Knock knees, also called genu valgum, is when the knees angle inward and end up touching each other while the ankles stay apart. It shows up quite often in young kids, and in most cases, it sorts itself out as they grow older. Still, sometimes it continues into adulthood, or it can show up over time because of certain underlying issues. People can get it from genetics, nutritional deficiencies, or medical conditions that interfere with bone growth. For knock-knee treatment, options usually start with physiotherapy, maybe bracing, and then lifestyle adjustments, and for the really difficult situations, doctors may suggest knock-knee surgery.
What Are Knock Knees?
Genu valgum is the formal name for the condition of a child having inwardly angled legs due to their knees touching while their ankles are apart when in a standing position. Genu valgum in young children is quite common; most will grow out of this abnormality as they mature. If your child has difficulties moving or is in pain due to their knock-kneed condition when they reach maturity, they may need treatment options.
Physiological Knock Knees are typically a normal occurrence in the development of most young children, whereby their knees would appear a bit twisted inwardly but typically correct themselves naturally over time.
Pathological Knock Knees involve an underlying disorder affecting the bones (such as rickets, osteogenesis imperfecta and arthritis) and may require treatment by a physician.
A unilateral knock-kneed situation is the result of a previous injury or infection on one side of your body, thereby causing a misalignment problem with one of those legs.
Bilateral Knock Knees cause the knee joint on both legs to curve towards each other, as symmetry exists and likely is related primarily through hereditary factors and/or metabolic disorders affecting bone growth.
Treating knock-knees usually means doing a few things at once; it really depends on how bad it is, what caused it, and the patient's age. In other words, it is not always the same plan for everyone; sometimes it just kind of trends better with time, and you monitor it, other times you have to do more.
Observation and Monitoring: For little kids, especially, knock knees often sort themselves out as they grow. A clinician will typically keep an eye on the angles and function, so the situation is getting better, without doing anything major right away.
Exercise and Physical Therapy: Targeted workouts, plus physical therapy, can help a lot. They focus on strengthening the muscles around the knees, improving alignment, and easing any nagging pain. This option is commonly suggested for mild cases in children as well as adults.
Orthotic Devices: Braces, insoles, or shoe modifications can support better knee positioning. These tools can be very helpful, especially for kids who are still growing and whose bone structure may still be changing.
Medication: If the knock-knees are caused by an underlying condition such as rickets, clinicians might prescribe supplements like vitamin D and calcium to sort out the deficiency.
Weight Management: For people who are overweight, shedding extra body weight can greatly lessen the load across the knees, which may help the situation, or at least keep it from getting worse.
Surgical Intervention: When the deformity is quite severe or when other treatments haven’t worked out, surgery might be needed. The surgical choices include:
Osteotomy: This procedure means cutting and repositioning the bones so the knee alignment becomes more correct.
Guided Growth Surgery: With this approach, small metal plates are placed temporarily near the growth plates, so bone growth in children can gradually be guided back.
Total Knee Replacement: In adults who have severe knock-knees, especially when arthritis is involved, a knee replacement may become the best option.
Lifestyle Modifications: Changing everyday habits to reduce knee strain can be helpful. That could mean skipping high-impact sports and using gentler options such as swimming or cycling.
Pain Management: Simple over-the-counter pain relievers or sometimes prescribed medicines can help control discomfort that goes along with knock-knees.
The cost of knock-knee surgery in India can be from $5000 - $12000. The cost can be different depending on the type of treatment and the place where it's being performed.
What you would expect to pay for the cost of treatment includes doctor's consultations and any other tests required for the procedure, the actual procedure itself, an overnight stay in a hospital, and any therapy required after the procedure has been completed.
The symptoms of knock-knees can look a bit different from person to person, but usually, there are obvious changes in the knee alignment, along with some discomfort that feels sort of nagging or keeps coming back.
Age: Knock-knees are often seen in children roughly aged 2 to 4 years old. In many cases, the issue improves on its own as the child grows older. Still, if it keeps going past age 7, or if it shows up clearly in adulthood, then a medical review might be needed.
Genetics: If someone in the family has knock-knees or other skeletal quirks, the odds go up for the condition.
Nutritional Deficiencies: Not getting enough vitamin D and calcium in childhood can trigger rickets, which then raises the risk of knock-knees.
Obesity: Extra body weight can overwork the knee joints, and that strain may contribute to the problem or make it worse.
Injury: Any trauma to the knee, especially during the growth phase in kids, can sometimes lead to knock-knees.
Medical Conditions: Illnesses like rickets, osteomalacia, osteoarthritis, and a range of metabolic or bone-related disorders can make someone more likely to develop knock-knees.
Certainly, here are a few risk factors that may incite the onset of knock-knees or may worsen the existing ones:
Obesity: Apart from being generally unhealthy, an individual with excessive body weight would be prone to the problem of knock-knees. Carrying the additional weight would certainly put more pressure on the knees, which may result in the worsening of the problem or the appearance of knock-knees, as the strain on the joints increases.
Family History: As it was mentioned before, the genetic factor can have an impact on the occurrence of knock-knees. Those people whose family members have had knock-knees are more likely to get the condition themselves, and it may even continue after childhood.
Nutritional Deficiencies: Poor calcium and vitamin D nutrition, both of which are highly important for bone health, can be one of the paths leading to diseases like rickets, which is a knock-knees risk factor, especially for children.
Injury or Trauma to the Knee: The odds of knock-knees are very high if the injury affects the growth plate or if the bones and cartilage in the knee area are so damaged that the healing is quite improper. This is a very real risk, especially for the children, as their bones are still developing.
Underlying Medical Conditions: Bone or joint diseases such as osteoarthritis, rheumatoid arthritis, or metabolic bone disorders put one at a greater risk of knock-knees, especially if it is in adulthood that the conditions occur.
Age: Knock-knees in children is one of the natural developmental stages. But when it comes to adults, ageing is one of the contributors to the gradual deterioration of the joints, leading to knock-knees, especially if there is at least one joint problem beforehand.
Improper Footwear or Gait Issues: Long-term negative effects on knee alignment can be caused by poor posture, improper gait or the use of footwear with little or no support, and then the situation may be quite serious knock-knees.
