Fibrosis in the Knee
Arthrofibrosis is also known as stiff knee syndrome. The condition sometimes occurs in a knee joint that has recently been injured. It can also occur after surgery on the knee, such as a knee replacement. Over time, scar tissue builds up inside the knee, causing the knee joint to shrink and tighten (source: Healthline).
