The role for hip arthroscopy (HS) in combination with periacetabular osteotomy (PAO) for the treatment of symptomatic acetabular dysplasia has not been clearly defined. In this study, we assessed midterm outcomes of concurrent hip arthroscopy and PAO (HS/PAO) for the treatment of symptomatic acetabular dysplasia with associated intra-articular pathology. We performed a retrospective review of concurrent HS/PAO cases in a prospectively collected institutional hip preservation database. From November 2005 to December 2012, 85 hips in 80 patients underwent combined HS/PAO. Two hips had a diagnosis other than acetabular dysplasia and 12 hips were lost to follow up, leaving 71 hips for analysis at mean 6.6-year follow-up (range 4–11 years). Hips were evaluated using the University of California, Los Angeles (UCLA) Activity Score, modified Harris Hip Score (mHHS), and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscore. Hips were stratified into preserved or failed groups, with failure defined as conversion to THA or a symptomatic hip (mHHS <70 or WOMAC pain subscore > 10). Complications were recorded and graded by the Clavien-Dindo classification. Regression analyses were performed to identify the interaction between patient factors, radiographic measures, and surgical details with outcome.Introduction
Methods
Total hip replacement is a highly successful procedure, yet access to arthroplasty is limited in many developing nations. In response, organizations in the United States have conducted service trips to provide international arthroplasty care to underserved populations. Little outcomes data are currently available related to these trips. We aimed to assess patient outcomes following total hip arthroplasty performed on a surgical mission trip. We completed an arthroplasty service trip to Brazil during which we performed 46 total hip arthroplasties (THA) on 38 patients. Patient demographic data, comorbidity profile, complication data, and pre- and postoperative Modified Harris Hip Score (mHHS), PROMIS Short Form Pain (SF-Pain), PROMIS Short Form Physical Function (SF-Function), and HOOS Jr scores were collected. Baseline and final follow-up scores were compared. In addition, we utilized a novel questionnaire that was designed to determine outcomes most relevant to patients receiving joint replacements in developing countries. A multivariate regression analysis was performed to identify associations between patient factors and outcomes.Background
