Whats recovery time for knee arthroscopic surgery ?

6 weeks: But it also depends on what they did.

4-8 weeks: For straightforward partial menisectomy (removing part of meniscus) it is typically a quick recovery. Generally crutches are given for comfort but you can be weightbearing as tolerated. Once swelling and pain are reduced and you achieve full range of motion (2-4 weeks, generally) you can begin resuming activities. But you should speak to your orthopedist to get realistic expectations.
