A Trial Comparing Mini-posterior Approach and Direct Anterior Approach

Completed · Not applicable

Conditions studied: Osteoarthritis

In brief

The purpose is to determine if differences exist in the attainment of functional milestones that reflect activities of daily living between mini-posterior and direct anterior approach total hip arthroplasty (THA). The investigators also hope to determine if the general health outcome after direct anterior total hip arthroplasty was better than that after mini-posterior-incision total hip arthroplasty as measured with Short Form-12 (SF-12) scores, and to evaluate variation of surgical factors of the two procedures on the basis of the operative time, component positioning, and occurrence of early complications.
