I'm 22 years old and want to enlist but 3 years ago I suffered a clean patellar subluxation no fragments or anything is floating around my knee and no surgery was needed. My knees were always strong and never had issues growing up it was just me being stupid and I twisted my leg in a wrong way. Anyway I did physical therapy and the doctor cleared me saying my patella/knee was stable. I pretty much healed up and went back to normal within a few months it has not been a recurring thing and I work a very physically demanding job already and so far keeping it strong and exercising my legs regularly has done well for me. Would I require a waiver or no? I heard that they only care if you've had 2 or more recurring instances when it comes to patellar subluxations or is that incorrect?
