In all three cases, an isolated MPFL reconstruction was performed with a double autogenous gracilis graft. The patellar fixation was done through bone tunnels. All three patients presented with a definite moderate to severe traumatic episode resulting in a recurrent patella dislocation and a transverse avulsion fracture at the medial rim of the patella. All three were treated by an open reduction and internal fixation with good results. No complication or recurrent dislocations occurred. We suggest that this complication is caused by the original underlying pathology such as dysplastic trochlea, abnormal TT\u2013TG, patella alta and hyperlaxity, resulting a greater reliance upon the reconstructed MPFL for patellar stability. When subjected to a severe stress, the graft, which is stronger and stiffer than the original MPFL, will cause a fracture through the medial edge of the patella. This weak area results from the previous drill holes, which act as stress risers.<\/jats:p>","DOI":"10.1007\/s00167-007-0418-5","type":"journal-article","created":{"date-parts":[[2007,11,2]],"date-time":"2007-11-02T12:15:37Z","timestamp":1194005737000},"page":"40-43","source":"Crossref","is-referenced-by-count":83,"title":["Recurrent patellar dislocation after medial patellofemoral ligament reconstruction"],"prefix":"10.1002","volume":"16","author":[{"given":"Mathieu","family":"Thaunat","sequence":"first","affiliation":[{"name":"Knee Clinic G3\u00a0Medi Clinic Die Boord 7600 Stellenbosch Western Cape South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pieter J.","family":"Erasmus","sequence":"additional","affiliation":[{"name":"Knee Clinic G3\u00a0Medi Clinic Die Boord 7600 Stellenbosch Western Cape South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2007,11]]},"reference":[{"key":"e_1_2_4_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003086\u2010200209000\u201000005"},{"key":"e_1_2_4_3_1","first-page":"33","article-title":"Surgical management of patellar instability","volume":"4","author":"Erasmus PJ","year":"2005","journal-title":"SA Orthop J"},{"key":"e_1_2_4_4_1","first-page":"317","article-title":"Les rotules basses: a propos de 128 observations","volume":"68","author":"Caton J","year":"1982","journal-title":"Rev Chir Orthop"},{"key":"e_1_2_4_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF01552649"},{"key":"e_1_2_4_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/JSA.0b013e31803035ae"},{"key":"e_1_2_4_7_1","doi-asserted-by":"publisher","DOI":"10.1177\/03635465980260012701"},{"key":"e_1_2_4_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0968\u20100160(02)00002\u20109"},{"key":"e_1_2_4_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0968\u20100160(00)00072\u20107"},{"key":"e_1_2_4_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00167\u2010005\u20100659\u20100"},{"key":"e_1_2_4_11_1","first-page":"65","article-title":"Clinical results of isolated reconstruction of the medial patellofemoral ligament for recurrent dislocation and subluxation of the patella","volume":"72","author":"Mikashima Y","year":"2006","journal-title":"Acta Orthop Belg"},{"key":"e_1_2_4_12_1","doi-asserted-by":"publisher","DOI":"10.1097\/00132588\u2010200603000\u201000004"},{"key":"e_1_2_4_13_1","doi-asserted-by":"publisher","DOI":"10.1177\/03635465980260012501"},{"key":"e_1_2_4_14_1","first-page":"24","article-title":"Biomechanical evaluation of lateral patellar dislocations","volume":"11","author":"Burks RT","year":"1998","journal-title":"Am J Knee Surg"},{"key":"e_1_2_4_15_1","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199904000-00013"},{"key":"e_1_2_4_16_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.87B1.14924"},{"key":"e_1_2_4_17_1","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-197759020-00014"},{"key":"e_1_2_4_18_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.blo.0000223995.79894.5e"},{"key":"e_1_2_4_19_1","doi-asserted-by":"publisher","DOI":"10.1097\/00132588\u2010200606000\u201000009"}],"container-title":["Knee Surgery, Sports Traumatology, Arthroscopy"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/link.springer.com\/content\/pdf\/10.1007\/s00167-007-0418-5.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/link.springer.com\/article\/10.1007\/s00167-007-0418-5\/fulltext.html","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/esskajournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1007\/s00167-007-0418-5","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,19]],"date-time":"2025-10-19T11:59:59Z","timestamp":1760875199000},"score":1,"resource":{"primary":{"URL":"https:\/\/esskajournals.onlinelibrary.wiley.com\/doi\/10.1007\/s00167-007-0418-5"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,11]]},"references-count":18,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2008,1]]}},"alternative-id":["10.1007\/s00167-007-0418-5"],"URL":"https:\/\/doi.org\/10.1007\/s00167-007-0418-5","archive":["Portico"],"relation":{},"ISSN":["0942-2056","1433-7347"],"issn-type":[{"value":"0942-2056","type":"print"},{"value":"1433-7347","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007,11]]}}}
