If he doesn't feel it's any problem, but if the doctors suggest on theor observation..I would recommend him to wait. If you can hit 84 in a T20 why should he go for an operation?? That problem (identified by docs) may be natural to him.... I think he should wait untill he faces problem...premature operations specially in knees can make it worse, I'm a sufferer of that myself...
