What are the deformities at the knees?
There are 2 main types of knee malalignment: Valgus Deformity – Valgus deformity (genu valgum) causes the knees to bow inward, giving a knock-kneed appearance and putting extra pressure on the outer (lateral) compartment of the knee joint.
What is Valgum?
Genu valgum, known as knock-knees, is a knee misalignment that turns your knees inward. When people with knock-knees stand up with their knees together, there’s a gap of 3 inches or more between their ankles.
What is knock kneed appearance?
Genu valgum (knock-knees) is a common lower leg abnormality that is usually seen in the toddler, preschool and early school age child. In genu valgum, the lower extremities turn inward, causing the appearance of the knees to be touching while the ankles remain apart.
What is knock-knees in children?

Can you fix varus knee?
The most common type of surgery used to treat varus knee without significant osteoarthritis, particularly in younger patients, is a high tibial osteotomy. This procedure realigns the tibia by cutting into the bone and reshaping it. This relieves the pressure on your knee caused by poor tibiofemoral alignment.
What is a valgus knee brace?
Valgus knee unloader braces are often prescribed as treatment for knee osteoarthritis (OA). These braces are designed to redistribute the loading in the knee, thereby reducing medial contact forces.
How do you tell if your child is knock kneed?
The symptoms of knock knees are visible when a child stands with their legs straight and toes pointed forward. Symptoms include: symmetric inward angulation of the knees. ankles remain apart while the knees are touching.
What is knock-knee syndrome?
Knock knee (also called “knock-knee deformity,” “knock-knee syndrome,” “knocked knee” or “genu valgum”) is an incorrect alignment around the knee that can affect people of all ages. If left untreated, it can lead to knee pain and joint degeneration.
Can you fix knock knees without surgery?
In almost all cases of genu valgum, the condition will resolve itself before a child reaches adolescence. For older children and adults, the most likely form of therapy involves stretches and exercises to realign the knees and relieve pain. Some people might find relief with orthotics or braces.

Congenital deformities of the knee include hyperextension and flexion deformities, present at birth, whose severity at first glance may appear to be incompatible with functional ambulation. With the exception of patellar dislocation, which may not be apparent at birth,…
How old does a child have to be to have knock knee?
With further normal development, knees gradually drift into valgus (knock-knee). This valgus deformity is maximal at around age 3–4 years with an average lateral tibiofemoral angle of 12 degrees [11].
What are the different types of knee defromities?
Knee defromities are common cause of concern, particularly in growing children and adolescents. These are of two types – knock knees where the knees collide with each other, and bow legs where there is a gap between the knees when one stands.
How is surgery done for a knee deformity?
Over a period of time (usually a year or two), when inner side growth stops but outer side continues to grow, the growth gets equalised, and deformity gets corrected. This is done by surgery which involves putting some implant (staples or plate) across the growing part.
