Cattermole went under the knife last month after an injury-plagued campaign, ruling him out for the final part of this term.
He is still on crutches but the surgery was successful and the target is now to be fit for the start of next season, and the midfielder is ready to work hard in his rehabilitation rather than enjoy a relaxing summer.
"It's no golf or summer holidays for me, but I'll look forward to getting back next season," Cattermole said in the Daily Mirror.
"I've got another couple of weeks on the crutches then hopefully I'll be back in full training when the lads come back for pre-season.
"My operation went well and my knee's in good condition. I was getting pain there when I was playing and it wouldn't go away so I decided to get it done."
