Operative method. A semitendinosus tendon graft was collected. Oblique skin incision was made centring the fibular head and opened, confirming the common fibular nerve. Bone tunnels were made according to the method described by Kobbe et al. [1]. The obtained semitendinosus tendon was passed through the transtibial and transfibular tunnels and fixed to the pes anserinus using a stapler with maximum manual force at the knee joint flexion angle of 30°.
