The shape and alignment of your knee are unique to you, even when your knee is healthy. Although many legs are almost straight, some are naturally bow-legged (varus) or knock-kneed (valgus).
Knee alignment can also change due to the onset of arthritis. Because of these factors, it may not be ideal to make all knees straight after knee replacement surgery.
To personalize your knee replacement for your specific knee anatomy, your doctor may consider leveraging advanced technologies.
Traditional knee replacement surgery techniques using Mechanical Alignment, or MA, aims to give every patient straight “knee alignment,” regardless of the patient’s individual natural alignment prior to surgery.
Therefore, a mechanically aligned total knee replacement frequently changes the natural alignment of your knee and your leg.
