  • Large rounded articular surface medially
  • Bears significant weight during stance and articulates with medial tibial plateau

Lateral Condyle

  • Slightly smaller than medial condyle
  • Articulates with lateral tibial plateau and allows rotation

Semilunar Area

  • Curved region adjacent to medial epicondyle
  • Important for attachment of posterior capsular structures

Intercondylar Fossa

  • Deep notch between condyles
  • Houses crucial ACL and PCL attachments

Functional Anatomy

Biomechanical Significance

The distal femur’s architecture enables complex knee movements while maintaining stability. Its design allows for both rolling and gliding motions during flexion and extension. This complex geometry is crucial for normal knee kinematics.

Articular Relationships

Patellofemoral Joint

  • Patellar tracking mechanism
  • Q-angle considerations
  • Pressure distribution patterns

Tibiofemoral Joint

  • Weight-bearing mechanics
  • Rotational alignment
  • Condylar roll-back phenomenon

Clinical Applications

Surgical Considerations

Understanding distal femoral anatomy is crucial for:

  • Total knee arthroplasty planning
  • Ligament reconstruction
  • Fracture fixation
  • Osteotomy procedures

Pathological Conditions

Osteoarthritis

  • Pattern of wear
  • Compartmental involvement
  • Deformity development

Trauma

  • Fracture patterns
  • Ligamentous injuries
  • Osteochondral lesions

Advanced Concepts

Vascular Supply

The distal femur receives blood supply from:

  • Genicular arterial network
  • Nutrient arteries
  • Periosteal vessels
  • Metaphyseal blood supply

Understanding these anatomical features is essential for proper diagnosis, treatment planning, and surgical intervention in knee pathologies.
