Total Hip Replacement (THR)

The hip joint is a ball and socket synovial joint which is made up of the articulation between the pelvic acetabulum and the head of the femur. THR is a surgical procedure where the surgeon removes a damaged section of the hip joint (acetabulum and head of femur) and replaces it with an artificial implant that functions similarly to a normal hip. The implants are made of metal (stainless steel or titanium), or hard plastics. Hip replacement surgery is safe and effective which helps to relieve pain, improve function and return to daily activities. THR is usually an option for people suffering with severe hip pain which interferes with daily activities and when all other non-surgical treatment options do not adequately help to relieve the symptoms.

Why Is It Done?

THR is a common procedure which is done in patients with conditions as below:

OA is a degenerative condition through the aging process, through years of wear and tear, the protective cartilage that covers the ends of bones and joints gets worn out eventually, causing severe hip pain and stiffness.

This is a secondary osteoarthritis condition as a result from an injury or direct trauma. The underlying cartilage and bone become damaged due to improper healing, causing persistent pain and affecting daily activities such as wearing pants or getting up and down from stairs.

Following a fracture or dislocation of the hip joint, the blood supply to the femoral head may be interrupted or reduced. The lack of blood supply may cause the surface of the bone (femoral head) to be brittle and weak to support the hip joint. This condition is also known as osteonecrosis.

Physiotherapy Management

Physiotherapy rehabilitation after THR is considered as the standard and essential treatment. This is because the hip joint is prone to dislocation as a result of the trauma on the hip stabilizers (capsule, ligaments and muscles) and the size of the implant. Activity and exercises are necessary immediately post surgery to regain the use of your joint and muscles around the hip joint. The aim of post-operative rehabilitation is to address the functional needs of the patient (e.g. start mobilizing) and to improve strength and range of motion.
