All-Suture Anchor–Enhanced Capsulorrhaphy Versus Simple Longitudinal Capsulorrhaphy in the Treatment of Moderate-to-Severe Hallux Valgus: a retrospective cohort study

Background The ideal surgical technique for treating moderate-to-severe hallux valgus (HV) is unclear. Surgical methods that effectively restore the balance of soft tissues around the first metatarsophalangeal (MTP) joint are necessary. This study compared osteotomy combined with either all-suture anchor–enhanced capsulorrhaphy (AEC) or simple longitudinal capsulorrhaphy (SLC). Methods Ninety-five patients with moderate-to-severe HV were divided into the AEC group or the SLC group. Demographic data, clinical scores, and radiological parameters collected before surgery, at 3 months after surgery, and at the last follow-up were retrospectively analyzed, and complications and recurrence were monitored. Results All patients showed significant improvement in clinical scores and radiological parameters ( p  < 0.05). The AEC group exhibited better HV correction than the SLC group, as well as significantly better distal metatarsal articular angles and joint congruency ( p  < 0.05). Conclusion Both AEC and SLC were safe and effective techniques for correcting moderate-to-severe HV, although AEC exhibited a greater corrective ability and achieved better joint congruency. Levels of Evidence: Level III.
