Note the associated anterior cruciate tear (black arrow). The deep MCL (dMCL) is a thickening of the medial joint capsule. The lateral collateral ligament (LCL) complex resists excessive varus and external rotational stress. A doctor can often distinguish between tendinosis (degenerated tendons) and tendonitis (inflamed tendons) by scanning the affected area using an ultrasound or magnetic resonance imaging (MRI) scan.

Anterior cruciate ligament (ACL) mucoid degeneration, along with tears and anterior cruciate ligament ganglion cysts, is a relatively common cause of increased signal within the anterior cruciate ligament (ACL ). This causes the ligament to lose its normal stretch and elasticity similar to a worn-out rubber band. Common symptoms of tendinosis are: A person who has tendinitis can expect a faster recovery time of up to 6 weeks. The medial collateral ligament (MCL) is a wide, thick band of tissue that runs down the inner part of the knee from the thighbone (femur) to a point on the shinbone (tibia) about 4 to 6 inches from the knee.
