Chronic hip joint pain (CHJP) is a major cause of hip dysfunction in young adults. The term CHJP encompasses a wide range of diagnostic entities, including femoroacetabular impingement (FAI), structural instability, acetabular labral tears and chondral lesions. Hip muscle performance is essential to provide both static and dynamic stability to avoid excessive joint play. However, little is known regarding the association between hip muscle strength and CHJP. The current study compared differences in strength of the hip rotator and abductor muscles between young adults with CHJP and asymptomatic controls.
