The aim of this study was to analyse the relationship between femoral tunnel positioning and the prevalence of PFA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This was a single\u2010centre study of patients undergoing an isolated MPFLr between 2006 and 2011 with a minimum of 10 years of follow\u2010up. Outcomes assessed were the presence of PFA on radiographs, recurrence of instability requiring revision surgery and patient\u2010reported outcomes, including Kujala, Tegner and IKDC scores. Tunnel positioning was assessed on postoperative radiographs using two radiographic methods: Sch\u00f6ttle's point and the grid method to localise the femoral tunnel. Patients were grouped based on tunnel positioning and compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Fifty patients were analysed at a mean follow\u2010up of 12.4 years. Thirty\u2010three patients (66%) had a femoral tunnel position within 7\u2009mm of Sch\u00f6ttle's point and 39 (78%) within the anatomic quadrant, with the most common location according to the grid method in D4 (28%) and E4 (26%), respectively. Thirty\u2010seven patients (74%) had a satisfactory (&gt;80 versus &lt;80) Kujala score at long\u2010term follow\u2010up. None of the examined tunnel assessment methods demonstrated a significant relationship with Tegner, Kujala or International Knee Documentation Committee scores. Patients with a femoral tunnel position &gt;7\u2009mm outside Sch\u00f6ttle's point\u00a0or were considered to be in a nonanatomic position were not significantly more likely to result in unsatisfactory Kujala scores at the last follow\u2010up. Tunnel positioning and the other tested parameters were not found to be significantly associated with the development of PFA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>No correlation between femoral tunnel position and risk of PFA or poor outcomes was observed in patients undergoing isolated MPFLr at long\u2010term follow\u2010up. The impact of femoral tunnel placement on long\u2010term outcomes in patients with PFI may be less significant than originally considered.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence<\/jats:title>\n                    <jats:p>Level IV.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/ksa.12264","type":"journal-article","created":{"date-parts":[[2024,5,21]],"date-time":"2024-05-21T02:14:36Z","timestamp":1716257676000},"page":"2806-2817","source":"Crossref","is-referenced-by-count":7,"title":["Nonanatomical femoral tunnel positioning in isolated MPFL reconstruction is not associated with an increased risk of patellofemoral osteoarthritis after a minimum follow\u2010up of 10 years"],"prefix":"10.1002","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-3231-5444","authenticated-orcid":false,"given":"Julien","family":"Erard","sequence":"first","affiliation":[{"name":"Orthopaedics Surgery and Sports Medicine Department, FIFA Medical Center of Excellence, Croix\u2010Rousse Hospital Lyon University Hospital Lyon France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-5605-994X","authenticated-orcid":false,"given":"Joris","family":"Olivier","sequence":"additional","affiliation":[{"name":"Orthopaedics Surgery and Sports Medicine Department, FIFA Medical Center of Excellence, Croix\u2010Rousse Hospital Lyon University Hospital Lyon France"},{"name":"Department of Orthopaedic Surgery Centre Hospitalier Bois de l'Abbaye Seraing Li\u00e8ge Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stanislas","family":"Gunst","sequence":"additional","affiliation":[{"name":"Orthopaedics Surgery and Sports Medicine Department, FIFA Medical Center of Excellence, Croix\u2010Rousse Hospital Lyon University Hospital Lyon France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jobe","family":"Shatrov","sequence":"additional","affiliation":[{"name":"Orthopaedics Surgery and Sports Medicine Department, FIFA Medical Center of Excellence, Croix\u2010Rousse Hospital Lyon University Hospital Lyon France"},{"name":"Department of Orthopaedic Surgery Sydney Adventist Hospital Sydney New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C\u00e9cile","family":"Batailler","sequence":"additional","affiliation":[{"name":"Orthopaedics Surgery and Sports Medicine Department, FIFA Medical Center of Excellence, Croix\u2010Rousse Hospital Lyon University Hospital Lyon France"},{"name":"IFSTTAR, LBMC UMR_T9406, Claude Bernard Lyon 1 University Universit\u00e9 de Lyon Lyon France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00e9bastien","family":"Lustig","sequence":"additional","affiliation":[{"name":"Orthopaedics Surgery and Sports Medicine Department, FIFA Medical Center of Excellence, Croix\u2010Rousse Hospital Lyon University Hospital Lyon France"},{"name":"IFSTTAR, LBMC UMR_T9406, Claude Bernard Lyon 1 University Universit\u00e9 de Lyon Lyon France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elvire","family":"Servien","sequence":"additional","affiliation":[{"name":"Orthopaedics Surgery and Sports Medicine Department, FIFA Medical Center of Excellence, Croix\u2010Rousse Hospital Lyon University Hospital Lyon France"},{"name":"LIBM\u2014EA 7424, Interuniversity Laboratory of Biology of Mobility Claude Bernard Lyon 1 University Lyon France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,5,20]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1186\/s43019-023-00187-1"},{"key":"e_1_2_12_3_1","doi-asserted-by":"crossref","unstructured":"Batailler C.
