Therefore, the authors are required to reconsider the expression regarding the incidence of iatrogenic hallux varus in the second paragraph. \u3000 \u2192\uff08Response\uff09\u3000I corrected from \u201cvery low\u201d to \u201c not very low\u201d&nbsp; in the revised manuscript.  \n<b>Case report<\/b> 1.JSSF hallux scale consists of three major items, which are pain, function, and alignment. The JSSF scale used in the present study consists of five items, including pain, deformity, ROM, gait, and ADL, which are used for JSSF RA foot and ankle scale (Ref 1). The authors are required to explain the reason why they used JSSF RA scale instead of hallux scale.   \u2192\uff08Response\uff09\u3000In the present case, we evaluated JSSF RA foot and ankle scale for the functional outcome because the surgery was performed in not only hallux but also lesser toes.   2.How did the authors evaluate ROM of the hallux? Although the authors mentioned as \u201cthe MTP joint was very stiff\u201d and \u201cextension contracture\u201d, the item for ROM was 15 (out of 15 points) preoperatively. The flexion of the hallux was mentioned as -10 in the legend of figure 2, and -30 in the main text.  \u2192\uff08Response\uff09 Thank you so much for the precious comment. We reconfirmed the manuscript and legends related to range of motion of MTP joint (preoperatively). Actually, passive extension of MTP joint was 90 &deg;and passive flexion was -30 &deg;. The range of motion was 60&deg;, so this condition was neither \u201cstiff\u201d nor \u201cextension contracture\u201d but \u201climited range of motion\u201d. So, we corrected the legend of Figure 2 from \u201c-10&deg;\u201c to \u201c-30&deg;\u201d. In addition, the item of ROM was corrected from 15 (out of 15 points) to 13. The range of motion of IP joint was also corrected in the manuscript as follows; \u201c,but the IP joint remained flexible (-20&deg;in extension and 90&deg;in flexion)(Figures 2A-2D). &nbsp;   3.In the 7\n<sup>th<\/sup>&nbsp;paragraph, it is also desirable to address the documentation regarding lesser toe shortening osteotomy in more detail.  \u2192\uff08Response\uff09\u3000Dorsal curved skin incisions were applied in between the 2\n<sup>nd<\/sup> and the 3\n<sup>rd<\/sup> metatarsals and between the 4\n<sup>th<\/sup> and 5\n<sup>th<\/sup> metatarsals. Wounds were deepened and extensor digitorum brevis tendons were identified and partially resected. Distal metatarsal regions were subperiosteally released and shortening oblique osteotomy were performed with 45-degrees tilted to the metatarsal longitudinal axis for the 2\n<sup>nd<\/sup> through 5\n<sup>th<\/sup> toes. The osteotomized thickness were 7 mm. Then, distal fragment was flipped dorsally and osteophyte in the metatarsal head was totally removed and rasped. A Kirschner wire of 1.2 mm in diameter was inserted into the metatarsal, and proximal phalanx, mid phalanx, and distal phalanx for each toe. Three weeks after the insertion, these wires were removed and weight bearing and gait exercises were performed using arch support.&nbsp;  \n<b>Discussion<\/b> 1.The third paragraph (starting with \u201cAkhtah et al\u201d..) consisting of two sentences may be unnecessary. \u2192 We deleted the 3\n<sup>rd<\/sup> paragraph in Discussion part.  2.\u3000In the following four paragraphs (4\n<sup>th<\/sup>&nbsp;to 7\n<sup>th<\/sup>), salvage procedures for iatrogenic hallux varus were discussed. However, some of the description referring Leemrijse et al was redundant. Adding the documentation of the indication for MTP preservation as well as MTP arthrodesis will provide readers with a better understanding of treatment algorithm advocated by Leemrijse.  \u2192 \uff08Response\uff09Thank you so much for the precious comment. I corrected the part as follows;  \u201cFor procedures of MTP joint preservation, soft tissue release and tendon transfer method using extensor hallucis longus tendon or abductor hallucis longus tendon are used. For soft tissue release, medial capsule release or intermetatarsal space release &nbsp;&nbsp;&nbsp;&nbsp; For tendon transfers, 2 methods such as a dynamic transfer and a static transfer are known. The dynamic transfer means transfer with muscle body and the static transfer means transfer with out muscle body. Both transfers compensate for the incompetent lateral collateral ligament. Extensor hallucis longus tendon transfer is selected for a dynamic transfer with or without interphalangeal joint fusion. Abductor hallucis tendon transfer is also used. For static tendon transfer, abductor hallucis tendon or artificial implant (TightRope) is selected.\u3000 When MTP joint is unstable or limited range of motion, MTP joint cannot be preserved , so MTP joint arthrodesis is selected. The present case demonstrated that MTP joint congruity was not so good because of the joint instability and that MTP joint degeneration was clearly detected (Figure 4). Therefore, MTP joint arthrodesis was performed. \u201c.  3.Was there fibular sesamoid remained? In the paragraph 10, the authors mentioned as \u201cFibular sesamoid was also released..\u201d On the other hand, fibular sesamoidectomy was supposed to be performed 21 years prior to the revision surgery.  \u2192\u3000(Response) Thank you so much for the comment. I reconfirmed the operative record. I corrected from fibular sesamoid to tibial sesamoid. The released sesamoid was tibial one.","URL":"https:\/\/f1000research.com\/articles\/12-344\/v2#referee-comment-11458","order":1,"name":"referee-comment-11458","label":"Referee Comment","group":{"name":"article-reports","label":"Article Reports"}},{"value":"10.5256\/f1000research.168017.r300623, Inderjeet  Singh Rikhraj, Singapore General Hospital, Outram Rd, 26 Jul 2024, version 2, indexed","URL":"https:\/\/f1000research.com\/articles\/12-344\/v2#referee-response-300623","order":2,"name":"referee-response-300623","label":"Referee Report","group":{"name":"article-reports","label":"Article Reports"}},{"value":"<b>Naoki Kondo<\/b>; \n<i>Posted: 27 Jul 2024<\/i>; Dear, reviewer 2,&nbsp;  Thank you for your comment.
