M67.36: Transient synovitis Lower leg

The thin membrane of a joint capsule or a tendon sheath in your lower leg or knee has become inflamed.

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.

Joints are encased in a joint capsule. A tendon sheath is a covering for the tendon. It cushions the tendon and contains a small amount of fluid. This reduces friction between the tendon and its surroundings. Joint capsules and tendon sheaths have a thin membrane lining inside.

Inflammations of the thin membrane of joint capsules or tendon sheaths can be caused by pathogens or toxic substances.

When the thin membrane of a joint capsule or tendon sheath becomes inflamed, it can be painful. It may also be that you are no longer able to move the affected area of your body properly.
