Knee Joint 3D

  • Description

    • * The knee is the largest and most complex joint of the body. The complexity is the result of the fusion of three joints in one.
    • * It is formed by the lateral femorotibial, medial femorotibial, and femoropatellar joints.
    • * It permits flexion, extension, and some gliding and rotation in the flexed position of the knee.                                                                                                                                                                                                                                                                                                                                 

Intracapsular ligaments

  • Anterior Cruciate ligament:

    • *It lies inside the knee joint capsule but outside the synovial cavity of the joint.
    • * It arises from the anterior intercondylar area of the tibia and passes upward, backward, and laterally to insert into the medial surface of the lateral femoral condyle.
    • * It prevents forward sliding of the tibia on the femur and prevents hyperextension of the knee joint.                                                                                                                                                                                                                                                      
  • Posterior Cruciate ligament:
    • * It lies outside the synovial cavity but within the fibrous joint capsule.
    • * It arises from the posterior intercondylar area of the tibia and passes upward, forward, and medially to insert into the lateral surface of the medial femoral condyle.
    • * It prevents backward sliding of the tibia on the femur and limits hyperflexion of the knee.                                                                                                                 
  • Medial Meniscus:
    • * It lies outside the synovial cavity but within the joint capsule.
    • * It is attached to the medial collateral ligament and interarticular area of the tibia.
    • * It acts as a shock absorber and lubricates the articular surfaces by distributing synovial fluid in a windshield-wiper manner.                                                                                                                                                                                                 
  • Lateral Meniscus:
    • * It lies outside the synovial cavity but within the joint capsule.
    • * It is attached to the medial collateral ligament and interarticular area of the tibia.
    • * It acts as a shock absorber and lubricates the articular surfaces by distributing synovial fluid in a windshield-wiper manner.                                                                                                                                                                                   
  • Transverse ligament:
    • * It binds the anterior horns of the lateral and medial semilunar cartilages.                                                                                                                         

Extracapsular ligaments

  • Medial Collateral ligament:

    • * It is broadband that extends from the medial femoral epicondyle to the medial tibial condyle.
    • * It is firmly attached to the medial meniscus, and its attachment is of clinical significance because injury to the ligament results in concomitant damage to the medial meniscus.
    • * It prevents medial displacement of the two long bones and thus abduction of the leg at the knee.                                                                                                                                                                                                                                              
  • Lateral Collateral ligament:
    • * It is a rounded cord separated from the lateral meniscus by the tendon of the popliteus muscle.
    • * It extends between the lateral femoral epicondyle and the head of the fibula.
    • * It becomes taut on extension and limits extension and adduction of the leg.                                                                                  
  • Patellar ligament:
    • * It is a flattened fibrous band that is continuation of the quadriceps femoris tendon.
    • * Its portion may be used to repair the anterior cruciate ligament.
    • * It extends from the apex of the patella to the tuberosity of the tibia.                                                                                                                                    
  • Arcuate Popliteal ligament:
    • * It arises from the head of the fibula arches superiorly and medially over the tendon of the popliteus muscle on the back of the knee joint and fuses with the articular capsule.                                                                                                                                                                                                
  • Oblique Popliteal ligament
    • * It is an oblique expansion of the semimembranous tendon and passes upward obliquely across the posterior surface of the knee joint from the medial condyle of the tibia.
    • * It resists hyperextension of the leg and lateral rotation during the final duration of the extension.                                                                                                                                                                                                                                                
  • Popliteus Tendon:
    • * It arises as a cord-like tendon from the lateral femoral condyle. It runs between the lateral meniscus and the capsule of the knee joint deep to the fibular collateral ligament.
