Evidence suggests that a thicker cement mantle improves fixation strength and resistance to tensile and shear forces in the tibial component of total knee arthroplasty. A low proportion of orthopaedic surgeons currently use techniques to improve cement penetration in the tibial plateau. We demonstrate that the use of a pressurized cement gun or cement syringe provides a highly statistically significant difference (P < .001) to the depth of the tibial cement mantle and reduction in radiolucent lines when compared to cement applied by hand. This ensures a thicker cement mantle and may reduce the possibility of early failure by improving the strength of fixation and the resistance to tensile and shear forces. There is no statistical difference in the cement mantle produced by the cement syringe and the cement gun.
有证据表明，在全膝关节置换术的胫骨部件中，较厚的骨水泥套可提高固定强度以及抗拉伸和剪切力的能力。目前只有低比例的骨科医生使用技术来提高骨水泥在胫骨平台的渗透。我们证明，与手工涂抹骨水泥相比，使用加压骨水泥枪或骨水泥注射器在胫骨骨水泥套深度方面具有高度统计学显著差异（P <.001），并且可减少射线可透线。这确保了更厚的骨水泥套，并可能通过提高固定强度和抗拉伸及剪切力的能力来降低早期失败的可能性。骨水泥注射器和骨水泥枪产生的骨水泥套没有统计学差异。
