Purpose: The purpose of this study was to evaluate 4 hips with symptomatic protrusio acetabuli treated arthroscopically for symptomatic pincer-type femoroacetabular impingement in 3 patients aged younger than 40 years. Methods: Four hips in 3 patients, all active women, aged 26 to 37 years, with hip pain and radiographic evidence of protrusio acetabuli and a center-edge angle (CEA) of 50 degrees or more, were studied and followed up for a minimum of 2.5 years. Each of these patients underwent arthroscopic anterior and lateral acetabuloplasty, partial labrectomy, synovectomy, and chondroplasty. Follow-up included evaluation with the modified Harris Hip Score (mHHS), radiographs, and clinical history and examination. Results: Patient 1 had bilateral hip surgeries. The right hip was followed up for 63 months, and the CEA improved from 67 degrees to 60 degrees, with an mHHS score improvement by 60.4 points. The CEA for the left hip improved from 63 degrees to 53 degrees at 61 months' follow-up, and the mHHS improved by 43.9 points. Both hips had a final mHHS of 100 points. Patient 3, followed up for 28 months, had a final mHHS of 100 points, 32 points better than preoperatively, whereas the CEA improved from 51 degrees to 44 degrees. Patient 3, a 26-year-old with preoperative radiographically apparent arthritis, had a final mHHS of 87 points, 35 points better than preoperatively, and the CEA improved from 50 degrees to 42 degrees at 32 months' follow-up. All 3 patients were happy with their outcomes. Conclusions: In this small case series, arthroscopic acetabuloplasty showed reduced symptoms and improved function in 3 patients with protrusio aged younger than 40 years at a minimum of 2.5 years' follow-up.
