United Orthopedic U2 MB Knee Extension and Flexion Gaps Confirmation E. Femoral Trial Preparation F. The extension and flexion joint gaps may be evaluated with the Gap Gauge . Select the 9 mm Gap Gauge initially to assess both the extension and flexion joint gaps. If a thicker gap is required, combine additional Gap Gauge Blocks with different thicknesses and test again. The range of thickness is from 9 mm to 18 mm. If the assessed femoral and extension gaps are optimal, insert the femoral and tibial trials to test overall knee mobility and their relative implant position. Instruments Gap Gauge 18 mm = 9 mm Tibial Insert thickness + 9 mm Femoral Component thickness 18 mm Note: The Alignment Rod may be inserted through the Gap Gauge handle to assess the extramedullary alignment in both extension and flexion. Alignment Rod Caution: Femoral Driver is designed to position the implant and trial, not for final impaction. Please impact gently . CR Femoral Trial Femoral Driver Femoral Impactor Instruments Initial Femoral Trial Insertion Assemble the selected size of CR Femoral Trial to the Femoral Driver . Introduce the femoral trial onto the prepared femur until its sitting 2-3 mm above the resected femoral surface. Strike the CR Femoral Trial onto the resected femur with the Femoral Impactor . 25 26
