About Congenital Dislocation of the Patella

It is a relatively rare condition and may be detected at birth or later on.

A child with this condition may face difficulty in walking and abnormal walking patterns.

Anatomy of the Kneecap or the Patella

The kneecap lies within the patellofemoral groove of the thighbone and in front of the knee joint. It is attached to the quadriceps tendon on the top side and to the patellar ligament on the underside.

The kneecap is the largest sesamoid bone in the body, which means it is a rounded body mass located within a tendon and attached to a joint surface.

The main purpose of a kneecap is to reduce friction, alter the direction of the muscle pull, and change the pressure levels. Thus, the kneecap helps in leg extension and protects the knee joint on the front side.

Diagnosis of Congenital Dislocation Knee

The treating orthopedic surgeon will conduct a physical examination of the child. The child with this defect may not be able to straighten the leg.

If required, X-rays, sonography, and MRI scan will help in ascertaining the extent of deformity and future course of treatment.

The diagnosis and detection can take place when the child is just a week or so old or till he or she reaches 15 years of age.

Treatment of Congenital Dislocation of the Patella

Surgery is recommended to treat this type of dislocation of the kneecap. The surgeon will realign all the organs or parts related with the knee to ensure a stable kneecap.

This type of surgery is performed as per the condition of the patient. It may involve lengthening of the muscles and tissues located on the outer thigh and on its top too.

It can involve shortening as well as straightening of the thigh bone.

Corrective action may also be taken to resolve the knock knees condition and also ensure the peroneal nerve is well in place and protected when the knee is straightened and so on. All in all, the treating orthopedist will perform a surgery to resolve the loose kneecap condition and ensure the knee performs in a normal comprehensive manner while retaining the knee strength.
