There are some names in surgery that you need to know – Sir John Charnley is one of them. Most widely known as the father of modern total hip arthroplasty, his contributions and inventions to the field of orthopaedics are extraordinary! Prof Charnley pioneered the first total hip replacement surgery, turning his own custom stems in his workshop. Most of the operating room proforma you see today is simply the modernised version of many of his innovations – negative pressure operating theatres, ventilated ‘moon suits’, grout cement, and the THR just to name a few. An incredible and inspirational pioneer to the field of orthopaedic surgery!
