Hegde V, Bracey DN, Johnson RM, et al. - In this study, the impact of tourniquet use on cement penetration and radiolucent line (RLL) progression was analyzed. Researchers retrospectively examined individuals undergoing primary TKA with a single surgeon, implant, and cement with a minimum 5-year follow-up. In this study, 61 Individuals per group were 1:1 matched by age (+/-5), gender, BMI (+/-5), and follow-up (+/-2 years). They assessed cement penetration and RLL on the tibia at 6 weeks, and RLL at 1, 2, and 5-years postoperatively applying the Knee Society Radiographic Evaluation System. The findings revealed that tourniquet use improves cement penetration and decreases RLL progression. During cementation, dryer surfaces may improve penetration, resulting in superior initial fixation strength and potentially reducing the long-term risk of aseptic loosening.
