To Cement or Not? Two-Year Results of a Prospective, Randomized Study Comparing Cemented Vs. Cementless Total Knee Arthroplasty (TKA)

100 patients undergoing total knee arthroplasty were randomized to receive either cemented or cementless fixation. The purpose of this study was to compare pain-related, functional and radiographic outcomes between the groups over 2 year follow-up, to determine if one technique provided advantageous results. No significant differences between groups were noted for most of the measured outcomes throughout the study, as VAS pain scores, Oxford Knee function scores, tibiofemoral angles, patient satisfaction, and blood loss were similar between both treatments. However, clinical Knee Society Score (KSS) values were significantly better in the cemented group, and more radiolucencies were seen in cementless knees when assessed 2 years after surgery. The authors indicated that they planned to follow-up with the same population at 15 years to assess long-term outcomes.
