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.
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.

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.
Rotationplasty was first performed by Joseph Borggreve in 1927. [2] He performed the procedure on a 12-year-old boy who suffered from tuberculosis.However, the procedure was not well known until 1950, when Dutch orthopedist Cornelis Pieter van Nes (1897–1972) reported the results of rotationplasty procedures.

The transposition of two triangular flaps The incisions are designed to create a Z shape with the central limb aligned with the part of the scar that needs lengthening or re-aligning. The traditional 60° angle Z-plasty will give a theoretical lengthening of the central limb of 75%. [ 1 ]
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".
