The question isn't if he's any less injury prone than Bailly. The question should be if he's injury prone and the evidence suggests he is. He has missed too many games for my liking and having such disruption in game consistency affects potential partnerships from developing and game rhythm.
Konate has only suffered one injury of note in his fledging career thus far and it would be naive to suggest he's injury prone without context.
I'm sure Dante will be along to tell the forum how Adnan has come along to bring up Konate again.
Below is a link to a popular Barca forum with many members valuing technical ability highly which isn't a surprise due to the adopted principles of Cruyff. The below link is a thread on Konate from last year and many Barca fans rate Konate as having more potential than Upamecano and also describe Konate as being technically strong which isn't a surprise to anyone who has watched him play.

I'll also leave this here for the statisticians to chew on regarding technical ability for a CB.
