Articulating Surfaces

Question 1

Describe the Femoral Articulating Surfaces

Answer 1

• Ends of the Lateral and Medial condyles of the femur.
• Biconvex (antero- posteriorly & medio-laterally)
• Lateral condyle is shorter and wider
• Medial condyle projects further distally
• Covered in hyaline cartilage

(- Central patella trochlear surface with a larger lateral buttress wall aspect than the medial condyle.)

Question 2

Describe the articulating surface of the tibia

Answer 2

• Superior aspect of the medial and lateral tibial condyles also known as the tibial plateau
• Concave centrally but flatter in the periphery for the attachment of the menisci
• Covered in hyaline cartilage
• Condyles are separated by intercondylar eminences which allow for the attachment of the cruciate ligaments.
• Medial surface is larger antero-posteriorly to accomodate medial femoral condyle.
