What is Knee Malalignment?
(Bow Legged and Knocked Knees)
In a properly balanced knee, the body’s weight is evenly transferred through the middle of the joint. This allows the body’s weight to be evenly distributed across the medial (inside) and the lateral (outside) compartments of the knee. Patients affected by malalignment of the lower extremity, also know as bow legged or knocked knees, are prone to developing knee injury and pain. Dr. Jervis Yau, orthopedic knee specialist, is available to assist patients living in the Santa Barbara, Goleta, Santa Maria and Ventura, California area suffering from malalignment through conservative and surgical treatment options.
Varus (bowleg) and valgus (knock-knee) deformities are commonly caused by congenital deformity, joint injury, meniscal deficiency and osteoarthritis. Patients who have varus deformity will have the body’s weight passing primarily through the medial (inside) of the knee. Patients with valgus deformity will have the body’s weight passing primarily through the lateral (outside) of the joint. Both conditions can be worsened through overuse, obesity or injury.
What are the Symptoms of Bow Legged or Knocked Knees?
The most common symptom of varus and valgus knee malalignment is medial and lateral joint pain, respectively. The pain will intensify if the condition is left untreated or a knee injury occurs. Patients suffering from malalignment may also experience persistent joint stiffness, swelling and inflammation.
How are Bow Legged or Knocked Knees Diagnosed?
A thorough physical examination will be performed by Dr. Yau to diagnose the correct malalignment condition. He will utilize a variety of tests to check overall leg alignment. He will also examine the knee’s balance to see how weight is distributed while in a standing position. Dr. Yau may perform a series of x-rays and MRI to determine the severity of malalignment and injury. This will aid in determining the optimal treatment plan.
