Arthrofibrosis of the knee following ligament surgery.

Arthrofibrosis of the knee is one of the most serious complications that can result from ligament surgery. Reported incidence of arthrofibrosis following anterior cruciate ligament reconstruction ranges from 4% to 35%. The loss of motion caused by arthrofibrosis can be even more disabling than the instability for which the reconstruction was performed, often requiring extensive physical therapy and/or surgical lysis of adhesions. With aggressive rehabilitation and modifications in the bracing of knees undergoing ligament reconstruction, the incidence of this complication has decreased significantly. Additionally, delaying anterior cruciate ligament reconstruction until the acute inflammatory period has resolved has also been shown to be a significant factor in the reduction of postoperative knee stiffness.
