Outcomes following the single-incision anterior approach to total hip arthroplasty: a multicenter observational study.

The authors conducted a retrospective, multicenter cohort study of 1,152 patients across nine clinical sites across the United States, evaluating complications and function associated with the anterior approach to total hip arthroplasty using an orthopedic table. Eligible patients included those with primary diagnosis of hip arthritis. Outcomes included hospital stay, use of assistive devices, complications, and function. In the cohort of 1,152 patients treated with the anterior approach to total hip arthroplasty, the authors found (i) an acceptable complication profile with a very low dislocation rate, (ii) an early return to function, and (iii) a decline in complications in surgeons with greater than 100 case experiences.
