Osteoarthritis is a common disabling condition that causes joint pain and stiffness caused by the gradual erosion of cartilage. Hip osteoarthritis is a common form of osteoarthritis that causes restricted locomotor activity and functional disability, and may progress to the point where joint replacement is needed. Hip osteoarthritis is a major global public-health burden. <ref name=":2" />


Hip osteoarthritis mainly affects the articular cartilage, as well as causing changes to the subcondral bone, synovium, ligaments and capsule.<ref name=":6">Cooper C, Javaid MK, Arden N.

== Clinically relevant anatomy  ==
== Epidemiology ==
For detailed information, see the [[Hip Anatomy|hip anatomy page]].
Globally, from 1990 to 2019, the age-standardized incidence rate of hip osteoarthritis increased from 17.02 per 100,000 persons to 18.70 per 100,000 persons. The burden of hip osteoarthritis has increased in almost all countries over the past 30 years, this increasing trend is expected to continue, due to the rapid aging of the world’s population.

=== Prevalence ===
* Osteoarthritis is the most common cause of hip pain in older adults (older than 50 years of age).
According to the Centers for Disease Control and Prevention, lifetime risk for symptomatic hip OA is 18.5% for men and 28.6% for women<ref name=":8" />.  
* Prevalence rates for adult hip OA range from 0.4% to 27%.

== Pathology ==
[[File:Hip OA schematic.jpeg|thumb|Severe OA 1. osteophytes 2. subchondral thickening 3. cyst 4. jt space narrowing|alt=]]Osteoarthritis is distinguished by an active progressive alteration of the whole synovial joint, being due to a combination of mechanical, inflammatory and metabolic factors. It is caused by an imbalance between the destruction and repair of the affected tissues. The disease affects the


=== Primary osteoarthritis versus Secondary osteoarthritis ===
* Hyaline cartilage: loses its structural integrity due to composition changes.
In primary OA, the disease is of idiopathic origin (no known cause) and usually affects multiple joints in a relatively elderly population. Secondary OA usually is a monoarticular condition and develops as a result of a defined disorder affecting the joint articular surface (eg, trauma). or from abnormalities of joint eg acetabular displasia. Pistol grip deformities are seen in some cases, mostly linked with [[Slipped Capital Femoral Epiphysis|slipped upper femoral epiphysis]]. Although seen as a specific condition, it is often linked with metabolic abnormalities.<ref>Harris WH. Etiology of osteoarthritis of the hip. Clinical orthopaedics and related research 1986; 213:20-33.</ref>
* Subchondral bone
* Joint capsule
* Synovium
* Ligaments and the periarticular muscles.


=== Risk factors ===
== Risk Factors ==
*Previous hip trauma (causing injury or [[Hip Fracture|fracture]]) - mostly resulting in unilateral hip osteoarthritis
Risk factors that increase the likelihood of developing osteoarthritis of the hip are
*Primary inflammatory arthritis (e.g. [[Rheumatoid Arthritis|rheumatoid arthritis]], [[Ankylosing Spondylitis|ankylosing spondylitis]])
*Joint morphology
*Genetics
*Congenital and developmental hip disease (e.g. congenital hip dislocation, [[Legg-Calve-Perthes Disease|Perthe's disease]], [[Slipped Capital Femoral Epiphysis|slipped upper femoral epiphysis]], [[Hip Dysplasia|developmental hip dysplasia]])
*Subchondral bone defects
*[[Obesity]] - mostly resulting in bilateral hip osteoarthritis
*Occupation causing excessive strain on hips (e.g. manual labor causing repeated loading)
*Increase in age
*Gender (female > male)
*Sport (higher impact sport at a younger age can cause increase in articular cartilage strength, where low impact sport do not change the composition of the cartilage)
*Menopause
*Metabolic diseases and acromegaly
*Sedentary lifestyle
*[[Femoroacetabular Impingement|Femoroacetabular impingement]]
*[[Avascular necrosis of the femoral head|Avascular necrosis]]
*Ethnicity - 80-90% less prevalent in the Asian population when compared to the Caucasian population in the USA
*Diet - low Vitamin D, C and K levels

=== Special investigations ===
== Management ==
Hip osteoarthritis can be diagnosed by clinical presentation only, but special investigation (e.g. x-rays) are vital to monitor the progression of the disease. The video below explains the xray changes seen in hip OA
A [[Biopsychosocial Model|biopsychosocial approach]] offers the best outcome.<ref name=":1" /> A multidisciplinary team may be involved including: doctors, physiotherapists, dietitians, and occupational therapists.

== Medical management  ==


Medical management of hip osteoarthritis focuses on treating the symptoms. Effective disease-modifying interventions have not been established yet, thus a major focus should be on primary prevention strategies.<ref name=":0" /> The optimal management of hip osteoarthritis consists of a combination of pharmaceutical and non-pharmaceutical treatment modalities. It is also important to take the patient's wishes and expectations into consideration.  
# OA management includes patient education combined with exercise and/or manual therapy. Education should include teaching activity modification, exercise <ref>Dalmas I, Agius TP, Sciriha A. Core muscle strengthening exercises in the management of hip osteoarthritis: outcomes of a 12-week programme. European Journal of Physiotherapy. 2023 Mar 27:1-8.</ref>, supporting weight reduction when overweight (see below), and methods of unloading the arthritic joints.
# Management includes providing impairment-based functional, gait, and balance training, including the proper use of assistive devices (canes, crutches, walkers), to patients with hip osteoarthritis and activity limitations, balance impairment, and/or gait limitations when associated problems are observed.<ref name=":3" />
# Offer topical or oral [[NSAIDs|nonsteroidal anti-inflammatory drugs]] in those without contraindications.
# Intra-articular steroid injections provide short-term pain relief and duloxetine has demonstrated efficacy. Opiates should be avoided.<ref name=":7" />


=== Primary prevention ===
* Patient education - especially in primary health care
* Muscle strengthening
* Joint preserving surgery prior to onset of hip osteoarthritis/early in disease process
* Modification of risk factors:
** Weight control
** Switching from high-impact to low-impact activities
** Minimization of pain aggravating activities
<ref name=":0" /><ref name=":9" /> 


=== Pharmacological management ===
* Symptom-relief drugs:
** Treatment of choice: Paracetamol
** NSAIDs:
*** Low doses and duration due to side effects
*** To be used for patients not responding well to paracetamol
*** Patients with high risk of developing gastrointestinal side effects:  Non-selective NSAID together with a gastroprotective agent OR selective COX-r inhibitor
** Duloxetine - works on central nervous system to inhibit pain
** Opioids:
*** Tramadol (non-narcotic opioid)
*** Can be used in combination with paracetamol
*** Alternative if not NSAIDS and COX-2 inhibitors are not effective or contraindicated
** Intra-articular injections:
*** Corticosteroids
**** Consider when patients are having flare-ups and is not responding to paracetamol and NSAIDs.
*** Platelet-rich plasma (evidence still lacking)
** Hyaluronic acid - Evidence still lacking for effectiveness in the management of hip osteoarthritis
* Disease-modifying osteoarthritis drugs (research on this topic still ongoing)

For those who are overweight ([[Body Mass Index|body mass index]] [BMI] ≥25 kg/m2 ) or obese (BMI ≥30 kg/m2 ), a minimum weight loss target of 5–7.5% of body weight is recommended. It is beneficial to achieve a greater amount of weight loss given that a relationship exists between the amount of weight loss and symptomatic benefits. Weight loss should be combined with exercise for greater benefits. For people of healthy body weight, education about the importance of maintaining healthy body weight is essential.
90% of total hip replacements are done as a result of end-stage hip osteoarthritis. It is a successful orthopaedic procedure in the treatment of hip osteoarthritis, when conservative management has failed and is highly effective at relieving symptoms.  


==== Hip resurfacing ====
'''Surgical interventions:''' [[Total Hip Replacement|Total hip replacement]] - The option in patients with symptomatic and radiographic osteoarthritis characterized by refractory pain and disability; [[Osteotomy]] and hip resurfacing - Should be considered in younger patients with symptomatic secondary osteoarthritis due to acetabular dysplasia, femoroacetabular impingement, varus or valgus deformity<ref name=":6" />.
This is normally done for the younger, more active population with painful dysplasia and deformities.  


==== [[Osteotomy|Hip osteotomy]] ====
== Physiotherapy Management ==
An osteotomy is preformed to realign the hip joint to lessen pressure. This is not a common in the treatment of osteoarthritis.
Physiotherapy plays in major role in the management of patients with hip osteoarthritis. The goal is to  improve strength, mobility and increase range of motion. Physiotherapy also helps relieve pain and restores normal movement in the hip and legs and also addresses pain management and functional adaptions. Patient-specific exercise programmes has shown to decrease pain and improve function in hip osteoarthritis.<ref name=":0" /><ref name=":1">Bennell K.

* exercises,
* ice and heat,
* taping,
* stretching
* improve their stance and balance
* aid ability to peform ADL's.
A [[Biopsychosocial Model|biopsychosocial approach]] to the management of hip osteoarthritis leads to patients experiencing less anxiety, even though the condition may not always improve.<ref name=":1" /> It is important to consider the rest of the multidisciplinary team as well. Dietitians, occupational therapists and psychologists can play an important part in the management of hip osteoarthritis.

We strongly recommend weight management for people with knee and/or hip OA. For those who are overweight (body mass index [BMI] ≥25 kg/m2 ) or obese (BMI ≥30 kg/m2 ), a minimum weight loss target of 5–7.5% of body weight is recommended. It is beneficial to achieve a greater amount of weight loss given that a relationship exists between the amount of weight loss and symptomatic benefits. Weight loss should be combined with exercise for greater benefits. For people of healthy body weight, education about the importance of maintaining healthy body weight is essential.

Introduction[edit | edit source]

Hip OA diagram

Osteoarthritis is a common disabling condition that causes joint pain and stiffness caused by the gradual erosion of cartilage. Hip osteoarthritis is a common form of osteoarthritis that causes restricted locomotor activity and functional disability, and may progress to the point where joint replacement is needed. Hip osteoarthritis is a major global public-health burden. [1]

  • For people with hip arthritis, physiotherapy may assist in conditioning and obtaining endurance of the surrounding muscles that support the joint.
  • A long term approach to the management of a hip OA should include some type of regular physical therapy or conditioning program.

Epidemiology[edit | edit source]

Globally, from 1990 to 2019, the age-standardized incidence rate of hip osteoarthritis increased from 17.02 per 100,000 persons to 18.70 per 100,000 persons. The burden of hip osteoarthritis has increased in almost all countries over the past 30 years, this increasing trend is expected to continue, due to the rapid aging of the world’s population.

  • Osteoarthritis is the most common cause of hip pain in older adults (older than 50 years of age).
  • Prevalence rates for adult hip OA range from 0.4% to 27%.
  • The reported prevalence of hip OA shows great variability, with men showing higher prevalence of radiographic hip OA.[1][2]
  • Lifetime risk for symptomatic hip OA is 18.5% for men and 28.6% for women[3].
  • Research suggest that there are a 25% risk of developing hip osteoarthritis for people who live to the age of 85,[4]

Pathology[edit | edit source]

Severe OA 1. osteophytes 2. subchondral thickening 3. cyst 4. jt space narrowing

Osteoarthritis is distinguished by an active progressive alteration of the whole synovial joint, being due to a combination of mechanical, inflammatory and metabolic factors. It is caused by an imbalance between the destruction and repair of the affected tissues. The disease affects the

  • Hyaline cartilage: loses its structural integrity due to composition changes.
  • Subchondral bone
  • Joint capsule
  • Synovium
  • Ligaments and the periarticular muscles.

Risk Factors[edit | edit source]

Risk factors that increase the likelihood of developing osteoarthritis of the hip are

Diagnosis[edit | edit source]

Advanced OA of a hip.

The following criteria should be used to classify adults over the age of 50 with hip OA:

  1. Moderate anterior or lateral hip pain during weight-bearing activities
  2. Morning stiffness less than 1 hour in duration after wakening
  3. Hip internal rotation range of motion less than 24° or internal rotation and hip flexion 15° less than the nonpainful side, and/or increased hip pain associated with passive hip internal rotation.[2]

Radiographic evidence: joint space narrowing, marginal osteophytes, subchondral sclerosis, and bone cysts.[6][7].

Clinical Presentation[edit | edit source]

Hip OA - Elderly lady

Pain characteristics:

  • Slowly progressive hip pain, or hip-related groin pain radiating into the thigh, buttocks or knee.
  • The pain can be worse at night, at rest or with strenuous activity, reducing the range of motion and limiting walking distance. It can be associated with stiffness particular in the morning or after rest.

Other symptoms include locking, grinding and joint instability, fatigue and pain-related psychological stress.[8]

Physical Examination[edit | edit source]

Measuring ROM hip

A physical examination includes (Also also hip examination)

  • Observation
  • Subjective interview:
    • Complaints of pain, deformity, stiffness and/or limp
    • Previous history linked to hip pain (congenital or childhood problems, previous trauma)
  • Physical examination in Standing and Supine (look for leg length discrepancy, antalgic gait and Trendelenberg gait)
  • Objective observation (posture, deformities, muscle atrophy)
  • Palpation:
    • Tenderness at the hip
    • Pain and sensitivity over greater trochanter
  • Range of motion:
    • Early signs of hip osteoarthritis is limited abduction and rotation. As the disease progresses, flexion, extension and adduction becomes more difficult.
    • Normally painful at end of available range of motion
  • Crepitis with movement[9][10][11]

Five variables for detecting hip osteoarthritis are:

  1. Self-reported squatting as an aggravating factor
  2. Active hip flexion causing lateral hip pain
  3. Hip Quadrant test with adduction causing lateral hip or groin pain
  4. Active hip extension causing pain
  5. Passive internal rotation of less than or equal to 25°

If there are 3/5 variables present, the chance of having OA is 68%. With 4-5/5 the chance increases to 91%. The variables are positive when there’s pain or a limited range of motion in the tests.[12]

Management[edit | edit source]

A biopsychosocial approach offers the best outcome.[13] A multidisciplinary team may be involved including: doctors, physiotherapists, dietitians, and occupational therapists.

Management of hip osteoarthritis varies according to the severity of the condition. A combination of pharmaceutical and non-pharmaceutical modalities is recommended for the optimal management of the condition. Physiotherapy plays an important role in customized exercise programmes for patients living with hip osteoarthritis.

  1. OA management includes patient education combined with exercise and/or manual therapy. Education should include teaching activity modification, exercise [14], supporting weight reduction when overweight (see below), and methods of unloading the arthritic joints.
  2. Management includes providing impairment-based functional, gait, and balance training, including the proper use of assistive devices (canes, crutches, walkers), to patients with hip osteoarthritis and activity limitations, balance impairment, and/or gait limitations when associated problems are observed.[2]
  3. Offer topical or oral nonsteroidal anti-inflammatory drugs in those without contraindications.
  4. Intra-articular steroid injections provide short-term pain relief and duloxetine has demonstrated efficacy. Opiates should be avoided.[7]



Weight management – Hip OA[15](RACPG 2018 guidelines): We strongly recommend weight management for people with hip OA. For those who are overweight (body mass index [BMI] ≥25 kg/m2 ) or obese (BMI ≥30 kg/m2 ), a minimum weight loss target of 5–7.5% of body weight is recommended. It is beneficial to achieve a greater amount of weight loss given that a relationship exists between the amount of weight loss and symptomatic benefits. Weight loss should be combined with exercise for greater benefits. For people of healthy body weight, education about the importance of maintaining healthy body weight is essential.

Surgical interventions: Total hip replacement - The option in patients with symptomatic and radiographic osteoarthritis characterized by refractory pain and disability; Osteotomy and hip resurfacing - Should be considered in younger patients with symptomatic secondary osteoarthritis due to acetabular dysplasia, femoroacetabular impingement, varus or valgus deformity[8].

Physiotherapy Management[edit | edit source]

Physiotherapy plays in major role in the management of patients with hip osteoarthritis. The goal is to  improve strength, mobility and increase range of motion. Physiotherapy also helps relieve pain and restores normal movement in the hip and legs and also addresses pain management and functional adaptions. Patient-specific exercise programmes has shown to decrease pain and improve function in hip osteoarthritis.[4][13]

Education

  • Role of physiotherapy and expected outcomes of physiotherapy interventions
  • Importance of weight reduction (combination of diet and exercise)
  • Self-management of pain: Use of modalities such as heat and ice; Relaxation techniques; Coping strategies; Exercise[4][9][16]

Assistive devices

  • Mobility assistive devices like walking sticks/canes, crutches, or walking frames can improve mobility and independence of the patient. Occupational therapy also plays a role here, as they often also assists the patients with functional assistive devices like a long-handled reacher to pick up low-lying things, which will helps to avoid movements that may cause pain.
  • The RACPG 20188 guidelines Assistive walking device – Hip OA[15] It may be appropriate to offer an assistive walking device (eg cane) for some people with knee and/or hip OA, depending on a person’s preference and capability.

Exercise therapy

Hip Theraband.png

Exercise therapy is an effective treatment modality for hip osteo-arthrosis.[13] Specific exercises can increase range of motion and flexibility, as well as strengthen the muscles of the hip and leg. Physiotherapists work together with the patient to develop an individualized, customized exercise program that meets the needs and lifestyle of the patient.[13][16] The benefits of exercise can assist the patients in their self-management of hip osteoarthritis.

  • Hydrotherapy is effective in the management of hip osteoarthritis. The combination of buoyancy and the reduction of gravity greatly assists patients that are struggling to weight-bear as a result of the pain from the hip osteoarthritis.[16]
  • A 2016 study of 210 people with hip OA found that those who participated in a 12-week exercise program had less pain and more mobility than the placebo or no-treatment groups.[17]
  • A study on a 6 week education and exercise programme has shown significant and sustained improvements in pain and disability on patients wait-listed for joint replacement surgery. Further positive results included improvements in function, knowledge and psycho-social aspects.[18] Clinical trials further suggest that it can postpone the need of total hip replacement surgery.[16]
Hip abduction exercise

The RACPG 20188 guidelines recommend as per below

1.Land-based exercise – Hip OA [15]

  • We strongly recommend offering land-based exercise for all people with hip OA to improve pain and function, regardless of their age, structural disease severity, functional status or pain levels. Exercise has also been found to be beneficial for other comorbidities and overall health. However, we are unable to specifically recommend either for or against different types of land-based exercise at this stage. Clinicians should prescribe an individualised progressive exercise

    program, taking into account the person’s preference, capability and the availability of local facilities. Realistic goals should be set. Dosage should be progressed with full consideration given to the frequency, duration and intensity of exercise sessions, number of sessions, and the period over which sessions should occur. The clinician should monitor the person’s response to the exercise program and could try a different form of land-based exercise if improvements are not evident. Attention should be paid to strategies to optimise adherence. Strong for recommendation (when combining all studies of land-based exercise) Conditional (neutral) for recommending one type of land-based exercise over another (eg walking, muscle strengthening, stationary cycling, Tai Chi, Hatha yoga) Moderate (land-based) Very low (walking, muscle strengthening, stationary cycling, Tai Chi, Hatha yoga)

2. Aquatic exercise/ hydrotherapy – Hip OA[15]

  • It may be appropriate to offer aquatic exercise/hydrotherapy for some people with knee and/or hip OA. This will depend upon personal preference and the availability of local facilities.

Manual therapy

Hip Posterior to Anterior Glide

A range of manual therapies is used in the treatment of hip osteoarthritis:[13]

  • Soft tissue techniques and stretches
  • Mobilization of accessory and physiological movements
  • Manipulation

Research is inconclusive on the effect of manual therapy in the treatment of hip osteoarthritis.[4] The immediate effect of a manual therapy, specifically joint mobilization decrease pain and improve hip range of motion, especially in the elderly population. Joint mobilization might reduce pain, might ‘provide a stretching effect on the joint capsules and muscles, thus restoring normal arthrokinematics or may induce pain inhibition and improved motor control’ and might reduce kinesiophobia.[19] 

The RACPG 20188 guidelines Massage and Manual therapy – Hip OA[15]

  • It may be appropriate to offer a short course of massage therapy for some people with hip osteoarthritis (OA). This should be considered only as an adjunctive treatment to enable engagement with active management strategies, and only for short term, cognisant of issues related to cost and access.
  • Manual therapy (stretching, soft tissue and/or joint mobilisation and/ or manipulation) It may be appropriate to offer a short course of manual therapy (stretching, soft tissue and/or joint mobilisation and/ or manipulation) for some people with hip OA. This should be considered only as an adjunctive treatment to enable engagement with active management strategies and only for short term, cognisant of issues related to cost and access.

Outcome Measures[edit | edit source]

The Future[edit | edit source]
