Total Knee Arthroplasty. ATTUNE(R) PS (Depuy)
Nowadays joint replacement surgery is one of the most successful procedures in all of medicine. It is a safe and effective procedure designed to decrease pain and allow normal activities by correcting anatomical deformities caused by a number of conditions associated with arthritis (osteoarthritis, rheumatoid arthritis, post-traumatic arthritis...). More than 600,000 knee replacements are performed each year in the United States. The video shows the case of a 75-year old woman diagnosed with severe tricompartmental gonarthrosis in the right knee (type III in the Alhbäck classification), with a 5º varus mechanical femorotibial angle. At the moment of the surgery, the patient had a BMI of 33 Kg/m2 and a personal history of anxiety, bipolar disorder and hypothyroidism (ASA II). Intrarachynous anesthesia plus locoregional block. Antibiotical prophylaxis included 2g of Cefazolin ev. The patient is positioned in supine position with a 300 mm Hg ischemia cuff and usual sterile notching. During the video a step-by-step description of the technique is provided: resurfacing of the ends of the femur and tibia, position of the meta implants, resurfacing of the patella and spacer insertion. An ATTUNE® Knee System posterior stabilized prosthesis is employed. This device allows surgeons to manage a broad range of complex primary and revision knee procedures. The system is designed not only to address bone defects but also provide stability, provide enhanced fixation options, and deliver an efficient technique.
