Please help if anyone knows what this means.
Basically, the ACL and PCL are the main ligaments holding your knee together from the inside. In your case, the ACL is partially torn.
The cartilage surfaces between your knee bones are cushioned by the meniscus (medial and lateral). Each meniscus has two parts—a front and back horn. You’ve got a tear in the back horn of the medial meniscus that goes into the tissue itself rather than out toward the side. As for the "joint effusion"—that's just medical speak for swelling.
Hope that clears things up.
If you happen to be young and an athlete, look at it this way—Serena Williams had to go under the knife for stuff like this at least three times.
