I covered the panic – which was international in scope, not confined to the US – extensively while it was underway, and summarised the key details and impacts in an earlier answer here, which should offer much of the information that you're after:

Any good research on the Satanic Abuse Panic of the 90s?

To address one specific part of your question, however, there were a significant number of convictions as a result of court cases brought during the panic, both in the US and UK. These included the McMartin and Oakhill cases in the US, a Washington State case that was the subject of a long New Yorker article, and later a book, by Lawrence Wright, and the Nottingham and Pembroke cases in Britain. In that sense, several juries decided that there had indeed been "real" Satanic crimes. In all of these cases, however, it's fair to say substantial doubts have been raised regarding the convictions in retrospect. In perhaps the most extreme of these, the two defendants on the Oakhill (Texas) case had their convictions thrown out after each had served a 22-year sentence for sexual assault.

One notable characteristic of the best known cases was the lurid and incredible nature of the allegations made. In the Oakhill case these included "dismembering babies, torturing pets, desecrating corpses, videotaping orgies and serving blood-laced Kool-Aid". Other allegations in other cases included trips taken in flying saucers, children flushed down toilets or disposed of in shark tanks, and nude Satanic orgies conducted in sub-zero February conditions on windswept beaches in West Wales.
