Cartilage damage caused by traumatic injuries, ageing, or degradative diseases leads to impaired loading resistance and progressive degeneration of both the articular cartilage and the underlying subchondral bone. Since the tissue has limited self-repairing capacity due its avascular nature, restoration of its mechanical properties is still a major challenge. Tissue engineering techniques have the potential to heal osteochondral defects using a combination of stem cells, growth factors, and biomaterials that could produce a biomechanically functional tissue, representative of native hyaline cartilage. However, current clinical approaches fail to repair full-thickness defects that include the underlying subchondral bone. Moreover, when tested <jats:italic>in vivo<\/jats:italic>, current tissue-engineered grafts show limited capacity to regenerate the damaged tissue due to poor integration with host cartilage and the failure to retain structural integrity after insertion, resulting in reduced mechanical function. The aim of this review is to examine the optimal characteristics of osteochondral scaffolds. Additionally, an overview on the latest biomaterials potentially able to replicate the natural mechanical environment of articular cartilage and their role in maintaining mechanical cues to drive chondrogenesis will be detailed, as well as the overall mechanical performance of grafts engineered using different technologies.<\/jats:p>","DOI":"10.3389\/fbioe.2021.603408","type":"journal-article","created":{"date-parts":[[2021,1,27]],"date-time":"2021-01-27T07:23:21Z","timestamp":1611732201000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":81,"title":["Influence of the Mechanical Environment on the Regeneration of Osteochondral Defects"],"prefix":"10.3389","volume":"9","author":[{"given":"Sarah","family":"Davis","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marta","family":"Roldo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gordon","family":"Blunn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gianluca","family":"Tozzi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tosca","family":"Roncada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,1,27]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1999","DOI":"10.1093\/humrep\/dez139","article-title":"Tissue stiffness at the human maternal-fetal interface","volume":"34","author":"Abbas","year":"2019","journal-title":"Human Reproduct."},{"key":"B2","doi-asserted-by":"publisher","first-page":"2994","DOI":"10.1177\/0363546520949849","article-title":"Long-term results of arthroscopic matrix-assisted autologous chondrocyte transplantation: a prospective follow-up at 15 years","volume":"48","author":"Andriolo","year":"2020","journal-title":"Am.
