CPT® Code 27334

The procedure described by CPT® Code 27334 refers to an arthrotomy with synovectomy of the knee, specifically targeting either the anterior or posterior compartment. The synovium is a specialized connective tissue that lines the knee joint and is responsible for the production of synovial fluid, which lubricates the joint. In certain medical conditions, such as rheumatoid arthritis or synovial proliferative disorders, the synovium can become inflamed, leading to an overproduction of synovial fluid and resulting in joint effusion. This condition can cause pain, swelling, and reduced mobility in the knee joint. During the procedure, a surgical incision is made over the knee to access the joint. The surgeon carefully dissects the surrounding tissues to expose the joint capsule, which is then opened to allow for direct examination of the knee joint. The joint is flushed with saline to clear any debris, and a motorized shaver is utilized to excise the inflamed synovial tissue. It is crucial to remove all affected synovium while preserving the integrity of the underlying vascular and nervous structures. After the synovectomy is completed, any bleeding is controlled using electrocautery, and the joint capsule is closed, followed by layered closure of the soft tissue and skin. A compressive dressing is applied to support the healing process. This procedure is indicated for patients requiring targeted removal of inflamed synovial tissue to alleviate symptoms and improve joint function.
