Clubfoot treatment in China before and after the advent of the Ponseti technique: a historical narrative review

Congenital clubfoot (CF) was first described by Hippocrates in approximately 400 B.C. In ancient China, manipulations were widely used to correct CF, but the outcomes were frequently unsatisfactory with residual deformity even if corrective devices were used. The advent of aseptic surgery and anesthesia has favored the development of different surgical procedures to manage children with CF. Surgical treatment became extremely popular in China during the years 1960-1990 due to the good clinical foot appearance post-surgery. However, the poor mid- to long-term results of surgical treatment facilitated the return of conservative treatment, i.e., the Ponseti technique. Over the past decade, the Ponseti technique has become very popular in China. The Ponseti technique is essentially conservative and it is based on a good understanding of CF pathophysiology. Casts are changed once a week and Achilles tenotomy is performed if equinus persists at the end of treatment. Although highly successful on the short to mid-term, the Ponseti technique is not able to completely eradicate surgery, and recurrence is still possible. As the etiology of CF is still unclear, the first mission for doctors and researchers all over the world is to truly understand the pathogenesis of the deformity. Even though genetics seems to play an important role, successful gene therapy is still a distant goal. This narrative review aims to investigate the history of CF treatment in China, to describe its tortuous process and to potentially inspire new ideas to create new effective methods of treatment.
