In a 2011 study, Jan Vanlommel and colleagues reviewed the literature related to cement interdigitation in TKA and declared that 3 to 5 mm of cement penetration was ideal in providing excellent implant stability.3 Building on this study, it has been found that improperly intruded cement can cause many complications. Too high, and the risk of thermal necrosis4 and BCIS5 increase; too low, and the cement-bone interface provides more reduced shear strength, as well as a higher risk of aseptic loosening and revision over time.6 High intrusion also reduces the amount of bone stock remaining in the event of revision.7 Importantly, the high intrusion of Simplex P+T® in the above study was also observed in a study conducted by Stryker employees.8
