What is hip osteoarthritis (coxarthrosis) and how does it develop?
Hip osteoarthritis, or coxarthrosis, is a chronic degenerative disease of the hip joint in which the protective joint cartilage is gradually broken down. As one of the largest ball-and-socket joints in the human body, the hip joint connects the head of the femur with the acetabulum of the pelvis and carries our entire body weight with almost every movement. In a healthy state, a smooth, elastic layer of cartilage covers the joint surfaces of the femoral head and the socket. This protective layer acts as a perfect shock absorber, cushions loads and allows the joint partners to move against each other without friction.
In osteoarthritis, the cartilage progressively loses its elasticity and thickness. The originally smooth surface becomes rougher, cracks appear and eventually areas of exposed bone develop. When the bones rub directly against each other, the characteristic pain and restricted movement arise. At the same time the body responds with inflammatory reactions, which place additional strain on the joint and produce the typical sensation of pain.
An important distinction: a difference is made between primary coxarthrosis, where no clear cause can be identified and which often occurs as age-related wear, and secondary coxarthrosis, which develops as a consequence of pre-existing conditions, malalignment or injury. This distinction is decisive for choosing the optimal treatment strategy, because different therapeutic approaches follow from it.
The statistical significance in Germany is considerable: around 2.5 million people are affected by hip osteoarthritis, with women falling ill more often than men, particularly after the menopause. The risk rises markedly from the age of 50, and more than 200,000 hip prostheses are implanted every year. These figures make clear that this is a genuinely widespread disease affecting many families.
Causes of hip osteoarthritis – from malalignment to circulatory disorders
The development of hip osteoarthritis can rarely be traced back to a single cause – it is usually a complex interplay of various factors. In secondary coxarthrosis, which accounts for around 80 percent of cases, specific triggers can be identified. Recognising these causes early is decisive for influencing the course of the disease positively and developing targeted treatment strategies.
Congenital or acquired malalignment plays a central role: hip dysplasia, an insufficiently developed acetabulum, leads to localised overloading of the cartilage and therefore to accelerated wear. Hip impingement – a mechanical blockage between the femoral head and the socket – causes recurring microtrauma to the cartilage and the labrum. These mechanical problems result in uneven pressure distribution within the joint.
Excess weight is one of the most important modifiable risk factors. Every additional kilogram of body weight increases the mechanical load on the hip joints many times over. Fatty tissue also produces pro-inflammatory messenger substances that can further damage the cartilage. Circulatory disorders of the femoral head (avascular necrosis) cause bone tissue to die off, which can make the cartilage above it collapse.
Inflammatory joint diseases such as rheumatoid arthritis can trigger chronic inflammation that attacks the joint cartilage directly. The consequences of injury after accidents such as a femoral neck fracture or damage to the labrum can permanently disturb joint mechanics and lead to post-traumatic osteoarthritis years later. Genetic predisposition also plays a role – clusters within families point to hereditary components that can affect cartilage quality or the shape of the joint.
Recognising symptoms – when should you act?
The first signs of hip osteoarthritis usually develop gradually and are often dismissed as normal signs of ageing. This insidious onset means that many of those affected seek professional help only late. Start-up pain after sitting for a long time or when getting up in the morning is a typical early warning sign that should be taken seriously. The hip feels stiff, as though it had “rusted up”, and needs a few steps or movements before it becomes supple again. At this stage the symptoms still improve with movement, which tempts many people to ignore them.
As the condition progresses, characteristic groin pain appears, which can typically radiate into the thigh or even as far as the knee joint. Many patients therefore first consult a doctor about knee complaints without suspecting that the cause lies in the hip. This radiating pain is a typical phenomenon in hip problems and can make diagnosis more difficult. Mobility decreases step by step – putting on shoes and socks becomes a challenge, climbing stairs takes increasing effort, and everyday activities such as getting out of the car become painful.
In advanced stages, night pain and pain at rest develop, which can considerably disturb sleep. The pain becomes a constant companion that severely restricts quality of life. Those affected often develop a characteristic protective posture with a typical limp, which in turn can cause tension in the back and lumbar spine. These compensation mechanisms frequently lead to additional complaints throughout the musculoskeletal system.
An important checklist for those affected:
- Morning stiffness of the hip after getting up
- Pain in the groin and thigh, particularly under load
- Restricted mobility when bending down or getting dressed
- Difficulty climbing stairs or walking longer distances
- Night pain when lying on the affected side
- Grinding or cracking sounds during movement
- An increasingly shorter walking distance because of pain
Stages of hip osteoarthritis – from the first signs to the final stage
Medically, hip osteoarthritis is divided into four degrees of severity that reflect both the extent of cartilage damage and the effects on quality of life. This classification helps orthopaedic specialists assess the degree of joint wear objectively and plan a suitable, stage-appropriate therapy. Early detection in the initial stages is decisive, because this is where joint-preserving measures promise the greatest success.
Stage I (initial stage): the joint cartilage shows the first superficial roughening or slight softening. An X-ray often reveals only minimal change or none at all, and the joint space still appears normal. At this stage patients are usually completely free of symptoms, which is why the diagnosis is often made by chance during routine examinations. This is where the best opportunities for preventive measures lie.
Stage II (early stage): the cartilage damage becomes deeper and more extensive, and the joint space begins to narrow slightly. The first small bony outgrowths (osteophytes) may form at the edges of the joint – the body’s reaction to the altered load. The typical start-up and load-related pain appears, although it can still be eased by movement. At this stage conservative treatment is particularly promising.
Stage III (advanced stage): more than 50 percent of the cartilage has already been worn away and the joint space is clearly narrowed. The osteophytes grow larger and can restrict mobility further. Pain occurs more often and more intensely, frequently under light load or even at rest. Quality of life is noticeably impaired and everyday activities become increasingly difficult.
Stage IV (final stage): the joint cartilage is largely or completely destroyed – doctors speak of a “bald patch” in the cartilage. The bones of the femoral head and the socket rub directly against each other, which causes severe, persistent pain. The restriction of movement is massive and the joint often becomes partially stiff. At this stage surgical joint replacement is usually the only route back to pain-free mobility.
Conservative treatment before surgery
Conservative therapy forms the foundation of every successful hip osteoarthritis treatment and should as a rule be exhausted before any surgery. The main aim is to relieve pain, improve joint function, slow the progression of the osteoarthritis and preserve the patient’s quality of life for as long as possible. The therapy is designed to be multimodal and is tailored individually to the particular stage of the osteoarthritis as well as to the patient’s personal needs and circumstances.
Physiotherapy is at the absolute heart of the treatment. An experienced physiotherapist develops individual training programmes comprising targeted exercises to strengthen the muscles surrounding the hip together with stretching exercises to maintain and improve mobility. These programmes are continuously adapted to the progress of the therapy and can be carried out both in the practice and at home.
Weight reduction plays a central role in the treatment concept, since losing just five kilograms can reduce the risk of osteoarthritis by almost 50 percent. Every superfluous kilogram places additional strain on the hip joints and accelerates cartilage breakdown. A balanced, anti-inflammatory diet with plenty of vegetables, omega-3 fatty acids and little red meat supports the healing process further.
Drug-based pain therapy uses modern, stomach-friendly anti-inflammatory medication (NSAIDs), which not only relieves pain but also reduces inflammatory processes in the joint. Hyaluronic acid injections can improve joint lubrication in early to intermediate stages and promote cartilage metabolism. Physical therapies such as targeted heat and cold applications, together with orthopaedic aids such as walking sticks or cushioning shoe insoles, round out the comprehensive range of treatment.
Evidence-based success rates: scientific studies show impressively that conservative treatment approaches can bring a marked improvement in symptoms for 60 to 70 percent of patients, particularly when they are used early and consistently. These figures underline the importance of timely, systematic non-surgical treatment.
Movement as medicine – how exercise helps with hip osteoarthritis
Contrary to a widely held assumption, physical activity is not harmful in hip osteoarthritis but demonstrably beneficial and therapeutically valuable. For a long time the advice was to rest painful joints – today we know the opposite is true. Regular, appropriate physical activity stimulates cartilage metabolism and supplies the tissue with important nutrients. Joint cartilage has no blood supply of its own; it is nourished passively by the synovial fluid. The process works like a sponge: under load the cartilage is compressed and releases waste products, and when the load is removed it soaks up nutrient-rich fluid again.
Joint-friendly sports are particularly recommended because they relieve the joints while strengthening the muscles at the same time. Swimming and aqua aerobics are ideal, since the buoyancy of the water relieves the joints almost completely while the water’s resistance strengthens the muscles effectively. Cycling offers cyclical movement without impact loading and is ideal for mobilising the hip joint. Nordic walking uses the support of poles, so that part of the body weight is absorbed and the hip joints are relieved.
Strength training to build up the hip, thigh and trunk muscles stabilises the joint and can demonstrably reduce pain. Strong muscles act like an active corset that stabilises the joint, cushions impact and relieves the joint surfaces. The right dosage matters: two to three training sessions of 45 minutes per week are optimal for most patients.
Activities to avoid: high-impact sports such as jogging on hard surfaces, contact sports with jerky movements, or activities involving sudden stops and abrupt changes of direction should be avoided, as they can place additional strain on the cartilage.
Modern surgical treatment options
When conservative measures are no longer sufficient and quality of life is considerably restricted, modern surgical procedures offer effective and safe solutions. The decision in favour of an operation is never taken lightly; it follows a careful weighing of all the factors and is always made in close consultation with the patient. Orthopaedics today offers a differentiated range of procedures that are matched individually to the stage of the osteoarthritis, the patient’s age and the underlying causes.
Hip arthroscopy, minimally invasive “keyhole surgery”, makes it possible to treat the causes specifically in early stages of osteoarthritis. Fine instruments and a high-resolution camera are introduced through skin incisions only a few millimetres long in order to smooth cartilage damage, remove loose bodies, suture a torn labrum or correct malalignment. This technique is particularly gentle on tissue and allows rapid rehabilitation.
Cartilage transplantation and regenerative procedures offer new hope for younger patients with limited but deep cartilage defects. The patient’s own cartilage cells are multiplied in a laboratory and then introduced into the damaged areas in order to form new, healthy cartilage tissue. Corrective osteotomy corrects pronounced malalignment through targeted repositioning of the bone and can slow the course of the disease considerably by relieving damaged areas of cartilage.
In advanced osteoarthritis, minimally invasive joint replacement is used. Modern surgical techniques allow small skin incisions, spare the muscles and lead to markedly faster mobilisation. Patients can often get up again on the day of the operation and put full weight on the joint. Complication rates have fallen significantly today, and the service life of the implants has improved considerably thanks to better materials and surgical techniques.
Our orthopaedic center in Munich attaches great importance to individual advice: the choice of surgical procedure must be made strictly on an individual basis. Age, level of activity, concomitant illnesses and the patient’s personal wishes all feed into the decision. Our aim is to offer every patient the best possible solution tailored to them.
Joint replacement – when does an artificial hip joint make sense?
The decision in favour of an artificial hip joint follows clear criteria in line with medical guidelines and should never be taken prematurely. Hip replacement is recommended when conservative treatment over at least three to six months has brought no adequate relief, when at least the third stage of osteoarthritis is present and when quality of life is considerably impaired. What is decisive is not the X-ray alone, but above all the patient’s subjective level of suffering.
Various types of prosthesis are available and are selected according to the individual situation. The total hip replacement replaces the femoral head and the socket completely and is the standard in pronounced osteoarthritis. Short-stem prostheses are a bone-preserving alternative for younger patients with good bone quality and keep options open for any later revision surgery. Resurfacing caps only the femoral head where bone substance is still good and is likewise very bone-preserving.
The choice of material for the implants is made individually: modern implants – usually combinations of titanium, ceramic or special, highly cross-linked plastics – are biocompatible and low-wear. The various bearing combinations (for example ceramic-on-ceramic or ceramic-on-polyethylene) are selected according to the patient’s age, activity level and bone quality and have a decisive influence on the longevity of the prosthesis.
Modern service life: today’s implants achieve impressive service lives of 15 to 20 years and more. Rehabilitation begins on the first day after the operation with physiotherapeutic support, and most patients can leave hospital again after a few days.
Important aftercare advice: regular check-ups with the orthopaedic specialist, lifelong endocarditis prophylaxis during dental procedures and the avoidance of extreme loads secure the long-term success of the joint replacement. Structured rehabilitation is decisive for success and for restoring full mobility.
Frequently asked questions (FAQ)
What can I do about hip osteoarthritis myself?
Your own initiative plays a decisive and often underestimated role in the treatment of hip osteoarthritis. You can influence the course of your condition actively and substantially. Regular exercise is absolutely essential – joint-friendly sports such as swimming, cycling or Nordic walking keep the joints mobile, strengthen the stabilising muscles and promote cartilage metabolism. Weight reduction relieves the hip joints considerably; even five kilograms less can bring noticeable improvement.
An anti-inflammatory diet with plenty of vegetables, omega-3 fatty acids from fish or linseed oil and little red meat supports the healing process naturally. Heat applications such as warm baths or heat patches, as well as physical therapies, can relieve pain and promote circulation. Adapting everyday activities also matters: avoid deep squatting, use walking aids where necessary and wear cushioning shoes with good soles.
Is it possible to treat hip osteoarthritis without surgery?
Yes, in many cases hip osteoarthritis can be treated successfully without surgery, particularly in early to intermediate stages. Conservative therapies such as systematic physiotherapy, adapted medication and consistent lifestyle changes can slow the course of the disease markedly and reduce symptoms considerably. Hyaluronic acid injections improve joint lubrication, while targeted exercises strengthen the muscles and stabilise the joint.
Scientific studies show impressively that 60 to 70 percent of patients experience noticeable and lasting improvement through consistently applied conservative measures. The decisive factor for success is starting therapy early, before irreversible joint damage occurs. The sooner you act, the better your chances of preserving the natural joint and avoiding surgery, or at least postponing it considerably.
When is the right time for an artificial hip joint?
The optimal time for joint replacement varies greatly from person to person and does not depend on the X-ray findings alone. The decisive factors are above all your personal level of suffering, the restriction of your quality of life and the failure of conservative therapies over a reasonable period. Ask yourself the following questions: does the pain severely affect your everyday life? Can you no longer sleep through the night because of it? Do you have to give up activities that matter to you?
Modern surgical techniques and improved implants now allow younger patients too to undergo successful joint replacement with excellent long-term results. It is important to carry out the procedure neither too early nor too late – enduring pain for too long can lead to muscle weakness, restricted movement and compensation mechanisms that make later rehabilitation more difficult. At our center in Munich we are happy to advise you in detail on the optimal time for your individual situation.
