Healing Time for Conservative Treatment of Ankle Sprains
Conservative treatment for ankle sprains typically requires 3-4 weeks for mild sprains (distortions) and 6-8 weeks for more severe sprains (partial or total ligament ruptures) to heal completely. 1
Healing Timeline Based on Severity
Mild Ankle Sprains (Distortion)
- Return to light work: 2 weeks
- Full recovery: 3-4 weeks depending on task requirements 1
- Restrictions during recovery: Mostly sitting work, no lifting exceeding 10 kg, limited standing/walking on uneven surfaces
Moderate to Severe Sprains (Partial or Total Ligament Rupture)
- Return to light work: 3-6 weeks
- Full recovery: 6-8 weeks depending on task requirements and physiotherapy results 1
- Restrictions during recovery: Same as mild sprains but for longer duration
Recommended Treatment Approach
Immediate Management (0-10 days)
- Functional support preferred over immobilization 1
- A short period (<10 days) of immobilization with rigid support may help decrease pain and edema 1
- Ankle brace shows greatest effects compared to other types of functional support 1
Early to Mid Recovery (10 days-6 weeks)
- Use of functional support for 4-6 weeks is recommended 1
- Exercise therapy should be initiated early to:
- Reduce recurrence risk
- Prevent functional ankle instability
- Speed up recovery 1
Common Pitfalls to Avoid
- Prolonged immobilization: A minimum of 4 weeks in a lower leg cast results in worse outcomes compared to functional support and exercise 1
- Inadequate rehabilitation: This is a common cause of persistent pain beyond 6 weeks 2
- Neglecting exercise therapy: Exercise therapy is crucial for preventing recurrence 1
- Inappropriate support: Treatment with proper ankle support (brace/tape) is more effective than compression bandage alone 1
Special Considerations
Return to Sports
- Return to sports typically takes longer than return to daily activities
- Average time for resuming sport activity: 4.88 days (range 1.5-8.25 days) 1
- Athletes may require additional rehabilitation focused on proprioception and balance training
Persistent Pain
If pain persists beyond 6 weeks, consider these potential causes 2:
- Inadequate rehabilitation
- Impingement
- Occult osteochondral lesions
- Peroneal tendon or syndesmosis injury
- Lateral instability
Treatment Efficacy
- Manual therapy combined with exercise therapy shows better outcomes than exercise therapy alone 1, 3
- Surgical treatment generally shows longer recovery times and higher incidences of ankle stiffness compared to conservative treatment 1
Follow-up Care
- Continue with home exercise program focusing on balance and coordination to prevent recurrences, especially among athletes 1
- Exercise therapy should be included in regular training activities or performed at home 1
Remember that while most ankle sprains (80%) make a full recovery with conservative management, approximately 20% develop chronic ankle instability 4, making proper initial treatment and rehabilitation essential for optimal outcomes.
