Without strong, tight ligaments to connect the femur to the tibia, the knee joint would be too loose. knee joint synovial femoral condyles articulate with tibial condyles; reinforced by intracapsular ligaments (anterior cruciate & posterior cruciate), a capsular ligament (tibial collateral ligament), and an extracapsular ligament (fibular collateral ligament); contains medial & lateral menisci intracapsularia ... system > Bony joints > Synovial joint; Diarthrosis > Ligaments ... Intra-capsular ligaments provide stability but permit a far larger range of motion than extracapsular ligaments. The posterior popliteal region of the knee is supported by a complex array of extracapsular ligaments external to the joint capsule and two intracapsular ligaments within it. Fibrous capsule of knee joint is a complex structure which is made up by a collection of adjacent ligaments. Lateral Structures that penetrate the capsule are…. There is a remarkable . • The synovial membrane of the knee joint attaches to the margins of the articular surfaces and to the superior and inferior outer margins of the menisci.

This joint has intracapsular structures which add to its strength. These include the three bones of the knee joint — the femur, tibia, and patella — several attaching muscles and tendons, the ligaments joining the bones together, and the structures contained within the joint itself.
