What describes a Grade 2 joint sprain?

A Grade 2 joint sprain is characterized by moderate pain and swelling, alongside some degree of instability in the joint. This type of sprain indicates that the ligaments have been partially torn, which explains the combination of swelling and pain, as well as the instability that can be observed during movement or palpation. In a Grade 2 sprain, the person may experience discomfort, and while the joint can still function to some extent, there will be a noticeable reduction in stability compared to a healthy joint.

The inclusion of slight instability signifies that the structural integrity of the joint has been compromised, causing a risk of further injury if not treated appropriately. This aligns well with the signs and symptoms associated with a Grade 2 sprain, making it the correct description.
