M25.26: Flail joint Lower leg

You have significantly reduced stability in your knee.

The knee joint connects the thighbone (femur) to the lower leg. The kneecap is also part of the knee joint. There are 2 bones in the lower leg. These bones are called the tibia (shinbone) and fibula. There is also a joint immediately below the knee joint between the tibia and fibula. The joint just below your knee may also be less stable than usual.

Joints are held together by ligaments and a tight capsule made up of connective tissue. The muscles around the joint and the bones involved in the joint are important for the joint’s stability.

Joints may be less stable if they are overextended. The capsule or the ligaments in the joint can get damaged when this happens. Disorders or injuries can also make joints less stable. When the affected joints are subjected to loads, they can feel unsteady. Your gait may then be less steady than usual.
