Summary
<p>In orthopedic surgery, tendon transfers are the top title of surgical techniques used in many different indications such as nerve damage, motor unit dysfunction, congenital anomalies and deformities. One of the most common application areas of tendon transfer procedures is the tendon transfer procedure used in the foot and ankle. Tendon fixation techniques have been defined that vary depending on the location where the transferred tendon will be implanted after tendon transfer, patient-related variables, and the postoperative rehabilitation process. Based on these variables, many tendon transfer methods can be used for the same indication. Independent variables such as synergistic different muscles being preferred, diversity in the area to be transferred considering different purposes, and the ability to detect the transferred tendon with different methods have revealed different tendon transfer options and the advantages and disadvantages of these different options. Ideal tendon transfer fixation method; It must be biological, cost-effective, accessible and easily applicable.</p><p>Anchor, interference screw, endobutton are some of the currently accepted techniques in active clinical use. To roughly summarize, in the anchor fixation method, fixation is achieved with an anchor placed inside the bone and strong stitches attached to this anchor. In the endobutton method, which is another technique, the tendon is moved to the area where it will be transferred with the help of a tunnel prepared in the bone, and its fixation in this position is provided by an implant that will keep it suspended in the tunnel. The fixation method after Tibialis anterior tendon transfer that we recommend is to tie the two strong sutures used to carry the Tibialis anterior together after they come out of different tunnels in the medial foot. By placing a part of the transferred tendon into the tunnel, an osseo-tendinous healing will occur, and strong sutures will undertake tendon fixation until this healing occurs. In the described technique, costly implants are not required, and in addition to being a biological fixation, the risk of damage to anatomical structures will be minimal.</p><p>In our research, it was aimed to compare the tunnel method, which has not been compared before, with two methods defined and accepted in the literature in tibialis anterior tendon transfer, which is a common procedure, and to make a biomechanical and anatomical comparative analysis between the methods.</p><p><br></p>
