A clicking hip is usually caused by a tendon or band of tissue sliding over a bony structure in or around the joint. This is called snapping hip syndrome, and it affects 5 to 10% of the general population. In most cases, the clicking is painless and harmless. When it comes with pain, stiffness, or a catching sensation, it can signal something that needs attention.
The Most Common Cause: Tendons Sliding Over Bone
The hip joint is surrounded by thick tendons and bands of connective tissue that have to glide smoothly as you move. When one of these structures catches on a bony prominence, you hear or feel a click, pop, or snap. There are two main types, and where you feel the click tells you which one you have.
External clicking (side of the hip): This is the most common form. A thick band of tissue running along the outside of your thigh, called the iliotibial band, shifts forward over the bony knob on the side of your hip during movement. The front edge of your largest gluteal muscle can do the same thing. You’ll typically notice this click when walking, standing up from a chair, or rotating your leg. It often feels like your hip is “giving way” for a split second.
Internal clicking (front of the hip or groin): This happens when a deep hip flexor tendon catches on the front of the femoral head or a small ridge on the pelvis as you bring your leg from a bent position to straight. Runners, cyclists, and anyone who does repetitive hip flexion often notice this one. It tends to produce a more subtle, deeper sensation than the external type.
Both types are more common in people who use their hips through large ranges of motion. Dancers are especially prone: 44% of hip pain in dancers involves snapping or clicking. Ballet dancers and women in general have higher rates.
When Clicking Points to Something Inside the Joint
Not all hip clicking comes from tendons on the outside of the joint. A third, less common cause is damage to structures inside the joint itself.
The hip socket is lined with a ring of cartilage called the labrum, which acts like a rubber seal to keep the joint stable. When this cartilage tears, it can produce a clicking or catching sensation with movement. Labral tears typically cause pain in the groin or deep in the front of the hip, and the clicking often happens in specific positions rather than with every step.
Loose fragments of cartilage or bone floating inside the joint can also cause clicking, along with a sensation of the hip locking or getting stuck mid-motion. This is different from tendon-related snapping, which feels more like a quick slide than a lock.
Painless vs. Painful Clicking
The single most important distinction is whether your hip click hurts. Painless clicking that you can reproduce voluntarily, like rolling your hip in a circle, is almost always the tendon-sliding type. Many people have had it for years without any problems. It does not mean your joint is wearing out or that you’re causing damage by letting it happen.
Clicking that deserves a closer look has one or more of these features:
- Groin pain that lingers: A nagging ache in the crease of your groin, especially one that doesn’t improve with rest, can indicate a labral tear or hip impingement.
- Locking or catching: If your hip feels like it gets stuck and then releases, something inside the joint may be interfering with normal motion.
- Stiffness that limits your range: Gradually losing the ability to rotate your leg or bring your knee to your chest suggests a structural issue.
- Pain that worsens with activity: Tendon snapping that was once painless but is now sore after exercise may mean the bursa (a fluid-filled cushion near the bone) has become inflamed from repeated friction.
How a Clicking Hip Gets Diagnosed
A physical exam can usually identify whether the snapping is internal or external. Your provider will ask you to move your hip through specific motions while they watch and feel for the snap. Dynamic ultrasound, where the imaging is done while you actively move your hip, is considered the gold standard for confirming both types of external snapping hip. It’s cheaper than an MRI and gives a real-time view of the tendon catching over bone. MRI is more useful when a labral tear or damage inside the joint is suspected.
Stretches and Exercises That Help
For tendon-related clicking, the goal is to reduce tightness in the structures that are snapping and strengthen the muscles that stabilize the hip. Two stretches recommended by the American Academy of Orthopaedic Surgeons target the most common culprits:
Iliotibial band stretch (for external clicking): Stand next to a wall for support. Cross the leg closest to the wall behind your other leg, then lean your hip toward the wall until you feel a stretch along the outside of your hip. Hold for 30 seconds. Do 2 to 3 sets of 4 repetitions on each side.
Piriformis stretch (for deep hip tightness): Lie on your back with both knees bent and feet flat. Cross the ankle of the affected side over the opposite knee, then pull the bottom thigh toward your chest until you feel a stretch in your hip and buttock. Hold for 30 seconds. Same sets and reps as above.
A physical therapist can add hip flexor stretches for internal snapping and design a strengthening program for the gluteal muscles, which help control how your thigh bone tracks in the socket. Reducing the volume of repetitive hip flexion in your training, at least temporarily, also gives inflamed tissue time to calm down.
When Surgery Becomes an Option
Surgery is reserved for cases where months of stretching, strengthening, and activity modification haven’t resolved painful snapping. The most common procedure is a tendon release, where the surgeon lengthens or partially cuts the tight tendon so it no longer catches on bone. This can be done arthroscopically through small incisions, which tends to have better outcomes than open surgery: about 92% of patients treated arthroscopically had successful pain relief, compared to 78% with open surgery, in a systematic review of studies with at least six months of follow-up.
For labral tears, arthroscopic repair or debridement of the torn cartilage is the typical approach. Recovery from either procedure generally involves several weeks of limited weight-bearing followed by a progressive physical therapy program, with most people returning to full activity within a few months.
Why It Tends to Come and Go
Many people notice their hip clicks more during certain periods, then quiets down. This pattern is normal for the tendon-related type. Tightness fluctuates with your activity level, how much you sit during the day, and how warmed up your muscles are. A week of long drives or desk work can tighten your hip flexors enough to bring the click back. A consistent stretching routine often keeps it manageable without any other intervention.
