Frog legs


I am a junior high school student.
Today during my health check-up, it was mentioned that I have "frog legs." I would like to ask if surgery is necessary for this condition.
Besides surgery, what other treatment options are available? My legs appear long and straight, so why did the doctor say I have frog legs? Thank you for your help.
I look forward to your email.

Hello Jack: The formal medical term for frog legs is gluteal muscle spasm.
Due to tightness in the gluteal muscles, individuals are unable to bring their legs together while squatting.
In severe cases, they may need to spread their legs apart to sit down.
If it affects the squatting position, early surgical intervention is advisable.

More Info


"Frog legs" is a colloquial term often used to describe a condition known as genu valgum, or "knock knees," where the knees angle inwards and touch each other while the ankles remain apart. This condition can be particularly noticeable in children and adolescents, and it can lead to various issues, including knee pain, instability, and potential long-term joint problems if not addressed appropriately.

To determine whether surgery is necessary, several factors need to be considered:
1. Severity of the Condition: If the angle of your knees is significantly deviated (often assessed through clinical examination and X-rays), and if it is causing pain or functional limitations, surgical intervention may be recommended. However, if the condition is mild and not causing any discomfort, non-surgical treatments may be sufficient.

2. Age and Growth: Since you are still in your teenage years, your bones are likely still growing. Many children and adolescents experience some degree of genu valgum that corrects itself as they grow. Therefore, doctors often monitor the condition over time before deciding on surgical options.

3. Non-Surgical Treatments: Before considering surgery, there are several non-surgical approaches that can be effective:
- Physical Therapy: A physical therapist can design a program to strengthen the muscles around the knee, improve flexibility, and enhance overall leg alignment. This can help alleviate any discomfort and improve function.

- Bracing: In some cases, a brace may be recommended to help align the knees properly during growth.

- Weight Management: Maintaining a healthy weight can reduce stress on the knees and improve overall joint health.

4. Surgical Options: If surgery is deemed necessary, there are a few options available:
- Osteotomy: This is a surgical procedure where the bone is cut and realigned to correct the angle of the knee. This can help redistribute weight and reduce pain.

- Realignment Procedures: In some cases, the alignment of the knee joint may be adjusted to improve function and reduce pain.

5. Consultation with an Orthopedic Specialist: It is crucial to have a thorough evaluation by an orthopedic specialist who can assess your specific condition and recommend the best course of action. They may perform imaging studies, such as X-rays, to evaluate the alignment of your knees and determine the best treatment plan.

In summary, whether or not you need surgery for "frog legs" depends on the severity of the condition, your age, and whether it is causing pain or functional limitations. Non-surgical treatments are often effective, especially in younger individuals, and surgery is typically considered only when conservative measures fail or if the condition is severe. It is essential to consult with a healthcare professional who can provide personalized advice based on your specific situation.
