The purpose of the present study was to determine if a postoperative rehabilitation program helped to improve weightbearing of the first ray after chevron osteotomy for correction of hallux valgus deformity. Materials and Methods: Twenty-nine patients with a mean age of 58 years with mild to moderate hallux valgus deformity who underwent a chevron osteotomy were included. Postoperatively, the patients received a multimodal rehabilitation program including mobilization, manual therapy, strengthening exercises and gait training. Preoperative and one year postoperative plantar pressure distribution parameters including maximum force, contact area and force-time integral were evaluated. Additionly the AOFAS score, ROM of the first MTP joint and plain radiographs were assessed. The results were compared using Student's t-test and level of significance was set at p &lt; 0.05. Results: In the great toe, the mean maximum force increased from 72.2 N preoperatively to 106.8 N 1 year after surgery. The mean contact area increased from 7.6 cm<jats:sup>2<\/jats:sup> preoperatively to 8.9 cm<jats:sup>2<\/jats:sup> 1 year after surgery and the mean force-time integral increased from 20.8 N\u2217sec to 30.5 N\u2217sec. All changes were statistically significant ( p &lt; 0.05). For the first metatarsal head region, the mean maximum force increased from 122.5 N preoperatively to 144.7 N one year after surgery and the mean force-time integral increased from 42.3 N\u2217sec preoperatively to 52.6 N\u2217sec 1 year postoperatively ( p = 0.068 and p = 0.055, respectively). The mean AOFAS score increased from 61 points preoperatively to 94 points at final followup ( p &lt; 0.001). The average hallux valgus angle decreased from 31 degrees to 9 degrees and the average first intermetatarsal angle decreased from 14 degrees to 6 degrees ( p &lt; 0.001 for both). Conclusion: Our results suggest that postoperative physical therapy and gait training with a Chevron osteotomy may help to improve weightbearing of the great toe and first ray. Therefore, we believe there is a restoration of more physiological gait patterns in patients who receive this postoperative regimen. <\/jats:p><jats:p> Level of Evidence: IV, Retrospective Case Series <\/jats:p>","DOI":"10.3113\/fai.2010.0980","type":"journal-article","created":{"date-parts":[[2010,12,28]],"date-time":"2010-12-28T20:08:42Z","timestamp":1293566922000},"page":"980-986","source":"Crossref","is-referenced-by-count":20,"title":["Plantar Loading After Chevron Osteotomy Combined With Postoperative Physical Therapy"],"prefix":"10.1177","volume":"31","author":[{"given":"Reinhard","family":"Schuh","sequence":"first","affiliation":[{"name":"Innsbruck, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"suffix":"Jr.","given":"Samuel","family":"Adams","sequence":"additional","affiliation":[{"name":"Innsbruck, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefan Gerhard","family":"Hofstaetter","sequence":"additional","affiliation":[{"name":"Innsbruck, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"Krismer","sequence":"additional","affiliation":[{"name":"Innsbruck, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hans-Joerg","family":"Trnka","sequence":"additional","affiliation":[{"name":"Innsbruck, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2010,11,1]]},"reference":[{"key":"bibr1-FAI.2010.0980","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-198106000-00007"},{"key":"bibr2-FAI.2010.0980","unstructured":"2.
