What does the term unilaterally refer to?

The term "unilaterally" refers to an action or condition that occurs on one side only. In medical and anatomical contexts, this can describe symptoms, injuries, or conditions that affect just one side of the body, as opposed to bilaterally, which would involve both sides. For instance, if someone has pain in one knee and not the other, this could be described as unilateral knee pain. Understanding such terminology is essential in sports medicine, where knowing which side of the body is affected can be crucial for diagnosis and treatment planning.
