I already had an operation
I missed this post.......
From a previous post;
It's not that big a deal. About a 45min surgery (orthoscopy) off your crutches the next day and walking, start with short walks for a day, the next double what you did the day before and so on for a week. The following week start with light extentions and progress 10% every 2 days for a week then go to more functional movements like bodyweight squats 3 days per week for a week after that start adding small loads progressing 10-15% from there on out.
But after the first week or so, you'll be back to walking normally. Also include some light hamstring work to keep the knee healthy.
