I am 20 y/o and I injured my knee in jan- strained acl/mcl/lcl, distal femoral avulsion, sublux patella. I went thru pt for a month or so and am back to normal except that I cannot bear any weight on the affected knee unless it is totally straight. Also it will occasionally lock up and click, grind, etc. With no warning. It is very sore at times, particularly lateral to the patella and in the popliteal area. I saw my ortho doc yesterday and he scheduled arthroscopy to check for a torn meniscus (or debris from the avulsed bone) and a possible lateral release.
Has anyone else had experience with this kind of thing? If so, I would really appreciate any input! Thanks in advance.

I am also a lil scared about gen anesthesia. Im usually not a crybaby, but im afraid I wont wake up, ill get an embolism, etc.
