I had ACL reconstruction surgery done almost 3 years ago. Hockey and ultimately beach volleyball were the culprits. I'm 46 now and tore the ACL about 5 years ago, so surgery 2 years after the tear. I have an active lifestyle and felt I needed the reconstruction surgery to continue to enjoy this lifestyle. There were several incidents of what I called "slide-outs" after the tear where I was doing very non-stress full movements like walking down the aisle at CT and turning/pivoting on the bad knee (to change direction for the cash register) when it would feel like my fibia and tibia were just wobbling about and I felt like one day it was just going to keep wobbling/separating and cause further damage so a repair was in order.
My doctor referred me to a surgeon who I think was terrific, Dr. Di Pasquale in Mississauga. The surgery only takes about 1-1.5 hours, you go home the same morning (as long as you have crutches and a ride). They harvested a hamstring to use to replace the torn ACL with, there other methods but this is the current favourite it seems. Physio starts 2 days afterwards. I wasn't much of a believer in physio beforehand but am now. I'm totally convinced that I wouldn't have recovered the full range of motion without it. I also believe that it helps to be in good shape beforehand, by good shape I mean having strong leg muscles. I didn't do much more than the minimum of physio and wish I'd done more. It reduces recovery time and improves the final result. My benefits covered the expensive brace (still from California and about $1800, can't remember if that was CDN or U.S.). I've almost completely given up sports but am told can do it without problem or much risk with the brace I just choose not to and it's ok. Biking, ice fishing, hunting, hiking, walking and some others I've chosen not to count as "sports"....lol.
My advice is start to mentally write-off a good chunk of the ice season (you'll have many more if you play this right), my surgery date was Feb.21 (I think) and what scared me even more was trout opener (slippery rocks and mud banks) so I skipped one year of this. Crutches, no working and no driving for 6 weeks (or until you can show enough movement) even though it was my left knee.
They want you using the knee as quickly as you can so be smart, don't push it tooooo much and you'll be good. Do the physio!!!....and then some
