleeding into the joint are common in the first weeks. Most people walk the same day or next, with crutches for a short period. Physiotherapy focuses on regaining full bending and straightening early, because stiffness is the main risk. Return to desk work is often within one to two weeks, and to sport over several weeks to a few months, depending on the cause. The lining can grow back, so follow-up matters, particularly with tenosynovial giant cell tumour.
