Modified Medial Capsulorrhaphy Using Figure-of-Eight Suture in Hallux Valgus Correction Surgery

Objective: Medial capsulorrhaphy is an important step in hallux valgus correction surgery; however, studies on this technique are limited. This study aimed to evaluate the viability and efficacy of modified medial capsulorrhaphy using figure-of-eight sutures for hallux valgus compared to the conventional technique. Methods: Retrospective analysis was performed on patients with hallux valgus, comparing a group receiving standard longitudinal capsulorrhaphy (Group 1) and a group that underwent modified capsulorrhaphy using figure-of-eight sutures (Group 2). Basic anthropometry, preoperative hallux valgus angle (HVA), immediate postoperative HVA, and 6-month postoperative HVA were recorded. An independent sample t-test was performed to investigate differences between the groups. Results: Thirty-four feet were enrolled in the study and divided into Group 1 (19 feet) and Group 2 (15 feet). There were no significant differences between the groups in terms of age, BMI, preoperative HVA, immediate postoperative HVA, and 6-month postoperative HVA (p=0.646, 0.752, 0.231, 0.792, and 0.933, respectively). However, we found that the average of HVA changes between immediate postoperative and 6-month postoperative was dissimilar (1.73 ± 2.37° Group 1 vs. 0.33 ± 1.29° Group 2, p=0.048) Conclusion: While both techniques were efficacious in decreasing HVA, modified capsulorrhaphy using the figure-of-eight technique was better at maintaining corrected HVA until 6-month postoperative period. This technique is recommended because of its efficacy and simplicity.
