false

One of the characteristics of a grade 3 medial collateral ligament sprain is a definite loss of passive range of motion.

false

When performing the Apley's compression test, a medial meniscus tear can be detected by internal rotation of the tibia and a lateral meniscus tear can be detected by external rotation of the leg.

false

four

Running, jogging, and sprinting are examples of:

functional tests

Most injuries to the medial collateral ligament result from blows to the:

lateral aspect of the knee

Which of the following is a ligament that protects the knee from valgus stress and external tibial rotation?

medial collateral

A grade 3 medial collateral ligament sprain usually presents with some valgus instability at full extension and significant opening at 30 degrees of flexion.

true

A plica is a thickened fold of synovial membrane lining the inside of the joint capsule.

true

An acute patellar dislocation is often associated with the sudden twisting of the body while the foot or feet are planted.

true

An injury to the lateral collateral ligament most often occurs either as a result of a laterally directed varus force from the medial side or from medial rotation of the tibia.

true

During a varus stress test, the examiner tests the lateral collateral ligament by holding the ankle firmly with one hand while placing the other over the medial joint line.

true

Most patellar fractures are the result of indirect trauma in which a severe pull of the patellar tendon occurs against the femur when the knee is semiflexed.

true

When is the anterior cruciate ligament most often injured?

During deceleration with the knee in valgus and the tibia internally rotated

Which of the following is true of a grade 1 sprain to the medial collateral ligament?

There is point tenderness just below the medial joint line.

Which of the following is a mechanism of injury that leaves the posterior cruciate ligament at greatest risk for injury?

false

For a grade 3 medial collateral ligament sprain, the recommended treatment is surgical repair followed by vigorous rehabilitation.

false
