Study Notes
Bone Characteristics and Functions
- The femur is larger and bears 60% of the weight in the right leg.
- The fibula is not part of the knee joint and serves primarily for muscle attachment and not weight-bearing.
- The femur has a large triangular-shaped bony prominence anteriorly known as the anterior inferior iliac spine.
Q-Angle Information
- Normal range for the Q-angle is between 10° to 15°.
- Average Q-angle in males is approximately 10°.
- Average Q-angle in females is approximately 15°.
- Abnormal increase in the Q-angle is associated with conditions such as patellofemoral pain syndrome.
Patella and Its Functionality
- The patellar surface on the femur has a concave groove for articulation with the patella.
- The surface of the patella that is convex and rough provides stability and allows muscle attachment.
- The subcutaneous prepatellar bursa is located between the skin and the patella to reduce friction during movement.
Patellar Features
- The larger and deeper facet of the patella is known as the medial facet.
- The quadriceps femoris tendon continues as the patellar ligament, which inserts on the tibia.
- The patella usually dislocates laterally during a patellar dislocation due to its anatomical orientation.
Tibial Features
- The tibia has flattened areas for the insertion of the iliotibial band, enhancing stability and movement.
- The medial condyle of the tibia articulates with the medial condyle of the femur.
Ossification and Development
- Several centers of ossification appear within the quadriceps femoris tendon around the age of 2-3 years.
Joint Articulation
- The patellofemoral articulation is classified as a synovial joint.
- As the knee extends, the patella glides upward along the femur, maintaining knee stability.
- During knee extension, the patella lies against the femoral groove.
Ligament Attachments
- The medial collateral ligament attaches to the medial epicondyle of the femur.
- The lateral collateral ligament attaches to the lateral epicondyle of the femur.
Additional Bone Characteristics
- The femur is more massive at the proximal end, consisting of the medial and lateral condyles.
- The non-articular area of bone between the condyles of the femur is known as the intercondylar notch.
- The largest sesamoid bone in the body is the patella, developed within a tendon.
