Hi Jeremy,
I think "picking" and microfracture can be interchanged. They used to "drill", but nowadays they have a tool that basically "taps" a hole into the bone.
Post surgical protocols often depend on the surgeon and what he/she feels works the best. I know that if you have the MFX done on the weight bearing surfaces of the condyles or tibial plateau, people are usually on crutches for anywhere from 4-8 weeks. I've recently had MFX done on my tochlear groove and was allowed weight bearing from day one, but in an immobilizer brace (no weight bearing bending of the knee) for 6 weeks. It's generally accepted that the first 8 weeks are critical for smooth development of the "clot" or fibrocartilage scar.
If you are uncomfortable with your rehab protocol, ask your doctor! They may have a perfectly good explanation for their protocols.
Good luck,
marjan
