If you have trouble bending your knee, or you can’t, it may be flexum knee which is a fairly common knee disorder. How does it manifest itself? What are the causes of flexum knee and how to treat it? We will enlighten you on this knee pathology which can affect any category of people throughout their lives.
What is a flexum knee and what are the symptoms?
The flexum knee, also called knee flexion, results in the inability of the knee joint to reach its full extension. If you are unable to fully straighten your knee, you may be suffering from a flexum knee. This disorder can be transient or permanent. To identify it, the doctor will first examine you while standing. People with knee flexion usually experience discomfort or even pain when walking. A lying examination then checks whether the knee flexum can be reduced by attempting to extend the leg. If it is not reducible, the doctor can measure the angulation. The lying examination also makes it possible to identify any swelling or effusion and to assess the pain felt by the patient. A rheumatologist or orthopedic surgeon can confirm the diagnosis and initiate appropriate treatment.
What Are the Causes of Knee Flexum?
The causes of knee flexum are diverse. In most cases, it occurs as a result of trauma to the knee (fracture or knee sprain ). It can also appear following a ligamentoplasty (replacement of the ruptured ligament) or be the consequence of a popliteal cyst located at the back of the knee. Poor hip position can also cause the knee to flex, as can an uneven lower limb that causes the longer leg to bend in an attempt to rebalance the pelvis. a knee flexion can also occur when immobilization of the flexed knee is maintained for too long. Finally, it is not uncommon to see cases of knee flexum in patients withknee osteoarthritis .
the flexum knee treatment varies depending on the patient. If it results from an unevenness of the lower limbs, a plantar orthosis is very effective in restoring balance and correcting the knee flexum on the longer leg. In cases of more severe forms, the doctor may prescribe a knee brace to control the range of motion when flexing and extending the knee. If the knee flexum has appeared following cruciate ligament surgery, it is sometimes necessary to perform a new procedure. Anyway, it is almost always essential to do rehabilitation with a physiotherapist to treat knee flexion. Over the course of the sessions, the patient can repeat the exercises at home. It is recommended to do a few minutes each day, the goal being to work on the elasticity of the tissues and to strengthen the muscles.
Can we prevent knee flexion?
In order to limit the risk of flexum knee after an operation, it is advisable to avoid leaving your leg at rest with the knee semi-flexed, even if it may be relieving at first. If you are wearing a brace, make sure it is positioned correctly to keep your knee in the correct position. For patients who have suffered from knee flexion in the past, there are simple exercises to do at home that will continue to strengthen the knee muscles and work on the elasticity of the tissues. These exercises can be recommended by a physiotherapist. Likewise, it is recommended to regularly practice a gentle physical activity (swimming, walking, cycling), in order to reduce the stiffness of the knee and to fight against osteoarthritis which is often linked to flexum knee.
the flexum knee is a pathology that can occur throughout life and have different causes. It can in particular be treated through rehabilitation or with the wearing of orthoses. It is advisable to consult a doctor at the onset of knee pain or in case of discomfort. Regular practice of gentle sports or specific exercises can limit the risk of knee flexion.
