The term ‘arthrosis’ (joint wear) refers to one of the most common diseases of the postural and musculoskeletal system. When a joint wears out, its protective layer, the cartilage and sometimes the underlying bone are damaged. The disease affects mainly the hands, shoulder, knee or hip joint.


Structure of the joints

Joints generally consist of a joint head and socket with a layer of cartilage in between. The joint capsule surrounding the joint forms its protective outer shell together with muscles, ligaments and tendons. The articular cartilage covering the ends of the bones can both compensate for unevenness of the joint surfaces and absorb shocks thanks to its plasticity. Constant alternation of strain and relief ensures even nourishment and maintenance of the articular cartilage.

Osteoarthritis: Pain that starts after a period of rest

Are you familiar with the so-called "start-up pain" and joint stiffness in the morning? The knee pain slowly subsides only after some time. Pain usually sets in when bending over, straining – for example when climbing stairs – and sometimes also after sitting or lying down for a long time. These signs may indicate the onset of knee joint osteoarthritis. What can you do? How can you prevent it?

What is a hallux rigidus?

Hallux rigidus: arthrosis in the metatarsophalangeal joint

Hallux means ‘big toe’. Joint wear – i.e. arthrosis – in the metatarsophalangeal joint of the big toe is referred to as hallux rigidus, or ‘stiff big toe’. Hallux rigidus is often painful, since the cartilage in the joint is being ground down with every movement. Over the long term the joint may stiffen. Find out how to recognise hallux rigidus and learn what you can do to relieve the pain and prevent secondary afflictions.
