Objective: To clinically evaluate, the effectiveness of percutaneous tenotomy of Achilles tendon using a 16 gauge needle in clubfoot treatment by ponseti technique. Material and methods: forty five affected foot were prospectively evaluated in Twenty five patients with ctev attending orthopedics OPD in K R Hospital, Mysore and treated conservatively using ponseti technique between June 2016 and November 2017.out of forty five affected feet ,thirty nine feet required tenotomy and percutaneous tenotomy done using a 16 gauge needle and assessed clinically. Results: all 39 feet successfully managed, the reported complications of conventional tenotomy by knife [excessive bleeding, pseudo-aneurysm or neurovascular compromise] were not encountered with this technique. Conclusion: This percutaneous tenotomy technique using a 16 needle is a simple procedure, safe and very effective and gives predictable results without any complications which were reported with tenotomy by knife.Keywords: Percutaneous tenotomy, Achilles tendon, 16 gauge needle, management, clubfoot Introduction Clubfoot or CTEV( congenital talipes equino-varus ) with an incidence of about 1 in 1000 live births [1,2] makes it one of the most commonly encountered congenital deformity in clinical practice. Equinus at ankle joint, varus of hind foot, fore-foot adduction, and mid-foot cavus are the four components of this deformity [3][4][5][6] . Historically, Hippocrates introduced the conservative management for clubfoot in around 400 BC [10,11] . Later, Kite introduced a method [12] in 1993, which included manipulation and casting technique, but the success rate was poor [7,8,13] . Later, in 1963 Ponseti developed a conservative method, called as Ponseti technique, which consists of serial manipulation and casting followed by tendoachilles tenotomy, if needed to correct residual equinus and casting and it takes about four to five weeks to achieve the full correction of all four components of the deformity [14,15] . Ponseti management, over the past two decades has become accepted throughout the world as the most effective and less expensive treatment of ctev. The technique involves serial manipulation and casting and possible percutaneous tendoachilles tenotomy. However, in about 85% of the cases there was a residual equinus deformity which needed further correction by tenotomy of Achilles tendon [16][17][18][19] Originally, as Ponseti described, tenotomy is performed using a surgical blade, such as a no.11 or no.15, or any other small blade, such as an ophthalmic knife. However, complications related to the procedure, such as excessive bleeding [23] , formation of a pseudo-aneurysm [24] and neurovascular injuries [25] , were described. To avoid these complications, many modifications have been introduced. Recently, new technique by using wide bore surgical needle is increasingly used which was first described by Minkowitz et al. [20,21,22] . The technique of performing tenotomy with a needle may have advantages over other tenotomy techniques, as ...
