Hip Impingement: Symptoms, Causes and Treatment

Hip impingement occurs when the bones at the front of the hip come too close together during movement, irritating nearby tissues.

Hip impingement, also called femoroacetabular impingement, is a movement-related problem in the ball-and-socket joint. Extra bone shape on the ball, socket or both can reduce clearance when the hip bends and turns. Repeated contact may irritate the labrum and joint cartilage. The finding on an image does not by itself prove that symptoms come from impingement.

Hip impingement commonly presents with pain deep in the groin, especially during sitting, squatting, pivoting or bringing the knee toward the chest. [Groin Pain](/symptoms/groin-pain/) may be accompanied by reduced hip rotation. Some people notice [Hip Clicking and Snapping](/symptoms/hip-clicking/) or aching around the front or side of the hip. [Hip Pain](/symptoms/hip-pain/) can flare after sport or prolonged activity.

Hip impingement is linked to the shape and alignment of the hip bones. That shape may develop while the skeleton grows or follow repeated loading during activities that involve deep flexion and rotation. Irritation can build gradually rather than appearing after one event. A clinician also checks for other explanations, including [Hip Osteoarthritis](/conditions/hip-osteoarthritis/), because several hip conditions can produce similar pain.

Symptoms often vary with the depth, speed and frequency of hip movement. Rest may settle a flare, but repeated provoking positions can bring it back. Some people remain active by changing technique and load; others develop persistent pain or stiffness. Earlier assessment can clarify whether the main issue is the bone shape, irritated soft tissue, joint wear or a combination.

Risk of symptoms rises with activities that repeatedly place the hip in deep flexion, rotation or impact. Training errors, reduced hip and trunk control, limited mobility elsewhere and a rapid increase in activity can add stress. Previous hip injury and family hip shape may also matter. Having one of these factors does not confirm impingement.

Diagnosis combines your symptom pattern with an examination of gait, strength, flexibility and hip movement. The clinician may use a controlled movement test to reproduce familiar pain. X-rays show bone shape and joint space; MRI can assess the labrum, cartilage and other soft tissues when needed. Results are interpreted alongside symptoms, because a shape can exist without causing discomfort.

Initial care often combines activity adjustment, targeted strengthening and movement retraining. [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/) can address hip and trunk control while keeping useful activities in your routine. A [Cortisone Injection](/treatments/non-surgical-orthopedics/cortisone-injection/) may help clarify or settle joint-related pain in selected cases. If symptoms persist despite a suitable non-surgical plan, [Hip Arthroscopy](/treatments/sports-and-arthroscopic-surgery/hip-arthroscopy/) may reshape bone or address damaged tissue.

Notice which hip angles trigger pain and temporarily reduce their depth or repetition. Raise a seat, alter cycling or running demands, and use a gradual return plan rather than testing the hip with a sudden hard session. Keep the exercises prescribed for strength and control, and report pain that becomes constant, interrupts sleep or limits ordinary walking.

Ongoing contact may irritate the labrum or cartilage and can contribute to stiffness and activity limitation. Pain can also change how you walk, placing extra demand on the back or opposite leg. Persistent symptoms deserve reassessment so the diagnosis and treatment plan can be refined.

Build activity gradually, warm up before demanding movement and strengthen the muscles around the hip and trunk. Use technique that avoids forcing the hip into painful depth. Rest between demanding sessions and vary training tasks. These steps may reduce irritation even when the underlying bone shape cannot be changed without treatment.

An orthopaedic clinician, sports-medicine doctor or physiotherapist can assess hip impingement. Choose assessment sooner if groin pain repeatedly limits movement, follows an injury, or comes with locking, marked weakness or inability to walk normally. Take note of the positions, activities and duration that reproduce your symptoms.
