Informed Consent for Total Hip Arthroplasty (Replacement)

Patient and Orthopedic Team Information

Nature and Purpose of the Procedure

Total hip arthroplasty (replacement) is a surgical procedure performed to relieve severe hip pain and improve joint mobility, typically caused by osteoarthritis, rheumatoid arthritis, avascular necrosis, or hip fracture. Under spinal or general anesthesia, the surgeon makes an incision over the hip joint (using an anterior, lateral, or posterior approach). The damaged femoral head (ball) is removed and replaced with a metal or ceramic stem that is inserted into the femoral canal. A metal or ceramic ball is attached to the stem. The damaged acetabulum (socket) is scraped clean and lined with a metal shell and a plastic or ceramic liner to create a smooth gliding surface. The components may be secured with bone cement or press-fit to allow bone growth into the implant. The procedure typically takes 1 to 2 hours.

Material Risks and Potential Complications

Dislocation: the ball slipping out of the socket, particularly during the first few months when tissues are healing. Dislocation requires manual reduction under sedation or repeat surgery.
Periprosthetic joint infection (PJI), occurring in 1 to 2 percent of cases, which may require long-term antibiotics, surgical washing, or complete removal and replacement of the implants.
Deep vein thrombosis (DVT) or pulmonary embolism (PE) due to blood clots forming in the leg veins; blood thinners and compression devices are used to minimize this risk.
Leg length inequality: a sensation or physical difference in leg length after surgery. While surgeons strive to balance leg lengths, stabilization of the joint may require slight adjustments.
Nerve injury (specifically sciatic or femoral nerve injury) causing weakness, numbness, or foot drop.
Fracture of the femur or acetabulum during bone preparation or implant insertion, which may require wire binding, screws, or bone grafting.
Implant loosening, wear, or osteolysis over time, which may require revision surgery in the future.

Reasonable Alternatives

Non-surgical management: physical therapy, weight loss, assistive devices (cane, walker), and activity modification.
Pharmacological therapy: oral analgesics (acetaminophen, NSAIDs), neuropathic pain agents, or intra-articular steroid injections.
No surgery: accepting current limitations in mobility and pain.

Expected Benefits

The primary expected benefits of total hip replacement include significant reduction or elimination of chronic pain, improved range of motion and joint stability, and restored ability to perform daily activities such as walking, climbing stairs, and sleeping comfortably, thereby improving overall quality of life.

Questions and Understanding Confirmation

I confirm that I have had the opportunity to read this consent form carefully and ask questions of my orthopedic surgeon. All my questions have been answered to my satisfaction. I believe I am making an informed and voluntary decision.
