Anterior knee pain is the classic area of pain associated with injury to
the quadriceps mechanism (the quadriceps muscle, tendons, the patella, and
the insertion of the patellar tendon on the tibial tubercle) and large knee
Anterior knee pain is characteristic of patellofemoral pain syndrome (
also referred to as patellofemoral joint syndrome or chondromalacia patellae
), particularly in patients under the age of 45, and advanced osteoarthritis
involving all compartments of the knee. It may be unilateral or bilateral.
Anterior knee pain accompanied by swelling and inflammatory change
anterior to the patella is the most common presentation of acute prepatellar
Focal anterior knee pain at the inferior pole of the patella, the origin
of the patellar tendon, is characteristic of patellar tendinopathy or
jumper's knee; this disorder is seen almost exclusively in athletes.
Focal anterior knee pain at the tibial tubercle, the insertion of the
patellar tendon, is characteristic of Osgood Schlatter disease. This
epiphysitis is seen exclusively in young men and women under the age of 19
whose growth centers are still active.
Diffuse anterior knee pain accompanied by swelling and inflammatory
change is seen with inflammatory arthritis (eg, rheumatoid arthritis, gout,
and pseudogout) or septic arthritis. Although similar to the symptoms of
acute prepatellar bursitis, patients with acute inflammatory arthritis also
have impaired flexion, but prefer to keep the affected knee slightly flexed.
This position reduces intraarticular pressure and lessens pain.
