The Ankle Joint(Talocrural Joint)
The Ankle Joint
Also known as the
Talocrural Joint
Anterior View Ankle Joint
The Ankle Joint
Also known as the
Talocrural Joint
Typical synovial joint
mediallateral
Formed by an articulation of the
- Distal Tibia
mediallateral
Formed by an articulation of the
- Distal Tibia
- Distal Fibula
mediallateral
Formed by an articulation of the
- Distal Tibia
- Distal Fibula
- Talus
mediallateral
Distal Tibia + Medial Malleolus and
Distal Fibula + Lateral Malleolus
form a deep recess or
‘mortice’
for the body of the Talus
medial
The ankle joint is the only
‘mortice’ joint
in the body
mediallateral
Ligaments of the Ankle Joint
The ankle joint is stabilised on the
Medial Collateral Ligament
The ankle joint is stabilised on the
medial side by the
Lateral Collateral Ligament
The ankle joint is stabilised on the
lateral side by the

Medial Collateral Ligament
Calcaneum
Has two parts
- Superficial layer
- Deep layer

The superficial layer is triangular in shape and has three parts

- Posterior Talofibular
Lateral Collateral Ligament
Lateral View Ankle Joint
Has three discrete parts
- Anterior Talofibular
- Calcaneofibular
- Posterior Talofibular
Both Collateral Ligaments have 3 sets of fibres running from
Tibia or Fibula to- Anterior Talus
- Posterior Talus
- Calcaneum
Medial Collateral Ligament also has fibres from
Tibia to Navicular
Summary of Collateral Ligaments
Additionally the Tibia and Fibula are held together by two very strong ligaments

Movement of the Ankle Joint
Dorsiflexion
The ankle is a hinge joint and permits movement in one plane around a single axis
Dorsiflexion is when the foot is moved
upwards away from the ground
Plantarflexion
Plantarflexion is when the foot is
moved downwards into the ground
Plantarflexion
To help you remember the
direction think of plantarflexion as
‘planting your feet’ into the ground
