A rotation flap is a semicircular skin flap that is rotated into the defect on a fulcrum point. Rotation flaps provide the ability to mobilize large areas of tissue with a wide vascular base for reconstruction. The flap must be adequately large, and a large base is necessary if a back-cut will be needed to lengthen the flap.
A positive test will show rotation of greater than 10-15° of rotation compared to the opposite knee. This is most easily assessed with a hand placed over the tibia while testing. When the patient is prone, the knee is flexed to 90° and both feet are externally rotated and compared, noting the difference from the non-injured joint.
Flaps can contain many different combination of layers of tissue, from skin to bone (see § Classification). The main goal of a flap is to maintain blood flow to tissue to maintain survival, and understanding the anatomy in flap design is key to a successful flap surgery.

In the actual procedure, the bone affected by the tumor, as well as a small part of the healthy femoral and occasionally tibia bone, is removed. A portion of the leg removed; the ankle joint is then turned 180 degrees and is reattached to the thigh. They are held together by plates and screws until they have healed naturally.

Arthroscopic debridement of TFC discus tissue. The central part of the TFC has no blood supply and therefore has no healing capacity. When a tear occurs in this area of the TFC, it typically creates an unstable flap of tissue that is likely to catch on other joint surfaces. Removing the damaged tissue (debridement) is then indicated.
Various types of tissue may be transferred as a "free flap" including skin and fat, muscle, nerve, bone, cartilage (or any combination of these), lymph nodes and intestinal segments. An example of "free flap" could be a "free toe transfer" in which the great toe or the second toe is transferred to the hand to reconstruct a thumb. [1]
The subgroup of pedicled perforator flaps, transferred in the defect by rotation is the so-called "propeller flap". Confusion concerning definition, nomenclature and classification of propeller flaps led to a consensus meeting similar to the "gent consensus meeting”. The consensus that was reached is named "the tokyo consensus".
