Os, articulations et muscles

Arthritis is a term used to describe inflammation or swelling of one or more joints. It commonly causes joint pain, stiffness, and reduced mobility. There are over 100 different types, but the most common are osteoarthritis (joint wear) and rheumatoid arthritis (immune system attack).

Bone disorders are conditions that weaken, deform, or otherwise alter bone tissue, making bones fragile and prone to fractures. They range from common age-related loss of bone mass (osteoporosis) to genetic conditions, infections, and cancers.

A fracture is a medical term for a broken or cracked bone. It occurs when a physical force or medical condition exceeds the bone's breaking point. While bones are naturally rigid, extreme trauma or long-term stress can cause them to break partially or completely.

Knee pain is typically caused by acute injuries (like ligament tears or meniscus damage), repetitive overuse (such as tendonitis or runner's knee), or degenerative conditions like osteoarthritis.

Muscle issues range from minor strains and cramps to chronic conditions and neuromuscular disorders. Common causes include overuse, injury, vitamin deficiencies, or autoimmune diseases.

Sports injuries are generally caused by overuse, direct impacts, or poor technique. They occur when physical exertion places a demand on muscles, joints, or bones that exceeds their structural limits.
