A total hip replacement is a surgical procedure whereby the diseased cartilage and bone of the hip joint is surgically replaced to relieve the patient of hip is discomfort. If the hip has been damaged by arthritis, a fracture, or because of heavy impact; performing regular activities may become painful and difficult. One will find stiffness in the hip, and discomfort while walking, or bending and perhaps even while resting. Hip replacement surgery is commonly advised when:

• Hip pain that limits everyday activities and impairs overall quality of life, such as walking or bending
• Hip pain that continues while resting, either day or night
• Stiffness in a hip that limits the ability to move or lift the leg
• Inadequate pain relief from anti-inflammatory drugs, physical therapy, or walking supports

Total hip replacements are performed most commonly because of:

• Progressively worsening of severe arthritis in the hip joint. The most common type of arthritis leading to total hip replacement is osteoarthritis of the hip joint. The most common cause of chronic hip pain and disability is arthritis. Osteoarthritis, rheumatoid arthritis, and traumatic arthritis are the most common forms of this disease
• Avascular necrosis (Osteonecrosis)
• Childhood hip disease

In Hip Replacement Surgery, the surgeon removes the damaged sections of your hip joint and replaces them with parts usually constructed of metal, ceramic and very hard plastic. This artificial joint or prosthesis helps reduce pain and improve function. The prosthetic components could either be ‘press fit’ into the bone or they may be cemented into place. Based on a number of factors, such as the quality and strength of your bone, the orthopedic surgeon will decide to press fit or to cement the components or use a combination of both.
