Abstract: Cementless femoral components used in total hip arthroplasty, are designed as proximally coated and fully coated stem. There is still debate regarding differences in clinical outcome scores and thigh pain incidence. We studied these variables in our retrospective study of 50 patients (mean age group was 44.34 years) of which 25 were operated with proximally coated (group A) cementless M/L tapered femoral stem (Zimmer- Biomet) and 25 with fully coated (group B) cementless CORAIL femoral stem (DePuy-Synthes). Patients with minimum follow up of 1 year with post-operative follow up at the interval of 3 months, 6 months and 1 year were selected for the study. We observed no difference with preoperative and postoperative clinical outcome scores (WOMAC, Harris Hip Score) and thigh pain incidence with the two groups. Both proximally coated and fully coated cementless femoral components performed well with no clinical differences at 1 year follow-up.
