Definition
X-legs are axial deviations from the normal axis. In contrast to bow legs, the axis of bow legs deviates inwards. When viewed from the front, the impression of an “X” is created.
X- legs are axial deviations from the norm. The legs deviate to the side in the middle and give the impression of an “x”. X-legs can be either congenital or acquired.
Besides pain, knee joint arthrosis can also be a complaint. The knee joint is worn down on one side. The diagnosis is primarily made clinically, i.e. based on the symptoms and appearance as well as a specific treadmill analysis. The X-ray image is also indicative, especially in the case of arthrosis of the joint. The treatment of the underlying disease as well as surgical treatment is available for therapy.
Causes
Bow legs can be congenital or acquired. Congenital knock-knees: In congenital knock-knees, weaknesses of the connective tissue are the most common. A malformation of the bones themselves can also be congenital.
The knock-knees are “normal” in children at the age of 2.5 years and should grow straight again in the further course. Acquired knock-knees: 1. acquired knock-knees can be symptoms of various basic diseases: 2. incorrect growth 3. after bone fractures (medically post-traumatic) 4. also in paralysis, knock-knees can develop if the direction of growth is changed by an asymmetrical muscle pull.
- Rickets (vitamin D deficiency)
- Bone fragility after the menopause
- Hormone Disorders
- Inflammations
- Overweight
- Tumors
Symptoms
It is not only cosmetic problems with bow legs in adults that are problematic, above all the increased strain on the knee joint is the consequence. The asymmetrical load on the knee joint results in increased wear and tear on the outer part of the joint. This not only wears down the joint cartilage and thus causes premature wear, but the outer meniscus (especially the outer meniscus) also suffers. The result is knee joint arthrosis. The X-leg often occurs together with a bent foot and a leg bent backwards (so-called genu recurvaturum).
