The diagram above shows the bones and ligaments that make up the synovial hinge joint, commonly known as the knee.
The four bones that make up the knee joint are the femur (thigh bone), the tibia (shin bone), the fibula (lateral shin bone), and the patella (knee cap). Connective tissue known as articulating cartilage lines the ends of the tibia and femur, and the anterior of the patella, reducing friction and providing a surface for smooth contact during flexion, extension or rotation.
The knee joint also contains the medial meniscus and lateral meniscus. These …show more content…
The joint is likely to swell and bruise. The use of the joint is typically painful and difficult to do.
3rd Degree sprain: a severe injury where the ligament tears completely, causing swelling and sometimes internal bleeding. This makes the joint is unstable and unable to bear weight. Usually, following a 3rd Degree sprain, pain is not felt because all the pain fibres are torn because of the injury.
Popping or snapping feeling or sound at the time if a ligament is completely torn
Bleeding inside the joint
Swelling of your knee - the degree of swelling will depend on the severity of the injury
Pain in your knee - the degree of pain will depend on the severity of the injury
Tenderness around your knee when touched - mild tenderness in minor sprains, severe tenderness if a ligament is torn
Not being able to use the knee normally - movement severely reduced if completely torn, relatively good amount of movement if more minor sprain
A feeling that the knee is unstable - may cause limping depending on severity
Bruising around the knee can sometimes occur, but not always - may take time for bruising to develop Knee ligaments may be injured due to: sharp changes in direction landing at at angle on the joint after a
