Djokovic tore the medial meniscus in his right knee at the French Open earlier this month, withdrawing ahead of a scheduled quarter-final against Casper Ruud.
He underwent surgery on the injury less than three weeks ago but still travelled to SW19 on Monday and was seen out on the practice courts.
However, the Serbian will only participate if he feels he has a realistic chance of an eighth Wimbledon crown, which would equal Roger Federer's all-time record.
"I didn't come here to play a few rounds," Djokovic told BBC Sport. "You can never know 100% what is going to happen at a tournament, but I'm going to make a decision based on the feeling that I have.
"If I know I can play close to my maximum or at maximum, then I'll play. If not, then I'll give somebody else a chance to play."
Asked if his maximum meant a title push, Djokovic replied: "That's why I'm here.
"I don't plan to retire or for this to be my last Wimbledon. The injury happened at an unfortunate moment but it's part of the sport."
Having gone through a two-hour session with bandaging on his affected knee on Monday, Djokovic added his recovery is going well and said he will give himself as much time as possible to make a decision.
"It's been going well. Rehab is going in the right direction every single day, a few per cent better and better. That's what's giving me hope and encouragement," he said.
"I still have a week left, which is plenty of time. I'm going to give my best to have a clear understanding of where I am before the draw is made, and we'll take it from there.
"I'm taking things gradually. I'm not pushing myself 100% yet but I'm hoping that's going to come in the next few days."
