Femoroacetabular impingement (FAI) is an anatomic alteration of the proximal femur and\/or acetabulum leading to chondro\u2010labral damage and playing a prominent role in OA pathogenesis. Thus, treating FAI is fundamental to relieve hip pain and further joint tissue deterioration. Labral reconstruction is considered the treatment of choice, in particular using tendon allografts or autografts which, however, have some limitations. Here, we investigated the possibility to create a synthetic graft for labral reconstruction to best restore the load bearing and ready to be used in the surgical room.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The graft was designed analyzing the anatomical structures from intact tissue samples. After a preliminary screening of different polymers, silicone was selected for its flexibility and elasticity to better adhere to the implantation site. We used an FDA\u2010approved biocompatible silicone (VK100), and a mold casting was selected as a fabrication method. Cytocompatibility of VK100 was tested in\u00a0vitro with an immortalized chondrocytes human cell line (C\u201028\/I2). A cadaver lab was used to test the implantation procedure and to investigate the effects of the device transplantation on hip range of motion, translation, and resultant joint stability. To test the long\u2010term strength of the reconstruction under cyclic loading, synthetic hemipelves were prepared for biomechanical testing and subjected to 10,000\u2009cycles where deflections of up to 5\u2009mm were imposed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In vitro tests showed that up to 14\u2009days of culture C\u201028\/I2 cells were alive and adherent to VK100 surface with the formation of cell protrusions. As for cell cytotoxicity, a slight increase in LDH levels was observed at 14\u2009days, probably due to the high confluence of adherent cells. We also demonstrated with the ex\u00a0vivo procedure on cadaver that the device was suitable for arthroscopic implantation without damage or structural compromise during fixation to the acetabular bone. The range of motion and joint stability were preserved after implantation. Furthermore, the graft reconstruction successfully passed strenuous biomechanical cyclic loading. The force peak decreased by less than 10% during the test, indicating no detectable reduction of stiffness nor displacement\/failure of the graft. No sign of damage was observed after test completion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Overall, these results suggest that we have developed a functional synthetic graft that might be quickly transferred to clinical practice.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/os.70246","type":"journal-article","created":{"date-parts":[[2026,3,20]],"date-time":"2026-03-20T14:40:21Z","timestamp":1774017621000},"page":"791-800","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Hip Labral Reconstruction With a Synthetic Graft: Development and Preclinical Validation"],"prefix":"10.1111","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4556-4734","authenticated-orcid":false,"given":"Enrico","family":"Tassinari","sequence":"first","affiliation":[{"name":"2nd Orthopaedic and Traumatologic Clinic, IRCCS Istituto Ortopedico Rizzoli  Bologna Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8803-7013","authenticated-orcid":false,"given":"Mauro","family":"Petretta","sequence":"additional","affiliation":[{"name":"RegenHu Company  Villaz\u2010Saint\u2010Pierre Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2761-3862","authenticated-orcid":false,"given":"Giorgia","family":"Borciani","sequence":"additional","affiliation":[{"name":"RAMSES Laboratory, RIT Department, Research Centre Codivilla\u2010Putti IRCCS Istituto Ortopedico Rizzoli  Bologna Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7473-6868","authenticated-orcid":false,"given":"Luca","family":"Cristofolini","sequence":"additional","affiliation":[{"name":"Department of Industrial Engineering Alma Mater Studiorum\u2010University of Bologna  Bologna Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6726-3177","authenticated-orcid":false,"given":"Eleonora","family":"Olivotto","sequence":"additional","affiliation":[{"name":"RAMSES Laboratory, RIT Department, Research Centre Codivilla\u2010Putti IRCCS Istituto Ortopedico Rizzoli  Bologna Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,3,20]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-007-0061-y"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-007-0060-z"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2010.07.022"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0278-5919(05)70284-2"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546511414017"},{"issue":"7","key":"e_1_2_12_7_1","first-page":"1012","article-title":"Hip Morphology Influences the Pattern of Damage to the Acetabular Cartilage: Femoroacetabular Impingement as a Cause of Early Osteoarthritis of the Hip","volume":"87","author":"Beck M.","year":"2005","journal-title":"Journal of Bone and Joint Surgery (British Volume)"},{"issue":"6","key":"e_1_2_12_8_1","first-page":"517","article-title":"Hip Arthroscopy","volume":"29","author":"Carreira D.","year":"2006","journal-title":"Orthopedics"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.1177\/1941738117712675"},{"key":"e_1_2_12_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-009-1138-6"},{"issue":"11","key":"e_1_2_12_11_1","first-page":"1459","article-title":"Current Concepts in the Management of Femoroacetabular Impingement","volume":"87","author":"Crawford J.
