Recently, an arthroscopic modification of the Brostr\u00f6m operation (AMBO) was developed; many studies have shown that there are no significant differences in clinical and radiological outcomes between the two surgical methods. However, no studies have been conducted comparing the two surgical methods in terms of return to play (RTP) time. This study assesses the time to RTP and the functional clinical outcomes. Materials and Methods: Sixty patients were enrolled from January 2012 to July 2014. They were segregated into two cohorts: the AMBO group comprised 30 patients, while the OMBO group comprised another 30 patients. Each participant underwent standardized treatment and rehabilitation regimens and RTP time was measured using seven questions that explored the times to return of painless walking, running, jumping, squatting, climbing stairs, and rising up on the heels and toes. We compared the time intervals from the onset of instability to the date of surgery. Clinical outcomes were evaluated before the surgery, 6 weeks after surgery, and 6 months after surgery. The assessments included the American Orthopedic Foot &amp; Ankle Society (AOFAS) ankle\u2013hindfoot score, the pain visual analog scale (VAS) score, subjective satisfaction with rehabilitation, and activity level. Results: In terms of RTP, AMBO was associated with a shorter interval to walking without pain (7.07 \u00b1 2.96 weeks) relative to OMBO (11.03 \u00b1 8.58 weeks). No disparities were observed in the time to return to play (RTP) between OMBO and AMBO. While there were no discrepancies in the 6-month postoperative AOFAS or VAS scores, the 6-week postoperative VAS score was notably lower in the AMBO group compared to the OMBO group. AMBO provided a faster RTP in terms of two of the seven questions in a group exhibiting high-level physical activity. The rate of subjective satisfaction with rehabilitation was higher for AMBO than for OMBO. Conclusions: Aside from walking, the duration to return to play and the clinical outcomes were similar between AMBO and OMBO treatments for lateral ankle instability. AMBO is a good treatment option and should be carefully considered for athletes with lateral ankle instability. AMBO demonstrated positive outcomes in a group with higher activity levels compared to others, particularly in terms of time to RTP, subjective satisfaction, and postoperative pain.<\/jats:p>","DOI":"10.3390\/medicina60060921","type":"journal-article","created":{"date-parts":[[2024,6,3]],"date-time":"2024-06-03T12:19:46Z","timestamp":1717417186000},"page":"921","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["All-Inside Arthroscopic and Open Techniques of the Modified Brostr\u00f6m Procedure for the Treatment of Lateral Ankle Instability: Comparison of the Times to Return to Play"],"prefix":"10.3390","volume":"60","author":[{"given":"Sang Heon","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Soonchunhyang University Hospital Bucheon, 170, Jomaru-ro, Wonmi-gu, Bucheon-si 14584, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3699-2238","authenticated-orcid":false,"given":"Sung Hwan","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Soonchunhyang University Hospital Bucheon, 170, Jomaru-ro, Wonmi-gu, Bucheon-si 14584, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung Bum","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Bonebridge Hospital, 214, Dogok-ro, Gangnam-gu, Seoul 06272, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seong Rok","family":"Oh","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Gurosamsung Orthopedic Surgery Clinic, 204, Gyeongin-ro, Guro-gu, Seoul 04323, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seung Jin","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Soonchunhyang University Hospital Bucheon, 170, Jomaru-ro, Wonmi-gu, Bucheon-si 14584, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Young Koo","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Soonchunhyang University Hospital Bucheon, 170, Jomaru-ro, Wonmi-gu, Bucheon-si 14584, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2279","DOI":"10.2106\/JBJS.I.01537","article-title":"The epidemiology of ankle sprains in the United States","volume":"92","author":"Waterman","year":"2010","journal-title":"J.
