Besides, they will also evaluate the inequality of your leg length, your knee misalignment, and uneven wear on shoe soles. And sometimes, they may ask for imaging tests (like an X-ray or MRI) to confirm the cause after a detailed examination of your bone structure.

Here are treatments which are of valgus knees:

Besides, if your condition is due to any deficiency or being overweight, your doctor may prescribe you a vitamin D supplement or weight management plan to improve your primary condition.

  • Surgery

On the contrary, if your condition is severe, your pain specialist in Dallas may recommend a more drastic treatment, i.e., knee replacement surgery. This treatment is generally common in people aged 50 years and above. A surgical procedure can amend knock-knee deformity or osteoarthritis that has affected your knee joint.

However, the doctor may recommend osteotomy surgery in younger patients that involves cutting the thigh bone to realign the knee and improve the positioning. Unfortunately, it takes almost a year to recover from surgery fully. The reason is the intrusiveness of the operation, pain, and recovery period. So doctors prefer other treatments before they recommend surgery.

  • Adjustable Orthotic Insoles

Apart from this, Adjustable Orthotic Insoles are another popular treatment for this condition. It is an adaptable pad support that kicks the foot arch as you move. According to a study by Quinnipiac University, this treatment delivers up to 89% greater arch support. Hence, it is ideal to allow continual misalignment correction that is the primary source of pain in the legs, feet, hip, spine, and ankles.

This spring-like structure that resembles ligaments is naturally present in your feet. So, there are three adjustable improvements, and the price is almost one-third of the custom orthotics. Moreover, when you compare it to the gel and foam insoles, those only last for 15 days. However, orthotic insoles last for months and feature a 60-day money-back guarantee. So, considering your condition and the severity of the deformity, your doctor can be your ultimate partner in recommending the best joint pain treatment.
