Which of the following is true of chondromalacia patella?Multiple choice question.It is often related to either abnormal movement of the patella within the femoral groove or to overuse.It is a condition common to the rapidly growing immature adolescent's knee.This condition often develops because of repeated trauma to the knee during sports activities.The most common cause of the condition is the repeated pull of the patellar tendon at the tibial tubercle on the front of the tibia.

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.

Select all that applyIdentify the true statements about Osgood-Schlatter disease.Multiple select question.It involves softening and deterioration of the articular cartilage on the posterior surface of the patella.The most commonly accepted cause of this condition is the repeated pull of the patellar tendon at the tibial tubercle on the front of the tibia.It is characterized by ongoing pain at the attachment of the patellar tendon at the tibial tubercle.This condition usually resolves when the athlete reaches the age of 30 or 35.

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