Amputation is major surgery. All the risks associated with the administration of anesthesia exist, along with the possibility of heavy blood loss and the development of blood clots. Infection is of special concern to amputees. Infection rates in amputations...
average 15%. If the stump becomes infected, it is necessary to remove the prosthesis and sometimes to amputate a second time at a higher level.
Failure of the stump to heal is another major complication. Nonhealing is usually due to an inadequate blood supply. The rate of nonhealing varies from 5–30% depending on the facility. Centers that specialize in amputation usually have the lowest rates of complication.
Persistent pain in the stump or pain in the phantom limb is experienced by most amputees to some degree. Treatment of phantom limb pain is difficult. One final complication is that many amputees give up on the rehabilitation process and discard their prosthesis. Better fitting prosthetics and earlier rehabilitation have decreased the incidence of this problem.

As the title implies, this video describes how muscles work. It shows the anatomy of the muscle in relation to bone but also the structure of muscle at the microscopic level.
In an above-the-knee amputation, three incisions are made (A). First the skin and muscle layers are cut (B). The major blood vessels are clamped and severed (C). The bone is cut with a special saw (D). Finally, the muscles are stitched over the bone, and the skin is closed over the wound (E). (Illustration by GGS Inc.)

Other Information
Amputation is the removal of a body extremity by trauma or surgery. As a surgical measure, it is used to control pain or a disease process in the affected limb, such as malignancy or gangrene. In some cases, it is carried out on individuals as a preventative surgery for such problems. A special case is the congenital amputation, a congenital disorder, where foetal limbs have been cut off by constrictive bands. In some countries, amputation of the hands or feet is or was used as a form of punishment for people who committed crimes. Amputation has also been used as a tactic in war and acts of terrorism. In some cultures and religions, minor amputations or mutilations are considered a ritual accomplishment. Unlike many non-mammalian animals (such as lizards that shed their tails), once removed, human extremities do not grow back. A transplant or a prosthesis is the only option for recovering the loss.
