A new technique in spring ligament reconstruction using medial half of posterior tibial tendon is demonstrated as a means of supporting the arch. In addition a new concept of double bundle PTT reconstruction based on anatomical attachments of original PTT is presented with the goal of obtaining the full function of PTT.

Introduction: Posterior tibial tendon reconstruction frequently involves transfer of the flexor digitorum longus (FDL) tendon to the navicular and debridement of the diseased portion of the posterior tibial tendon as well as a calcaneal osteotomy and possibly a lateral column lengthening. If the posterior tibial tendon muscle appears to have some contractile property then it is anastamosed to t...

PURPOSE The purpose of this study was to evaluate the effect of the anatomic double-bundle reconstruction (ADBR) of the posterior cruciate ligament (PCL) with 2 femoral tunnels and 2 tibial tunnels. METHODS Eight fresh-frozen human knees were used. Bone tunnels were created based on the PCL anatomic footprints. A 9-mm looped semitendinosus and gracilis tendon for anterolateral bundle reconstr...

We present the operative technique and clinical results of concomitant reconstruction of the medial collateral ligament (MCL) and the posterior oblique ligament for medial instability of the knee using autogenous semitendinosus tendon with preservation of the tibial attachment. The semitendinosus tendon graft between the screw on the medial epicondyle and the tibial attachment of the graft was ...

BACKGROUND We previously developed a novel technique using an alternate soaking process that improves tendon-bone healing by hybridizing the tendon graft with calcium phosphate (CaP). However, the effects of the CaP-hybridized tendon graft on anatomic single-bundle anterior cruciate ligament (ACL) reconstruction remain unclear. PURPOSE To determine the effects of CaP-hybridized tendon grafts ...

Posterior tibial tendon dysfunction is considered one of the most common causes of progressive adult acquired flatfoot deformity. The etiology leading to the dysfunction of posterior tibial tendon remains controversial. The purpose of this study was to quantify strain on the posterior tibial tendon in cadaver feet exhibiting hyperpronation caused by flexible instability of the talotarsal joint ...

Unlike the Achilles tendon, the posterior tibial tendon does not typically undergo acute rupture. We report two cases of posterior tibial tendon tears occurring in young, athletic individuals (<30 years old) that required operative intervention before the patients could return to competitive sports. We believe that these are the first two reports of posterior tibial tendon tears occurring in th...

Background: The purpose of this study was to introduce a technical tip for the preparation of tibial tunnel in a posteriorcruciate ligament (PCL) reconstruction to reduce the chance of popliteal artery injury and duration of the surgery.Methods: This study included 18 patients who underwent PCL reconstructions at Imam Khomeini University Hospital,Tehran, Iran, between 2016 and...

We studied the vascular pattern of human posterior tibial tendons by injection techniques and immunohistochemically using antibodies against laminin. The intravascular volume of the posterior tibial tendon was determined using a new method of injection of a solution of 99mTc and gelatin ink into the lower legs of cadavers. Three segments of 1 cm length from different regions of the human poster...
