User blog comment:Riffkid23/Oghma Infinium Glitch after 1.9 Patch/@comment-1992639-20130418175930

You can theoretically edit the savegame with an advanced program, making the game think the savegame is of an older version. Most games store a version number in the savegame, to prevent backwards patch issues, as it raises thousands of "why won't my save work as it should" questions. It's not advicable to edit a save, a newer patch may write away data differently, making the save act strange and bugged permanently.

Unless you're not on PC, just cheat your stats to 100 with the command console. Or use one of the many tips in the skill pages on how to rapidly grind your skills to 100.
