Depending upon the location of the microfracture and the size of the defect, it can take anywhere from 4 to 7 months to be able to heal to the point where patients can increase their activities and potentially initiate occasional impact activities.
Why does it take so long for knee cartilage to heal?
The lack of active blood flow is the major reason any injury to cartilage takes a long time to heal. Cartilage has no nerve innervation, and hence there is no sensation when it is injured or damaged. When there is calcification of cartilage, the chondrocytes die.
How do you know if your meniscus repair failed?
