The inclusion criteria were as follows: English\u2010language papers for recurrent patellar dislocation without any evident predisposing factors, clinical trial(s) with clear description of surgical technique, adult subjects, medial soft\u2010tissue surgery or MPFL reconstruction without combined surgery, and a follow\u2010up longer than 2 years. The methodological quality of all articles was assessed by 2 authors according to the Coleman methodology score.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Thirteen studies (mean Coleman methodology score value, 74.1; standard deviation, 11.5) were included in the analysis. Five studies reported the outcomes of patients undergoing medial soft\u2010tissue surgery, compared with 7 studies reporting MPFL reconstruction. Overall, 109 patients underwent medial soft\u2010tissue surgery with a minimum 2\u2010years follow\u2010up, compared with 308 patients of MPFL reconstruction. There was one direct comparative study between medial soft\u2010tissue surgery and MPFL reconstruction. Of the patients who received medial soft\u2010tissue surgery, 0 to 9.7% experienced redislocation, compared with 0 to 10.7% of the MPFL reconstruction group. The ranges of differences in Kujala scores were 23.6 to 31.7 points in patients who underwent medial soft\u2010tissue surgery and 23.11 to 38.8 points in patients who underwent MPFL reconstruction. The ranges of postoperative congruence angles were\u00a0\u221214.4\u00b0 to 8.2\u00b0 for medial soft\u2010tissue surgery and\u00a0\u22127.7\u00b0 to\u00a0\u22125.2\u00b0 for MPFL reconstruction. The ranges of postoperative lateral patellofemoral angles were 7.9\u00b0 to 9.4\u00b0 for medial soft\u2010tissue surgery and 5\u00b0 to 5.3\u00b0 for MPFL reconstruction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>All studies on medial soft\u2010tissue surgery and MPFL reconstruction for recurrent patellar dislocation without predisposing factors showed satisfactory outcomes despite the use of numerous surgical techniques, graft types, and follow\u2010up periods.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence<\/jats:title>\n                    <jats:p>Level IV, Systematic Review.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1016\/j.arthro.2015.08.012","type":"journal-article","created":{"date-parts":[[2015,11,4]],"date-time":"2015-11-04T22:24:09Z","timestamp":1446675849000},"page":"507-516","update-policy":"https:\/\/doi.org\/10.1016\/elsevier_cm_policy","source":"Crossref","is-referenced-by-count":24,"title":["Medial Soft\u2010Tissue Realignment Versus Medial Patellofemoral Ligament Reconstruction for Recurrent Patellar Dislocation: Systematic Review"],"prefix":"10.1002","volume":"32","author":[{"given":"Jae\u2010Gwang","family":"Song","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery Aerospace Medical Center Republic of Korea Air Force Cheongju\u2010si Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seung\u2010Baik","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Seoul National University Boramae Hospital Seoul Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"So\u2010Hee","family":"Oh","sequence":"additional","affiliation":[{"name":"Department of Biostatistics Seoul National University Boramae Hospital Seoul Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jae\u2010Hwi","family":"Han","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Inje University Ilsan Paik Hospital Ilsan Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daivesh","family":"Shah","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery B.
