If the flexion, extension, or both gaps and associated soft tissue tension appear to be unbalanced, the following techniques may be employed : Tight Flexion - Tight Extension : Resect Additional Bone from the Tibia If the gap is deemed too tight in both flexion and extension, the surgeon may wish to remove additional bone from the tibia, as it is the common surface to both flexion and extension gaps. The surgeon may re-position the Tibial Cutting Jig 21 to perform this resection. The Gap Gauge 24 may then be utilized to re-access the newly established flexion/extension gap. Balanced Flexion - Tight Extension : Resect Additional Bone from the Distal Femur If the gap is deemed too tight in extension only, the surgeon may wish to remove additional bone from the distal femur, as recutting this surface will only affect the extension gap only. The Distal Femoral Cutting Guide 10 may be repositioned on the femur to perform this resection. Then the Gap Gauge 24 may be utilized to re-access the flexion/extension gap. NOTE : Following the distal femoral recuting, the Femoral A/P Chamfer Cutting Guide 15 is required to recreate the femoral chamfer cuts. Tight Flexion - Balanced Extension : Resect Additional Bone from the Posterior Femur If the Gap Gauge 24 is too tight in flexion only, the surgeon may select to down-size the femoral component and thereby affect the associated flexion gap only. To down-size the femoral component, select an Femoral A/P Chamfer Cutting Guide 15 which is one size smaller than the originally used, and reposition the guide into the original distal femoral drill holes.
