Match the types of fractures of the patella with their symptoms.InstructionsDrag and drop application.Direct fractureDirect fracture drop zone empty.Indirect fractureIndirect fracture drop zone empty.Involves little bone separationInvolves tearing of the joint capsule, separation of bone fragments, and possible tearing of the quadriceps tendon

Match the causes of fractures of the patella with their descriptions.InstructionsDrag and drop application.Direct traumaDirect trauma drop zone empty.Indirect traumaIndirect trauma drop zone empty.This most often produces fragmentation with little displacement.A severe pull of the patellar tendon occurs against the femur when the knee is semiflexed and the patella is subjected to maximum stress from the quadriceps tendon and the patellar ligament. Forcible muscle contraction may then fracture the patella at its lower half.

Arrange the actions that cause acute patellar subluxation or dislocation in the correct order of occurrence. (Place the first action at the top.)InstructionsDrag and drop application.Choice 1 of 3. An athlete plants the foot, decelerates, and simultaneously cuts in an opposite direction from the weight-bearing foot. toggle buttonAn athlete plants the foot, decelerates, and simultaneously cuts in an opposite direction from the weight-bearing foot.Choice 2 of 3. The quadriceps muscle attempts to pull in a straight line and as a result pulls the patella laterally. toggle buttonThe quadriceps muscle attempts to pull in a straight line and as a result pulls the patella laterally.Choice 3 of 3. The thigh rotates internally while the lower leg rotates externally, causing a medially directed valgus force at the knee. toggle buttonThe thigh rotates internally while the lower leg rotates externally, causing a medially directed valgus force at the knee.

Match the types of joints in the human body with the descriptions of their formation that involves the femur.InstructionsDrag and drop application.The hip jointThe hip joint drop zone empty.The knee jointThe knee joint drop zone empty.The distal femoral condyles articulate with the tibia.The proximal head of the femur articulates with the acetabulum of the pelvis.

Which of the following are true of acute patellar subluxation or dislocation?Multiple select question.The athlete experiences a complete loss of knee function along with pain and swelling.This injury is more likely to occur in a male athlete than in a female because of a narrower pelvis in a male.As a rule, displacement takes place laterally, with the patella resting on the lateral condyle.A first-time patellar dislocation is seldom associated with a fracture.

Explain at least 2-3 different types of fractures with a specific example for each fracture type. Be as detailed as possible.
