Angle made by the rectus femoris and the patellar tendon as they attach to the tibial tubercle.
What is the Q angle?
The ligament with the highest probability to be damaged if a blow is delivered directly to the posterior lower leg, such as clipping in football.
What is the anterior cruciate ligament (ACL)?
Injury caused by quick cutting motion that generates a great deal of abnormal force within the knee.
What is patellar dislocation/subluxation?
The smaller of the two bones in the lower leg. It gives the calf its structure and forms the top of the ankle.
What is the fibula?
Muscles that act as a hip flexor and a knee extensor. Consists of four individual muscles, they form the main bulk of the thigh, and collectively are one of the most powerful muscles in the body. Located in the anterior compartment of the thigh.
What are the vastus lateralis, vastus medialis, rectus femoris, and vastus intermedius?
Abnormal softening of cartilage, typically noted between the patella and femur.
What is chondromalacia?
The patella often dislocates in this direction.
What is laterally?
An irritation (tendinitis) of the patellar tendon complex between its attachments on the tibia and the patella.
What is jumper's knee (patellar tendinitis)?
A large broad protrusion located on the anterior surface of the proximal tibia. It can easily be palpated as the protrusion located just inferior to the patella.
What is the tibial tuberosity?
Three muscles at the back of the thigh beginning at the pelvis and running posteriorly along the length of the femur. They function to extend the thigh, rotate the leg, and bend the knee. These 3 muscles are labeled as the hamstrings.
