Knee effusion, informally known as water on the knee, occurs when excess synovial fluid accumulates in or around the knee joint. It has many common causes, including arthritis , injury to the ligaments or meniscus , or fluid collecting in the bursa , a condition known as prepatellar bursitis .
Episodes of swelling last several days or longer, can occur with regular or semi-regular frequency, typically one or two episodes per month. Between periods of effusion, knee swelling reduces dramatically providing largely symptomless intervals.
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.
Researchers from the University of Connecticut suggest that what may work for one runner won’t help another
Though articular cartilage damage is not life-threatening, it does strongly affect one's quality of life. Articular cartilage damage is often the cause of severe pain, knee swelling, substantial reduction in mobility and severe restrictions to one's activities.

Iliotibial band syndrome is one of the leading causes of lateral knee pain in runners. The iliotibial band is a thick band of fascia composing the tendon of the tensor fasciae latae muscle. It is located on the lateral aspect of the knee, extending from the outside of the pelvis, over the hip and knee, and inserting just below the knee. The ...
A prospective cohort study of 76 runners followed for one year showed that 51 percent reported an injury. Injured runners were heavier. "Over 60% of male injured runners and over 50% of female injured runners had increased their weekly running distance by >30% between consecutive weeks at least once in the 4 weeks prior to injury."
