The labrum is a ring of cartilage that lines the hip socket or acetabulum. It provides stability for the hip joint and is also responsible for distributing pressure in the hip during physical activity.
The labrum can tear for many reasons including direct trauma, femoracetabular impingment (FAI), or hip instability. Not every labrum tear causes hip pain. Learn more about the labrum in the Patient Education section.
Knee & Shoulder Conditions
The meniscus is a firm c-shaped ring of cartilage which acts as a shock absorber in the knee. Tears can create pain, clicking, locking and mechanical symptoms. Some children are born with abnormally shaped mensci, called "discoid meniscus" which can cause knee pain and swelling in childhood or adolescence.
