What is knee malalignment syndrome?
The knee is comprised of three bones: the femur (thighbone), tibia (shinbone) and patella (kneecap). It also contains cartilage, tendons and ligaments. There are two joints within the knee: the tibia-femur joint and the patella-femur joint. Knee malalignment syndrome occurs when there is poor positioning between either of these two knee joints. In knee malalignment of the patella-femur joint, the kneecap feels either unstable, or feels too tight and painful. In knee malalignment of the tibia-femur joint, abnormal knee angulation can create undue pressure on either the inner (medial) or outer (lateral) compartment of the knee. Knee malalignment can put individuals in New York at higher risk for knee problems including knee dislocation and osteoarthritis.
Tibia-femur malalignment can give the appearance of genu valgum (knock knee) or genu varus (bow-legged). Genu valgum displays when an individual is standing straight up, their knees are together, and their feet and ankles appear spread apart. Genu varus is shown when an individual is standing straight up, their knees are apart (lower legs curve outward from the knee), and their feet appear to touch. Genu valgum and genu varum can occur as a result of birth related issues, follow a traumatic accident, or can be associated with the aging process. Dr. Williams has extensive experience in diagnosing and treating knee malalignment.
