Abstract

The study prospectively assessed the eleven-year outcomes of cementless total hip arthroplasty using the minimally invasive anterolateral approach (MIS-AL). Enrolled into the study were a total of 104 patients who had had total hip arthroplasty using the MIS-AL approach in our center between 1/2005 and 3/2006. A combination of an Allofit cup and CLS stem was used in all patients (Zimmer Biomet). Patients were assessed using the Harris score, school-like performance rating, evaluation of satisfaction levels (in percent), and evaluation of X-ray scans obtained prior to, 1 year, and 11 years after the procedure. Overall, complete assessment was performed in 75 patients. The Harris score was 91.34 and 91.35 at 1 year and 11 years post-surgery, respectively. One patient required re-implantation for damage to the femoral head at 2 years after the primary implantation and another one replacement for stem loosening because of an inappropriately-sized component. There was no case of infection-related stem loosening. Our results showed that, in indicated cases, the MIS-AL approach can be an alternative to the conventional one; however, while the former has comparable mid-term outcomes, they are not superior to those obtained using standard approaches.
