What Is Total Hip Replacement?
Total hip replacement (THR), also called total hip arthroplasty, is one of the most successful elective surgical procedures in medicine. It involves removing the damaged surfaces of the hip joint and replacing them with high-quality prosthetic components. The result is a pain-free, mobile joint that can last 20 years or more.
Who Needs It?
THR is most commonly performed for severe hip osteoarthritis that has failed conservative management. Other indications include rheumatoid arthritis, avascular necrosis, post-traumatic arthritis, and hip dysplasia. Candidates should have significant pain limiting daily activities, confirmed joint damage on X-ray, and have exhausted non-surgical treatment options.
The Procedure
The operation takes 1–1.5 hours under general or spinal anaesthetic. The worn femoral head and damaged socket are removed and replaced with metal, ceramic, and polyethylene components. Our surgeons use the Direct Anterior Approach, a muscle-sparing technique that avoids cutting through the gluteal muscles, resulting in faster recovery and lower dislocation risk. Robotic assistance (Mako™) is also available for precise implant positioning.
Recovery
Patients are mobilising with a physiotherapist on the day of or day after surgery. Most patients go home after 2–4 days. Crutches or a walking frame are used for 2–6 weeks depending on the approach and recovery. Most patients are walking without aids by 6 weeks and return to recreational activities by 3–6 months.
Risks and Complications
Like all surgery, THR carries risks, which we discuss fully during your consultation. These include: infection (1%), dislocation (0.5–2% with anterior approach), blood clots (DVT/PE), leg length inequality, fracture, nerve injury, and implant loosening (rare in the first 10–15 years). Blood thinners and compression stockings are used routinely to minimise clot risk.
