The recovery time from an arthroscopic procedure will very much depend on the extent of the operation. It can range from a relatively short 30-minute operation, such as a meniscectomy where you will be sent home the same day, to a more complicated ACL reconstruction which will require an overnight stay. It usually takes around 6 weeks to fully recover from arthroscopic surgery. In the case of tissue or ligament repair, a full recovery can take up to a year.
