This is an excerpt from Postural Correction by Jane Johnson. Genu Flexum As the name indicates, in the genu flexum flexed knee posture a person bears weight through a knee that is flexed to a greater degree than is normal when standing. Less common than genu recurvatum, it is a posture observed in the elderly or in patients who have been sedentary and their knees have been allowed to rest in a flexed position for prolonged periods. Viewed laterally, an imaginary line drawn vertically from just anterior to the lateral malleolus bisects the tibia longitudinally in normal knee posture figure 8. In the genu flexum posture the knee itself falls anterior to this line, which no longer bisects the leg figure 8.

How is it diagnosed? A bone disease or arthritis will need to be treated. During a physical exam, your doctor will observe how you stand and walk. How is genu valgum treated? Treatment for genu valgum depends on the cause and severity of your symptoms. For example, if rickets are causing your knock-knees, your doctor will likely prescribe vitamin D and calcium supplements to help restore your levels.
A typical treatment plan will include one or more of the following: Weight loss Obesity can put added stress on your knees, worsening genu valgum. Your doctor or physical therapist can evaluate your gait and suggest exercises designed to strengthen your leg, hip, and thigh muscles. Specific stretches may also be useful in relieving symptoms.
Strengthening exercises can be simple, such as leg raises while seated or lying down. As you progress with an exercise routine, you may add leg weights to make it more effective. Orthotics If your legs are of unequal length as a result of genu valgum, a heel insert into the shoe on the shorter side can equalize your leg length and help regularize your gait.
It may also relieve leg pain. For younger people, a small metal plate inserted in their knee can help direct future bone growth. This minor procedure is called guided growth surgery. The plate is removed when bone growth is corrected.
Adults may benefit from an osteotomy. This surgery uses permanent metal plates to keep bones aligned. This can adjust your leg bones and realign your knees. Knee replacement surgery is also an option for older adults.
What is the outlook for genu valgum? For older children and adults with genu valgum, a course of physical therapy and exercises can help realign their knees.
It can also strengthen surrounding muscles and avoid stress damage to other joints. In time, untreated knee misalignment can cause pain and problems in functioning.
Genu flexum, or constant flexed knee, corresponds to an attitude of the joint which cannot extend fully, for a congenital or acquired reason. Where does it come from? Genu flexum may originate from different factors, including: Leg length inequality; Poor hip positioning excessive flexion ; Immobilization of the knee, kept flexed over a long period healing of an injury ; Joint stiffness due to a diseases arthritis or a trauma fracture, sprain, tear. How can it be recognized? Since the knee cannot reach its full extension, it remains constantly flexed. In case of leg length inequality, the longer leg flexes to rebalance the pelvis. Opt for a foot orthosis In the case of leg length inequality, a foot orthosis with a heel lift can be worn to restore the balance.
