A 16-year-old male high-school swimmer with mixed FAI which was treated with elective arthroscopic rim trimming and femoroplasty. During suture anchor placement via mid-anterior portal for anterosuperior labral refixation, the acetabular articular cartilage was elevated but not penetrated by a 3.5-mm knotless anchor (Push-lock, Arthrex, Naples, FL, USA). The anchor was not removed. The patient had an uneventful post-operative course and eventually resumed asymptomatic competitive swimming and intramural collegiate basketball. His pre-operative non-arthritic hip score (NAHS) was 34 and his latest post-operative NAHS was 89 at 6 years following surgery and radiographs show no joint deterioration or narrowing.
