We then formed two subgroups providing a statistical midrange of the metatarsophalangeal angle, intermetatarsal angle I-II and degree of arthrosis of the first metatarsophalangeal joint to obtain comparable collectives of 40 Keller and 36 chevron procedures.<\/jats:p>\n                  <jats:p>The postoperative AOFAS score averaged 85.4 for the Keller procedure and 83.0 for chevron patients. The metatarsophalangeal angle was improved to an average of 11.0\u00b0 and 13.9\u00b0, the intermetatarsal angle to values of 8.8\u00b0 and 9.4\u00b0, respectively. The patient's overall satisfaction rated \u201cvery satisfied\u201d and \u201csatisfied\u201d in 92.5% and 94.4%, respectively.<\/jats:p>\n                  <jats:p>The main reason for dissatisfaction was pain. Compared to the literature, the good long-term results in this series following resection arthroplasty are attributed to the routine use of the \u201cCerclage fibreux\u201d technique. This contemporary type of the Keller procedure is still a valuable surgical procedure for older patients with minor functional expectations. Excellent outcome after chevron osteotomy was not only seen in younger patients with minor deformities, but also in an older population. The chevron osteotomy should not be restricted to younger patients. The combination of the chevron distal metatarsal osteotomy with a distal soft-tissue procedure does not increase the risk of clinically manifest avascular necrosis of the metatarsal head and helps to correct higher metatarsophalangeal and intermetatarsal angles.<\/jats:p>","DOI":"10.1177\/107110070202300406","type":"journal-article","created":{"date-parts":[[2017,1,13]],"date-time":"2017-01-13T05:58:07Z","timestamp":1484287087000},"page":"321-329","source":"Crossref","is-referenced-by-count":39,"title":["Keller Procedure and Chevron Osteotomy in Hallux Valgus: Five-Year Results of Different Surgical Philosophies in Comparable Collectives"],"prefix":"10.1177","volume":"23","author":[{"given":"Wolfgang","family":"Schneider","sequence":"first","affiliation":[{"name":"General Orthopaedic Department II, Orthopaedic Hospital Vienna -Speising, Vienna, Austria."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karl","family":"Knahr","sequence":"additional","affiliation":[{"name":"General Orthopaedic Department II, Orthopaedic Hospital Vienna -Speising, Vienna, Austria."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2002,4,1]]},"reference":[{"key":"bibr1-107110070202300406","doi-asserted-by":"publisher","DOI":"10.1007\/BF00452962"},{"key":"bibr2-107110070202300406","doi-asserted-by":"publisher","DOI":"10.1177\/107110079701800405"},{"key":"bibr3-107110070202300406","first-page":"450","volume":"30","author":"David Bar T.","year":"1991","journal-title":"J.
