How to straighten O-shaped legs

Some friends have bow legs due to their own bone problems, which makes patients feel inferior. Patients with bow legs should relax first and consult a doctor to see if they can be corrected through physical therapy.

What causes bow legs?

1. Tubular bone growth defects

Tubular bones mainly refer to the long bones in the body, such as the femur. The main method of long bone formation is endochondral ossification, but there is also intramembranous ossification. In the area where long bones are formed, hyaline cartilage is first formed by mesenchyme. Its shape is similar to that of the long bones to be formed, and is called cartilage rudiments. As the embryo grows, the cartilage gradually grows larger and thicker, and degenerates and is gradually replaced by bone. When growth defects occur, it can lead to infertile development of long bones, weakened strength, and easy deformation, causing bow legs.

2. Knee cartilage development disorder

Cartilage is composed of cartilage tissue and its surrounding perichondrium. Cartilage tissue is composed of chondrocytes, matrix and collagen fibers. If the surface cartilage of the knee joint is poorly developed, the joint stress will change, leading to joint deformation and O-shaped legs.

3. Abnormal bone density, cortical structure and metaphyseal modeling

During bone growth, various factors, such as rickets, osteoporosis and other diseases, can lead to a decrease in bone density, abnormal cortical bone structure and epiphyseal plasticity, which can weaken bone strength, making fractures or bone morphology changes more likely to occur or develop into bow legs.

How to correct o-shaped legs

1. Eight-step correction method. Step backward, making sure your heel lands first and your path is straight. Take eight steps at a time.

2. Method to exercise the inner leg muscles: separate your feet as wide as shoulders, slightly bend your feet inward, and bend your knees inward when squatting and standing up. Do 20 times in a set, 2 to 4 sets a day. You don't need to squat completely.

3. Correct the direction of the femur. Lie flat on your back with your feet bent, your calves and thighs at a 45-degree angle, and your hips lifted so that your upper body and thighs are in the same plane.
