He's playing through pain in his knee...has been for weeks now. So he's not 100% at all. He'll take a break before Indian Wells.
Source: Raonic plays through pain
Upon arrival in San Jose ... he consulted a noted orthopedic surgeon at the Stan-ford Medical Centre and had a proper MRI done. The results - no results, really, just some wear and tear on the tendon - assuaged Raonic's concerns about doing long-term damage to the knee by continuing to play.
It was hardly that easy. Raonic began taking a combined painkiller/anti-inflammatory medication, even for practices. But he still felt it.
"The painkiller made that [the pain] wasn't really constant. But I felt it if I jammed my leg, or maybe on a long point if I stopped a little bit aggressively," Raonic said.
That aching left knee is the one that bears the brunt from his serve, the one he lands on. And with all the work on the other side of his body, in the wake of last July's surgery on his right hip, he said the left side got a little weak biomechanically. The quad is putting more of a load on the knee tendon, hence the wear and tear, the tendinitis.
