Glenn Stewart has prosthetic finger joint after dislocation FINGER INJURY: Manly's Glenn Stewart. MANLY backrower Glenn Stewart's desperation to stay on the field in the 2012 NRL season didn't cost him an arm and leg, but it almost cost him a finger. The sidelined Test and NSW Origin star said the left middle finger he first dislocated in last year's opening round match got so bad he had to have a prosthetic joint put in. "I was in the wars a little bit last year, round one I dislocated it and did a bit of damage to the tendons," said Stewart, who is rehabilitating following a second bout of knee surgery that's expected to sideline him until about round eight. I had surgery (on the finger) straight after that and had seven weeks off. I came back and about two weeks after I re-did it. Pretty much for the rest of the year it was dislocated. It was the wrong part of the year to have more time off and rehab it. So I did a bit more damage playing with it, then went in for surgery again. I ended up getting a prosthetic joint put in. It's half ceramic, half plastic. I wasn't in very good shape at all. The joint was pretty badly corroded away. Doctor (Mark) Perko has done an amazing job to get it back to where it is. So ugly did the finger become that Stewart claimed teammate Jason King had to leave the dinner table one night because it was turning him off his food. Stewart said he had no strength to grip with the finger last year, and after the surgery he had to have rehabilitation three times a week to get the finger to operate normally "because everything had been stuck out of place for so long it had to be taught again." But while his finger woes may be behind him, Stewart has another battle to get back on the field with the knee he had cleaned out at the back-end of last year requiring a second round of surgery. Stewart said his reached a point in his rehabilitation from the first operation and couldn't go any further. Then at the start of last month he went under the knife again, with a return not expected until about round eight. "It was a lot of hard work to get back, and to be starting from scratch again was pretty frustrating considering this time of year you want to be starting in round one," Stewart said. Now I am back doing what I was doing before Christmas.
