Knock knees, medically termed “genu valgum,” is a condition where the knees touch each other when the legs are straightened. While it’s commonly seen in children and often corrects itself as they grow, it can persist into adulthood and lead to various complications. This article delves into the problems knock knees can cause and how to manage them.
Let’s gset straight to the point.
Knock knees, or “genu valgum,” is a condition where the knees touch while the legs are straightened. It is common in young children and usually corrects itself by age 7-8, but it can persist into adulthood, causing problems like gait imbalance, arthritis, pain, and increased risk of knee injuries.
In adults, causes include injury, genetics, bone diseases, and arthritis. Treatment options vary by age and severity, ranging from observation in children to physical therapy, orthotics, or surgery in adults for more severe cases.
Consulting with healthcare professionals is crucial for appropriate treatment.
What are Knock Knees?
Knock knees is a condition characterised by an inward angulation of the lower leg in relation to the thigh. When viewed from the front, the knees appear closer together while the ankles are spread apart, creating a distinct shape that resembles the letter “V.”
Development and Prevalence
Children between the ages of three and five years old are the ones who most frequently exhibit knock knees. It is a normal stage in the progression of a child’s growth, and in the vast majority of cases, the child’s legs eventually straighten out as they get older, usually by the age of 7 or 8. However, it is important to remember that the intensity of knock knees and how long they last might differ from one person to the next.
Causes in Children
In children, bowed legs or knock knees are frequently a component of the normal alignment of the legs that occurs as the kid grows. Although the precise reason isn’t always clear, it’s generally accepted that a person’s genes, diet, and overall development patterns are all contributing factors.
Causes in Adults
Knock knees can develop or continue throughout adulthood, despite the fact that this is far less prevalent. Adults can have a wider variety of reasons, some of which include the following:
- Injury or Trauma: An injury to the knee joint or the growth plate can lead to knocked knees.
- Bone Diseases: Conditions like rickets, which is caused by a deficiency of vitamin D, calcium, or phosphate, can lead to bone deformities, including knock knees.
- Genetics: Some people might inherit a predisposition to develop knock knees.
- Arthritis: Particularly osteoarthritis, can change the structure and alignment of the knee, leading to knock knees.
Physical Appearance and Symptoms
In addition to the evident visual look of the knees touching or almost touching, those who have knocked knees may also walk in an awkward or pigeon-toed manner as a result of the condition. There is a possibility that some people will suffer discomfort or soreness, particularly after standing or walking for extended periods of time.
Potential Complications of Knock Knees
In the event that a knock knee is not treated or managed properly, it might result in a variety of issues. These difficulties can have an impact on a person’s quality of life as well as their mobility in general. The following is a more in-depth look at the key issues that are related to knock knees:
1. Gait Imbalance and Instability
- Description: The altered alignment of the legs can disrupt the natural biomechanics of walking. This can lead to an uneven distribution of weight, causing an imbalance in the gait.
- Consequences: This imbalance can result in increased strain on other parts of the body, such as the hips and lower back. Over time, this can lead to pain in these areas and an increased risk of falls and related injuries.
2. Arthritis
- Description: Osteoarthritis is a degenerative joint disease where the protective cartilage that cushions the ends of the bones wears down over time.
- Consequences: Knock knees can accelerate the wear and tear on the knee joint due to the uneven distribution of weight. This can lead to the early onset of osteoarthritis, characterised by pain, swelling, and reduced range of motion in the knee.
3. Meniscus Tears
- Description: The meniscus is a C-shaped piece of cartilage in the knee that acts as a cushion between the femur (thigh bone) and tibia (shin bone).
- Consequences: The altered alignment of the knee in those with knock knees can place additional stress on the meniscus. Over time, this increased stress can lead to tears, which can cause pain, swelling, and a locking sensation in the knee.
4. Knee Dislocations
- Description: A knee dislocation occurs when the bones of the knee are out of place, either partially or entirely.
- Consequences: The abnormal alignment associated with knock knees can increase the risk of dislocations. These dislocations can be extremely painful and may require immediate medical attention. Repeated dislocations can weaken the knee joint, making future dislocations more likely.
5. Pain and Discomfort
- Description: The altered biomechanics of the knee due to knock knees can lead to discomfort and pain.
- Consequences: This pain can be exacerbated by physical activities, such as walking, running, or standing for extended periods. Over time, the pain can limit an individual’s physical activities and overall mobility, impacting their quality of life.
Managing and Treating Knock Knees
The technique that is used to manage and treat knock knees is primarily contingent on the individual’s age, the severity of the ailment, as well as the underlying cause of the problem. Even though less severe instances, particularly those affecting youngsters, might not call for intensive treatment, situations that are more severe may benefit from a variety of approaches. The following is a more in-depth examination of the key therapy options:
1. Observation
- Description: Especially in children, knock knees can be a natural part of growth and development. In many cases, the condition corrects itself as the child matures.
- Procedure: Regular pediatric check-ups will involve monitoring the alignment of the child’s legs. This can be done through visual assessments and occasionally using X-rays to track the bone development.
- Benefits: This non-invasive approach allows the child’s growth to take its course without unnecessary interventions. It’s a wait-and-see method that’s effective for many children.
2. Physical Therapy
- Description: Physical therapy involves exercises and routines designed to strengthen the muscles around the knee and improve overall leg alignment.
- Procedure: A physical therapist will assess the individual’s specific needs and design a tailored exercise regimen. This might include stretches, resistance exercises, and balance training.
- Benefits: Strengthening the muscles can provide better support to the knee joint, potentially reducing pain and improving stability. It can also enhance joint mobility and overall leg function.
3. Orthotics
- Description: Orthotics are custom-made shoe inserts designed to correct foot and ankle alignment, which can indirectly influence knee alignment.
- Procedure: A podiatrist or orthopedic specialist will assess the individual’s foot structure and gait. Based on this assessment, custom orthotics will be designed to provide the necessary support and correction.
- Benefits: By correcting foot and ankle alignment, orthotics can reduce the strain on the knee caused by knocked knees. They can also improve overall comfort when walking or standing.
4. Surgery
- Description: Surgical intervention might be necessary in severe cases, especially when there’s significant pain or the risk of other complications.
- Procedure: The type of surgery will depend on the individual’s specific condition. Common procedures include guided growth surgery (for children), where small plates are used to guide the growth of the bones, and osteotomy (for adults), where the bone is cut and realigned.
- Benefits: Surgery can provide a long-term solution to correct the alignment of the knees. It can prevent further complications, reduce pain, and improve overall leg function.
It is of the utmost importance to emphasise the need to determine the most appropriate method of therapy in collaboration with licenced medical experts. They are able to offer direction depending on the unique requirements of the individual as well as the severity of the ailment.
Conclusion
Although knock knees are often not harmful in children, if they are not treated properly in adults, they can result in a variety of issues. If you are able to see the warning signals early on and obtain the proper medical guidance, you may help prevent long-term problems and ensure that your knee continues to operate normally. If you or someone you know is struggling with knock knees, it is imperative to seek the advice of a qualified medical practitioner in order to determine the most effective course of treatment.
