Twenty fresh\u2010frozen cadaver knees (12 cadavers) were tested. We employed the Rigidfix Cross Pin device (Mitek, Norwood, MA), designed to use two biodegradable pins (PLA, length 42\u00a0mm, diameter 2.7\u00a0mm). Instead of PLA pins, we used color coded metallic pins. Femoral tunnel drilling and cross\u2010pin guide insertions were performed through the anteromedial portal. We gave three positions to the cross\u2010pin guide: 0\u00b0, 45\u00b0 and 90\u00b0 slope, referring to the horizontal plane. Per each position, we inserted two metallic pins. We recorded and subdivided the pin holes, in three different groups: Group A (0\u00b0); B (45\u00b0); C (90\u00b0 of slope). Then a wide dissection has been implemented. Group A: 6\u00a0knees (30%) had two pins inside the cartilage of the lateral femoral condyle; 10\u00a0knees (50%) had one pin inside the cartilage; and 4\u00a0knees (20%) had both pins out of the cartilage. Group B: 7\u00a0knees (35%) had two pins inside the cartilage; 12\u00a0knees (60%) had one pin inside the cartilage; and one knee (5%) had both pins out of the cartilage. Group C: 7\u00a0knees (35%) had two pins inside the cartilage; and 13\u00a0knees (65%) had one pin inside the cartilage. The risk of chondral injury, using this technique, is high: from 80% (group A) to 100% (Group C) to have at least one pin inside the cartilage. The use of Rigidfix via AM portal is not recommended for routine ACL reconstruction.<\/jats:p>","DOI":"10.1007\/s00167-007-0459-9","type":"journal-article","created":{"date-parts":[[2007,12,21]],"date-time":"2007-12-21T13:53:19Z","timestamp":1198245199000},"page":"275-278","source":"Crossref","is-referenced-by-count":13,"title":["ACL reconstruction using the Rigidfix femoral fixation device via the anteromedial portal: a cadaver study to evaluate chondral injuries"],"prefix":"10.1002","volume":"16","author":[{"given":"Filippo","family":"Castoldi","sequence":"first","affiliation":[{"name":"Department of Orthopaedics and Traumatology \u201cUmberto I\u201d Hospital University of Turin C.so Duca degli Abruzzi 15 10128 Turin Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Davide Edoardo","family":"Bonasia","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology \u201cUmberto I\u201d Hospital Turin Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antongiulio","family":"Marmotti","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology \u201cUmberto I\u201d Hospital Turin Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Federico","family":"Dettoni","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology \u201cUmberto I\u201d Hospital Turin Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roberto","family":"Rossi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology \u201cUmberto I\u201d Hospital University of Turin C.so Duca degli Abruzzi 15 10128 Turin Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,12,22]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s001670100223"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199710000-00014"},{"key":"e_1_2_5_4_1","first-page":"135","article-title":"Endoscopic single\u2010incision anterior cruciate ligament reconstruction using patellar tendon autograft","volume":"16","author":"Hardin GT","year":"2003","journal-title":"J Knee Surg"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00167\u2010005\u20100019\u20100"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/00001433\u2010200404000\u201000008"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546503261714"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/0749\u20108063(95)90104\u20103"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00167\u2010005\u20100705\u2010y"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.1177\/03635465030310020401"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00167\u2010004\u20100509\u20105"},{"key":"e_1_2_5_12_1","unstructured":"SaliniV ColucciC PalmieriD(2005)Artroscopia di ginocchio: principi generali della tecnica.In: Pellacci F (ed) Chirurgia artroscopica dell'arto inferiore Mattioli 1885"},{"key":"e_1_2_5_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0749\u20108063(98)70141\u20100"}],"container-title":["Knee Surgery, Sports Traumatology, Arthroscopy"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/link.springer.com\/content\/pdf\/10.1007\/s00167-007-0459-9.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/link.springer.com\/article\/10.1007\/s00167-007-0459-9\/fulltext.html","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/esskajournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1007\/s00167-007-0459-9","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,19]],"date-time":"2025-10-19T12:52:47Z","timestamp":1760878367000},"score":1,"resource":{"primary":{"URL":"https:\/\/esskajournals.onlinelibrary.wiley.com\/doi\/10.1007\/s00167-007-0459-9"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,12,22]]},"references-count":12,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2008,3]]}},"alternative-id":["10.1007\/s00167-007-0459-9"],"URL":"https:\/\/doi.org\/10.1007\/s00167-007-0459-9","archive":["Portico"],"relation":{},"ISSN":["0942-2056","1433-7347"],"issn-type":[{"value":"0942-2056","type":"print"},{"value":"1433-7347","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007,12,22]]}}}
