X-legs / O-legs
Not only are cosmetic X / O legs problematic in adults, but especially the increased burden on the knee joint is the result.
In the long term, all high-grade inferior positions, whether X-leg or O-leg, lead to premature wear of the articular cartilage, so that at an early age an arthrosis of the knee joint (knee arthrosis / gonarthrosis) must be expected.
In the kyBoot / kyBounder, you can strengthen your stabilizing foot and knee muscles and integrate your leg-axis training into your daily routine without the need for additional time.
Bending in medicine means a deviation of a limb mass from the normal position (neutral 0 position).
The varus position is referred to when the angle (medial) to the body center is less than the normal at the bones or joints (at the knee joint at the o-leg (genu varum), for example, less than 186 ° (from the Axes enclosed by the upper and lower limbs).
The valgus position is referred to when the angle to the body center is greater than the norm (at the knee joint of the X-leg (genu valgum), for example, greater than about 186 °, on bones or joints.
The angulation of the (distally) limb distant from the body is considered; in the description of a varus / valgus position in the knee, the angulation of the lower leg is considered.
X-legs are rarely congenital. In the case of congenital X-legs, connective tissue weaknesses are mainly concerned. Even by a defective shape of the bones themselves may be congenital.
X-legs can be corrected by night rails or gypsum.
As a rule, X-legs are a consequence of knee joints. The misalignment of the feet causes the legs to reach an oblique position to the knee. The lower leg is guided like a lever obliquely to the knee and affects normal growth.
In rickets, the bone structure is disrupted by a deficiency of vitamin D. The bone does not cure properly and can not support body weight. The consequences can be both X-legs and O-legs.
Also the child paralysis can cause X-legs.
In newborns and infants, O-legs are completely normal and spontaneously recede.
Among other things, trauma can be acquired. Also basic illnesses such as overweight (overload), rickets, hormone disorders, tumor or inflammations can be the cause for O-legs.
Some sports favor the development of O-legs. These are above all sports, in which the muscle group of the so-called abductors on the thighs side is more strongly demanded during training and are therefore more trained than the internal adductors. The best known example is football.
O-leg complaints include pain. These are usually caused by osteoarthritis and uneven wear on the knee joint. If the O-leg only occurs on one side, a curvature of the spine may develop as a compensation which the body wishes to perform.
In an O-leg, the inner thigh bone roll (Condylus medialis femoris) is more heavily loaded. As a result, the internal meniscus is more strongly stressed and a gonarthrosis directed to the center comes. Learn how to fix bow legs here
In the worst case, X-legs can lead to knee and hip problems later.
The result of X-legs can also be arthrosis of the knee joint (gonarthrosis). In an X-leg, the outer thigh bone roll is more heavily loaded. As a result, the external meniscus is more strongly stressed and a lateral gonarthrosis occurs.
The therapy is based on the causes and can range from the treatment of the underlying basic disease to the operation.
Special foot-adjusting insoles and gymnastics (physiotherapy) are used to counteract the deficit.
Depending on the severity of the disease, ultimately the method of operative therapy must be taken.
The more frequently the foot muscles are trained, the faster the foot and knee position improves and pain decreases.
Specific initial actions for leg axis misalignment (X-legs / O-legs)
In existing foot weakenings, e.g. Kinky feet, it is initially a challenge for the feet to stand up on the soft-elastic kybun material. It may happen that after a short gestation period, you get tired and tilt to the side. If you try to correct this, you can strengthen your stabilizing foot muscles and thus counteract the foot and knee deficiencies.

The following adaptations of the standard execution of the interval walkings are important for an axis misalignment:
Focus on slow exercises, since execution is more controlled
Variant for slow exercise: go backwards (stability given by the transverse arch in the forefoot)
We advise you to wear the kyBoot without orthopedic footwear, as an active stabilization training of the foot. The foot musculature takes several months, with regular training, until it is sufficiently strong to go several hours in the kyBoot. You can wear the normal shoes with inserts as relief between. A continuous wear of the kyBoot can at the beginning (in the first weeks / months), after years of longing, the feet overstrain.
Insoles are a passive support for the foot, and in no way improve the foot situation in the long term. We recommend that the orthopedic insoles do not wear constantly. Listen best to your body, who tells you what is good for him, and when he needs a break.
Make sure that you apply the sole evenly in the kyBoot and the foot stands upright on the sole. So you have a favorable leg axis and also less an “inward kinking” of the feet and knees.
If you are very tired, have pain, or can not correct a lateral tipping of the foot, it is time to insert a short kybun break.
Do not take too long steps, which facilitates a good footing in kyBoot. This will tilt you less strongly inside.
Some people feel too unstable in the kyBoot. In this case, we advise you to try kyBoot models, some higher-cut models give more stability. We also recommend the second generation of the second generation, which is slightly wider in the midfoot area and therefore provides more safety when walking (consult the kybun specialist shop).
If you are still unsure about the kyBoot, we advise you to use kyBounder. The kyBounders are available in 3 different thicknesses; This allows you to choose the thickness where it is best for you (the thicker – the more unstable – the more intense the workout).
In addition, the kyBounder has the option, if you need additional support, to hold onto a fixed object.
If you have any further questions, please contact a kybun dealer, who will be happy to advise you personally.
