Your knee is the largest joint in your body and one of the most complex. The bones that make up the knee include the lower end of the femur (thighbone), the upper end of the tibia (shinbone), and the patella (kneecap). Other important structures that make up the knee joint include articular cartilage, synovium, meniscus, and ligaments. The articular cartilage e. This slippery substance helps your knee bones glide smoothly across each other as you bend or straighten your leg. The knee joint is surrounded by a thin lining called synovium. This lining releases a fluid that lubricates the cartilage and reduces friction during movement. Two wedge-shaped pieces of meniscal cartilage act as “shock absorbers” between your femur and tibia. Different from articular cartilage, the meniscus is tough and rubbery to help cushion and stabilize the joint. Bones are connected to other bones by ligaments. The four main ligaments in your knee act like strong ropes to hold the bones together and keep your knee stable. In many cases injuries involve more than one of these main structures. Some of the main injuries involve, fractures, sprains, ligament tears and dislocations. Your surgeon at Beach Orthopaedics Specialty Institute is highly skilled in knee arthroscopy and complex reconstructions.
