Ligament and Tendon Injuries

  • What it is:
    An ankle sprain occurs when the ligaments that support the ankle stretch or tear, usually due to twisting or rolling the ankle. Sprains are graded based on severity:

    • Grade I: Mild stretching of ligaments

    • Grade II: Partial ligament tear

    • Grade III: Complete ligament tear

    Causes:

    • Sudden twist or roll of the ankle

    • Sports injuries

    • Walking or running on uneven surfaces

    • Wearing unstable or unsupportive footwear

    Symptoms:

    • Pain, swelling, and bruising around the ankle

    • Difficulty bearing weight (more severe with higher grades)

    • Instability or looseness in the joint

    • Tenderness and reduced range of motion

    • Popping sensation at the time of injury (more common in Grade II–III)

  • What it is:
    Chronic ankle instability is a condition where the ankle repeatedly gives way, especially during activity or on uneven ground. It often follows repeated ankle sprains that haven’t healed properly.

    Causes:

    • Inadequately treated or recurring ankle sprains

    • Weak or stretched ligaments

    • Poor balance or coordination

    • Muscle weakness around the ankle

    Symptoms:

    • Frequent "rolling" of the ankle

    • Persistent discomfort or swelling

    • Pain or tenderness along the outer ankle

    • Feeling of instability, especially on uneven surfaces

    • Trouble with physical activity or sports

  • What it is:
    Peroneal tendonitis is inflammation of the peroneal tendons, which run along the outside of the ankle and foot. Subluxation occurs when these tendons slip out of place, often due to a tear in the supporting retinaculum.

    Causes:

    • Overuse or repetitive ankle motion

    • Ankle sprains or instability

    • Improper footwear

    • Anatomical variations in tendon structure

    Symptoms:

    • Pain and swelling along the outer ankle

    • Snapping or popping sensation behind the ankle bone

    • Instability or feeling like the tendons are shifting

    • Worsening pain with activity, especially side-to-side motion

    • Tenderness behind or below the outer ankle

  • What it is:
    PTTD is a progressive condition where the posterior tibial tendon weakens or tears, leading to collapse of the foot arch and flatfoot deformity. It’s a common cause of adult-acquired flatfoot.

    Causes:

    • Overuse or degeneration of the tendon

    • Flat feet or abnormal foot mechanics

    • Acute injury or trauma

    • Inflammatory conditions (e.g., rheumatoid arthritis)

    Symptoms:

    • Pain and swelling along the inside of the ankle or foot

    • Gradual flattening of the foot arch

    • Difficulty standing on tiptoes or walking long distances

    • Rolling in of the ankle (pronation)

    • Pain that worsens with activity

Joint and Bone Conditions

  • What it is:
    An ankle fracture is a break in one or more of the bones that make up the ankle joint—typically the tibia, fibula, or talus. Severity can range from small cracks to full breaks that affect joint stability.

    Causes:

    • Falls or direct trauma

    • Twisting injuries (e.g., while playing sports or stepping off a curb)

    • Car accidents or high-impact trauma

    • Severe ankle sprains

    Symptoms:

    • Sudden pain and swelling around the ankle

    • Bruising or deformity

    • Inability to bear weight

    • Tenderness to touch

    • Instability or visible bone displacement (in severe cases)

  • What it is:
    Ankle arthritis is the degeneration of cartilage in the ankle joint, leading to pain, stiffness, and limited mobility. It can result from wear and tear, prior injuries, or autoimmune conditions.

    Causes:

    • Osteoarthritis (age-related degeneration)

    • Post-traumatic arthritis (following fractures or sprains)

    • Rheumatoid arthritis or other inflammatory diseases

    • Repetitive stress or overuse

    Symptoms:

    • Pain with movement or weight-bearing

    • Stiffness, especially in the morning or after rest

    • Swelling around the joint

    • Grinding or catching sensation

    • Difficulty walking on uneven surfaces

  • What it is:
    OLT is a condition where cartilage and underlying bone in the talus (a bone in the ankle joint) becomes damaged, often due to trauma. It can lead to pain and joint instability if untreated.

    Causes:

    • Ankle sprains or fractures

    • Repetitive stress injuries

    • Poor blood supply to the talus

    • Untreated cartilage damage

    Symptoms:

    • Deep ankle pain, especially with weight-bearing

    • Swelling and stiffness

    • Clicking, catching, or locking of the ankle

    • Instability or feeling of “giving out”

    • Symptoms may worsen over time if untreated

  • What it is:
    A syndesmotic injury, or high ankle sprain, affects the ligaments that connect the tibia and fibula just above the ankle. It’s more severe than a typical ankle sprain and often takes longer to heal.

    Causes:

    • Twisting or rotation injuries, especially with the foot planted

    • High-impact sports (e.g., football, skiing, soccer)

    • Falls or trauma involving forced upward or outward motion of the foot

    Symptoms:

    • Pain above the ankle, often radiating up the leg

    • Difficulty walking or bearing weight

    • Swelling and bruising in the upper ankle

    • Pain with side-to-side or rotational ankle movements

    • Longer recovery time compared to standard ankle sprains

Impingement and Soft Tissue Conditions

  • What it is:
    Anterior ankle impingement occurs when soft tissue or bone at the front of the ankle joint becomes pinched, often due to repetitive motion or bone spurs. It's sometimes called "athlete’s ankle."

    Causes:

    • Repetitive ankle dorsiflexion (bending the foot upward)

    • Bone spurs from arthritis or previous injuries

    • Scar tissue buildup after sprains

    • Sports involving frequent squatting or jumping (e.g., soccer, ballet, football)

    Symptoms:

    • Pain at the front of the ankle, especially with upward movement

    • Stiffness or limited ankle motion

    • Swelling after activity

    • Clicking or catching sensation

    • Tenderness over the front of the ankle joint

  • What it is:
    Posterior ankle impingement is compression of tissue at the back of the ankle, typically during plantarflexion (pointing the foot downward). It often affects dancers, athletes, and people with an extra bone in the back of the ankle (os trigonum).

    Causes:

    • Repetitive or forceful downward ankle motion

    • Os trigonum (an accessory bone behind the ankle)

    • Previous ankle injury or instability

    • Inflammation of surrounding soft tissues

    Symptoms:

    • Pain at the back of the ankle, especially when pointing the toes

    • Swelling or tenderness behind the ankle joint

    • Pain with activities like jumping or pushing off the foot

    • Stiffness or decreased range of motion

    • Clicking or catching with movement

  • What it is:
    Sinus tarsi syndrome is inflammation or instability in the sinus tarsi, a small cavity on the outer side of the foot between the talus and calcaneus. It often develops after ankle sprains or repetitive stress.

    Causes:

    • Previous ankle sprains (especially inversion injuries)

    • Flatfoot deformity

    • Instability or ligament damage

    • Overuse or repetitive impact on uneven surfaces

    Symptoms:

    • Pain and tenderness on the outer side of the ankle/foot

    • Instability or “wobbly” feeling in the ankle

    • Swelling or deep aching in the sinus tarsi area

    • Worse pain with standing or walking on uneven terrain

    • Stiffness or reduced motion in the subtalar joint

  • What it is:
    Tarsal tunnel syndrome is compression of the posterior tibial nerve as it passes through the tarsal tunnel, located along the inner side of the ankle. It’s similar to carpal tunnel syndrome in the wrist.

    Causes:

    • Flat feet or fallen arches

    • Swelling from injury or inflammation

    • Masses or cysts compressing the nerve

    • Systemic conditions (e.g., diabetes, arthritis)

    Symptoms:

    • Tingling, burning, or numbness along the inside of the ankle and bottom of the foot

    • Sharp, shooting pains that may radiate into the arch or toes

    • Symptoms worsen with standing or walking

    • Relief when resting or elevating the foot

    • Weakness in the foot muscles (in advanced cases)
