Purpose: To detail our early experience using concomitant hip arthroscopy and periacetabular osteotomy (PAO) for the treatment of acetabular dysplasia.
Accuracy of Component Positioning in 1980 Total Hip Arthroplasties: A Comparative Analysis by Surgical Technique and Mode of Guidance.
The purpose of this multi-surgeon study was to assess and compare the accuracy of acetabular component placement, leg length discrepancy (LLD), and global offset difference (GOD) between six different surgical techniques and modes of guidance in total hip arthroplasty (THA). A total of 1980 THAs met inclusion criteria. Robotic- and navigation-guided techniques were more consistent than other techniques in placing the acetabular cup into Lewinnek’s safe zone (P<0.005 and P<0.05, respectively). Robotic-guided surgery was more consistent than other techniques in placing the acetabular component within Callanan's safe zone (P<0.005). No statistically significant differences were found between groups in the frequency of patients with excessive LLD. Clinically significant differences between groups were not found in the frequency of patients with excessive GOD.
Mixed femoroacetabular impingement (FAI) is typically managed with both femoral and acetabular rim osteoplasties, but it has not been reported if the rim osteoplasty is always required. We hypothesized that mixed FAI managed by femoral or combined femoral and acetabular osteoplasties will both attain satisfactory clinical results, provided intraoperative impingement-free functional motion is attained.
Is intraarticular pathology common in patients with hip dysplasia undergoing periacetabular osteotomy?
Periacetabular osteotomy (PAO) enables correction of bony acetabular deficiency in the setting of hip dysplasia. Patients with insufficient acetabular coverage often have intraarticular pathology, but the degree of this pathology has been incompletely characterized. We have used arthroscopy as an adjunct to PAO to further delineate intraarticular pathology in patients with hip dysplasia with mechanical symptoms.
