Vidic is confident that cautious approach could see him back in the reckoning full-time in time for the season's climax.
"With playing Wednesday and Saturday, some games I have to think if it's good for myself to play or not," the Serbia defender told BBC Radio Manchester.
"After every game I feel better and better, which is a good sign.
"Sometimes I will get reactions, sometimes not.
"When I have got through two or three months without injuries, I will be fine. It's not long-term. It's normal procedure after this kind of operation.
"We have to manage the knee for the next two or three months and after that it's going to be normal."
