Adhesions are frond-like filaments which form in the knee in response to inflammation and/or prolonged immobilisation of the knee.
Adhesions limiting range of motion
The sticky strands pull adjacent soft tissues together, binding the surfaces and limiting movement.
Initially they are easily broken with therapeutic knee movement - such as patellar mobilisations and manipulation under anaesthesia - but later the adhesion tissue matures into scar-bands and these thicken and make the knee stiff. When the knee is stiffened by adhesions the condition is called arthrofibrosis.
