Key Points

  1. Osteochondroplasty and labrum procedures were not associated with osteoarthritis (OA) prevention.

BACKGROUND & OBJECTIVE

Femoroacetabular impingement (FAI) is described as a pathologic contact between the femur and the acetabulum due to incongruity between the shape of the proximal femur and the acetabulum (2,3). Based on clinical experience of more than 600 hip surgical dislocations, Ganz et al. proposed FAI as a mechanism for developing early osteoarthritis (OA) (4). The osteoplasty procedures associated with FAI focus on correcting the anatomic morphology, which is proposed to lead to OA.

This study aimed to assess the effect of osteochondroplasty on OA prevention, comparing radiological evolution between identical hips from the same patient who had undergone unilateral surgery.

Femoroacetabular impingement is described as a pathologic contact between the femur and the acetabulum.
bulb
A minimum of 3 months of non-surgical care is warranted in these patients.

METHODS

  • The study is a retrospective review of 56 consecutive FAI patients who had undergone unilateral arthroscopy in 2009. The operated (OP) and non-operated (N-OP) hips were compared in all patients.
