Chondromalacia

deterioration of the cartilage

The non-weight bearing bone of the lower leg is the

fibula

The four muscles that comprise the quadriceps group are the

rectu femoris, vastus intermidus, vastus medialis, vastus lateralis

The main weight bearing bone of the lower leg is the

tibia

Osgood-schatter

Tibial Tuberosity

What criteria would be used to determine when the athlete is ready to return to sports participation?

A specific knee rehabilitation program.

Meniscus Tear

Buckle Handle

Are the quadriceps more likely to be contused or strained? Why?

Contused because you mostly hit in the anterior part of the knee.

How does a torsion injury occur to the knee joint?

Feet are fixed and the body/injured joint is twisted

4. Describe the Osgood-Schlatter condition. Why is it common to adolescents?

Growth spurts. The knees swell.

Bursitis

Housemaid's knee (Pre-patella) Carpet layer's knee (Infer patella)

Patella Tendonitis

Jumpers Knee

Secondary Stabilizers

Meniscus and muscles

____condition is an apophysitis related to the growth center at the tibial tubercle.

Osgood-Schlatter

Are the hamstrings more likely to be contused or strain? Why?

Strain because it is not as strong and it is undeveloped

Primary Stabilizers

ligaments

Patella

runs down from the rectus femoris attaches to the tibial tuberosity is a sesmoid joing (floats)

While the knee is the largest joint the body, structurally it is very

weak
