About the condition
A lateral ankle sprain injures ligaments on the outside of the ankle. Fractures, tendon injuries and syndesmosis injuries can present differently and need a different plan.
Treatment options
Early assessment establishes the likely injury and whether imaging or referral is needed. External support and progressive weight-bearing may be appropriate according to severity.
Surgical considerations
Most lateral sprains are managed without surgery. A complex injury or persistent instability may need specialist assessment.
Rehabilitation principles
Rehabilitation can include movement, strength and balance work. Progress from daily activity to the movements your sport or work requires rather than stopping once normal walking is possible.
Recovery expectations
Before sport, consider pain, ankle function, confidence, balance and sport performance, including the ability to complete training. These domains inform a decision; they are not a guarantee against recurrence.
Evidence context
The ankle sprain guideline supports active rehabilitation. PAASS is a consensus framework for return-to-sport assessment, not a validated universal pass score.
