Are There Tendons in Your Hip? Anatomy and Conditions

The hip is one of the most tendon-rich regions in the body. More than a dozen tendons cross or attach near the hip joint, connecting the powerful muscles of the pelvis, thigh, and trunk to bone. These tendons do far more than passively anchor muscle to skeleton: they transmit the forces that let you walk, run, climb stairs, and stabilize your pelvis with every step. When any of them becomes irritated, torn, or degenerated, the resulting pain can be surprisingly hard to pin down, sometimes mimicking back problems or bursitis.

Which Tendons Are in the Hip, and What Do They Do

Thinking of the hip as a single joint with a couple of tendons drastically undersells the area’s complexity. The hip is surrounded by layers of muscles, and nearly every one of those muscles transitions into a tendon before anchoring to the pelvis or femur. A useful way to organize them is by which direction they pull.

On the outer side of the hip, the gluteus medius and gluteus minimus tendons attach to the greater trochanter, the bony bump you can feel on the outside of your upper thigh. The gluteus medius has two structurally distinct tendon portions: a thick posterior part that converges on the back of the trochanter, and a thinner anterolateral part that attaches to the side of the trochanter.

Together, the gluteus medius and minimus form what is sometimes called the “hip abductor mechanism.” Their job is to keep your pelvis level when you stand on one leg, which happens with every single step you take. Researchers have drawn direct parallels between these tendons and the rotator cuff of the shoulder, because both are small tendon groups that stabilize a ball-and-socket joint and are vulnerable to similar types of wear-and-tear tears.¹ That comparison is not just a metaphor: because the pathology and surgical repair strategies overlap, advances in shoulder rotator cuff surgery have influenced hip abductor repair as well.²

At the front of the hip, the iliopsoas tendon is the main hip flexor. It runs deep inside the pelvis, crosses the front of the hip joint, and inserts on the inner side of the upper femur. Because of its path over bony prominences, it is a common culprit in snapping hip syndrome. The rectus femoris, part of the quadriceps group, also has a tendon origin at the hip: it attaches to the pelvis via two distinct heads, a direct head and an indirect head, that merge into a conjoined tendon before the muscle belly begins.

On the inner thigh, the adductor tendons connect several muscles to the pubic bone. The adductor longus tendon has a particularly interesting anatomy: at its origin on the pubic crest, the structure is roughly 60 percent muscle and 40 percent tendon, and that tendon portion narrows rapidly over just a couple of centimeters.³ Superficial fibers of the adductor longus tendon actually cross the midline and fuse with the abdominal muscles and the pubic joint capsule, creating a web of connective tissue that explains why groin injuries in athletes can feel so diffuse.⁴

At the back, the hamstring tendons originate from the ischial tuberosity, the “sit bone” you feel when sitting on a hard surface. The proximal hamstring tendon is a common site of chronic tendinopathy in runners and is also the structure that ruptures in acute hamstring avulsions.

How Hip Tendons Keep You Upright

You might assume that body weight and gravity are the main forces acting through the hip during walking, but modeling studies tell a different story. Muscles and their tendons generate the overwhelming majority of the contact force inside the hip joint. Gravitational and centrifugal forces combined account for less than five percent of total hip contact force during normal walking.⁵ Four muscle-tendon units dominate: the gluteus medius, gluteus maximus, iliopsoas, and hamstrings. When any of these tendons is compromised by injury or degeneration, the mechanical balance of the hip shifts, and compensatory patterns develop that can cause pain in seemingly unrelated areas like the knee or lower back.

From an evolutionary perspective, human hip tendons are arranged quite differently from those of other great apes. The shift to habitual two-legged walking involved compacting the pelvis, extending the spine and hip into a vertical column, and lengthening the femur. These skeletal changes came with extensive soft-tissue remodeling: relative muscle volumes changed, tendon attachment points migrated, and some muscles changed their primary function altogether. The result was a hip optimized for energy-efficient walking and long-distance running, though at a cost to raw power for activities like climbing or sprinting.⁶

Snapping Hip Syndrome

If you have ever heard or felt an audible pop or snap in your hip when swinging your leg, you have experienced what clinicians call “coxa saltans,” or snapping hip. It comes in two main flavors, both caused by tendons. External snapping happens when the iliotibial band (a long, thick band of connective tissue running down the outside of the thigh) slides over the greater trochanter. Internal snapping involves the iliopsoas tendon catching on a bony ridge at the front of the pelvis.⁷

Dynamic ultrasound studies have revealed that the snap is not always the tendon sliding over bone in the way most people picture it. In a study using real-time ultrasound on hips with reproducible snapping, the most common mechanism was the iliopsoas tendon suddenly flipping around the iliac muscle and making abrupt contact with the pubic bone, producing an audible sound.⁸ Less commonly, people have a bifid (split) iliopsoas tendon, where two tendon heads flip over each other during hip flexion, producing the snap.⁹ Most cases of snapping hip are painless and need no treatment. When the snapping is painful and does not respond to stretching and activity modification, surgical release of the offending tendon is an option.

Greater Trochanteric Pain and the Bursitis Myth

For decades, pain on the outside of the hip was reflexively diagnosed as “trochanteric bursitis,” the assumption being that a small fluid-filled sac (bursa) near the greater trochanter was inflamed. Imaging evidence has quietly demolished that narrative. In a large ultrasound study of 877 patients presenting with greater trochanteric pain, roughly 80 percent had no bursitis at all. The most common finding was gluteal tendinosis, present in about half of patients, followed by a thickened iliotibial band in about 29 percent. Actual bursitis showed up in only about one in five cases.¹⁰

This matters because treatment for bursitis (typically a steroid injection into the bursa) and treatment for tendinopathy (progressive loading exercise, sometimes surgery) are very different. If your hip pain on the outer side was labeled “bursitis” without imaging, there is a good chance the real problem is the tendon, not the bursa.

Gluteal Tendinopathy and Tears

Gluteal tendinopathy is the most common tendon condition in the hip, especially in women over 40. The gluteus medius and minimus tendons develop microscopic structural changes: collagen disorganization, increased water content, and sometimes calcium deposits. Pain is usually felt on the outer hip and can be sharp when lying on the affected side at night or when climbing stairs.

A related but distinct condition is an actual gluteal tendon tear, which can be partial or full-thickness. These tears range from subtle fraying visible only on imaging to complete detachment from the trochanter. When the tendon detaches fully, the pelvis drops on the opposite side during walking, producing a characteristic limp called the Trendelenburg gait.

Degenerative tendon changes in the hip may also be linked to osteoarthritis. In a study comparing tendon samples from patients with hip osteoarthritis to those with other hip conditions, every tendon sample in the osteoarthritis group showed scar tissue, compared to half in the non-arthritis group. The osteoarthritis tendons also had more calcium deposits and structural changes at the fiber level, suggesting that periarticular tendon degeneration and joint cartilage degeneration are closely connected processes.¹¹

Why Hip Tendon Pain Gets Misdiagnosed

One of the more frustrating aspects of hip tendon problems is how often they masquerade as something else. Calcific tendinopathy of the gluteus medius, where calcium deposits build up inside the tendon, can produce pain that radiates down the outer thigh in a pattern that closely mimics a pinched nerve in the lower back. Because the iliotibial tract and lumbar nerve dermatomes overlap anatomically, even experienced clinicians can mistake tendon-origin pain for lumbar radiculopathy.¹² If you have been treated for a “back problem” with no improvement and your pain is centered around the outer hip, the tendon is worth investigating.

Imaging helps, but it is not infallible. A systematic review of MRI and ultrasound for detecting gluteal tendon tears found that MRI sensitivity ranged widely, from 33 to 100 percent, while ultrasound was more consistently sensitive at 79 to 100 percent.¹³ A more recent comparison found that ultrasound correctly identified most pathological tendons but also flagged several normal tendons as abnormal, while MRI missed a fair proportion of confirmed pathology. Both modalities struggled to distinguish between tendinosis (degeneration without a tear) and partial-thickness tears.¹⁴ The practical upshot is that imaging is a useful guide, but the clinical picture and physical examination still carry considerable weight.

Proximal Hamstring Tendinopathy

The hamstring tendons attach to the ischial tuberosity at the base of the pelvis, and chronic irritation there produces a deep, aching pain in the lower buttock that worsens with sitting, sprinting, or hill running. On MRI, symptomatic hamstring tendons are measurably thicker than healthy ones, and the surrounding tissue shows more fluid signal. Interestingly, more than 90 percent of all proximal hamstring tendons, symptomatic or not, show some degree of internal signal change on MRI, which means that MRI “abnormalities” in this area are not always meaningful.¹⁵ A swollen tendon with surrounding edema and bone marrow changes at the ischial tuberosity is a more reliable indicator of a genuine problem than signal changes within the tendon alone.

Treatment for Hip Tendon Problems

The evidence base for treating hip tendon conditions has grown considerably in recent years, and exercise-based rehabilitation has emerged as the most consistently supported first-line approach for gluteal tendinopathy. A meta-analysis found that exercise programs were better than minimal intervention (such as a “wait and see” approach) for improving function in both the short and long term. When compared head-to-head with corticosteroid injections, exercise and injections produced similar pain relief, but exercise had a higher overall treatment success rate.¹⁶ Combining exercise with patient education showed a medium-sized effect on pain and function in the short term, with smaller but sustained effects at longer follow-up.¹⁷

Corticosteroid injections deserve a more nuanced reputation than they usually get. They can provide rapid relief, sometimes within days, but the effect tends to peak around six weeks and fade after that. For people who need to function immediately, a steroid injection buys time, but it is not a long-term fix and does not change the underlying tendon structure.

Platelet-rich plasma (PRP) injections have attracted interest as an alternative. In a randomized controlled trial comparing a single PRP injection to a single corticosteroid injection for gluteal tendinopathy, both groups improved similarly at two and six weeks, but by twelve weeks the PRP group had significantly better pain and function scores. A larger proportion of PRP patients achieved a clinically meaningful improvement at that time point.¹⁸ A separate trial with two-year follow-up found that the improvement from a leucocyte-rich PRP injection was sustained over that period, while corticosteroid benefits were not maintained beyond about six months.¹⁹ PRP is not yet standard care everywhere, and insurance coverage varies, but the early data is encouraging for people who have not responded to exercise and education.

When conservative measures fail and a gluteal tendon tear is confirmed, surgical repair is an option. Both open and endoscopic (keyhole) approaches are used. A study tracking outcomes across different tear grades reported an overall clinical success rate of 90 percent, with success rates above 90 percent for lower-grade tears and around 77 percent for the most severe (grade 3) tears.²⁰ The main factor predicting worse surgical outcomes was fatty infiltration of the muscle, where the muscle tissue has been progressively replaced by fat due to long-standing tendon detachment. In a prospective study of endoscopic repair for full-thickness tears, pain scores dropped by more than half, abduction strength improved in the majority of patients, and the Trendelenburg limp resolved in all cases by two years, with no retears.²¹

Apophyseal Avulsions in Adolescents

Hip tendon injuries in teenagers look different from those in adults. In adolescents, the growth plates where tendons attach to the pelvis have not yet fused with the underlying bone. A sudden, forceful contraction, like a sprint start or a powerful kick, can pull a chunk of bone away from the pelvis at the tendon attachment point rather than tearing the tendon itself. These injuries are called apophyseal avulsion fractures, and the hip and pelvis are the most common location for them.

A review of 719 such fractures found that the average patient was about 14 or 15 years old, and roughly four out of five were boys. The three most common sites were the anterior inferior iliac spine (where the rectus femoris attaches), the anterior superior iliac spine (the sartorius attachment), and the ischial tuberosity (the hamstring origin).²² Most of these injuries heal with rest and activity modification, but large or displaced fragments sometimes require surgical fixation. If your teenager suddenly develops sharp hip or groin pain during a sports event and cannot bear weight, imaging of the pelvis is important to rule out an avulsion before assuming a simple muscle strain.

Tendons Versus Ligaments Around the Hip

A common source of confusion is the difference between tendons and ligaments in the hip region. Both are bands of dense connective tissue, and they sit close together, but they serve different roles. Tendons connect muscle to bone and transmit the force of muscle contraction. Ligaments connect bone to bone and limit joint motion to prevent dislocation. The hip has several strong ligaments, including the iliofemoral ligament (one of the strongest in the body), which restrains the hip from overextending, and the ischiofemoral ligament at the back.

In practice, tendons and ligaments in the hip work as a team. A cadaveric study examining hip stability after total hip replacement found that the iliofemoral ligament was the primary restraint to external rotation, while the conjoined tendon (where the gluteus minimus tendon and hip capsule blend together) was the most important restraint to internal rotation. Removing any single structure had a modest effect, but losing two or more structures significantly compromised joint stability.²³ This is one reason why surgical approaches to the hip are carefully planned to preserve as many of these structures as possible.

Protecting Your Hip Tendons Over Time

Tendon degeneration at the hip is largely a wear-related process, but that does not mean it is inevitable. The principle behind conservative management of early gluteal tendinopathy is protecting the tendon from excessive pulling and compressive forces while progressively increasing load through targeted exercise. Crossing your legs, lying on the affected side without a pillow between the knees, and habitual standing with your hip hitched to one side all increase compressive stress on the gluteal tendons against the trochanter. Awareness of these positions is a low-cost first step.

Progressive strengthening, particularly of the hip abductors and external rotators, builds the tendon’s tolerance for load over time. This is the same principle used in Achilles and patellar tendinopathy, and the evidence supports it at the hip as well. The catch is that loading must be graduated. Jumping straight into heavy resistance or high-impact activity with an irritated tendon usually makes things worse before they get better. A physical therapist familiar with tendon rehabilitation can help calibrate the starting point and progression. For most people, the tendons in the hip will never announce their presence at all. But when they do, knowing they exist and understanding what they respond to makes the difference between a problem that resolves in weeks and one that lingers for years.
