7. Introduction (Ankle Joint)
 Also known as talocrural joint.
 Consists of the trochlear surface of the talus and the distal
ends of the tibia and fibula.
 The talar trochlear is wider anteriorly, and so plantarflexion
is more free than dorsiflexion.
 Average values being 30-50 deg and 20-30 deg respectively.
 Strengthen by variety of ligaments, the collaterals being
the most important from the point of view of injury.
 Triangular shape medial collateral ligament (deltoid ligament) is
divided into anterior and posterior tibiotalar bands.
 Lateral collateral ligament is divided into 3 separate components
and is weaker than the medial collateral ligament.
 Anterior talofibular ligament (ATF)
 Posterior talofibular ligament (PTF)
 Calcaneofibular ligament

8. Role of the Collateral Ligaments in Ankle
Stability
Movement Controlled by
Abduction of Talus Tibiocalcaneal and tibionavicular bands
Adduction of Talus Calcaneofibular ligament
Plantarflexion ATF ligament and anterior tibiotalar band
Dorsiflexion Posterior tibiotalar band and PTF ligament
External rotation of Talus Anterior tibiotalar and tibionavicular bands
Internal rotation of Talus As above with ATF ligament

9. Introduction (Plantar Fascia)
 Thickest Fascia in the body.
 Attaches from a point just behind the medial
tubercle of calcaneus and runs anteriorly as 5
slips.
 As slips approach the metatarsal heads, they split into
superficial and deep layers.
 Superficial layer attaches to superficial fascia beneath the
skin
 Deep layer divides into medial and lateral portions to allow
passage of flexor tendons.
 Each of the 5 portions attaches to the base of proximal
phalanx and to the deep transverse ligament.
 As the foot dorsiflex and toes extend, fascia is
tighten and longitudinal arch elevated.

10. Foot Alignment
 Pronated Foot
 When the arch collapses too much and the foot
rolls inward excessively, distributing weight
unevenly.
 One of the most common foot misalignments.
 Supinated Foot
 When the foot leans to the outside.
 Weight is distributed along the outside.
 Also known as under pronation.
 Over supination reduces the body's natural shock
absorbing capability.
 Neutral Foot
 Foot and ankle maintain a straight line.
 Weight is distributed evenly across the foot and
heel.

11. Common Sports Injury Involving the Ankle
Joint
 Ankle Sprain
 Plantar Fasciitis
 Metatarsalgia
 Morton’s Neuroma
