Monks were semi-revived in 2ed, first as a Priest Kit in the Complete Priests Handbook. (No armor, more possessions than you can carry, gains tumble and ride as NWP's, gains stacking specialization in either unarmed combat or wrestling. (Still had to use those awful charts) Limited in spellcasting ability.
In the Players Options books, Monks were brought back again as a new priest class. This new version was closer to the 1sed incarnation (Took advantage of both Martial Arts and Weapon Mastery rules, gained a smattering of funky monk abilities) Still essentially a quirky Cleric who fought hand to hand.
I understand there was a 2nd edition version of the Monk in a Greyhawk Scarlet Brotherhood book as well, but I've never seen it.
All in all, you could say that yes, the monk was around in 2nd edition, but was a very different animal from either the 1st or 3rd edition incarnations. The Sacred Fist Prc is probably the closest you can get now to the 2nd edition monk.
