I just had the surgery for My ACL and meniscus(two of them) in July. The first couple of days were really rough and I couldn't keep my pain under controls l depute meds.awns icing-but I have a really high tolerance to pain meds, always.have. I had p.t 48hourz after my surgery and started twice a week after that. Rode the stationary bike a week after surgery but it got easier each time I did it. Had my leg in a full leg brace untilled three weeks out then I got My shorter brace. Was on crutches for about six weeks before I was releases.fully from them(the Dr cleared me to go without then pt. Wanted me to stay with them, but p.t. is.the.ones you will see and will truly know what you're capable of). Follow ALL of your exercises religuosly, you will lose a good amount of muscle mass in your injured leg. But to make up for it your triceps will remain in good condition whilst you are using the crutches. And there are exercises you can do WITH the crutches, such as dips and leg lifts lol. I'm still looking at two more months before my return to the gym, and its partly due to the replacelent I had. I had the.hamstring gradft taken from me, which caused more muscle massloss and is a little longer with the healing but due to potential issues with the patellar options I decided hamstring was best for me. Your doctor will help you make That decision, in the meantime do some research. If you have surgery in December you will most likely be going back to school in crutches. If you Have any other questions feel free to ask!!!
