A snapping, clicking or "clunking" hip — often called snapping hip syndrome — is when a tendon or other structure moves over a bony prominence as the joint moves, sometimes with an audible snap or a visible jolt. On its own, a painless snap is usually harmless and very common, especially in active people, dancers, and gym-goers.
It becomes worth assessing when the snap is painful, getting worse, or comes with catching or giving-way — features that can point to a tendon or labral problem rather than a benign mechanical snap.
The three types of snapping hip
Snapping hip isn't a single condition — it's an umbrella term covering three quite different mechanisms. Knowing which type you have matters, because the underlying cause and the treatment direction are different for each.
1. External (lateral) — most common
The iliotibial band or the gluteal tendons flicking over the outer bony point of the hip (greater trochanter). Often visible as the leg moves — sometimes you can see or hear it from across the room.
It usually shows up in the late stance phase of walking, when stepping up, or when standing from a seated position. Often painless on its own, but when it sits alongside outer-hip pain, it's frequently linked with gluteal tendinopathy — the tendon problem that sits under the greater trochanteric pain syndrome (GTPS) umbrella.

The iliopsoas tendon (the deep hip flexor) snapping over a bony ridge at the front of the pelvis as the hip moves from flexion into extension. The snap is felt as a deep click at the front of the groin, often with movement like bringing the knee up to the chest and then lowering it.
Common in ballet, gymnastics, martial arts and strength training. Usually painless, but can become irritating — and in some cases, persistent internal snapping is associated with iliopsoas-related groin pain.
3. Intra-articular (inside the joint) — the one to take seriously
Catching or locking that comes from inside the joint itself — most often a labral tear or a loose body (a fragment of cartilage or bone floating in the joint). This is the type most likely to be painful and the one that most warrants a proper assessment.
Features that suggest intra-articular snapping: deep groin pain, a sense of something getting stuck, the hip giving way, or pain that doesn't fit a clear external or internal pattern. These cases can overlap with FAI (femoroacetabular impingement) and the labral problems that often come with it.

Usually not. A painless snap rarely needs treatment — many active people have one for years without it causing any problem. Concern rises when the snap becomes painful, is getting worse, comes with catching or locking, or causes the hip to give way. These features suggest a tendon, labral, or other intra-articular problem behind the noise, and they're the ones worth a proper clinical assessment.
What causes it
For external and internal snapping, the common drivers are tightness or altered control of the iliopsoas or iliotibial band, a sudden increase in training (more volume, more intensity, more range), and movement patterns that repeatedly drag a tendon across bone. Intra-articular snapping is different — it has a structural cause inside the joint itself.
What helps
For benign, tendon-related snapping: load and mobility work to change how the tendon moves, addressing training spikes, and improving control through the hip. Not forcing it to "click less" by stretching aggressively — that often makes the underlying tendon irritation worse.
For painful or intra-articular snapping: a diagnosis first. The treatment path for a labral tear, FAI, or loose body is different from the path for an external tendon snap, and getting the wrong one delays recovery.
General information, not a personal programme. If the snap is painful or catching, get a proper clinical assessment before starting any specific rehabilitation plan — the right exercises depend entirely on the underlying cause.
Red flag: hot, swollen hip with fever
A hot, swollen, feverish hip needs urgent medical assessment today — not physiotherapy. This can indicate infection in the joint (septic arthritis) and requires prompt treatment.
When to see a specialist
Get assessed if the snapping is painful, worsening, catching or locking, or causing the hip to give way — especially in an active adult. A specialist hip assessment can identify which of the three types is driving the problem and build a targeted plan around it. If you'd like a working diagnosis before deciding on next steps, a specialist online consultation is often a useful starting point.

Is snapping hip syndrome serious?
Usually not — a painless snap is common and benign, especially in active people. Pain, catching, locking, or giving-way are reasons to get it properly checked, as they can point to a tendon or labral problem.
What are the types of snapping hip?
External (IT band or gluteal tendon snapping over the outer hip bone), internal (iliopsoas tendon snapping at the front), and intra-articular (catching inside the joint — most often from a labral tear or loose body).
How do I stop my hip clicking?
If it's painless, often nothing needs to be done. If it's related to a tendon (external or internal), load and control work usually helps more than aggressive stretching. Painful or catching clicking needs a clinical diagnosis first.
When should I worry about a clicking hip?
If the clicking is painful, getting worse, locks or catches, or the hip gives way — especially in an active adult. These features can point to a labral tear or other intra-articular problem that benefits from a proper assessment.
