The lateral meniscus is one of two semilunar fibrocartilaginous structures in the knee joint that act as shock absorbers, enhance joint stability and aid in the distribution of synovial fluid. Together with the medial meniscus, the lateral meniscus provides a concave surface for the convex femoral condyles to articulate superior to the relatively flat tibial plateaus.[1] These structures are also involved in load transmission.[2] The menisci also serve to lubricate the knee joint.[3] Damage to the menisci can lead to the development of osteoarthritis of the knee.[3] Older individuals often have meniscal damage without obvious symptoms of osteoarthritis.[3]
