Knee 1 Flashcards
What are the primary functions of the knee?
Support body weight, locomotion
What type of joint is the Tibiofemoral Joint?
Synovial modified hinge
List the two degrees of movement of the knee.
- Flexion/Extension (Sagittal plane)
- Medial and Lateral Rotation (Transverse plane)
What are the key bony landmarks of the distal femur?
- Anterior: Adductor tubercle, Medial and Lateral Epicondyles, Lateral buttress wall, Patellar surface
- Posterior: Linea Aspera, Medial and lateral supracondylar lines, Medial and lateral condyles, Popliteal surface, Intercondylar fossa
What is the shape and position of the Medial Meniscus?
C-shaped, narrower and thinner, less mobile
What is the role of the menisci in the knee joint?
- Enhance tibiofemoral joint stability
- Act as shock absorbers
- Conform to changing shape of femoral condyles during knee movement
True or False: The lateral meniscus is more mobile than the medial meniscus.
True
What is Patellofemoral pain (PFP)?
Pain around or behind the patella aggravated by activities that load the patellofemoral joint
What type of joint is the Patellofemoral Joint?
Synovial Saddle joint
What are the main ligaments of the knee joint?
- Lateral Collateral Ligament (Fibular)
- Medial Collateral Ligament (Tibial)
- Anterior Cruciate Ligament
- Posterior Cruciate Ligament
Fill in the blank: The proximal attachment of the Lateral Collateral Ligament is the _______.
lateral femoral epicondyle
What does the Anterior Cruciate Ligament limit?
Anterior translation of the tibia on the femur
What is the anatomical significance of the Infrapatellar Fat Pad?
Define Q Angle.
Angle between the Quadriceps muscles (particularly RF) and the Patellar tendon
What is the effect of knee locking when standing?
Reduces the amount of muscle work needed to maintain the standing position
