Clinical and radiological outcomes of an uncemented metaphyseal short stem at minimum 10 years of follow-up: a prospective observational study

Letter to the editor: ‘The history of the development of the regular straight stem in hip arthroplasty’

“…A retrospective cohort study was published comparing the survival rate of 374 GTS stems (0.8%) and 321 CLS (0.4%) at an average follow-up of 5 years, showing no statistically significant difference ( P = 0.63) ( 4 ). A recent prospective case series of 163 patients (172 GTS stems) at a minimum follow-up of 10 years was published ( 7 ). In this study the authors observed a 99.6% survival rate for any cause of failure (96% CI: 1.06–1.97) with only six failed cases undergoing revision surgery for aseptic loosening (four cases), metallosis (one case), and periprosthetic fracture (one case).…”
