Anterior interval arthrofibrosis is the condition of abnormal scarring in the 'anterior interval' - the space below the kneecap and behind the patellar tendon.

anterior interval

A normal anterior interval allows free movement of the fat pad, meniscus and patellar tendon.

anterior interval arthrofibrosis

Arthrofibrosis may 'gum' down mobile tissues, including the anterior interval, with adhesions, with consequent reduced range of motion of the knee.

 

Anterior interval release

To release the scar tissue the surgeon can enter the joint from the suprapatellar area above the kneecap, passing the instrument down under the intermeniscal ligament and into the area behind the patellar tendon.
