Background: Tenotomy of tendon Achilles is one of the major components of Ponseti method and necessary to complete correction in about 80 to 90 % of patients, it is safely procedure can be done in outpatient office as percutaneous technique under local anesthesia or in operative room under general anesthesia as mini-open technique. This study was designed to evaluate effect of tendoachillis tenotomy either percutaneous or open on continuity of tendoachillis by open evaluation in relapsed club foot. Patient & method: This study was conducted on 18 individuals. They were divided into 2 equal groups: Group I: containing 9 patients both sex had previously percutaneous tenotomy is done and Group II: 9 patients both sex had previously open tenotomy is done. Results: percutaneous technique found easy dissection in 6 patients (66.7%) and difficult dissection in 3 patients (33.3%) and continuity found central and regular contour in 7 patients (77.8%) and fibrotic mass in 2 patients (22.2%), open technique found easy dissection in 5 patients (55.6%) and difficult dissection in 4 patients (44.4%) and continuity found central and regular contour in 5 patients (55.6%) and fibrotic mass in 4 patients (44.4%), Conclusion: the techniques tenotomy of tendoachillis had no effect on continuity of tendoachillis either open or closed techniques in management of club foot.
