# Physiopathologie osseuse: définitions, symptômes et traitements ## Arthrose et Arthrite **Image:** A mind map with the words “Arthrose et Arthrite” in the centre. The map has a large, human skeleton in the centre as a reference point for the other sections. ### **Definition of Osteoarthritis** - Osteoarthritis is a degenerative joint disease characterized by cartilage wear. - This condition leads to pain and stiffness, often linked to age and repetitive activities. **Image:** Diagram depicting the anatomy of a healthy knee (labeled “Normal”) compared to a knee with osteoarthritis (labeled “Arthrose”) ### **Definition of Arthritis** - Arthritis is an inflammation of the joints, which can cause pain, swelling and reduced mobility. - It can be triggered by auto-immune, infectious, or metabolic factors. **Image:** Diagram comparing the anatomy of a healthy knee joint (labeled “ARTICULATION NORMALE”) to an arthritic knee joint (labeled “ARTHRITE”). ## **Importance of understanding these diseases** - Understanding osteoarthritis and arthritis is critical for patients and health professionals. - A good understanding of the pathology helps to develop treatment strategies, reduce pain, and improve the quality of life for the affected patients. ## **Causes of Osteoarthritis** - Osteoarthritis is influenced by several factors such as genetics, age and obesity. - It is essential to understand these causes for anticipating and managing the disease. ### **Genetic factors** - Family history increases the risk of osteoarthritis. - Specific genes can predispose individuals to joint problems such as cartilage degeneration. **Image:** Image showing a series of human skeletons developing from a more primitive ape-like skeleton to a more advanced human one. ### **Age and wear** - Aging is the main factor in the development of osteoarthritis. - Joints undergo progressive wear, leading to decreased cartilage elasticity with age. **Image:** Several identical human figures of increasing size and age. ### **Obesity and weight** - Being overweight puts increased pressure on the joints, especially the knees and hips. - Weight loss can reduce the risk of osteoarthritis and alleviate symptoms. **Image:** A person looking thin with a small shadow, and to their side, the same individual who looks much heavier, with a large projected shadow. ## Causes of Arthritis - Arthritis is often caused by a combination of immune, infectious, and environmental factors which interact together to cause joint inflammation. - It is crucial to fully understand the causes of this disease for diagnosing and treating it properly. ### **Environmental factors** - Environmental factors, such as joint injuries, can also contribute to arthritis. - These factors in connection with genetic predispositions increase the risk of developing arthritis. **Image:** Two men lifting a heavy box. One is positioned correctly with a straight back and bent knees - the other has a bent back and straight knees - indicating incorrect form. ### **Immune reactions** - Immune reactions play a key role in arthritis. - The immune system erroneously attacks joint tissues, leading to inflammation and pain. - Auto-immune diseases such as rheumatoid arthritis can illustrate this alteration. **Image:** an image of the human body showing organs and the immune system in the background. ### **Infections** - Certain infections can trigger arthritis, for example, tick-borne Lyme disease. - Lyme disease causes infectious arthritis, resulting in severe symptoms that require urgent medical treatment. ## **Symptoms of Osteoarthritis** - Osteoarthritis presents itself through many symptoms, though the most prevalent are joint pain and stiffness. - **Image:** A human skeleton drawn with a highlighted area of each joint. ### **Joint pain** - Joint pain is the main symptom linked to Osteoarthritis. - It worsens with movement and is relieved by rest, primarily affecting the weight-bearing areas of the body: the knees, hips, and spine. **Image:** An image of a human body with highlighted areas of possible pain. ### **Joint deformation** - Over time, osteoarthritis can lead to joint deformation, visible through bumps or nodules. - Affected joints may become less flexible, making everyday activities difficult. **Image:** A close up of a hand showing different joints in an arthritic state. ## **Symptoms of Arthritis** - Symptoms of arthritis can vary from person to person, but often include noticeable inflammation, chronic fatigue, and general discomfort, all of which affect the quality of life. ### **Joint inflammation** - Joint inflammation is a major symptom of arthritis. - It manifests as redness, swelling, and heat in the affected joints, making movement painful and limited. **Image:** A human skeleton diagram with highlighted areas of possible pain, and text that mentions "OSTEÓARTHRITE". ### **Fatigue, fever, and malaise** - Fatigue is a common symptom, linked to the body fighting inflammation, affecting energy levels and motivation for daily activities. - Fever and general malaise can occur during episodes of arthritis and require appropriate medical attention. **Image:** A woman sitting at a desk with her head in her hands, looking fatigued. ## **Treatments** - Different treatments exist to manage osteoarthritis and arthritis, including non-medicinal and medicinal approaches tailored to each condition. ### **Treatment for Osteoarthritis** - **Non-medicinal treatments:** - Analgesics and anti-inflammatories: reduce pain and inflammation. - Physiotherapy, adapted exercises, and acupuncture: aim to relieve pain and improve joint function. - **Medicinal treatments:** - Hormone therapy - Surgery - Anti-inflammatory medications - Joint support (bandages, braces) - Computer-assisted tomography ### **Medications for Arthritis** - Specific medications such as anti-inflammatories, antirheumatics, and biologics are used for arthritis. - These treatments aim to control the progression of the disease and improve the quality of life for patients. ## **Prevention and management of osteoarthritis and arthritis** - Adopting a healthy lifestyle can significantly reduce the risk of osteoarthritis and arthritis while improving the quality of life for patients. - **Regular exercise** - Regular physical exercise that is appropriate to the individual can strengthen surrounding muscles, improve flexibility and reduce pain. - Activities such as swimming, walking, and yoga are particularly beneficial for people suffering from osteoarthritis and arthritis. **Image:** A series of people undertaking different types of physical exercise including cycling, yoga, running, weight training. - **Balanced diet** - A diet rich in omega-3 fatty acids, fruits and vegetables, can reduce inflammation and improve joint health. - Reducing the consumption of processed foods and refined sugars also helps to control symptoms linked to osteoarthritis and arthritis. **Image:** A plate showing balanced food on it, with salad and some fried food. - **Regular medical follow-up** - Regular medical follow-up is critical to monitor the evolution of joint diseases and adjust treatments accordingly. - Frequent consultations provide an opportunity to discuss new treatment options and receive advice tailored to each individual. **Image:** Two doctors standing side by side, arms crossed. **Image:** A mind map with the words “DES QUESTIONS?” ("Any questions?" ) written in the centre. The map has several boxes for each section from the original mind map but with less detail. Each box has a question mark in the top right hand corner.
