Metaphyseal Engaging Short and Ultra-Short Anatomic Cementless Stems in Young and Active Patients

We report 400 patients (mean age, 53 years) who received a short stem (17.8 years of follow-up) and 201 patients (mean age 53 years) who received an ultra-short stem (12.3 years of follow-up). At the final follow-up, the mean Harris hip score, WOMAC score and the mean UCLA activity scores were not different between two groups. No patient had thigh pain in either group. Two hips (0.3%) in the short stem group were revised because of early postoperative infection and one hip (0.2%) in the ultra-short stem group was revised for fracture of the proximal femur. Metaphyseal engaging short and ultra-short anatomic cementless stem without diaphyseal fixation provided long-term durable fixation in young and active patients.
