) After the plate is seated and all limbs are appropriately positioned, a combination of 2.7 and 2.4 screws can be placed to achieve absolute stability across the major fracture fragments (Figure 5). Using the most inferior and superior holes, screws are placed inferior-to-superior and superior-to-inferior, respectively, to achieve interfragementary compression. The use of a custom plate permits fixation of each fragment in situations where there are large pieces of articular comminution. Number and size of screws is typically dictated by fracture pattern and bone quality. After peripheral fixation, additional anterior-to-posterior screws can be placed through
the anterior/transverse limbs of the plate. These may require the use of locking screws into comminution typically present at the distal pole or unicortical screws into the stronger cortical bone superiorly. Direct visualization of the articular surface as well as anteroposterior and lateral fluoroscopy is utilized to ensure that screws have not violated the joint surface. Because of the high incidence of inferior pole comminution and poor fixation of the inferior fracture fragment, fixation may be augmented with Krackow sutures. In these cases, two # 5 Fiberwire sutures (Arthrex; Naples, FL) are passed beneath the anterior/transverse limbs of the mesh plate and then medially and laterally through the patellar tendon in Krackow fashion (Figure 6).
