When a person first experiences a knee problem, it may be difficult to work out what is wrong or whether or not the symptoms are serious enough to warrant an appointment with the doctor.
Knee arthrofibrosis is a complication in which an excessive amount of scar tissue forms that limits the knee's normal amount of flexion (how far the knee bends) and extension (how far the knee straightens). This problem occurs when the body's normal healing process after an injury or operation is greatly exaggerated and an excessive amount of scar tissue is produced. If untreated, arthrofibrosis eventually causes permanent dysfunction of the limb and severe arthritis.
There are many conditions or factors that may cause arthrofibrosis. These include a serious injury to the knee (fracture or dislocation), an infection, an operation that has been done incorrectly, poor or non-existent physical therapy, and so on. Arthrofibrosis triggered by these conditions or problems is referred to as secondary arthrofibrosis because the scarring is a local problem that occurred from a specific cause and is not part of a generalized healing disorder. The vast majority of patients treated for arthrofibrosis are in this category. However, in rare cases, arthrofibrosis occurs without an inciting event in patients who have a general problem with scar tissue biology, and who tend to normally produce excessive scar tissue in response to any injury or surgery anywhere in the body. This problem is referred to as primary arthrofibrosis.
