Ch.14 Knee injuries

Patellar tendinitis

Inflammation of the patellar tendon; often called jumper's knee

Describe how an AT should care for a second-degree, or moderate, MCL sprain.

It should be treated with PRICES and be put into an immobilizer. Also the AT should check for an ACL or meniscus injury.

Name the four muscles of the quadriceps.

Rectus Femoris, Vastus longus, Vastus Medialis, and Vastus Intermedius.

What three muscles compose the hamstrings? What movements can the produce?

Semimembranosus, semitendinosus, and biceps Femoris. The help with flexion.

Identify the four primary ligaments that stabilize the knee.

The ACL, MCL, LCL, AND PCL.

If an injury caused the tibia to move forward on the femur, what ligament would most likely become overstretched or torn?

The anterior cruciate ligament or ACL.

Name the tree bones that compose the knee joint.

The femur, patella, and tibia.

Name the ligament that would most likely be to stretch or tear if an opponent fell on the outside of an athlete's knee and it bent inward.

The medial collateral ligament or MCL.

Hamstrings

The name given collectively to the semimembranosus, semitendinosus, and biceps Femoris muscles, which are responsible for flexing the knee and extending the hip

Osgood-Schlatter disorder

A condition characterized by an irritation or loosening of the patellar tendon at its attachment at the top anterior aspect of the tibia, usually seen in younger athletes who perform a great deal of running and jumping

Fat pad syndrome

A condition whereby the fat pad of the knee becomes trapped between the patella and the femur. Often referred to as Hoffa's syndrome

Hoffa's syndrome

A condition whereby the fat pad of the knee becomes trapped between the patella and the femur. Often referred to as fat pad syndrome

Anterior cruciate ligament (ACL)

A knee ligament damage hat keeps the tibia from moving forward on the femur

Posterior cruciate ligament (PCL)

A knee ligament that prevents the tibia from moving posteriorly on the femur

Meniscus

A piece of cartilage within a joint, especially those pieces known as the medial and lateral menisci, which lie between the femur and tibia

Meniscectomy

A surgical procedure to remove the meniscus from the knee joint

Arthroscopic surgery

A type of surgery performed on a joint using only small puncture holes to insert instruments, including a camera, to observe and fix injured structures

Medial collateral ligament (MCL)

Helps stabilize the inside or medial aspect of the knee

Lateral collateral ligament (LCL)

Helps stabilize the outside or lateral aspect of the knee

Chondromalacia

The softening or wearing away of the cartilage that lies on the back of the patella
