The retinaculum was released 2 cm medial to the superior pole of the patella down to the anteromedial portal. At a mean follow-up of 2.7 years (range, 1-8 years), all knees were evaluated, and the results were graded according to the Merchant and Mercer rating scale.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The mean age of the patients was 25 years (range, 15-38 years), and the mean duration of the subluxations before surgery was 28 months (range, 6-48 months). In all 7 patients (9 knees), the medial release relieved their medial subluxation and knee pain, and there were 6 excellent and 3 good results. There were no complications or further realignment surgery needed after this procedure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>An arthroscopic medial retinacular release will successfully treat painful medial subluxation of the patella.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/0363546507299445","type":"journal-article","created":{"date-parts":[[2007,3,16]],"date-time":"2007-03-16T21:40:06Z","timestamp":1174081206000},"page":"1180-1187","source":"Crossref","is-referenced-by-count":31,"title":["Results of Arthroscopic Medial Retinacular Release for Treatment of Medial Subluxation of the Patella"],"prefix":"10.1177","volume":"35","author":[{"given":"Brian D.","family":"Shannon","sequence":"first","affiliation":[{"name":"Department of Orthopedics and Rehabilitation, University of Wisconsin, Madison, Wisconsin"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James S.","family":"Keene","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Rehabilitation, University of Wisconsin, Madison, Wisconsin"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2007,7,1]]},"reference":[{"key":"bibr1-0363546507299445","doi-asserted-by":"publisher","DOI":"10.1016\/S0968-0160(98)00024-6"},{"key":"bibr2-0363546507299445","doi-asserted-by":"publisher","DOI":"10.1016\/S0968-0160(03)00006-1"},{"key":"bibr3-0363546507299445","doi-asserted-by":"publisher","DOI":"10.1177\/036354658701500508"},{"key":"bibr4-0363546507299445","first-page":"162","volume":"16","author":"Biedert RM","year":"1994","journal-title":"J Sports Traumatol"},{"key":"bibr5-0363546507299445","doi-asserted-by":"publisher","DOI":"10.1053\/otsm.2001.25170"},{"key":"bibr6-0363546507299445","doi-asserted-by":"publisher","DOI":"10.1016\/0968-0160(95)00009-E"},{"key":"bibr7-0363546507299445","unstructured":"EppleyRA Medial patellar subluxation.
