Uncemented Total Knee Arthroplasty is on the Rise. A Report of Patient Demographics and Short-Term Outcomes From the Michigan Arthroplasty Registry Collaborative Quality Initiative

The use of uncemented TKA increased from 3.3% in 2017 to 17.1% in 2021, while cemented fixation decreased from 96.7% to 81.9%. There were no significant differences in short-term complications between groups. Uncemented patients were younger, men, took fewer medications, had a shorter length of stay, and were less likely to be readmitted. However, they were more likely to have comorbidities than the cemented group.
