The definition of genu varus is easily confused by the pathological morphology that is taken for granted: the definition of genu varus is named not by the direction of the angle formed by genu varus, but by the turning direction of the calf and tibia. Knee varus with the knee angle pointing outward is often mistaken for genu valgus. The corrective methods of O-leg are: surgery, instruments, splint, leggings, exercise, correcting insoles, etc.
This operation is suitable for patients with very serious O-leg or already complicated with osteoarthritis and joint pain. The advantage of surgery is passive treatment and immediate correction, without perseverance and persistence. The defect is that the surgical techniques are different, and most of them need osteotomy, which is painful, risky and expensive.
1. External fixator plus inverted U-shaped osteotomy of tibial tubercle.
The advantages of this method mainly include: simple and safe osteotomy, fast bone healing, not easy to delay healing, easy to master the angle of plastic correction with external fixator, accurate bone healing angle and easy to adjust. Patients can move on the ground during the treatment, and the muscles of lower limbs will not atrophy.
2. Inverted U-shaped osteotomy of tibial tubercle and external fixation with tubular plaster after operation.
According to statistics, the complete correction rate of O-leg deformity can reach more than 96%.
The principle of non-surgical correction methods is basically the same, which is to relax the medial collateral ligament of knee joint and restore the stable structure of medial and lateral knee joint. So as to make the tibia rotate outwards and achieve the purpose of correction.
The advantages of non-surgical correction are low cost and low risk, while the disadvantages are active treatment, slow effect and long-term persistence. Without perseverance, it is impossible to achieve the goal of correction.
The correction method of "O" leg is as follows:
(1) Stand up straight, put your feet together, bend your knees and do squats and handstands for 20 ~ 3o times each.
(2) Bend down, and make circular movements with both hands and knees to the left and right for 20-30 times.
(3) Keep your feet slightly open, bend over, and tuck your knees in your hands to stop your knees from leaning inward. Stop for 10 second each time and do it for 5 ~ 10 times.
(4) Stand with two feet in parallel. First, take the heel as the axis and do toe abduction and internal rotation; Then do heel abduction and internal rotation 20 ~ 30 times with tiptoe as the axis.
(5) Sit in a chair and try to hold the book with your calf for a while. If you tie your knees with rubber bands, the effect will be more obvious.
(6) Sit on your knees, your waist collapses, your feet slowly move outward, and your waist will gradually straighten. Do 15 ~ 20 times.
How to correct O-leg
You can use different parts of leg muscles by slightly changing your standing posture, which is the biggest feature of squat. Knees and thighs are close together when squatting, which is very effective for correcting O-legs. The lower you squat, the better.
Methods: Hands akimbo, upper body upright, legs apart 15-20cm, toes slightly outward, knees together when inhaling, slowly squat down, squat down as deep as possible and pause for one minute, feeling leg muscles tense. When exhaling, slowly open your knees, stand up straight and repeat 10 times. O-leg correction exercise 1. Eight-step correction method. Take a step back, pay attention to your heels first, and walk straight. Take eight steps at a time.
2. The method of exercising the inner muscles of the leg: the feet are shoulder-width apart, the feet are slightly flexed, and the knees are bent to do squats and stand up. Do 2 ~ 4 groups every day, 20 times in a group. You don't need to squat completely.
