External fixator immobilization after extensor mechanism reconstruction in total knee arthroplasty Colin D. Canham, MD, Christopher Walsh, MD, Stephen J.

Figure 1 Photograph of external fixator mounted after extensor mechanism reconstruction. Note that pins are placed far from the knee joint to prevent contamination of total knee components.

Figure 2 Active extension 6 months status post extensor mechanism reconstruction. This patient had a 10° extensor lag. Arthroplasty Today 2018 4, 187-191DOI: (10.1016/j.artd.2016.11.007) Copyright © 2016 Houston Methodist Orthopedics & Sports Medicine Terms and Conditions

Figure 3 Lateral radiograph of the knee demonstrating stemmed revision total knee components and marked patella alta consistent with this patient's patellar tendon rupture.

Figure 4 Postoperative radiographs of the same patient demonstrating a cerclage cable used to assist in reducing the patella. Note the most distal half pin in the femur is placed proximally, outside the surgical field. Likewise, the tibial half pins are placed distal to the cement plug of the tibial component to reduce the risk of contamination of the components.
