In an analysis of "European companies around their buyout event in the period 2000 - 2008," private equity was found to "select companies which are less financially distressed than comparable companies prior to the transaction and that the distress risks increase after the buyout" [1]. Critically, however, "the distress risk in private equity-backed companies does not exceed the distress risk in comparable companies three years after the buyout," and, "despite this risk increase, private equity-backed companies do not suffer from higher bankruptcy rates than the control group."

More broadly, an analysis of "17,171 worldwide leveraged buyout transactions that include every transaction with a financial sponsor in the CapitalIQ database announced between 1/1/1970 and 6/30/2007" found bankruptcy rates around 6% [2]. This isn't exceptionally high.
