Arthrosis is a degenerative joint problem that initially affects the articular cartilage, which deteriorates and destroys but ends up affecting all the structures of the joint: bone, synovial membrane… The ensuing chronic joint inflammation mainly causes pain and stiffness. Today, it is the most common joint pathology in Spain. 50% of people over 50 suffer from it, particularly in the spine, knees and hips. If you are over 50 years old, if you are obese, if you practice sports intensely on a regular basis, if you have a job involving repetitive movements or postures (hairdresser, mason, ironer…): You have a higher risk of suffering from osteoarthritis! Because osteoarthritis is not just a problem “of the elderly”. Increasingly, there are younger people who show signs of osteoarthritis.
