• A Randomized Clinical Trial of Direct Anterior Approach and Mini-Posterior Approach Total Hip Arthroplasty Rochester, Minn.

• Actis Total Hip System 2 Year Follow-up (Actis14014) Rochester, Minn.

  The purpose of this study is to collect 2 years of information regarding the performance of the commercially available Actis™ Total Hip replacement system in order to evaluate the clinical outcomes.

• Patients’ Perception of Surgical Incisions Following Two Approaches for Total Hip Arthroplasty Rochester, Minn.

  Patients undergoing a total hip arthroplasty (THA) using either a direct anterior or posterolateral approach will be asked to return to clinic 2 years following THA to evaluate their scars from the incisions. Both the Patient Observer Scar Assessment Scale (POSAS) and the Stony Brook Scar Evaluation Scale (SBSES) will be used to assess patients’ scars. The results of these evaluation scales will then be compared between the anterior and posterolateral approach cohorts.
