Osteoarthritis​

The hip is made up of two main parts: the femoral head (ball) and the acetabulum (socket). These bones are covered in a thick layer of cartilage that helps the bones glide smoothly along each other. With arthritis, the cartilage becomes damaged and is gradually worn down. This results in stiffness, pain and discomfort.

 

Symptoms of osteoarthritis include:

• Pain in the affected joint

  • Frequently located in the groin

  • Occasionally located in the buttock or side of hip

  • Worse with activities

  • Improved with rest

• Swelling

• Stiffness

Osteonecrosis​

Osteonecrosis, also called avascular necrosis (AVN), occurs when there is a disruptions in the blood supply to the head of the femur. Because bone needs a constant blood supply to stay healthy, decreased blood flow can lead to necrosis (dead bone) and subsequent collapse of the femoral head. This ultimately can result in the development of osteoarthritis.

Hip Replacement Surgery​

If your surgeon finds that you have significant arthritis or osteonecrosis that is not adequately treated with non-surgical options, a hip replacement may be recommended. A total hip replacement involves replacing the ball and socket with a prosthesis made of metal, ceramic and plastic. This creates a smooth functioning joint surface. Patients can expect that a hip replacement will provide a significant reduction in pain and improvement in function allowing you back to return to the activities you love.​

​

Direct Anterior Approach​

The direct anterior approach is a surgical technique used to access the hip joint through the front of the hip. This means that your surgeon does not need to cut or detach muscle from the pelvis or femur during the operation. This results in a more stable hip, less pain, and a faster recovery. Patients are allowed to bend and walk on their new hip immediately after surgery.

 

Some patients are also candidates for the “bikini incision”. This is a direct anterior approach in which a small incision is made in the natural crease lines so that it can easily be concealed.
