Gluteus medius tendinopathy

Anatomy: What does the gluteus medius do?

The gluteus medius muscle arises on the outside of the ilium (os ilium) and attaches with its tendon fibers to the greater trochanter of the femur (trochanter major). It is a central stabilizer of the pelvis when walking: in the standing leg phase, it prevents the pelvis from tipping to the opposite side (Trendelenburg sign). Together with the gluteus minimus and tensor fasciae latae (TFL), it acts as a hip abductor and controls the rotation and adduction forces.

• Function: abduction and stabilization of the pelvis
• Insertion: tendon plate on the greater trochanter
• Neighborhood: trochanteric bursa, iliotibial tract, gluteus minimus

Both tensile forces (due to muscle work) and pressure/compression forces (e.g. when the hip is strongly adducted or when lying on the side) act in the tendon region. This mechanical stress is partly responsible for the development and irritation of tendinopathy.

What is gluteus medius tendinopathy?

Gluteus medius tendinopathy is a degenerative or overload-related change in the tendon fibers of the greater trochanter. Microdamage, irritation and in some cases partial or rarely complete ruptures lead to pain and loss of function. Trochanteric bursitis and/or gluteus minimus involvement are often associated.

• Part of the Greater Trochanteric Pain Syndrome (GTPS) spectrum
• Middle-aged to older women are often affected
• Favored by long-term adduction postures and repeated overload

Typical symptoms

• Stabbing or burning pain on the outside of the hip, often radiating to the side of the thigh
• Tenderness over the greater trochanter
• Discomfort when sleeping on the side (particularly on the affected side)
• Pain when walking for long periods of time, climbing stairs, going uphill or when changing direction quickly
• Pain/weakness when standing on one leg; occasional limping gait
• Morning stiffness, start-up pain

A sudden, painful “snapping” or an acute loss of strength can indicate a partial rupture and should be checked by a doctor.

Causes and risk factors

Tendinopathy usually arises from a mismatch between the load and resilience of the tendon. Recurring tension and compression stimuli lead to micro-injuries that do not heal without sufficient regeneration. The tendon properties also change with increasing age.

• Training and everyday life: sudden increase in running volume, lots of stairs, standing/walking for long periods of time
• Posture and movement patterns: frequent crossing of legs, sitting for long periods with hips adducted, sleeping on the side without a pillow
• Biomechanics: Weakness of the hip abductors, lumbopelvic instability, leg axis deviation, leg length difference, foot misalignment
• Systemic factors: older age, hormonal changes (e.g. postmenopausal), obesity, diabetes, smoking
• Medications/strains: rarely influenced by fluoroquinolones or statins; monotonous overcoupling in sports (e.g. track running with curves)

Delimitation: What else could be behind it?

• Trochanteric bursitis
• Gluteus minimus tendinopathy
• Tensor fasciae latae irritation/tractus iliotibialis friction
• Lumbar spine problems (e.g. radicular pain)
• Hip osteoarthritis, femoroacetabular impingement (FAI)
• Stress fracture of the femoral neck (especially in runners, osteoporosis)
• Sacroiliac joint dysfunction, piriformis syndrome
• Meralgia paraesthetica (nerve irritation of the cutaneous femoris lateralis nerve)

Diagnostics in practice

It begins with a detailed anamnesis: location of pain, progression, stress context, previous treatments and accompanying illnesses. We then check gait, pelvic stability and abductor strength as well as provocative tests.

• Clinical tests: Pain on palpation at the trochanter, one-leg stance, Trendelenburg sign, resistance tests (abduction, external rotation), FABER test
• Ultrasound: assessment of the tendon, bursae, possibly partial tears; dynamic examination possible
• X-ray: assessment of bony structures, calcium deposits, signs of arthrosis
• MRI: if the diagnosis is unclear, persistent symptoms or suspected structural ruptures

Important: Imaging and symptoms do not always correlate directly. The diagnosis is based on the interaction of anamnesis, examination and targeted imaging.

Conservative therapy: First control the load, then specifically strengthen it

Conservative treatment is successful for most patients. The aim is to gradually reduce the pain-increasing compression and gradually increase the load on the tendon with individual exercise progression.

Time course: Frequent improvement within 6-12 weeks, but stable adaptation of the tendon usually takes 3-6 months. Patience and continuous, pain-adapted exercise control are crucial.

• Pain scale as a guide: Choose the load so that symptoms remain tolerable and subside within 24-48 hours.
• In the acute stage, more isometric holding exercises (30-45 seconds, 4-5 repetitions).
• As you progress, switch to slow, controlled eccentric-concentric exercises.

Interventional options: consider carefully

If pain persists for several weeks despite structured conservative therapy, additional measures can be considered. We discuss the benefits, risks and individual indications transparently.

• Ultrasound-guided infiltrations: Cortisone can relieve pain in the short term, but carries the risk of relapse and tendon damage; Use sparingly if carefully indicated.
• PRP (platelet-rich plasma): regenerative procedure with growing but heterogeneous evidence; Option for chronic courses after conservative exhaustion.
• ESWT (shock wave): often useful as a series for treatment-resistant tendinopathies.
• Barbotage/needling for calcified tendinopathies: decision on a case-by-case basis.

Important: Regenerative procedures do not guarantee healing. With careful patient selection and correct load control, they can be a useful addition.

When does an operation make sense?

Surgical treatment is particularly suitable for proven partial or full tears with significant functional impairment and if conservative therapy has been unsuccessful for several months. Procedures are e.g. B. endoscopic or open suture/refixation of the gluteus medius tendon, possibly combined with bursectomy and iliotibial band release.

• Indication: structural damage + persistent symptoms despite therapy
• Goal: Pain relief and restoration of abduction function
• Rehabilitation: phase-based program lasting several months with stress build-up

In our practice, the focus is on conservative treatment and pre-/post-operative support. If an operation is necessary, we coordinate with experienced partners.

Exercises and self-help: safe and targeted

The following exercises are examples and should be adapted to the individual pain status. Make sure you do it in a controlled manner, without any evasive movements and without a significant increase in symptoms the following day.

• Everyday tips: When sleeping on your side, put a pillow between your knees; Do not lie on the painful side.
• Stay active: walking, cycling in a low-pain area; If necessary, temporarily pause running training and then gradually resume it later.
• Pain management: observe the 24-48 hour rule; If there is significant deterioration, reduce the load.

Course and prognosis

Most cases improve with consistent conservative treatment. The tendon slowly adapts. Initial progress is often noticeable after a few weeks; stable results often take a few months. Relapses are possible if stress control is not adhered to or if significant risk factors persist.

• Good prospects with structured exercise therapy
• Relapse prevention through long-term strengthening and everyday modifications
• If symptoms persist, repeat diagnostics and adjust therapy

Prevention

• Regular strengthening of gluteus medius/minimus
• Training build-up gradually (10-20% rule), sufficient regeneration
• Check running technique/gait, step width not too narrow
• Suitable footwear, insoles if necessary
• Avoid sitting with your legs crossed for long periods of time

When should you seek medical advice?

• Severe or nocturnal pain that does not subside for weeks
• Significant weakness when abducting or sudden “runaway” of strength
• Acute symptoms after a fall/trauma
• Uncertainty regarding diagnosis or appropriate exercises
• Accompanying neurological symptoms (e.g. numbness) or systemic warning signs
