[Analysis of risk factors and progress on revision surgery for postoperative recurrence of hallux valgus]

Recurrence of hallux valgus is one of the most common and difficult complications after surgery. Due to the lack of understanding of 3D deformity of hallux valgus and risk factors for recurrence, the overall recurrence rate is still high, and the choice of treatment is still controversial. Improper operation and severe deformity are known risk factors for recurrence, while the role of unstable of the first plantar train and combined flat foot deformity in the recurrence has been paid more attention by scholars at home and abroad. In addition to the first metatarsophalangeal fusion, modified Lapidus osteotomy and proximal metatarsal osteotomy have been proven to be reliable revision procedures. The purpose of this study is to summarize risk factors for recurrence of hallux valgus after surgery, and to explore the choice of revision surgery after recurrence, in order to provide guidance for prevention and management of recurrence of hallux valgus.
