Osteoarthritis (Osteo-Arthrosis, Degenerative Joint Disease)
This disease of joints is not usually inflammatory but is characterized by wear and tear of the joints and is generally age related. It is the commonest type of arthritis. Joints which are particularly prone to develop osteoarthritis are the hip, knee, hands and spine. Past or continuing trauma (ie injury) to the joints can accelerate the onset of osteoarthritis
In the great majority of persons with osteoarthritis the disease is mild (with minimal or no needs) and principally affects one particular joint, which is the main source of pain and discomfort, such as the knee or hip, with minor or no involvement of other joints. The condition may have come to light during x-ray examination, even before the symptoms were noticed. In other people, however, the disease is more severe, causing deformity and extreme pain in affected joints. The problems may be alleviated by surgery, to replace the diseased joint with an artificial one (prosthesis). Those most commonly replaced in this way are the hip and knee joints. This operation is most often successful in significantly relieving joint pain and restoring pain-free movement.
In older people multiple joints are affected and, because of disuse of the joints due to pain, there may be muscle wasting. This can be a factor contributing to falls in the elderly.
Care Needs
(i) In osteoarthritis, the need for help and its frequency, will depend very much on the number and location of joints involved and the degree of deformity, which may be so severe that surgical intervention is necessary to correct it and to relieve pain.
(ii) Loss or limitation of hand and arm function may lead to a need for help during the day. In the early stages of the condition manual dexterity may be impaired leading to difficulty in handling common utensils. It may also make simple household tasks difficult or dangerous depending upon the degree of loss of function and reduced manual dexterity, and, of course, whether one or both hands/arms are involved.
(iii) When hip and/or knee function is limited or restricted with reduction in the ranges of movement at these joints, there may be problems with bathing, dressing and undressing the lower half of the body, going up and down stairs and rising from a chair and in walking. In the older person, help may be needed getting out of bed in the morning and back in at night.
(iv) Even when suitable, readily available, equipment or technical aids resolve some difficulties, others may persist and will depend upon individual circumstances.
Mobility Considerations
(i) Loss of hip and/or knee functions, especially when these are associated with problems in the ankles and feet, may lead to substantial difficulties in walking and being able to get around both in the home and outdoors. When the knee is affected the joint may become unstable, increasing the risk of falls, particularly in elderly people.
(ii) In people with long-standing and advanced osteoarthritis of weight-bearing joints (such as the hip, knee, ankles and feet, etc) treatment with painrelieving drugs (analgesics) or anti-inflammatory medications and physiotherapy, etc, may not significantly improve walking. Where joints have been replaced, however, walking itself and pain associated with walking is usually very much improved.
Duration of Needs
In people with the much more common milder forms of osteoarthritis care needs are minimal and walking is not usually limited to a significant extent. However, even in people with the milder forms of osteoarthritis affecting the weight-bearing joints there may be short periods lasting several weeks when there is increased pain and stiffness which may affect care needs and walking. The duration of established care needs and walking difficulties may be reduced, or even eliminated, by successful replacement with prosthetic joints.
