Arthrofibrosis is defined as a complication of injury or trauma where an excessive scar tissue response leads to painful restriction of joint motion, with scar tissue forming within the joint and surrounding soft tissue spaces and persisting despite rehabilitation exercises and stretches. The knee condition can range from tiny amounts of scar tissue to a significant amount of scarring, all limiting the joint’s range of motion and function. In 2007, the doctor ordered a follow-up MRI which showed a “little scar tissue” so a second surgery was scheduled. First, a lack of an ability to straighten ones knee out is a flexion contracture. These adhesions have not been biomechanically characterized. Arthrofibrosis can make for a challenging situation after surgery. Knee arthrofibrosis is a condition that causes limited joint range of motion due to scar tissue formation following a knee injury, a previous surgery or prolonged symptoms of osteoarthritis. Scarring and adhesions lead to loss of capsular compliance and pain. These joints can include the knee, shoulder, ankle, wrist, and hip.
