No, you can't write the sentence like that. First, while "though" and "although" essentially mean the same thing, they're used in different placed of a sentence. "Although" is typically used at the beginning of a sentence (or a paranthetical statement). "Though" can be used in various places, but it's usually tacked on at the end of the sentence. And the third one, "even though", is used without commas and typically placed somewhere in the middle. So, if you want to write this sentence properly, here are my renditions: ______________________ Although convicted of murder, Oscar Pistorius was the first amputee to win an able-bodied world track medal. Oscar Pistorius was the first amputee to win an able-bodied world track medal even though he was convicted of murder. Oscar Pistorius, though convicted of murder, was the first amputee to win an able-bodied world track medal. _______________________ To be honest, I don't like using "though" in this sentence. I'd switch it with "despite being", to make the third sentence: "Oscar Pistorius, despite being convicted of murder, was the first amputee to win an able-bodied world track medal." However, "though" is still grammatically acceptable. These three words are pretty tricky to use organically without a LOT of practice in an English-speaking country. To minimize mistakes, I'd say to use "though" when in doubt, because it has the most flexibility of the three.

Although and Though are interchangable conjunctions. This means either can be used in the sentence. I would write: Oscar Pistorius, athough convicted of murder, was the first amputee to win an able-bodied world track medal. Or Oscar Pistorius, though convicted of murder, was the first amputee to win an able-bodied world track medal.
