Re-injured?

Hi everyone. I am about 11 weeks post op now from ACL reconstructive surgery (Quad Graft) and meniscus repair. Recovery and PT have been going good. This morning, I just got back from PT and my 90lb dog got excited and flipped his butt into my knee. It hyperextended backwards and a little to the side. It hurt and is a little swollen. I didn’t hear a huge pop or anything but I’m so paranoid that I reinjured it. I’m getting in my head thinking it’s making popping noises more than usual too. I’ve been so careful with it. I go back to PT tomorrow morning so I’ll obviously ask my physical therapist about it. Anyone else have similar things happen? 😅
