Hip replacements can wear out over time and require a revision surgery, so activities that may increase stress on the joint are often discouraged. The right level of activity after a hip replacement depends on the person and is best discussed with a doctor.
Pain so long after hip repair should be evaluated and treated. Meanwhile, reduce your exercise.
For mild osteoarthritis, an occasional dose of an over-the-counter pain reliever may be all that’s needed to keep the pain and stiffness associated with osteoarthritis in check. But as osteoarthritis gets worse, men may become interested in ways to cope with pain and other symptoms without taking more medications. The main options are weight control, exercise, and physical therapy, especially for knee and hip arthritis. Some physical therapists offer additional services, such as ultrasound and transcutaneous electrical nerve stimulation (TENS) . Some people with osteoarthritis find acupuncture helpful. The evidence for “joint support” dietary supplements, in contrast, is poor.
The hip is the joint between the upper end of the thighbone (femur) and its socket in the pelvis. When a hip fractures (breaks), the injury is always in the femur. The upper end of the femur can fracture in any one of three places:
The head of the femur — The rounded surface at the very end of the bone that fits into a socket in the pelvis.
The neck of the femur — A somewhat horizontal stretch of bone at the top of the femur that gives this bone the shape of an inverted "L."
Between or below the greater and lesser trochanters — The femur naturally bends at the lower boundary of the hip, angling toward the knee. At this bend, two bony humps protrude along the outside edge of the femur. These ridges are the greater trochanter and lesser trochanter.
Falling is the most common cause of hip fractures. Usually, this occurs in people older than 50. Older people are at risk of hip fractures because of osteoporosis, a disease that weakens bones and may be age-related. A hip also may be fractured during trauma, such as an automobile accident.
Doctors label fractures according to how far the bone has moved from its original position (its displacement). Fractures can be:
Nondisplaced, in which the bone has cracked but not separated
Minimally displaced, in which the bone has shifted slightly along or away from a break
Displaced, in which a part of the bone has become completely detached
In a normal hip joint, the rounded top of the thigh bone (femur) fits into a cup-shaped socket in the pelvis called the acetabulum. This type of joint is called a ball-and-socket joint. When the top of the femur moves out of its normal position in the socket, the hip is said to be disclocated.
Inside a joint, a tissue called cartilage cushions the joint and prevents the bones from rubbing against each other. Osteoarthritis occurs when the cartilage of a joint erodes (breaks down). Bones begin to rub against each other, causing pain and difficulty moving the joint. Osteoarthritis also can affect nearby bones, which can become enlarged in places. These enlargements are called bone spurs or osteophytes.
Although the term arthritis means joint inflammation, there is relatively little inflammation in the joints of most people with osteoarthritis. For this reason, and because this type of arthritis seems to be caused by age-related degeneration of the joints, many experts and health care professionals prefer to call it degenerative joint disease.
Osteoarthritis can range from mild to severe. The pain associated with osteoarthritis can be significant and it usually is made worse by movement. Osteoarthritis can be limited to one joint or start in one joint usually the knee, hip, hand, foot or spine or it can involve a number of joints. If the hand is affected, usually many joints of the fingers become arthritic.
Osteoarthritis probably does not have a single cause, and, for most people, no cause can be identified. Age is a leading risk factor, because osteoarthritis usually occurs as people get older. However, research suggests that joints do not always deteriorate as people age. Other factors seem to contribute to osteoarthritis. Sports-related injuries or repeated small injuries caused by repeated movements on the job may increase the risk of developing osteoarthritis. Genetics also plays a role. Obesity seems to increase the risk of developing osteoarthritis of the knees.
