NRL Physio had recovery at 6 to 9 months. He'll be bang on 6 months pretty much.
People recovery differently. Perhaps those two examples are more outliers and looks like Roberson was eyeing a 9 month return but had other things set him back, not just patella injury but a **** run of other things going on.
"Roberson ruptured his patellar tendon in his left knee in January 2018 while elevating to catch a lob on a backdoor cut. His initial timetable had him set to return in November 2018, but he had a setback when a loose suture caused irritation and required an additional surgery. He was progressing toward a return six weeks later, but then had another setback, suffering an avulsion fracture in his knee after coming down from a jump. Following the second setback, which included a timetable of six weeks, Roberson made progress toward a return but never got back on the court that season."
Anyway ....I'm sure we can all agree it's great news he's back this early, I'm sure the club isn't rushing him back.
