Background: This study aimed to analyze the clinical results after fixation of tibialis posterior tendon using endobutton technique and to determine whether this technique provides enough stability to permit active range of motion, healing, maintain strength and eliminate the need for braces to improve the gait. Methods: This prospective study was undertaken to assess the use of endobutton technique in fixation of tibialis posterior tendon transfer. All patients included in this study were managed and followed up at Kasr Al-Ainy Hospital in the period from June 2016 to June 2018. All cases of foot drop were treated using tibialis posterior tendon transfer and fixation by endobutton technique. The study was conducted on 30 patients aged from 15 - 50 years and the mean age was 33.7 years. Out of the 30 studied patients, 24were males (80 %) and 6 were females (20%). All patients were followed up for a minimum period of 6 months; the maximum period of follow up was 12 months with an average period of 7.9 months. Lengthening of the Achilles tendon was performed first, if the foot could not easily be passively dorsiflexed to 10{u00B0} beyond neutral.Results: This study reviewed the results of treatment of foot drop presented in 30 patients treated using posterior tendon transfer and all of the transfers were performed through the interosseous route. The distal attachment of the tibialis posterior tendon in this study was fixated by endobutton technique. All patients were able to complete the study and were included in the analysis. 16 cases got excellent score (53.33 %), eight cases were good (26.67%), five cases were fair (16.67%) and one case was poor (3.33%) at final follow up
