On the 26th of this month I'm having a patellar tendon graft to reconstruct the ACL in my left knee. The injury happened in July of last year and due to the NHS taking there sweet time in diagnosing what was wrong (despite me offering it as suggestion at every consultation and physio appointment) I haven't done any real training since, and am going stir crazy. I obviously want to get back to training ASAP but don't want to risk any further damage in my eagerness. Any advice would be greatly appreciated.
