- Patients with femoroacetabular impingement syndrome (FAIS) have reduced hip joint range of motion (ROM) when compared to healthy controls.
BACKGROUND & OBJECTIVE
Femoroacetabular impingement syndrome (FAIS) is a common cause of hip-related pain in young to middle-aged individuals (1). FAIS can lead to intra-articular damage (e.g. labral tears and cartilage defects) and expediate the development of hip osteoarthritis (2).
When present, FAIS can affect physical function and quality of life (1), as well as result in musculoskeletal impairments including reduced muscle strength and joint range of motion (ROM) (3). Hip joint ROM is of particular interest in clinical practice as it can be used in the diagnosis of FAIS and appears to have a relationship to hip OA development (2,4).
Further, operative, and non-operative treatments often focus on improving hip joint ROM in patients with FAIS. Despite this growing interest in the role of hip ROM in FAIS, several studies have reported conflicting findings (3). Greater clarity on the link between FAIS and hip joint ROM may improve treatment selection and patient outcomes.
This systematic review and meta-analysis sought to investigate the association between FAIS and hip joint ROM.
When deficits in hip joint range of motion exist, clinicians should undertake further clinical and imaging tests to confirm the presence of Femoroacetabular impingement syndrome.
