The video shows a medical x-ray image of a human knee. The x-ray is in black and white and shows the bones of the knee. There is a metal device attached to the bones, which is likely a prosthetic or artificial joint. The device has several screws and plates holding it in place. The x-ray is being examined by a person using a pen to point out different parts of the device. The person is likely a doctor or a medical professional. The video does not show any movement or action, as it is a still image.
