title: CONTRIBUTION TO THE ANATOMICAL STUDY OF THE CORTICOPERIOSTEAL FLAP OF THE MEDIAL FEMORAL CONDYLE.
abstract: OBJECTIVE
  to perform the anatomical study, in cadavers, of the corticoperiosteal flap of the medial femoral condyle, based on the medial genicular artery, evaluating challenges in dissection and the topographic patterns.
  
  
  METHODS
  fifteen limbs from eight cadavers were studied, ages ranging from 19 to 74 years old. They were placed at supine position, and a longitudinal incision on the medial face of the lower part of the thigh was performed, exposing medial vastus and sartorius muscles, with descendent genicular vessels being also exposed. The distance between the descendent genicular artery and the medial articular line of the knee, the diameter of the vessel, the length of the pedicle, and the presence of the fasciocutaneous branch and its location were analyzed.
  
  
  RESULTS
  the distance between the origin of the descendent genicular artery and the medial articular line of the knee ranged from 11.2cm to 14.5cm, with an average of 12.63cm. The mean artery diameter was 2.5mm (from 2.25mm to 2.75mm). The distance between the descendent genicular artery and the fasciocutaneous branch ranged from 1.0 to 1.5cm. The mean length of the vascular pedicle was 7.01cm, ranging from 5.6cm to 8.6cm.
  
  
  CONCLUSIONS
  the corticoperiosteal flap of the medial femoral condyle of the knee is easy to dissect, presents a constant vascular pedicle, with average length of 7.0cm and diameter of 2.5mm, enabling it to be indicated for microsurgical transplants.
