Nicely done. There are alot of factors that determine the rate of recovery and you covered the important ones. One problem recovering from an ACL surgery is most patients feel they are nearly healed and push to hard. I’m sure his trainers will keep him under reins. An interesting thing to know is if they harvested part of the patella tendon to replace the ACL or if they used a cadaver ACL Usually the cadaver allows you to heal a little quicker but the one salvaged from the patella area has been reported to be a little more durable. WELL DONE.
