I feel you, but everyone is different. Former D1 college track athlete. I tore my ACL and the back half of my lateral meniscus in my early twenties playing flag football of all things (bad turf should be outlawed). My experience was much more like that
@Govoner Vaugn Fan described. For context, I have a cadaver Achilles tendon as my ACL, rather than having part of my hamstring taken out. Six months post-surgery, I was stronger than I was pre-injury. Nine months post-surgery, I was every bit as explosive as I was pre-injury. However, that mental block was an absolute b****. My knee was fully stable and strong, but it took me an easy five more months before I felt comfortable. When I played basketball, I took runners and layups instead of going up for a dunk. When I played a sport that needed me to cut, I would decelerate into it. I was legitimately scared to hear those audible pops and feel that shotgun blast to my knee again. I had literal nightmares about it.
Medical science in this day and age is pretty darn incredible. An athlete can absolutely physically get back to where they were in no time. For me, the physical rehab was relatively easy (though, let me tell you, there were a lot of sweat and tears). The mental rehab took longer and was way, way harder.
