TherEx | Patellar Stabilization Series [Full Lecture] | Patellar Subluxation & Treatments

The video tutorial covers patellar luxation and subluxation, explaining the anatomy of the knee and the differences between luxation and subluxation. It details the grading system for luxations and discusses conservative treatments, focusing on isometric exercises for patellar stabilization. The tutorial also includes theraband resisted exercises for knee extension.

What is the primary function of the knee extensor mechanism?

• To flex the quadriceps

• To stabilize the patella

• To allow the knee to bend

• To rotate the tibia

How is a luxation different from a subluxation?

• Luxation is less severe than subluxation

• Luxation is a complete dislocation, subluxation is partial

• Luxation involves ligament tears, subluxation does not

• Luxation is a partial dislocation, while subluxation is complete

What is the most common direction for patellar luxation?

• Medial

• Lateral

• Posterior

• Anterior

In a Grade 1 luxation, what happens to the patella when released?

• It remains dislocated

• It spontaneously dislocates

• It returns to its normal position

• It requires manual force to move

Which grade of luxation is characterized by a permanently dislocated patella that cannot be manually repositioned?

• Grade 4

• Grade 1

• Grade 2

• Grade 3

What is the primary muscle targeted in conservative interventions for patellar stabilization?

• Quadriceps

• Gluteus maximus

• Hamstrings

• Calf muscles

Which exercise is a progression from the quad set and involves hip flexion?

• Sideline hip abduction

• Straight leg raise

• Theraband resisted terminal knee extension

• Prone hip extension

What is the main purpose of the theraband resisted terminal knee extension exercise?

• To strengthen the hamstrings

• To stabilize the patella

• To increase knee flexion

• To improve hip rotation

Which muscle group is primarily worked during sideline hip abduction?

• Hamstrings

• Quadriceps

• Hip abductors

• Calf muscles

What is a key component of the quad set exercise?

• Hip abduction

• Hip flexion

• Ankle dorsiflexion

• Knee flexion
