CPT® Code 27487

The procedure described by CPT® Code 27487 refers to the revision of a total knee arthroplasty, which is a surgical intervention aimed at correcting issues related to a previously implanted knee prosthesis. This revision may be necessary due to various complications, including mechanical failures of the implant or complications such as infections. During this procedure, both the femoral and tibial components of the knee prosthesis may be revised, which involves a comprehensive approach to address the underlying issues effectively. The surgical process begins with a long incision that is strategically made over the femur, extending down over the knee and onto the tibia. This allows the surgeon to access the knee joint while carefully dissecting the surrounding soft tissues, ensuring the protection of vital nerves and blood vessels. The removal of the existing femoral and/or tibial components is followed by an evaluation of any bone loss that may have occurred. If significant bone loss is identified, a bone allograft may be utilized, which is sourced from a bone bank and shaped to fit the defect. The procedure may also involve the use of internal devices, such as metallic cages, plates, and screws, to restore the bone's structural integrity. After reconstructing the bone, a new prosthesis is implanted, and if necessary, adjustments are made to the knee ligaments to ensure proper function. The procedure concludes with the evaluation of patellofemoral tracking and the securement of the new components, ensuring that the knee joint functions optimally post-surgery.
