Patellar tendinitis, also known as jumper's knee, is an overuse injury of the tendon that straightens the knee. [1] Symptoms include pain in the front of the knee. [ 1 ] Typically the pain and tenderness is at the lower part of the kneecap , though the upper part may also be affected. [ 2 ]
Patellofemoral pain syndrome (PFPS; not to be confused with jumper's knee) is knee pain as a result of problems between the kneecap and the femur. [4] The pain is generally in the front of the knee and comes on gradually. [2] [4] Pain may worsen with sitting down with a bent knee for long periods of time, excessive use, or climbing and ...

The patella's posterior surface is covered with a layer of smooth cartilage, which the base of the femur normally glides smoothly against when the knee is ...
Patellar tendon rupture is a tear of the tendon that connects the knee cap (patella) to the tibia. [1] Often there is sudden onset of pain and walking is difficult. [1] In a complete rupture, the ability to extend that knee is decreased. [1] A pop may be felt when it occurs. [2]
The primary symptom of prepatellar bursitis is swelling of the area around the kneecap. It generally does not produce a significant amount of pain unless pressure is applied directly. [4] The area may be red , warm to the touch, or surrounded by cellulitis, particularly if infection is present, often accompanied by fever.
Symptoms may include knee pain, swelling, and redness just below the kneecap. [2] It may be complicated by patellar tendonitis. [1] Risk factors include kneeling or crawling. [4] It may also be brought on by frequent bending of the knees while standing, squatting, running, or jumping.
