Inquiry about knee varus deformity (bow-leggedness)?


Hello Dr.
Lee, thank you for taking the time to review my situation.
When I forcefully bring my legs together, only my ankles can touch, while there is a noticeable gap from my thighs through my knees to my calves.
Although I have a relatively slim physique (160 cm / 46 kg), there is still a 4 cm gap measured at the innermost part of my knees.
When I walk relaxed, my feet tend to turn slightly outward.
Additionally, when lying flat to sleep, my legs noticeably turn outward, leading to an uncomfortable sensation of my hip joints being pulled outward.
The information I found suggests treatments such as leg binding, strengthening exercises, or surgery.
I hope to improve this condition through exercise (such as physical therapy) and have prepared resistance bands for assistance, but I'm not very clear on which exercises would be most suitable.
I would like to ask for your advice.
Thank you.

For exercises related to knee varus (bowleg) deformity, please consult with the rehabilitation department, as they specialize in exercise therapy more than the orthopedic department.
Thank you.

Understanding O-legs, or genu varum, is essential for addressing knee issues effectively. This condition is characterized by a noticeable gap between the knees when the ankles are together, often leading to discomfort and potential complications in the knee and hip joints. Your description of having a 4 cm gap between your knees and experiencing discomfort in the hip joints suggests that your alignment may be contributing to your symptoms.


Treatment and Exercises for O-legs
1. Physical Therapy: Engaging in a structured physical therapy program is one of the most effective ways to address the issues associated with O-legs. A physical therapist can assess your specific condition and tailor a program that focuses on strengthening the muscles around the knees and hips, improving flexibility, and correcting alignment.

2. Strengthening Exercises:
- Quadriceps Strengthening: Exercises such as straight leg raises, squats, and wall sits can help strengthen the quadriceps, which play a crucial role in stabilizing the knee joint.

- Hip Abductor Strengthening: Strengthening the hip abductors can help improve alignment. Exercises like side leg raises, clamshells, and lateral band walks using resistance bands can be beneficial.

- Core Strengthening: A strong core supports overall body alignment. Planks, bridges, and abdominal exercises can enhance core stability, which is essential for proper leg alignment.

3. Flexibility Exercises: Incorporating stretching into your routine can help alleviate tightness in the hip flexors and hamstrings, which can contribute to poor alignment. Focus on stretches for the hip flexors, quadriceps, hamstrings, and calves.

4. Balance and Stability Training: Exercises that improve balance and proprioception can help with overall stability. Activities like single-leg stands, balance board exercises, or yoga can enhance your body awareness and control.

5. Footwear and Orthotics: Proper footwear can significantly impact your alignment. Shoes that provide adequate support and cushioning are essential. In some cases, custom orthotics may be recommended to correct any underlying foot mechanics that contribute to O-legs.

6. Avoid High-Impact Activities: While you may be eager to engage in various physical activities, it's crucial to avoid high-impact exercises that could exacerbate your knee issues. Activities like running or jumping may place additional stress on your knees and hips.


Surgical Options
If conservative treatments do not yield satisfactory results, surgical options may be considered. These can include osteotomy, where the bone is cut and realigned to correct the angle of the knee, or other procedures to address any underlying structural issues. However, surgery is typically considered a last resort after exhausting non-invasive treatments.


Conclusion
It's commendable that you are seeking to improve your condition through exercise and physical therapy. With dedication and the right approach, many individuals with O-legs can achieve significant improvements in their symptoms and overall function. Remember to consult with a healthcare professional or physical therapist before starting any new exercise regimen to ensure that the exercises are appropriate for your specific condition. They can provide guidance on proper form and progression to maximize your results while minimizing the risk of injury.
