Knee replacement surgery. Close-up of an operation being carried out to replace an artificial knee joint that failed due to an obese patient's weight. At upper right a surgeon is holding the old 'hinge' femoral implant component that has just been removed. The tibial implant area (white) is at centre right. Layers of skin and fat (yellow) are also seen. For a sequence showing an X-ray and photographs of the operation, see images C014/7729 to C014/7735.
