A hip labral tear is a tear or fraying of the labrum, the ring of tough cartilage that lines the rim of the hip socket, deepens it and helps hold the joint securely. It causes pain deep in the groin or front of the hip, sometimes with catching, clicking or locking as the torn flap is pinched during movement. Most tears are not from a single injury but from repetitive pinching over time, and the commonest underlying cause is a mismatch in hip shape called femoroacetabular impingement (FAI). Most people are managed successfully without surgery.

In a medical emergency, or for severe or sudden symptoms such as breathing difficulty, chest pain, fainting or stroke signs, call 995 immediately.
True locking of the hip, repeated giving-way, an inability to bear weight, or hip pain after a significant fall or accident needs prompt assessment — and a major accident or an obviously deformed leg is a 995 call.
What it is and why it happens
The labrum acts as a seal and shock absorber for the ball-and-socket hip. In FAI, extra bone on the ball (a cam shape), the socket rim (a pincer shape), or both, means the ball and socket do not fit together smoothly, so bone abuts bone during movement and grinds on the labrum. Over time this repeated pinching frays or tears the cartilage. A single trauma or dislocation can also cause an acute tear, and some labral fraying occurs with age without causing symptoms — so imaging findings do not always equal the source of pain.
Common causes
An abnormal hip shape (FAI) is the leading contributor, along with twisting, pivoting and cutting sports such as football, hockey, dance and martial arts, and sports with repeated deep hip flexion or squatting such as ballet, gymnastics and weightlifting. Repetitive hip motion with high training loads, trauma such as a fall, and structural issues such as a shallow socket (dysplasia) or early osteoarthritis also play a part.
Symptoms
There is usually deep pain in the groin or front of the hip, which can also be felt in the buttock or outer thigh, often a dull ache with occasional sharp catches. Clicking, catching, locking or a giving-way sensation is common, along with stiffness and reduced range of motion. Symptoms tend to be worse with prolonged sitting, walking, pivoting, deep squatting or getting in and out of a car, and may ache at night. They often build gradually, so many people have symptoms for months before diagnosis.
Red flags
Seek prompt care for true locking of the hip, repeated giving-way or buckling, or an inability to bear weight, and for hip pain after a significant fall, accident or dislocation — a major accident or a deformed-looking leg is a 995 situation. Rapidly worsening pain, a fever with a hot, swollen joint (possible infection), or night pain with unexplained weight loss should be seen promptly to exclude other causes.
How it is assessed and treated
Assessment starts with a history and examination, including provocation tests that reproduce the pinch, such as bringing the hip into flexion, adduction and internal rotation. X-rays of the hip and pelvis look at bone shape and rule out arthritis or dysplasia, and MRI — especially an MR arthrogram with contrast injected into the joint — shows the labrum in more detail. A diagnostic injection of local anaesthetic into the joint can confirm the hip is the true pain source. A sports medicine physician or a hip orthopaedic surgeon leads care, with physiotherapists central to management. First-line treatment is non-surgical for most people: physiotherapy to strengthen the hip, core and gluteal muscles and improve movement control, activity modification to reduce the aggravating deep-flexion and pivoting movements, simple pain relief, and sometimes an intra-articular injection that is both diagnostic and therapeutic. Surgery — usually keyhole hip arthroscopy to repair or reshape the labrum and, where FAI is present, reshape the bone — is reserved for people whose mechanical symptoms and pain persist despite good conservative care, and outcomes are generally better when there is little established arthritis.
Realistic expectations and return to sport
Because the labrum has a limited blood supply, a tear usually does not knit back together on its own — but many people become pain-free without surgery, because the goal is to calm symptoms and improve how the hip moves rather than necessarily close the tear. Staying active in a modified form, reducing the specific movements that trigger the pinch while continuing guided strengthening, allows most people to keep training. When surgery is needed, recovery is gradual, often several months of progressive physiotherapy before a full return to sport, on a timeline the surgeon and physiotherapist set individually. Rushing the milestones tends to set recovery back, so a staged, guided return is important.
When to see a doctor
See a doctor for groin or hip pain, clicking or catching that lasts more than a few weeks or interferes with sport, work or daily life, and sooner for any red flag such as locking, giving way, an inability to bear weight, or pain after an injury. Because untreated impingement and labral problems can contribute to cartilage wear over time, an early assessment is worthwhile even when the pain is manageable, so a plan can be put in place.
