Hip Impingement
Hip impingement occurs when the ball and socket of the hip joint rub together during movement, causing groin pain, stiffness, and reduced mobility.
What is hip impingement?
Hip impingement, also called femoroacetabular impingement, is a condition where the bones of the hip joint rub or catch against each other. This can cause pain, stiffness, and reduced movement, especially during sport, exercise, or long periods of sitting.
It happens when the ball and socket of the hip joint do not move smoothly together. The hip is a ball-and-socket joint. The ball is at the top of the thigh bone, and the socket is part of the pelvis.
When the shape of the ball or socket is slightly different, the bones can rub together during movement. This can pinch the soft tissues around the joint and damage the labrum, which is the ring of cartilage around the hip socket. Over time, this may also affect the smooth cartilage that protects the joint.
There are 3 main types of hip impingement:
cam impingement – extra bone on the ball of the hip joint means it is not fully round
pincer impingement – extra bone around the hip socket covers too much of the ball
mixed impingement – both cam and pincer changes are present
Some people have hip impingement but no symptoms. Others may develop pain when the hip is under more strain, such as during sport or repeated deep bending. The condition can affect active people, younger adults, and athletes, but it can also affect people who do not play sports.
At Welbeck, our orthopaedic consultants diagnose and treat hip impingement using advanced imaging, tailored physiotherapy plans, injection treatments, and surgery where needed.

More information
Hip impingement often causes pain at the front of the hip or in the groin. Symptoms can build up slowly and may come and go at first.
Common symptoms include:
groin pain
pain at the front of the thigh
pain on the outside of the hip or buttock
stiffness in the hip
reduced hip movement
catching, clicking, or locking in the hip
limping
pain when sitting for a long time
pain when getting up from a chair
pain when squatting, twisting, pivoting, or lunging
pain during or after running, sports, gym training, and other activities
Some people describe the pain as a deep ache. Others feel a sharp, stabbing pain with certain movements, such as bringing the knee towards the chest or turning the hip inwards.
Hip impingement is usually linked to the shape of the hip bones. These shape changes may develop during childhood or teenage years as the bones grow. Symptoms may develop later in life if the hip is placed under repeated strain.
Possible causes and risk factors include:
natural differences in the shape of the hip joint
repeated twisting, squatting, or pivoting movements
high-impact sports
sports during adolescence, such as football, rugby, hockey, dance, or athletics
previous hip conditions during growth
reduced strength or control around the hip and pelvis
family history of hip shape changes
carrying excess weight, which can place more load on the joint
Sport does not always cause hip impingement. However, active people may notice symptoms sooner because they use their hips more often and with more force.
At your first consultation, your Welbeck consultant will ask about your symptoms, medical history, activity levels, and any previous hip injuries. They’ll want to know where you feel pain, when it started, what makes it worse, and what helps.
They may then examine your hip. This can include checking your walking pattern, hip strength, flexibility, and range of movement. A common examination involves bending and gently rotating the hip to see whether this brings on your usual pain.
Your consultant may recommend tests to confirm the diagnosis and check for related joint damage. These may include:
X-ray – to look at the shape of the hip bones and check for signs of arthritis
MRI scan – to look at the labrum, cartilage, and other soft tissues
CT scan – to show the shape of the bone in more detail
These tests help your consultant understand the type of impingement you have and whether there’s a labral tear or cartilage damage. This helps them recommend the most appropriate treatment.
You can’t always prevent hip impingement, especially if it’s linked to the natural shape of your hip bones. However, you may be able to reduce symptoms and lower the risk of flare-ups by changing how much stress goes through the joint.
Things that may help include:
building strength in your hip, buttock, thigh, and core muscles
improving hip control and balance
warming up before exercise
avoiding repeated deep squats or lunges if they trigger pain
changing training loads gradually
reducing activities that cause sharp hip pain
using good technique during sports and gym exercises
keeping a healthy weight to reduce pressure on the hip
seeing a specialist if hip pain lasts more than a few weeks
It’s important not to stop all activity unless your consultant advises this. Staying active in the right way can help protect your strength, mobility, and overall health.
Hip impingement can place extra pressure on the labrum and cartilage in the hip joint. If symptoms continue and the joint keeps catching or rubbing, this may lead to further damage.
Possible complications include:
ongoing hip pain
reduced movement
reduced ability to exercise or play sports
labral tears
cartilage damage
early osteoarthritis in some people
Not everyone with hip impingement develops complications. Early diagnosis and the right treatment plan can help manage symptoms, protect the joint, and reduce the impact on daily life.
Treatment depends on your symptoms, the type of impingement, your activity levels, and whether there’s damage to the labrum or cartilage. Your consultant will explain your options and help you decide what is right for you.
Treatment options may include:
activity changes – reducing or adapting movements that trigger pain, while keeping you safely active
physiotherapy – exercises to improve hip strength, control, flexibility, and movement patterns
pain relief – medicines such as anti-inflammatory tablets may help some people, if safe for them
image-guided injection – a steroid injection may reduce inflammation and pain inside the joint
hip arthroscopy – keyhole surgery to reshape the bone, repair or trim the labrum, and treat cartilage damage, where possible
open surgery – rarely needed, but may be considered for more complex hip shape problems
Many people start with non-surgical treatment options. Surgery may be recommended if symptoms are severe, if pain affects your quality of life, or if scans show damage that’s unlikely to improve with physiotherapy and activity changes alone.

Frequently asked questions
No, but the conditions are closely linked. Hip impingement describes the way the bones rub or catch in the hip joint. A labral tear is damage to the ring of cartilage around the hip socket. Hip impingement can increase the risk of a labral tear because of repeated pinching in the joint.
Yes, some people manage their symptoms well without surgery. Physiotherapy, activity changes, and pain relief can help reduce discomfort and improve movement. Surgery may be considered if symptoms continue despite treatment or if there’s a labral tear or cartilage damage that needs repair.
This varies from person to person, but deep squats, heavy lunges, twisting movements, and high-impact exercise can make symptoms worse for some people. You don’t need to avoid all exercise altogether. A physiotherapist can help you adapt your routine, so you stay active without repeatedly irritating the hip.
You should see a consultant if hip or groin pain lasts more than a few weeks, keeps coming back, affects sports or daily movement, or causes catching, locking, or limping. You should also seek urgent medical advice if you have severe pain after an injury, cannot put weight through your leg, or feel unwell with a painful, swollen joint.
