Name the three hamstring muscles.
a. Semitendinosus b. Semimembranosus c. Bicep Femoris
4. The___ ligaments assist in reducing valgus and varus (abduction and adduction of the tibia on femur) movement in the knee, while the___ ligaments control anterior and posterior movement of the femur on the tibia.
collateral, cruciate
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
