AK (Above Knee) Amputees
Your residual limb consists of muscle and soft tissue that will need to be shaped and reduced in volume as soon as possible after surgery.  A shrinker sock, also called a compression wrap, is used on the residual limb and is designed to apply the greatest amount of pressure at the lower end of the limb, gradually reducing pressure as you move upward.  This pressure is what will reduce the swelling and shape your residual limb.  Your age and overall health will ultimately determine the length of time it will take for the swelling to go down.

The shrinker sock in an elastic sock with an attached waistband, and is sized to fit your residual limb.  You should check the sock 3-4 times a day to be sure it is pulled up properly.  If there is excess space at the bottom of the sock, the limb will swell into that space.

BK (Below Knee) Amputees
For below knee amputations, an immediate post-operative prosthesis (IPOP) can be used on the residual limb.  This is a cast that extends above the knee and is put on the residual limb immediately after the operation.  This cast cannot be removed and is usually worn for the first two weeks following surgery. A lightweight pylon may be used to connect the cast to an artificial foot.

The cast serves several functions.  It prevents excessive swelling and also prevents knee flexion contractures, which occur when the leg is bent for a long period of time and will cause the knee to lock in position.  The cast also protects the limb from bumps and falls.

When the IPOP is removed, a removable rigid dressing (RRD) is applied. T his is another type of cast, which can be removed and should be done daily to clean and inspect the limb. The RRD extends to the knee and protects from injury.  As the swelling goes down, socks can be worn under the RRD to fill the extra space.  Sometimes socks may be used in conjunction with the RRD to further reduce swelling.

Below knee amputees can also use a compression sock, which controls swelling by providing pressure from the bottom of the limb, decreasing toward the top.
