- Drop some nearby terrain/stone blocks/whatever onto the monster. It doesn't get free from them until you've stepped away.
- Cut muscles or tendons such that the monster takes some time to painfully rise to its feet.
- Bash the monster painfully against the side of its head, causing it to lose its balance.
The 'can't move until you're no longer adjacent' bit, as was covered earlier, is explained pretty well just by having the fighter threaten a nasty blow if the monster tries to rise while he's within attack range.
