Posterior Knee Anatomy: Comprehensive Analysis of Structures and Clinical Implications
The posterior aspect of the knee represents a complex arrangement of ligaments, menisci, and bony structures crucial for joint stability and function. Understanding these posterior elements is essential for healthcare professionals in orthopedics, sports medicine, and rehabilitation.
Labeled Components
Femur
- Primary long bone of the thigh with distinctive posterior condylar surfaces
- Provides attachment points for crucial posterior knee structures
Anterior Cruciate Ligament (ACL)

- Primary restraint against anterior tibial translation
- Originates from lateral femoral condyle and inserts on tibial plateau
Posterior Cruciate Ligament (PCL)
- Strongest knee ligament and primary restraint to posterior tibial translation
- Originates from medial femoral condyle and inserts on posterior tibia
Medial Meniscus
- C-shaped fibrocartilage structure with firm peripheral attachments
- Provides shock absorption and load distribution for medial compartment
Lateral Meniscus
- More mobile circular fibrocartilage structure
- Enhances lateral compartment congruency and stability
Fibular Collateral Ligament

- Primary lateral stabilizer of the knee
- Resists varus stress and provides rotational stability
Tibial Collateral Ligament
- Primary medial stabilizer of the knee
- Provides resistance to valgus stress and rotational forces
Tibia
- Principal weight-bearing bone of lower leg
- Forms tibial plateau for femoral articulation
Fibula
- Lateral lower leg bone
- Provides attachment for lateral ligamentous structures
Functional Anatomy
Ligamentous Stability
The posterior knee structures work in concert to provide multiplanar stability. Their complex interactions prevent excessive translation and rotation while allowing normal joint motion.
Biomechanical Relationships
Cruciate Function
- ACL-PCL reciprocal function
- Four-bar linkage system
- Roll-back mechanism
Collateral Support
- Varus/valgus stability
- Rotational control
- Dynamic stabilization
Clinical Applications
Physical Examination
Understanding posterior knee anatomy is crucial for:
- Posterior drawer test
- Sag sign assessment
- Posterolateral corner evaluation
- Meniscal examination
Common Pathologies
Ligament Injuries
- PCL tears
- Posterolateral corner injuries
- Combined ligamentous injuries
- Meniscal tears
Treatment Considerations
Conservative Management
- Physical therapy protocols
- Bracing options
- Activity modification
- Rehabilitation progression
Surgical Interventions
- Ligament reconstruction techniques
- Meniscal repair approaches
- Combined procedures
- Rehabilitation protocols
Understanding the complex posterior knee anatomy is essential for accurate diagnosis, appropriate treatment selection, and optimal patient outcomes.
