What tissues are incised to perform knee arthroscopy?
My six-year-old just went through knee surgery to treat a torn discoid meniscus. I'm curious about which tissues were touched in the procedure (and are now of course now having to heal).
Disregarding the meniscus itself, are incisions made exclusively in the skin or are there additional parts (muscle? tendon?) that have to be cut to get to the interior of the joint?
Here are some details of my trouble finding an answer to this question myself. This fairly detailed article, for instance, mentions "incisions through skin, subcutaneous tissues, fascia and muscle," but doesn't get any more specific, and for the end of procedure, simply says, "The wounds are closed with non-absorbable sutures." And in a couple of videos I've sampled, it seems the procedure goes straight from making the portals through the skin, to doing the main part of the surgery.

The video linked in the first comment to my question doesn't say what is cut to make the portals, but it does mention the existence of the knee "capsule" (cartilage, I believe).
I finally googled "portals through knee capsule" and the top result (Arthroscopic approach to the posterior compartment of the …) says, "The entry point skin and capsule are incised…". So I suppose with that, I may well have my answer. Thank you, Mr. Gregory.
