Abstract
Patellar fracture and anterior knee pain remain as significiant complications following total knee replacement (TKR). In several TKR studies reported in the literature, the average incidence of anterior knee pain was 12%.<sup>12</sup> Recent long-term, large-cohort studies have reported patellar fracture rates of 0.68%, 1.14%, 3.8%, and 5.2% in TKR populations involving 12,424, 1494, 4583, and 8530 knees, respectively.<sup>5,14,20,23</sup> Even at these relatively low incidence rates, the number of patients experiencing these complications is significant, especially considering the growing number of TKRs performed worldwide. A wide variety of patellar fracture types and locations have been reported.<sup>5,9,23</sup> Fracture type classification includes transverse, vertical, avulsion, and comminuted, with fracture location reported as 40% superior or midbody and 30% inferior pole by Goldberg and associates,<sup>9</sup> and as 28% superior, 18% inferior, 23% comminuted, 13% vertical, 11% transverse midbody, and 6% medial or lateral margin by Ortiguera and Berry.<sup>23</sup>
