Effect of high-pressure pulsatile lavage versus manual rinsing on bone cement penetration in total knee arthroplasty: a randomized clinical trial.

研究概要

100 patients undergoing primary cemented total knee arthroplasty (TKA) were randomized and analyzed. Patients were randomized to a manual lavage or high-pressure pulsatile lavage prior to tibial cementation. The primary outcome was cumulative bone cement penetration across ten Knee Society Scoring System (KSSS) zones. Secondary analyses included zone-specific penetration and sensitivity analyses excluding metaphyseal regions. Overall, there were no statistically significant differences in cumulative cement penetration between manual and high-pressure lavage.
