Introduction

Coxarthrosis, also known as hip osteoarthritis, is a degenerative disease of the hip joint that can lead to significant pain and mobility restrictions. It is one of the most common forms of osteoarthritis and affects millions of people worldwide, particularly older adults. Early detection of symptoms and effective treatment are crucial to improving the quality of life for those affected and slowing the progression of the disease. In this comprehensive blog post, we will examine the symptoms of coxarthrosis in detail, how to recognize them early, and what modern treatment methods are available.

What is Coxarthrosis?

Hip osteoarthritis is a form of osteoarthritis that affects the hip joint. It arises from the progressive breakdown of the articular cartilage, which protects the ends of the bones and enables smooth movement. When the cartilage is broken down, the bones rub directly against each other, causing pain, swelling, and stiffness. The condition can occur unilaterally or bilaterally and has various causes, including genetic predisposition, overweight, injuries, and inflammatory diseases.

Causes of coxarthrosis

The development of coxarthrosis can be influenced by a variety of factors. The most common causes include:

Genetic predisposition

Genetic factors play a significant role in the development of coxarthrosis. A family history of osteoarthritis can increase the risk of developing the condition. Certain genetic markers can increase the susceptibility to cartilage degradation.

Overweight and obesity

Obesity is a significant risk factor for the development of coxarthrosis. Obese individuals exert additional pressure on their hip joints, which accelerates cartilage degradation. Studies show that weight reduction can significantly reduce the risk and symptoms of coxarthrosis.

Injuries and trauma

Injuries to the hip joint, such as fractures or severe bruises, can damage the cartilage and lead to the development of arthrosis. Sports injuries, especially in high-performance athletes, also increase the risk.

Inflammatory diseases

Chronic inflammation, as occurs in rheumatoid arthritis, can break down articular cartilage and lead to osteoarthritis. Inflammatory processes in the body can directly damage cartilage and impair joint health.

Age

With increasing age, the risk of coxarthrosis increases. The articular cartilage is subject to a natural wear process, which is accelerated by aging.

Sex

Women are more frequently affected by coxarthrosis than men, which is attributed to hormonal differences. After menopause, the risk for women increases significantly, which is due to the decline in protective estrogen levels.

Early symptoms of coxarthrosis

Early detection of coxarthrosis is crucial to be able to take appropriate treatment measures in a timely manner. Early symptoms include:

Hip pain

The first signs of coxarthrosis are often hip pain, which initially occurs only under load. The pain can radiate into the groin, thigh or buttocks and improve after rest periods. Initially, these pains are often misinterpreted as muscular complaints.

Stiffness

Another early symptom is stiffness of the hip joint, particularly in the morning or after prolonged periods of inactivity. The stiffness can last from a few minutes to hours and limit mobility.

Movement restrictions

In the early stages of coxarthrosis, patients may experience difficulties performing certain movements, such as putting on shoes or bending. These limitations are often subtle, but can increase over time.

Advanced symptoms of coxarthrosis

In the advanced stage of coxarthrosis, the symptoms worsen and can significantly impair quality of life. The most common advanced symptoms include:

Chronic pain

The pain can become chronic and occur even during rest or at night, which can disrupt sleep. This chronic pain often leads to a significant impairment of daily life and mobility.

Deformity of the hip joint

In advanced stages, visible deformities of the hip joint can occur. These changes can be visible on X-ray and lead to a functional leg length discrepancy.

Gait disorder

The mobility of the hip is severely limited, making walking, climbing stairs, and other everyday activities more difficult. Many patients develop a limp to minimize pain, which can lead to further muscular imbalances and discomfort.

Muscle atrophy

Due to the relieving posture and reduced activity, atrophy of the musculature around the hip joint can occur. This leads to further instability of the joint and intensifies the symptoms.

Secondary complaints

Due to the altered stress and protective posture, secondary complaints such as back pain or pain in other joints can occur. These complaints are often the result of incorrect stress and muscular imbalances.

Diagnosis of coxarthrosis

The diagnosis of coxarthrosis is made through a combination of medical history, physical examination, and imaging techniques. An early and accurate diagnosis is crucial for planning the correct treatment strategy.

Medical history

The doctor will take a detailed medical history to understand the patient's medical history. Important information includes the duration and type of pain, previous injuries, family history, and other medical conditions.

Physical examination

During the physical examination, the doctor will test the mobility of the hip joint and check for tender points. Tests such as the Faber test or the Trendelenburg test can help assess the function of the hip joint.

Imaging Techniques

Imaging techniques such as X-ray, MRI or CT are crucial for the diagnosis of coxarthrosis. X-rays show typical changes such as loss of joint space, osteophyte formation and subchondral sclerosis. An MRI can detail early cartilage damage and soft tissue changes.

Laboratory tests

Labor tests are generally not specific for the diagnosis of hip osteoarthritis, but can help rule out inflammatory diseases. Tests for rheumatoid factors or other markers of inflammatory processes can be performed to consider rheumatic diseases in the differential diagnosis.

Modern treatment methods for coxarthrosis

The treatment of coxarthrosis aims to alleviate pain, improve joint function, and slow the progression of the disease. Treatment may include conservative, invasive, and surgical measures.

Conservative treatment

Conservative treatment is often sufficient in the early stages of coxarthrosis and includes:

Physical Therapy

Physical therapy is one of the most effective measures for treating coxarthrosis. It includes specific exercises to strengthen the muscles around the hip joint, improve mobility, and reduce pain. Therapists can use manual techniques, electrotherapy, and ultrasound to alleviate symptoms.

Medicinal Therapy

Pain medications such as paracetamol and nonsteroidal anti-inflammatory drugs (NSAIDs) can help alleviate pain and inflammation. In severe cases, stronger pain medications such as opioids or injections of corticosteroids into the joint may also be considered.

Weight reduction

Weight reduction is an important aspect of conservative treatment, especially in overweight patients. A reduction in body weight can reduce the pressure on the hip joint and alleviate symptoms.

Orthopedic Assistive Devices

The use of orthopedic aids such as walking sticks or orthopedic shoes can reduce the strain on the hip joint and improve mobility. Special seat cushions and ergonomic furniture can also alleviate symptoms.

Invasive treatment

If conservative measures are not sufficient, more invasive treatments may be considered:

Injection therapy

Injections of corticosteroids or hyaluronic acid into the hip joint can reduce inflammation and improve joint function. These injections are usually effective in the short term and can be repeated.

Minimally invasive surgery

Arthroscopic interventions can be used to clean the joint and remove damaged tissue. These interventions are less invasive than open surgeries and have shorter recovery times.

Surgical Treatment

In advanced coxarthrosis, when conservative and invasive measures are no longer sufficient, surgery may be required:

Total knee arthroplasty (TKA)

The implantation of a total hip replacement is the most common surgical treatment for coxarthrosis. The damaged joint is replaced with an artificial hip. Modern prostheses have a high success rate and can significantly improve quality of life.

Osteotomy

In younger patients or those with specific anatomical problems, an osteotomy may be considered. The bone around the hip joint is realigned to better distribute the load and slow down cartilage degradation.

Hip arthrodesis

In rare cases, when other measures are not successful, hip joint fusion (arthrodesis) may be considered. This permanently stiffens the hip joint to relieve pain.

Prevention of coxarthrosis

The prevention of coxarthrosis includes measures to reduce risk factors and promote joint health:

Healthy nutrition

A balanced diet can help maintain a healthy body weight and support joint health. Foods rich in omega-3 fatty acids, antioxidants, and vitamins can have anti-inflammatory effects and protect cartilage.

Regular Exercise

Regular, joint-friendly exercise is crucial for the prevention of coxarthrosis. Activities such as swimming, cycling, and Nordic walking promote joint health without putting excessive strain on them.

Injury prophylaxis

Avoiding injuries and proper treatment of joint injuries can reduce the risk of developing coxarthrosis. Athletes should pay attention to good technique and adequate training to avoid injuries.

Weight control

Maintaining a healthy body weight is an important preventive factor. Overweight individuals should take measures to reduce weight to reduce the strain on the hip joints.

Rehabilitation after hip surgery

After hip surgery, comprehensive rehabilitation is crucial for the success of the treatment:

Physical therapy

After surgery, rehabilitation begins with intensive physical therapy to improve mobility and strengthen the muscles. An individually tailored exercise program is crucial for restoring function.

Occupational therapy

Occupational therapists help patients resume daily activities and provide support in adapting their home environment. This may include the use of assistive devices and adapting furniture.

Pain management

Effective pain management is crucial for recovery after surgery. This includes the use of pain medications, physical methods, and alternative therapies such as acupuncture.

Psychological support

Psychological support can help to cope with the emotional and psychological challenges after hip surgery. This can be achieved through counseling, self-help groups, and relaxation techniques.

Future perspectives in the treatment of coxarthrosis

The treatment options for coxarthrosis are constantly evolving. Future developments could further improve the quality of life for patients:

Biological Therapies

Research into biological therapies, such as stem cell therapy and genetic approaches, offers promising prospects. These therapies aim to restore cartilage and maintain joint function long-term.

Technological Innovations

Technological advancements, such as the development of new materials for endoprostheses and minimally invasive surgical techniques, could further improve treatment outcomes and reduce recovery times.

Precision Medicine

Precision medicine, tailored to the individual genetic and biological characteristics of the patient, could enable personalized treatment of coxarthrosis in the future.
