After 14 days, we’ll reevaluate. Physical therapy might then be the right fork in the road.” The physician rose from her chair with an expression of compassion as the grimacing patient hobbled out of the office.

What is meant by the metaphor in this sentence?
“Physical therapy might then be the right fork in the road.”

Physical therapy will help the patient after an injury they got while picking up a fork.
