What is the typical time for knee swelling to go away after meniscus arthoscopic and acl reconstruction surgery?

Varies with surgery: Most of my arthroscopic surgery patients for menisectomy have most of their swelling gone within a few days and are walking normally within a week. For the acl patients, the time frame would probably be more like 4-6 weeks.

Timeline varies depending on factors such as age , BMI, severity of injury , whether or not there are other damaged areas like the chondral surfaces

1-4 weeks: It sometimes depends on the type of reconstruction as well as bleeding within the joint. Because of this, it is difficult to predict the amount and duration. Most of these resolve as the body seals and starts to heal. The body also starts to absorb everything over the first month.
Dr. Robert Meislin

Swelling: Swelling in the knee for acl surgery can last at least 3 weeks; for isolated meniscal surgery swelling can last 1 week.
