The inner ankle recovers faster than the outer ankle because of the following reasons: 1. The blood supply is richer in this part of the ankle because the thickness of the soft tissue covering the inner ankle is thicker than that of the outer ankle, and the blood supply here is better than that of the outer ankle, so if the inner and outer ankle suffer the same degree of injury, the inner ankle recovers faster. 2. 3. Since the inner ankle is more inward, the probability of injury is smaller, so if the same ankle joint suffers the same injury, it is possible that the outer ankle is injured first and then the inner ankle is injured, resulting in a faster recovery of the inner ankle. Of course, the above is only a theoretical situation, and the recovery time of the ankle joint depends on the injury mechanism and the patient’s own condition.
