Well, if Sasuke is injured badly, Sakura will be by his side constantly, trying to heal him. This could lead to some deep conversations between them. They might open up about their feelings, fears, and dreams. Maybe Sasuke will finally admit his feelings for Sakura in a moment of weakness while he's injured. On the other hand, if Sakura is the one more seriously injured, Sasuke will be forced to confront his feelings as he's worried about losing her. He might be more protective of her in the future.
She could develop more empathy. After being injured, she might understand what it's like to be vulnerable. So when she sees others in pain or in difficult situations, she can relate more. For example, if there's a sick animal in the story later, she'll be more likely to try and help it because she remembers how it felt to be in need of help when she was injured.
