| Summary | PURPOSE:The purpose of this study was to evaluate perioperative and short-term clinical and radiographical results of a modern PS mobile-bearing cementless TKA system.METHODS:A retrospective review of a consecutive series of TKAs was performed by a single surgeon using a cementless or cemented TKA of the same design (Attune, DePuy Synthes, Massachusetts, USA). The 2011 Knee Society Score, Forgotten Joint Score-12, Hip-Knee-Ankle angle, and the presence of radiolucent lines (RLLs) were reviewed 1-year postoperatively with 1:1 matching performed for age, gender, body mass index, and preoperative UCLA score. Fisher's exact test or independent Student's t-test were used for statistical analyses.RESULTS:Forty-five cementless and 45 cemented TKAs were reviewed after 1:1 matching. The mean operative time was 8.8 min shorter (P < .01), and the mean amount of drainage was 40.0 ml greater (P = .04) in the cementless cohort. At 1-year postoperatively, there were no significant differences in both cohorts in 2011 Knee Scores and Forgotten Joint Scores-12, with no patients requiring revision surgery (NS). The incidence of RLLs was significantly higher in cementless TKAs (51%) than that in cemented TKAs (22%, P < .01). However, the mean width of RLLs in the cementless TKAs (0.2 mm) was significantly smaller (P < .01) than that in the cemented TKAs (0.8 mm) at 1-year postoperatively with no progression.CONCLUSION:A recently introduced cementless PS mobile-bearing TKA design demonstrated comparable postoperative and radiographical results to its cemented predecessor at 1-year follow-up.LEVEL OF EVIDENCE:Retrospective cohort study, Level III. |
