The Red Devils captain made his return to first-team action in a goalless draw with Valarenga on Sunday after suffering a cruciate ligament injury in United’s 3-1 defeat by Basel in the Champions League group stage last year.
“It was frustrating, but obviously I knew I would be out for six months,” Vidić told United’s website.
“I tried to make the best of it, to work hard and when I come back to be the same as I was before the injury.
“This was my target and we’ll see how good a job I did in that six months. It’s hard, but it’s part of the football career.
“Any sportsman has the risk of injuries and hopefully this is the past and better days are coming for me.”
The Serbia international was pleased his knee held firm in his first pre-season game of the new season, and is confident his form will continue to improve ahead of United’s Premier League campaign.
“I felt well,” he added. “After eight months without a game it’s obvious that you have to get used to your positioning, and still fitness-wise it’s not as hopefully it will be in a few weeks, but I’m pleased.
“My knee felt well, I felt well and hopefully the next game will be better.”
Vidić has made 243 appearances for the Red Devils after moving to Old Trafford from Spartak Moscow in a £7m deal in January 2006.
