Like other joints that carry your weight, your hips may be at risk for "wear and tear" arthritis. Osteoarthritis is the most common form of the disease. The smooth articular cartilage (cushion) that helps your hip joint glide may wear thin. Your first sign may be some discomfort and stiffness in your groin, buttock or thigh when you wake up in the morning. The pain flares when you're active and gets better when you rest.
Avascular necrosis, also called osteonecrosis is a condition in which bone death occurs because of inadequate blood supply to it. Lack of blood flow may occur when there is a fracture in the bone or a joint dislocation that may damage nearby blood vessels.
Developmental dysplasia of the hip (DDH) or Hip dysplasia is a condition which is seen in infants and young children as a result of developmental problems in the hip joint. The femur (thigh bone) partially or completely slips out of the hip socket causing dislocation at the hip joint. It is most common in first born babies with a family history of the disorder. The exact cause for hip dysplasia is not known. Genetic factors play an important role in causing this birth defect.
Like other joints that carry your weight, your knees are at risk for "wear and tear" arthritis. The smooth articular cartilage (cushion) that helps your knee joint glide may wear thin. Generally, the pain of arthritis develops gradually, although sudden onset is also possible. The knee may become stiff and swollen, making it difficult to move.
Osteonecrosis is a condition in which death of a section of bone occurs because of lack of blood supply to it. It is one of the most common causes of knee pain in older women. Women over the age of 60 years of age are commonly affected, three times more often than men.
Meniscal tear is the commonest knee injury in athletes, especially those involved in contact sports. A sudden bend or twist in your knee can cause the meniscus to tear. This is a traumatic meniscal tear. Elderly people are more prone to degenerative meniscal tears as the cartilage wears out and weakens with age. The two wedge-shape cartilage pieces’ present between the thighbone and the shinbone are called meniscus. They stabilize the knee joint and act as “shock absorbers”.
Failed Hip and Knee Replacements
Conventional, primary total hip replacement is a durable operation in the majority of patients. A hip replacement is a mechanical device with parts, most commonly referred to as a “ball and socket,” that are assembled before and during the operation. After surgery, this ball-and-socket prosthesis restores movement in the hip throughout the life-span of the prosthesis.
