1. Where does the patellar ligament attach distally?
Intercondylar eminence of the tibia
Head of the fibula
Medial femoral epicondyle
Tibial tuberosity
2. Which movement is the anterior cruciate ligament primarily positioned to resist?
Posterior translation of the tibia relative to the femur
Compression of the menisci during weight bearing
Upward movement of the patella during extension
Anterior translation of the tibia relative to the femur
3. Which surfaces form the main weight-bearing tibiofemoral articulations?
The femoral epicondyles and fibular head
The patellar facets and tibial tuberosity
The femoral condyles and corresponding tibial plateaus
The intercondylar notch and patellar apex
4. A posterior knee dislocation raises concern for a vessel that runs through the popliteal fossa close to the joint. Which vessel is it?
Anterior tibial artery
Great saphenous vein
Medial circumflex femoral artery
Popliteal artery
5. What type of bone is the patella?
A short bone forming the lateral side of the knee joint
A sesamoid bone embedded within the quadriceps tendon mechanism
A flat bone attached directly to the tibial plateau
An irregular bone located behind the femoral condyles
6. During a posterior drawer test, the tibia moves backward relative to the femur. Which ligament normally limits this movement?
Anterior cruciate ligament
Medial patellofemoral ligament
Posterior cruciate ligament
Transverse ligament of the knee
7. During the final phase of weight-bearing knee extension, the tibia is fixed. Which motion contributes to the screw-home mechanism?
Medial rotation of the femur on the tibia
Lateral rotation of the femur on the tibia
Anterior rotation of the patella on the tibia
Medial rotation of the fibula on the femur
8. Which three tendons form the pes anserinus on the anteromedial proximal tibia?
Rectus femoris, vastus medialis, and vastus lateralis
Biceps femoris, popliteus, and plantaris
Sartorius, gracilis, and semitendinosus
Semimembranosus, gastrocnemius, and soleus
9. A structure located deep to the patellar ligament and anterior to the knee joint capsule is irritated. Which structure best matches that location?
Medial meniscus
Infrapatellar fat pad
Popliteus tendon
Semimembranosus bursa
10. A clinician palpates the fibular head to locate the distal attachment of which knee ligament?
Medial collateral ligament
Lateral collateral ligament
Posterior cruciate ligament
Oblique popliteal ligament
11. A seated person straightens the knee from a flexed position against resistance. Which muscle group is producing the primary movement?
Quadriceps femoris
Hip adductors
Gastrocnemius–soleus complex
Hamstrings
12. During arthroscopy, a crescent-shaped fibrocartilage is seen firmly connected to the deep fibers of the medial collateral ligament. Which structure is it?
Medial meniscus
Infrapatellar fat pad
Articular cartilage of the patella
Lateral meniscus
13. Which structural classification best describes the tibiofemoral joint?
A synovial modified hinge joint
A fibrous syndesmosis
A synovial ball-and-socket joint
A cartilaginous symphysis
14. A valgus force pushes the knee inward and opens the medial side of the joint. Which ligament is placed under the greatest direct tension?
Anterior cruciate ligament
Lateral collateral ligament
Patellar ligament
Medial collateral ligament
15. Imaging shows fluid collecting immediately superior to the patella, deep to the quadriceps tendon. Which space is being described?
Prepatellar bursa
Superficial infrapatellar bursa
Suprapatellar bursa or recess
Pes anserine bursa
16. With the foot free to move, which action of the popliteus helps initiate knee flexion from a fully extended position?
External rotation of the tibia on the femur
Internal rotation of the tibia on the femur
Lateral displacement of the patella
Anterior translation of the femur on the tibia
