Although both all-inside and inside-out lateral meniscal repair techniques place sutures very close to the lateral geniculate artery, the inside-out technique is riskier as extra-articular knot tying can cause artery obliteration when suturing the part of the meniscus immediately lateral to the popliteal hiatus. Therefore, all-inside meniscal repair technique shows less risk of injury to the major blood supply of the lateral meniscus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
