Overview
Brief Summary
This is a prospective, randomized study comparing two different bone preparation techniques for insertion of a hydroxylapatite (HA) coated titanium cementless femoral stem. Patients who receive a unilateral total hip replacement are randomized to either conventional broaching or compaction.
Hypothesis: Compaction results in significantly less stem migration [evaluated by radiostereometric analysis (RSA)], less peri-prosthetic bone mineral density (BMD) loss [evaluated by dual energy x-ray absorptiometry (DEXA)], and a higher Harris hip score after two years.
