CPT® Code 27437

Arthroplasty of the patella, specifically coded as CPT® 27437, refers to a surgical procedure aimed at addressing degenerative diseases affecting the patellofemoral joint. This procedure is performed without the use of a prosthesis, focusing instead on the restoration of the patella's function and structure. The surgery begins with an incision made over the anteromedial aspect of the knee, allowing access to the joint capsule. Once the joint capsule is exposed and incised, the surgeon inspects the patellofemoral joint for any abnormalities, such as osteophytes, which are bony growths that can impede joint movement. These osteophytes are excised to facilitate better joint function. During the procedure, the patellar cartilage is carefully inspected, and any overgrowth is removed to smooth the articular surface of the patella. This smoothing is crucial for ensuring proper patellar tracking, which is the movement of the patella as the knee flexes and extends. After addressing the cartilage and ensuring that the patella tracks correctly, the incisions are closed in layers to promote optimal healing. This procedure is particularly beneficial for patients suffering from pain and dysfunction due to degenerative changes in the patellofemoral joint, providing them with improved mobility and quality of life.
