Gluteus Medius/Minimus Tendinopathy

Gluteus Medius/Minimus: A Physiotherapy Guide

What Is Gluteus Medius/Minimus Tendinopathy?

Gluteus medius and minimus tendinopathy is a degenerative condition affecting the tendons that attach the gluteus medius and gluteus minimus muscles to the greater trochanter of the femur. Once broadly labelled "trochanteric bursitis," the condition is now understood to be primarily a tendinopathy rather than an inflammatory bursitis, with imaging studies consistently showing tendon pathology as the dominant finding in patients presenting with lateral hip pain (Mellor et al., BMJ, 2018). The hallmark symptom is pain over the outside of the hip that worsens with weight-bearing activities such as walking, stair climbing, and lying on the affected side at night.

Gluteal tendinopathy falls under the broader clinical umbrella of Greater Trochanteric Pain Syndrome (GTPS), which affects an estimated 10 to 25 percent of the general population. It is particularly common among postmenopausal women, runners, and individuals who have recently increased their training volume. Unlike acute injuries that heal within a predictable inflammatory timeline, tendinopathy involves a failed healing response in which the collagen architecture of the tendon becomes disorganized, mechanically weaker, and chronically painful. Fortunately, research published in the past decade has established that structured physiotherapy-led exercise programs produce outcomes that are superior to corticosteroid injections and watchful waiting, making physical therapy the first-line treatment for this condition (Mellor et al., BMJ, 2018).

Prevalence

Lateral hip pain driven by gluteal tendinopathy is one of the most frequent musculoskeletal complaints seen in physiotherapy clinics. Population studies estimate that GTPS has a point prevalence of 15 percent in women aged 50 to 79, and the condition accounts for a significant proportion of hip-related referrals to both physiotherapy and orthopedic services. Because the condition is chronic and often bilateral, it can substantially affect quality of life, sleep, and participation in physical activity.

Anatomy of the Gluteus Medius and Gluteus Minimus

Understanding the anatomy of the lateral hip is essential for appreciating why these tendons are vulnerable to overload and how physiotherapy targets the problem.

• The Gluteus Medius
• The gluteus medius is a broad, fan-shaped muscle that originates from the outer surface of the ilium, between the iliac crest above and the posterior and anterior gluteal lines. It converges into a strong, flattened tendon that inserts onto the lateral and superoposterior facets of the greater trochanter. The muscle is the primary hip abductor and plays a critical role in stabilizing the pelvis during single-leg stance activities such as walking and running. Its tendon is composed of dense Type I collagen fibers arranged in parallel, which gives it the capacity to store and release elastic energy during gait. When compressive or tensile loads exceed the tendon's adaptive capacity, the collagen matrix begins to break down, initiating the tendinopathic process.
• The Gluteus Minimus
• The gluteus minimus lies deep to the gluteus medius. It originates from the outer surface of the ilium between the anterior and inferior gluteal lines and inserts onto the anterior facet of the greater trochanter. Its primary function is hip abduction and internal rotation, and it acts as a dynamic stabilizer of the femoral head within the acetabulum during weight-bearing. Because the gluteus minimus tendon wraps around the anterior aspect of the greater trochanter at a relatively acute angle, it is exposed to significant compressive loading against the bone, a mechanical environment that predisposes it to insertional tendinopathy (Ilizaliturri et al., Arthroscopy, Sports Medicine, and Rehabilitation, 2022).
• The Trochanteric Bursa Complex
• Several bursae surround the greater trochanter, including the subgluteus maximus bursa, the subgluteus medius bursa, and the subgluteus minimus bursa. These fluid-filled sacs normally reduce friction between the tendons and the bony prominence. In gluteal tendinopathy, secondary irritation of the bursae is common, which historically led clinicians to attribute lateral hip pain to "bursitis." Modern imaging research, however, has shown that isolated bursitis without underlying tendon pathology is rare, and that bursal distension is almost always a secondary phenomenon accompanying tendon degeneration.

Causes and Risk Factors

Gluteal tendinopathy develops when the mechanical load applied to the tendons exceeds their capacity to adapt and repair. This overload can result from a single dramatic increase in activity or, more commonly, from sustained cumulative loading patterns over months or years.

• Biomechanical Overload and Compressive Loading
• The most important pathomechanical driver of gluteal tendinopathy is combined tensile and compressive loading at the tendon insertion. Activities that place the hip in an adducted position, such as crossing the legs, standing with the hip hitched to one side, or lying on the affected side, increase compression of the gluteal tendons against the greater trochanter. Running on cambered surfaces, single-leg balance activities with poor pelvic control, and prolonged sitting with legs crossed are all common provocative factors. Research into tendon load management has highlighted that it is not simply the magnitude of load but the ratio of load to recovery that determines whether a tendon adapts positively or begins to degenerate (Escriche-Escuder et al., BMJ Open, 2020).
• Hormonal and Age-Related Changes
• The condition is two to four times more prevalent in women than men, and incidence peaks during and after menopause. Declining estrogen levels are thought to reduce tendon collagen synthesis, decrease water content in the tendon matrix, and impair the tendon's ability to remodel in response to load. These hormonal changes partly explain why postmenopausal women are disproportionately affected, even in the absence of a clear increase in physical activity.
• Training Errors and Sudden Load Spikes
• Runners and recreational athletes frequently develop gluteal tendinopathy after abrupt increases in training volume, intensity, or hill work. The gluteal tendons must absorb forces of up to three times body weight during running, and a poorly managed increase in weekly mileage can overwhelm the tendon's remodeling capacity. Similarly, individuals returning to exercise after a period of deconditioning, such as after illness, pregnancy, or a sedentary winter, are at elevated risk.
• Hip Joint Pathology and Altered Biomechanics
• Osteoarthritis of the hip, femoroacetabular impingement, and leg-length discrepancy can alter gait mechanics and redistribute forces across the lateral hip. In these cases, gluteal tendinopathy may develop as a secondary condition driven by compensatory movement patterns.
• Sedentary Behavior and Deconditioning
• Paradoxically, underloading the gluteal muscles can be just as harmful as overloading them. Prolonged sitting leads to disuse atrophy of the gluteus medius and minimus, reducing the tendon's load tolerance. When the deconditioned individual then attempts a burst of activity, such as a long walk or a weekend hike, the tendons are ill-prepared for the demand, and the tendinopathic cycle begins.

Why Physiotherapy Is the First-Line Treatment

The landmark LEAP trial (Lateral hip pain: Education And exercise for Persistent gluteal tendinopathy) published in the BMJ by Mellor and colleagues in 2018 provided the strongest evidence to date that physiotherapy-led education and exercise is superior to both corticosteroid injection and a wait-and-see approach for gluteal tendinopathy. At the primary eight-week endpoint, 78.6 percent of participants in the education-plus-exercise group reported global improvement, compared to 58.3 percent in the corticosteroid group and just 51.5 percent in the wait-and-see group. Critically, the advantage of the exercise group persisted and widened at the 52-week follow-up, while the corticosteroid group lost its initial gains and performed no better than the wait-and-see group at one year (Mellor et al., BMJ, 2018).

Why Cortisone Injections Are Not a Long-Term Solution

Corticosteroid injections can provide rapid short-term pain relief by suppressing local inflammation, but they do nothing to address the underlying structural weakness of the tendon. Repeated injections have been associated with tendon weakening, fat infiltration of the gluteal muscles, and poorer long-term outcomes compared to exercise-based rehabilitation. The LEAP trial demonstrated that patients who received corticosteroid injections showed a pattern of initial improvement followed by regression, whereas the exercise group experienced sustained and progressive improvement. For this reason, current clinical guidelines recommend reserving corticosteroid injections for short-term pain management in severe cases and prioritizing progressive loading exercises as the definitive treatment.

The Physiotherapy Advantage

Physiotherapy addresses gluteal tendinopathy at its root by restoring the tendon's load-bearing capacity through carefully progressed strengthening exercises. A skilled physiotherapist also identifies and corrects the biomechanical factors, postural habits, and training errors that contributed to the condition in the first place. Education, a core component of the LEAP protocol, empowers patients to manage their condition independently by understanding what aggravates and what helps their tendons (Mellor et al., BMC Musculoskeletal Disorders, 2016).

Recovery Timeline: What to Expect

Tendon healing is a slow biological process, and patients who understand this from the outset tend to have better outcomes because they maintain adherence to their exercise program rather than seeking quick fixes.

• Weeks 1 to 4: Pain Education and Load Management
• The initial phase focuses on reducing tendon irritability by modifying aggravating activities and beginning gentle isometric exercises. Patients learn to avoid sustained hip adduction postures, such as crossing the legs or sleeping on the affected side without a pillow between the knees. Isometric hip abduction holds, performed with the hip in a neutral or mildly abducted position, help activate the gluteal muscles without imposing harmful compressive loads on the tendon. Most patients begin to notice a reduction in night pain and resting discomfort within the first two to three weeks.
• Weeks 4 to 8: Progressive Strengthening
• As pain settles, the program progresses to isotonic strengthening exercises in side-lying, standing, and functional positions. Exercises such as side-lying hip abduction, standing hip hitch, and supported single-leg stance are introduced with load and volume incrementally increased according to the patient's symptom response. The LEAP trial used a criterion-based progression model in which patients advanced to the next exercise level only when they could complete the current level with acceptable pain levels, typically no more than 3 out of 10 on a numerical pain rating scale (Mellor et al., BMJ, 2018).
• Weeks 8 to 12: Functional Loading and Return to Activity
• The rehabilitation program shifts toward functional and sport-specific tasks that replicate the demands of the patient's daily life or athletic pursuits. This may include step-ups, lunges, single-leg squats, and graduated return to running or hiking. Load progression follows the principle that the tendon must be exposed to progressively greater forces to stimulate adaptive remodeling of its collagen matrix (Escriche-Escuder et al., BMJ Open, 2020).
• Months 3 to 6 and Beyond: Maintenance and Full Recovery
• Complete resolution of symptoms in gluteal tendinopathy typically takes three to six months, though some patients with long-standing tendinopathy may require up to twelve months of consistent rehabilitation. Even after symptoms resolve, ongoing maintenance exercises performed two to three times per week are recommended to preserve tendon health and prevent recurrence. Patients who remain adherent to a long-term loading program have the best outcomes, with research showing that the benefits of exercise continue to accrue for at least twelve months after initiating treatment (Mellor et al., BMJ, 2018).

Treatment Approaches at Vaughan Physiotherapy

At Vaughan Physiotherapy in Thornhill, our evidence-based approach to gluteal tendinopathy draws directly on the protocols validated in the LEAP trial and the latest tendon rehabilitation research. Treatment is individualized to each patient's severity, functional goals, and stage of tendon pathology.

• Comprehensive Assessment
• Your first appointment includes a thorough subjective history, biomechanical assessment, and clinical testing to confirm the diagnosis of gluteal tendinopathy and rule out other sources of lateral hip pain, including hip joint pathology, lumbar referred pain, and meralgia paresthetica. Special tests such as the single-leg stance test, the FABER test, and resisted hip abduction are used to reproduce and localize the pain.
• Education and Activity Modification
• Education is a cornerstone of our treatment approach, as the LEAP trial protocol emphasized (Mellor et al., BMC Musculoskeletal Disorders, 2016). We teach patients how compressive loading aggravates the tendon and provide practical strategies for modifying daily activities: avoiding leg crossing, using a pillow between the knees at night, standing with equal weight through both legs, and managing training volume. Understanding the "why" behind these modifications improves adherence and speeds recovery.
• Progressive Loading ProgramThe therapeutic exercise program progresses through four stages designed to rebuild the tendon's capacity:
  • Stage 1 (Isometric Loading): Isometric hip abduction holds at various angles, typically 5 repetitions of 30 to 45 seconds, performed daily. These exercises reduce pain and begin to stimulate tendon adaptation without imposing harmful compressive forces.
  • Stage 2 (Isotonic Strengthening): Exercises such as side-lying hip abduction, standing hip hitch, and bridging with a resistance band are introduced with progressive increases in load every one to two weeks, guided by symptom response.
  • Stage 3 (Functional Strengthening): Step-ups, split squats, single-leg Romanian deadlifts, and lateral band walks are incorporated to build strength in positions that replicate daily activities and sport demands.
  • Stage 4 (Energy Storage and Return to Sport): For athletes, plyometric and running-specific drills are introduced to restore the tendon's capacity to store and release elastic energy. Progression criteria are based on objective measures of strength, endurance, and pain response to ensure safe return to full activity (Escriche-Escuder et al., BMJ Open, 2020).
• Manual Therapy and Adjunct Treatments
• While exercise is the primary intervention, manual therapy techniques including soft tissue release of the iliotibial band, tensor fasciae latae, and hip flexors can help reduce pain and improve range of motion in the early stages of rehabilitation. For patients who are not progressing as expected with exercise alone, extracorporeal shockwave therapy has shown promising results, with a recent study demonstrating sustained improvements in pain and function at twelve months in patients with gluteal tendon pathology (Fulceri et al., Life, 2024).
• Gait Retraining
• For runners and walkers, gait analysis and retraining can address biomechanical factors that increase lateral hip loading. Common modifications include increasing step rate (cadence), reducing crossover gait patterns, and strengthening hip external rotation to improve pelvic stability during the stance phase of running.

Prevention Strategies

Preventing gluteal tendinopathy, or preventing its recurrence after successful treatment, relies on maintaining tendon health through consistent loading, avoiding known risk factors, and addressing modifiable biomechanical contributors.

• Maintain Hip Abductor Strength
• The single most effective prevention strategy is maintaining adequate strength in the gluteus medius and minimus through regular resistance training. Exercises such as side-lying hip abduction, clamshells with resistance, standing hip hitch, and single-leg balance activities performed two to three times per week provide the mechanical stimulus that tendons need to maintain their structural integrity.
• Manage Training Load Progressions
• The "10 percent rule," which recommends increasing weekly training volume by no more than 10 percent, provides a useful general guideline for runners and recreational athletes. Sudden spikes in volume, intensity, or hill training should be avoided, particularly after periods of reduced activity.
• Optimize Sleep and Recovery Posture
• Side sleepers should place a firm pillow between their knees to prevent hip adduction and compression of the lateral hip structures. Sleeping on the unaffected side or on the back is generally more comfortable and reduces nocturnal tendon irritation.
• Avoid Prolonged Compressive Postures
• Consciously avoiding habitual leg crossing, prolonged standing with weight shifted to one hip, and sitting in low, deep chairs that force the hip into deep flexion and adduction can significantly reduce daily compressive loading on the gluteal tendons.
• Address Systemic Factors
• Maintaining a healthy body weight reduces the absolute load transmitted through the gluteal tendons during weight-bearing activities. For postmenopausal women, discussing hormonal health with a physician and ensuring adequate intake of Vitamin C, which is essential for collagen synthesis, may support tendon health.

Frequently Asked Questions

• What is the difference between gluteal tendinopathy and trochanteric bursitis?
• For many years, lateral hip pain was attributed almost exclusively to inflammation of the trochanteric bursa, hence the diagnosis of "trochanteric bursitis." However, modern imaging studies, including MRI and ultrasound, have shown that the majority of patients with lateral hip pain have degenerative changes in the gluteus medius or minimus tendons, with or without secondary bursal irritation. The term Greater Trochanteric Pain Syndrome (GTPS) is now preferred as an umbrella diagnosis, and gluteal tendinopathy is recognized as the primary pathology in most cases. Treatment focuses on rehabilitating the tendon rather than simply targeting the bursa.
• Can gluteal tendinopathy heal on its own without treatment?
• While mild cases may improve with activity modification and time, research shows that a wait-and-see approach produces inferior outcomes compared to structured physiotherapy. In the LEAP trial, only 51.5 percent of patients in the wait-and-see group reported global improvement at eight weeks, compared to 78.6 percent in the education-plus-exercise group (Mellor et al., BMJ, 2018). Without targeted strengthening, the underlying tendon weakness persists and the condition often becomes recurrent or chronic.
• Is it safe to exercise with gluteal tendinopathy?
• Yes, exercise is not only safe but is the most effective treatment. The key is selecting exercises that load the tendon appropriately without excessive compression. Isometric exercises are typically well-tolerated even in irritable tendons and can actually have an analgesic effect. As pain decreases, progressive strengthening exercises rebuild the tendon's capacity. Activities that should be temporarily modified or avoided include deep stretching of the hip abductors, prolonged side-lying on the affected hip, and high-impact activities that provoke significant pain.
• How long does it take to recover from gluteal tendinopathy?
• Most patients experience meaningful improvement within 8 to 12 weeks of beginning a structured exercise program, but full recovery typically takes 3 to 6 months. Patients with long-standing symptoms, significant tendon degeneration on imaging, or multiple failed prior treatments may require up to 12 months of rehabilitation. Consistency with the home exercise program is the single most important predictor of recovery speed.
• Should I get an MRI for lateral hip pain?
• An MRI is not always necessary to diagnose gluteal tendinopathy. A skilled physiotherapist can make a confident clinical diagnosis based on the pattern of symptoms and physical examination findings. However, imaging may be helpful when the diagnosis is uncertain, when symptoms are not responding to treatment as expected, or when there is a need to rule out other conditions such as hip joint osteoarthritis, stress fracture, or labral tear.
• Can shockwave therapy help with gluteal tendinopathy?
• Extracorporeal shockwave therapy (ESWT) has shown promising results as an adjunct treatment for gluteal tendinopathy. A 2024 study found that combined focused and radial shockwave therapy produced sustained improvements in pain and function at 12-month follow-up in patients with gluteal tendon pathology (Fulceri et al., Life, 2024). At Vaughan Physiotherapy, we may recommend shockwave therapy for patients who have not achieved adequate progress with exercise alone, always in combination with a progressive loading program rather than as a standalone treatment.
• Will a cortisone injection cure my lateral hip pain?
• Cortisone injections can provide rapid short-term relief, but they do not address the underlying tendon pathology and are associated with poorer long-term outcomes compared to exercise therapy. The LEAP trial showed that the corticosteroid injection group lost its initial gains by 12 months and performed no better than the wait-and-see group, while the exercise group maintained superior outcomes (Mellor et al., BMJ, 2018). Current evidence supports using cortisone injections only as a short-term bridge to enable participation in rehabilitation when pain levels are otherwise prohibitive.
