As paraphrased on Wikipedia, a fellow by the name of John JF Sawyer says, of that passage of Isaiah:
"Isaiah seems always to have had a prominent place in Jewish Bible use, and it is probable that Jesus himself was deeply influenced by Isaiah, and that he took it as his destiny to fulfill Isaiah ("a man of suffering, and familiar with pain... he bore the sin of many"). Thus many of the Isaiah passages that are familiar to Christians gained their popularity not directly from Isaiah but from the use of them by Jesus and the early Christian authors..."
And even that's assuming a lot that hasn't been shown...
