Brief Summary:
Our primary research question is to find out whether there is a genetic component to the development of joint contractures following knee surgery, through the application of lab techniques.

Condition or disease
Joint Contracture

Detailed Description:
After total knee replacement surgery, some people develop joint stiffness, which is also called a joint contracture. Contractures cause the envelope of the knee (called the capsule) to stiffen and become rigid so the patient can no longer move their knee the way they used to. After stretching and other exercises, only a surgery can try and divide or remove the contracture. The main purpose of this research is to study the cause of the contracture and specifically if certain people are predisposed to contractures.
