United Orthopedic U2 Knee AiO II III Device Description The U2 Knee System’s All-in-One (AiO) femoral block enables surgeons to perform key femoral preparation steps with a single instrument for a faster, more efficient and precise surgical technique. ● Supports both anterior and posterior referencing ● Placed on the resected distal femur ● Permits internal / external rotation adjustments from 3° to 7° in 1° increments ● Allows sizing of all 13 sizes of U2 femoral components ● Ultra-fine anterior-posterior (A / P) adjustment can be made from -2 mm to +2 mm for optimal component positioning ● Used for high-precision anterior and posterior femoral resections ● Sets the position for the anterior and posterior chamfer resections INDICATIONS The U2 Total Knee system is indicated in knee arthroplasty for reduction or relief of pain and/or improved knee function in skeletally mature patients with severe knee pain and disability due to rheumatoid arthritis, osteoarthritis, primary and secondary traumatic arthritis, polyarthritis, collagen disorders, avascular necrosis of the femoral condyle or pseudogout, posttraumatic loss of joint configuration, particularly when there is patellofemoral erosion, dysfunction or prior patellectomy, moderate valgus, varus, or flexion deformities. This device may also be indicated in the salvage of previously failed surgical attempts if the knee cannot be satisfactorily balanced and stabilized at the time of surgery. The device includes Cruciate Retained (CR) type, Posterior Stabilized (PS) type and Ultracongruent (UC) type. CR and UC types are designed to collocate with CR femoral component, while PS type is designed to collocate with PS femoral component. ● For cemented type femoral components, patellar components, tibial baseplate components, tibial inserts components and all poly tibial component: This device is a single use implant and intended for cemented use only. ● For cementless type component and porous coated femoral component: This device is a single use implant and intended for cementless use only.
