Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant, that is, a hip prosthesis. Hip replacement surgery can be performed as a total replacement or a hemi/semi(half) replacement. Such joint replacement orthopaedic surgery is generally conducted to relieve arthritis pain or in some hip fractures. A total hip replacement consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head. Hip replacement is one of the most common orthopaedic operations, though patient satisfaction varies widely between different techniques and implants. Approximately 58% of total hip replacements are estimated to last 25 years. The average cost of a total hip replacement in 2012 was $40,364 in the United States, and about $7,700 to $12,000 in most European countries.
Avascular necrosis (AVN), also called osteonecrosis or bone infarction, is death of bone tissue due to interruption of the blood supply. Early on, there may be no symptoms. Gradually joint pain may develop, which may limit the person's ability to move. Complications may include collapse of the bone or nearby joint surface.
Knee replacement, also known as knee arthroplasty, is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve pain and disability, most commonly offered when joint pain is not diminished by conservative sources. It may also be performed for other knee diseases, such as rheumatoid arthritis. In patients with severe deformity from advanced rheumatoid arthritis, trauma, or long-standing osteoarthritis, the surgery may be more complicated and carry higher risk. Osteoporosis does not typically cause knee pain, deformity, or inflammation, and is not a reason to perform knee replacement.
Hip resurfacing has been developed as a surgical alternative to total hip replacement (THR). The procedure consists of placing a cap, which is hollow and shaped like a mushroom, over the head of the femur while a matching metal cup is placed in the acetabulum, replacing the articulating surfaces of the person's hip joint and removing very little bone compared to a THR. When the person moves the hip, the movement of the joint induces synovial fluid to flow between the hard metal bearing surfaces lubricating them when the components are placed in the correct position. The surgeon's level of experience with hip resurfacing is most important; therefore, the selection of the right surgeon is crucial for a successful outcome. Health-related quality of life measures are markedly improved and the person's satisfaction is favorable after hip resurfacing arthroplasty.
Minimally invasive hip resurfacing (MIS) is a total or partial hip surgery that can be carried out through an incision of less than 10 cm without imparting great forces on the anatomy or compromising component positioning.

Sean Patrick Francis Hughes is emeritus professor of orthopaedic surgery at Imperial College London where he was previously professor of orthopaedic surgery and head of the department of surgery, anaesthetics and intensive care. Earlier in his career he had been professor of orthopaedic surgery at the University of Edinburgh.
"Professor" Derek McMinn is a British orthopaedic surgeon and inventor who practised in Birmingham, United Kingdom at the BMI Edgbaston Hospital until his suspension in 2020. McMinn is currently under police investigation for allegedly keeping the body parts of thousands of patients over a 25-year period.
Hip arthroscopy refers to the viewing of the interior of the acetabulofemoral (hip) joint through an arthroscope and the treatment of hip pathology through a minimally invasive approach. This technique is sometimes used to help in the treatment of various joint disorders and has gained popularity because of the small incisions used and shorter recovery times when compared with conventional surgical techniques. Hip arthroscopy was not feasible until recently, new technology in both the tools used and the ability to distract the hip joint has led to a recent surge in the ability to do hip arthroscopy and the popularity of it.
John H. Healey is an American cancer surgeon, researcher, and expert in the surgical treatment of benign and malignant bone tumors and other musculoskeletal cancers. He serves as Chair of the Orthopaedic Service and Stephen P.

Klein's line or the line of Klein is a virtual line that can be drawn on an X-ray of an adolescent's hip parallel to the anatomically upper edge of the femoral neck. It was the first tool to aid in the early diagnosis of a slipped capital femoral epiphysis (SCFE), which if treated late or left untreated leads to crippling arthritis, leg length discrepancy and lost range of motion. It is named after the American orthopedic surgeon Armin Klein at Harvard University, who published its description and usefulness in 1952. Subsequent modification of its use has increased the sensitivity and reliability of the tool.
John Ivor Pulsford James was a British orthopaedic surgeon. He was professor of orthopaedic surgery at the University of Edinburgh from 1958 to 1979. Most commonly known as "JIP", he was secretary then president of the British Orthopaedic Association which later awarded him its honorary fellowship. James attracted orthopaedic specialists to work in Edinburgh, encouraging them to develop an interest in a specialist area of orthopaedics, and in this way he was able to establish a comprehensive regional orthopaedic service. He made contributions to hand surgery and surgical treatment of scoliosis, and was a prime mover in promoting specialist training and qualification in orthopaedic surgery in the UK.
Sir Herbert John Seddon was an English orthopaedic surgeon. He was Nuffield Professor of Orthopaedic Surgery at the University of Oxford, where his work and publications on peripheral nerve injuries gained him an international reputation. His classification of nerve injuries forms the basis of that in use into the 21st century. He went on to become director of the new Institute of Orthopaedics in London and subsequently the first Professor of Orthopaedics in the University of London. In this role he directed basic science research into orthopaedic conditions and developed postgraduate training in orthopaedic surgery. He was President of the British Orthopaedic Association, and was knighted in 1964 for services to orthopaedics.
Gopal Krishna Vishwakarma, more popularly known as G K Vishwakarma, was an eminent orthopedic surgeon, academician and public health administrator.

Ruth Wynne-Davies or Ruth Blower (1926–2012) was a British medical doctor and scholar of orthopaedics. She researched and wrote about clubfoot and scoliosis.
Regional acceleratory phenomenon (RAP) is a sudden acceleration of normal tissue processes in reaction to noxious stimuli. It has been exploited in treatments such as the healing of atrophic or oligotrophic nonunions and surgically facilitated orthodontic therapy.
Justin Peter Cobb is a British professor of orthopaedic surgery at Imperial College London, known for introducing medical robotics into orthopaedic surgery. He is a member of the Royal Medical Household and was royal orthopaedic surgeon to the Queen. He is on the staff at King Edward VII's Hospital (KEVII) and is civilian advisor in orthopaedics to the Royal Air Force (RAF). His research has also included themes relating to designing new devices such as for ceramic hip resurfacing, 3D printing in orthopaedics, and training in surgical skills. He is a director of the MSk laboratory based in the Sir Michael Uren Hub.
Brian Davies is a British emeritus professor of medical robotics at Imperial College London. He developed Probot, the first robotic device to operate upon a human being. Later, he developed the haptic based robotic assistant known as 'Acrobot', the first haptic based robot to be used in orthopaedic surgery. He is a Fellow of the Royal Academy of Engineering.
