Rigid endoscopes can be used to examine various internal organs and structures, especially joints and the external surfaces of organs within the abdominal cavity, such as the ovaries. The most frequently investigated joint is the knee, primarily because damage to it is common. Investigations using rigid endoscopes are often carried out under general anaesthesia. The endoscope is inserted through a small incision made in the skin. Further small incisions may be made for other instruments, such as forceps. The internal structures may be viewed on a monitor or through an eyepiece.
