The purpose of this study is to assess the correction in ankle dorsiflexion that can be achieved with a gastrocnemius recession. An isolated gastrocnemius release (Strayer procedure) was performed on 26 legs, in 20 consecutive patients, for clinically significant gastrocnemius equinus contracture. Ankle dorsiflexion was assessed using a validated electrogoniometer. Ankle dorsiflexion was recorded with the knee straight and with the knee bent. Measurements were recorded preoperatively, and immediately postoperatively. Measurements at an average of 55.0 days post-surgery (range, 37 to 128 days) were performed on 20 legs (15 patients).<\/jats:p>\n                  <jats:p>Results: Average preoperative ankle dorsiflexion with the knee straight was 5.1\u00b0. Average preoperative ankle dorsiflexion with the knee bent was 22.8\u00b0. Immediately following surgery the average ankle dorsiflexion with the knee straight was 23.2\u00b0. The average correction was 18.1\u00b0 and this increase was significant (p &lt; 0.0001.) In the 15 patients (20 legs) available for follow-up, the increase in ankle dorsiflexion with the knee straight was maintained (average: 24.9\u00b0).<\/jats:p>\n                  <jats:p>Patients with gastrocnemius contracture who underwent an isolated gastrocnemius release increased their ankle dorsiflexion (knee straight) by an average of 18.1\u00b0 with postoperative ankle dorsiflexion (knee straight) being equivalent (23.2 and 22.8\u00b0) to preoperative ankle dorsiflexion (knee bent). This correction appears to be maintained (23.2 vs. 24.9\u00b0) at short-term follow-up.<\/jats:p>","DOI":"10.1177\/107110070202300105","type":"journal-article","created":{"date-parts":[[2017,1,10]],"date-time":"2017-01-10T13:11:54Z","timestamp":1484053914000},"page":"26-29","source":"Crossref","is-referenced-by-count":147,"title":["The Effect on Ankle Dorsiflexion of Gastrocnemius Recession"],"prefix":"10.1177","volume":"23","author":[{"given":"Stephen J.","family":"Pinney","sequence":"first","affiliation":[{"name":"Sacramento, CA and Seattle, WA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"Jr.","given":"Sigvard T.","family":"Hansen","sequence":"additional","affiliation":[{"name":"Sacramento, CA and Seattle, WA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"Jr.","given":"Bruce J.","family":"Sangeorzan","sequence":"additional","affiliation":[{"name":"Sacramento, CA and Seattle, WA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2002,1,1]]},"reference":[{"key":"bibr1-107110070202300105","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2796.1994.tb01286.x"},{"key":"bibr2-107110070202300105","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199904000-00011"},{"key":"bibr3-107110070202300105","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-195638020-00007"},{"key":"bibr4-107110070202300105","doi-asserted-by":"publisher","DOI":"10.1177\/107110078300400307"},{"key":"bibr5-107110070202300105","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-195840060-00013"},{"key":"bibr6-107110070202300105","doi-asserted-by":"crossref","first-page":"7","DOI":"10.1097\/00003086-198312000-00003","volume":"181","author":"Bordelon RL","year":"1983","journal-title":"Clinical Ortho."},{"key":"bibr7-107110070202300105","volume-title":"Surgical and conservative foot care","author":"Bordelon RL","year":"1988"},{"key":"bibr8-107110070202300105","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.58B1.1270500"},{"key":"bibr9-107110070202300105","first-page":"249","volume":"301","author":"Damron TA","year":"1994","journal-title":"A two-part study.
