Sir John Charnley
Sir John Charnley (1911 – 1982) was an English orthopaedic surgeon.
Sir John Charnley was a master surgeon, innovator and bio-engineer, recognised as the founder of modern hip replacement (total hip arthroplasty)
Charnley was the first to use cold-curing acrylic cement (polymethylmethacrylate, PMMA); developed the ‘Low frictional torque arthroplasty’; and developed the concept of laminar air flow to eradicate a systemic infection problem in his hospital.

Medical Eponyms
Charnley hip prosthesis (1950)
Low frictional torque arthroplasty. Charnley recognized that high forces exerted on a hip implant contributed to loosening over time. He found that a stainless steel ball on polytetrafluoroethylene had a coefficient of friction similar to the normal joint. In addition he reduced the femoral head size from 40 mm (Moore type) to 22 mm in order to further reduce the frictional force.
