How long can you walk with a torn ankle ligament? The details are as follows: 1. Six weeks: If the stability of the joint is good when the ankle ligament is torn, it is generally recommended that the cast be fixed for about six weeks. At three months, you can abandon the crutches and walk normally. 2.
