Stem design did not have a significant effect on migration for the DL group ( = 0.894). Compared with the DA group, the DL group migrated significantly less for both collared ( = 0.031) and collarless ( = 0.002) stems. Migration was not correlated with function or activity at any time point ( 0.05). Most implant migration occurred from the day of surgery to 2 weeks after the operation and stabilized thereafter, suggesting adequate fixation and a low risk for aseptic loosening in both patient groups. Most implant migration occurre
