Two-year follow-up results of arthroscopic treatment of symptomatic tears of the labrum of the acetabulum in patients with global overcoverage by the acetabulum

The purpose of this study was to report the results at a minimum of two years' follow-up in patients after hip arthroscopy for symptomatic tears of the labrum of the acetabulum, with accompanying global overcoverage by the acetabulum.
This study is a retrospective case series of patients who underwent hip arthroscopy from April 2008 to April 2013. The inclusion criteria were patients with global overcoverage of the femoral head by the acetabulum, defined as a centre-edge angle (Wiberg angle) >40°, and with coxa profunda, defined radiographically by the ilioischial line lying further laterally than the roof of the acetabulum. Only patients with a minimum follow-up of two years and with no previous history of disorders or surgical procedures of the hip were included in the study. The demographic details of the examination, the radiographic assessment and the intraoperative findings were recorded. Clinical assessment was based on patient-reported outcomes.
The authors concluded that hip arthroscopy in patients with global overcoverage of the femoral head by the acetabulum was associated with improvement in the patient-reported assessment scales and in pain over a minimum follow-up period of two years. These improvements did not, however, reach the minimal clinically important differences for the assessment scales. The incidence of secondary surgical procedures was 17%. The type of tear of the labrum was type II, that is, a tear within the substance of the labrum of the acetabulum.
