Symptoms of Knock Knees

If you or your child has knock knees then you’re probably wondering how serious of a problem it is. Whether or not you need knock knee correction will depend on various factors like what symptoms you have. Symptoms of knock knees will vary from person to person.

A person is considered knocked kneed when their knees point inward and touch, but their ankles don’t. This is part of the normal growth and development of young children while they learn to start standing, walking, and running by themselves.

Knock knees on a child will become more obvious by the time the child turns 3 years old. However, as the child gets older this leg deformity will become less pronounced.

This angular deformity usually causes both knees of the child to turn inward and touch, but there are some instances where only one knee will knock and the other will stay straight.

TheĀ child’s knock knees should correct themselves by the time they turn 8 years old (5 to 9 degrees). There is a good chance there’s an underlying condition causing the problem if the knocking of the knees doesn’t self correct by this age.

Symptoms of Knock Knees

Symptoms of Knock Knees

Symptoms of knock knees are usually very noticeable, even in people with just slight/mild knock knees. Some of the most common symptoms of this leg deformity include:

  • Abnormal walking gait
  • Knees are constantly touching/rubbing against each other, but ankles don’t
  • The distance between the ankles when standing straight up is more than 3 inches (8cm)
  • Knee turns inward excessively
  • Unequal knee angles
  • Knock knees at an angle more than 15 degrees
  • Problems with walking
  • A limp
  • Pain in the knee
  • Arthritis symptoms
  • Knees that touch
  • Inwardly curved legs
  • Feet too far apart


If you experience any of these knock knee symptoms then consulting with a doctor should be your next step. A qualified doctor will be able to let you know for sure if you have knock knees or not. Not only determiningĀ if you’re knock kneed, but also letting you know how severe the problem is if you are.

The doctor will make this determination by examining your legs and asking questions about any walking problems or pain in the knee you have. Besides taking a look at your legs the doctor will most likely take some measurements in order to see if the distance between your ankles is greater than 8 cm while standing.

Sometimes the doctor may refer you to a bone and joint specialist to get an X-ray examination of your legs done to make sure the cause of your knock knees isn’t due to a fracture or bone disease. In some cases blood tests will be done also in order to check for underlying conditions causing the leg deformity.

Always remember that a slight degree of knock knee is okay and shouldn’t cause any problems. However, if an adult or child has severe knock knees then getting treated with braces, orthotics, exercises, or surgery may be mandatory in order to avoid more serious complications like arthritis.

Surgical procedures do have high success rates but shouldn’t be performed unless it is the only option to correct the problem, and it must be done at the right age. Getting knock knees corrected without surgery is possible depending on the severity of the genu valgum and the age of the person.
