Femoroacetabular impingement (FAI) is a cause of hip pain in young adults. It is caused by abnormal morphology in the head of the femur (CAM) or the acetabulm (PINCER). That leads to abnormal contact between the acetabular rim and the head of the femur resulting in repetitive microtrauma to the hip.[1]
The maximal squat test is used for screening for FAI. Maximal or deep hip flexion during a squat, initiates the engagement of the CAM type femoral deformity into the acetabular socket.[1]
Technique[edit | edit source]
The patient stands with their legs shoulder apart and perform a deep squat reaching as low as possible.
The test is positive if the maximal squat recreated the patient’s typical hip and groin pain.[1]
Evidence[edit | edit source]
The sensitivity and specificity of the maximal squat test were 75 % and 41 %, respectively, for CAM-type FAI deformity. The positive and negative likelihood ratios were modest at 1.3 and 0.6, respectively.[1]
