What causes knee scars?

The

tissue of knee scar develops due to traumatic knee damage or as a complication of knee surgery. It can form in procedures such as the surgery of the anterior cross ligament (ACL) or complete knee replacement. Like other types of scar tissue, the tissue of the scar in the knee is a bundle of collagen fibers that develop during the wound repair. The formation of scar tissue is often problematic due to its connection with the stiffness of the knees. During the healing process, some individuals develop a condition known as arthrofibrosis in which excessive internal scar is formed, causing the ligaments to surround the joint cavity and limit or fully prevent knee bending.

The formation of excess knee scar tissue depends on the severity of trauma and genetic factors. In arthrofibrosis, open spaces inside the joint are filled with solid fiber tissue and the patient experiences lack of movement or "frozen" joint. Lack of mobility in The knee further deteriorates the problem and results in the formation of stiffer scars tissue than wouldOtherwise, it was present, which further reduces movement.

In cases where excessive joint stiffness is observed due to knee scar tissue, further surgical intervention may be required to return the knee to an acceptable range of movement. The patient is expected to be able to bend his knee at least 90 degrees. If this is not the case, and if physical therapy failed to bring the desired results, the patient could be returned to the hospital to undergo a process in which the knee is forcibly bent to break the scars and restore movement. This procedure is usually performed under general anesthesia and is known as manipulation in anesthesia (MUA). After the scars tissue was interrupted by MUA, the patient must undergo multilazical therapy.

While this intervention is sometimes necessary, orthopedic surgeons and practicing sports medicine usually recommend, if possible, to perform conservative treatment. UseMachines of continuous passive movement (CPM) are prescribed after knee surgery to prevent the formation of stiffness and scars in the knee. CPM works by gently bending the knee in a row of repetition, expanding the range of knee movement without the need for physical exertion that could damage the knee. Physical therapy and deep tissue massage are also popular therapeutic methods used to improve flexibility and disgrace the tissue of the knee scar.
