The city of Wichita approved the officer's medical retirement on Wednesday, according to the post.
"Although he is sad to officially leave the job he loved because of the terrible actions of a criminal, he knows his sacrifice is appreciated by all of us," the post says.
Arterburn will continue to be involved with the Wichita Police Department and the community "in other ways that will most likely be bigger and better."
Before then, Arterburn has another surgery on his leg planned.
The injured officer returned to Wichita in November; about 100 officers welcomed him home from a Texas rehabilitation hospital. He had underwent multiple surgeries and extensive rehabilitation after the crash left him unable to breathe or walk on his own.
His family is now suing the car dealership that owned the SUV that ran him over during a police chase last year. According to the lawsuit, Eddy's Chevorlet Cadillac was negligent when it failed to tell police the SUV was missing until the day Arterburn was hit.
