Quadricepstendinitis is the term used to describe inflammation of the quadriceps tendon.
Quadricepstendinitis usually occurs as a result of overdoing an activity and placing too much stress on the quadriceps tendon before it is strong enough to handle the stress.
Quadricepstendinitis may be prevented by easing into jumping or running sports and by using good training techniques.
The function of the quadriceps is primarily that of tibial (knee) extension.
Rupture of the quadriceps tendon after surgery may be associated with the procedure to harvest the graft used to reconstruct the cruciate ligaments or aggressive release of soft tissues in the case of lateral release and total knee replacement.
Quadricepsmuscle hernia: A soft mobile mass, which may be tender, is palpated anteriorly with contraction of the quadriceps.
