Maybe, but you need to make sure it's the rings and not something else before you start tearing off the head, etc.

With your engine cold, pull out a spark plug and do a compression check. Then, squirt some oil in the cylinder and redo the check. If your compression goes up significantly, there is a good chance that you have worn rings.

If it is the rings, maybe you could try throwing in a can of motor honey etc. This IS NOT a fix but might get your car to go a bit further before you have to tear into it.
