I have to disagree with you on this. Recovery from microfracture is an individual process, and what you should and shouldn't do depends completely on where the lesion is and its size. I personally know people who have made excellent, uncomplicated recoveries from microfracture who were weightbearing from day one, but that's because their lesions were in NWB areas. For weightbearing areas, 6 - 8 weeks is normal and the majority of patients recover in this time. A year NWB is really excessive, and runs the risk of introducing severe complications due to muscle atrophy and even loss of bone density due to lack of use. Be very careful recommending something this extreme to other people; your case is at odds with typical recovery times, and what may have been right for you may not be right for everyone.
The thing to do after microfracture surgery is to get a detailed rehab protocol from your surgeon, and make sure you're working with a PT who understands the nature of microfracture and is prepared to follow the surgeon's protocol. If things aren't working, go back to your surgeon or seek a second opinion if you don't feel that their advice is sound. Beyond that, I really don't think you can give generalized advice.
