Outcomes Between Stemmed and Stemless Total Shoulder Arthroplasty: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

16 Regarding the glenoid implant, there was a radiolucent line at the last follow-up in 14.3% of the stemless TSA and 26.7% in the stemmed TSAs, although the difference did not reach statistical significance. 16 Romeo et al 19 did not observe radiolucent lines on follow-up imaging at any time point; however, they noted that this may be due to the relatively short follow-up period in comparison with studies that described this in stemless designs. 16 , 35 Mariotti et al 17 also reported no radiographic signs of loosening in the course of follow-up.
