Minimum 20-year follow-up of a press-fit acetabular cup in cementless total hip replacement in young patients.

Purpose: We aimed to determine the minimum 20-year survival rates of a cementless press-fit cup in young patients.

Patients And Methods: This is a retrospective, single-center, multi-surgeon cohort study investigating the minimum 20-year clinical and radiological outcome of the first 121 consecutive total hip replacements (THRs) using a cementless, press-fit cup (Allofit, Zimmer, Warsaw, IN, USA) performed between 1999 and 2001. 28-mm metal-on-metal (MoM) and ceramic-on-conventionally not highly crosslinked polyethylene (CoP) bearings were used in 71% and 28%, respectively.
