Often asked: What Is A Poly Swap In Orthopedics?

What does Poly exchange mean?

Poly exchange means replacing the polyethylene tibial insert component of the Plaintiff’s left knee implant.

What is the poly in a knee replacement?

A fixed bearing knee replacement (conventional knee replacement ) means the polyethylene insert (plastic liner between the two metallic surfaces) is fixed inside the tibial tray. A high flex knee is one where the femoral component is designed to achieve greater degree of knee flexion (bending).

What is a spacer in orthopedics?

Definition. Static spacers keep the knee joint in full extension or minimal flexion. Although they prevent movement of the knee, they preserve the joint space and deliver local antibiotic. The static spacer may be considered a temporary antibiotic-loaded knee arthrodesis.

What is the CPT code for polyethylene Exchange knee?

You should bill this procedure using 27486 (revision of total knee arthroplasty, with or without allograft; one component), potentially adding modifier -52 (reduced services), says Robert Haralson, MD, the American Academy of Orthopedic Surgeons (AAOS) coding committee chair.

Is revision knee surgery successful?

In 85% to 90% of people who have a total knee replacement, the knee implants used will last about 15 to 20 years. This means that some patients who have a knee replacement at a younger age may eventually need a second operation to clean the bone surfaces and refixate the implants.

How long does it take to do a knee revision surgery?

Revision total knee replacement is more complex and takes longer to perform than primary total knee replacement. In most cases, the surgery takes from 2-3 hours.

Why is polyethylene used in knee replacement?

Polyethylene (PE) remains the gold standard for the articulating surface in hip and knee arthroplasty. To increase arthroplasty longevity and improve wear resistance, newer versions of PE have been designed with resultantly different wear properties.

What are the components of a total knee replacement?

Total knee replacement surgeryTotal knee replacement consists of three main components: the femoral component, the tibial component, and the plastic spacer (polyethylene). The following model shows the components of a knee replacement.

What is gap balancing in total knee arthroplasty?

When it comes achieving correct femoral component positioning during TKA, one commonly used technique is gap balancing. This method is successfully employed by many surgeons and involves balancing tension and flexion gaps before femoral bone cuts are made.

What is the difference between articulating spacer and static spacer?

Articulating spacers can provide better ROM and knee function scores after revision surgery when compared to static spacer while not compromising the infection eradication rate, soft tissue contracture during exclusion period, and knee pain scores.

How long do antibiotic spacers stay in?

The spacers are left in for about six weeks during which time patients can use a walker or wheelchair to get around. In some cases, depending on the severity of the problem, a second spacer might need to be put in to completely rid the area of infection.

What is the advantage of spacer during construction?

Advantages of static spacers include low-cost, ease of implantation and immobility of the wound, which may be important for soft tissue healing.

What is procedure code 27487?

27487. Revision of total knee arthroplasty, with or without allograft; femoral and entire tibial component. Removal. 27488. Removal of prosthesis, including total knee prosthesis, methylmethacrylate with or without insertion of spacer, knee.
