I certainly do not have any insider info like I used to, but having seen similar injuries, I’m guessing it’s a support issue (muscular). For you and I, the surgeon do their thing and send us on our way telling us to be careful with it for a little while and slowly get back into things. With these high level athletes, they want to make sure the muscles around the injury are as strong as they can be to support the work the surgeons did because that is what is needed. Obviously building muscles on an injured appendage can be difficult and he likely lost a lot of strength during his inactivity following the repair.
Again, just my insight. OnlyU is great and I hang on his every word because he has earned it, but the fact that he missed this one just tells me moreso that it’s a strength\muscle support concern as everyone builds that back on different time frames.
