Total Hip Replacement Surgery Overview What is Total Hip Replacement? Total Hip Replacement (THR), also called Total Hip Arthroplasty, is a surgical procedure in which a damaged or worn-out hip joint is replaced with an artificial implant. It is typically recommended when hip pain and stiffness interfere with daily activities and conservative treatments (like medication or physical therapy) no longer provide relief. Indications for Surgery Osteoarthritis of the hip (most common) Rheumatoid arthritis Post-traumatic arthritis Avascular necrosis Hip fractures Failed previous hip surgeries Parts of the Hip Joint Replaced Femoral head – replaced with a metal or ceramic ball Acetabulum (hip socket) – lined with a metal shell and plastic, ceramic, or metal insert Stem – inserted into the femur for support Types of Hip Implants Cemented prosthesis – fixed with bone cement; often used in older patients Cementless prosthesis – relies on bone growth to secure; more common in younger, active patients Hybrid – a combination of cemented and cementless components Surgical Procedure Performed under general or spinal anesthesia Incision made over the hip Damaged bone and cartilage removed Artificial joint implanted Surgery typically takes 1–2 hours Recovery and Rehabilitation Hospital Stay: 2–4 days Weight Bearing: Often allowed within a day, depending on the implant type Physiotherapy: Starts immediately after surgery to restore motion and strength Full Recovery: Usually within 3–6 months Benefits Pain relief Improved mobility Better quality of life Long-lasting results (implants may last 15–20+ years) Risks and Complications Infection Blood clots Dislocation of the hip Leg length discrepancy Implant loosening or wear over time Nerve or blood vessel injury Post-Surgery Tips Follow rehab protocols strictly Avoid high-impact activities Use assistive devices if advised (walker, crutches) Maintain a healthy weight to reduce stress on the joint
