Anterior cruciate ligament (ACL) injury 08/14/2011
Cruciate ligament injury - anterior; ACL injury; Knee injury - anterior cruciate ligament (ACL) Considerations: The knee joint is located where the end of the thigh bone (femur) meets the top of the shin bone (tibia).

Anterior knee pain 06/13/2010
Runner's knee; Patellofemoral pain; Patellar tendinitis; Tendinitis - patellar; Jumper's knee Considerations: Your kneecap (patella) sits over the front of your knee joint. As you bend or straighten your knee, the underside of the patella glides over the bones that make up the knee. Strong tendons help attach the patella to the bones and muscles that surround the knee.
