Joint and movement of the lower limb

In erect bipedal position, the femurs are directed

• inferolaterally

• inferomedially

• on the coronal plane

• on the sagittal plane

• on the transverse plane

The normal femoral angle of inclination of an adult is

• 105-125 degrees

• 100-105 degrees

• 105-140 degrees

• 120-135 degrees

• 135-140 degrees

The acetabular branch of the obturator artery runs along the

• iliofemoral ligament

• pubofemoral ligament

• ligamentum teres

• ischiofemoral ligament

• intertrochanter line

What are the ligaments that adjoins the hip joint?

• Iliofemoral ligament

• Pubofemoral ligament

• Ischiofemoral ligament

• Ligamentum teres

• Acetabular labrum

The femur would more likely to undergo avascular necrosis in

• Intertrochanteric fracture

• Subcapital fracture

Which of the following regarding the menisci is incorrect?

• They absorb 1/3rd of knee impact load.

• They heal poorly because most areas are avascular.

• Tibial collateral ligament is firmly attached to the medial meniscus.

• Fibular collateral ligament is firmly attached to the lateral meniscus.

• Medial menisci are C shaped.

Which of the following about locking of knee joint is correct?

• The articular surface of fibular femoral condyle is longer than the articular surface on tibial femoral condyle.

• The femur slightly laterally rotates on the tibia to lock the knee joint in place.

• Locking of the knee reduces contact surface area between articular surfaces of femoral and tibial condyles.

• The key to lock the knee joint is popliteus muscle.

• The anterior cruciate ligament and collateral ligaments are taut when the knee joint is fully extended.

Tearing is more common on

• ACL

• PCL

• PCCW

• LCL

• MCL

Which of the following about the ACL is correct?

• It is slackened when the knee is extended.

• It prevents hyperflexion of the knee joint.

• Most ACL tears are a result of tendinitis.

• If the tibia can be pulled anteriorly over a secured femur, then the ACL is intact.

• It prevents the tibia from sliding anteriorly in front of the femur.

What would most likely be the condition of his right knee?

• prepatellar bursitis

• infrapatellar bursitis

• Pott’s fracture

• clergyman’s knee

• PCL injury
