TOTAL HIP REPLACEMENT
TYPES OF HIP REPLACEMENT
- Uncemented Total Hip Replacement: Both the socket and the stem components are fitted into the bone without using acrylic bone cement, and the bone grows into the surface of the components holding them securely. This type of replacement is advised for young patients.
- Cemented Total Hip Replacement: Both the socket and the stem are fixed into the bone using acrylic bone cement, this keeps the implant fixed to the bone.This is advised for elderly patients above the age of 65 years.
- Hip Surface Replacement: Instead of sacrificing the worn out head of femur (ball), only the surface is shaved off and a new surface is fitted onto the socket and the head of femur. This is a bone preserving operation that allows patients faster recovery and patients can have full range of movements allowing them to squat and sit cross legged.
WHAT TO EXPECT FROM HIP REPLACEMENT OPERATION
An important factor in deciding whether to go for total hip replacement operation is understanding what the operation can and can't do. Majority of individuals who undergo hip replacement surgery experience a dramatic reduction of hip pain and a significant improvement in their ability to perform the daily activity. However, hip replacement surgery will not enable you to do more than you could before your hip problem developed. For example if you could not run for 4 KM before your hip problem started, do not expect to do so after your surgery. Following surgery, you will be advised to avoid certain activities for the rest of your life including jogging and high-impact sports.
Even with normal use and activities, an artificial joint (prosthesis) develops minimal wear over time. If you decide to participate in high-impact activities or are over-weight, this wear may accelerate and cause the prosthesis to loosen and become painful. With appropriate activity modification, hip replacement can last several years.
