sprained ankle how long on crutches
Jupiterimages/Creatas/Getty Images. Recovery time for ankle injuries varies based on the severity, but for a grade 2 sprain requiring crutches, it will typically take 5 to 10 weeks until the joint is fully healed. You will want to use crutches for the first 4 to 8 weeks, longer if your doctor recommends to. For a grade 3 sprain, the joint may be unusable for 3 to 6 months and perhaps longer if the injury is serious. Crutches become absolutely necessary for the entirety of the healing process for an injury of this severity.
