What Are Bow Legged Or Knocked Knees?
A malalignment of the lower extremity, including bow legged and knocked knees, can be caused by a congenital deformity or the result of a past injury or meniscus deficiency. Although many patients may display a certain level of improper alignment, not all will experience symptoms such as pain and swelling. The two types of malalignment of the lower extremity are varus and valgus.
Varus (bow legged) – This condition occurs when the majority of the body’s weight passes through the medial (inside) portion of the joint, potentially making the lateral collateral ligaments (LCLs) more susceptible to injury.
Valgus (knocked knees) – In this condition, the majority of the body’s weight passes through the lateral (outside) portion of the joint, potentially making the medial collateral ligaments (MCLs) more susceptible to injury.
Proper alignment is essential for the knee joint to be balanced and stable. A healthy and properly balanced joint transfers the body’s weight evenly through the middle of the knee joint. When the knee becomes unbalanced due to a congenital deformity, meniscus deficiency, or a past injury, it becomes overloaded and leads to injuries such as osteoarthritis, chondral defects, ligament tears, and meniscal tears.
What Are The Symptoms Of Knocked Knees Or Bowlegged Knees?
The conditions of knocked knees and bow-leggedness can typically be observed when a patient is standing or walking. Pain within and around the knee joint is the most common symptom for both malalignment conditions. If left untreated or subjected to excessive stress, the pain can become increasingly severe. Some patients may also experience inflammation, swelling, and stiffness.
