Edit: also, what is the service history? How long have you owned it. It just seems odd for any car without a defect to get rod knock with such low mileage.
I was going to ask this, too. Spend some more time diagnosing to be sure what the problem is, then make a plan to fix it.
If it is a rod bearing, I wouldn't just replace the bearing and be done with it. It would probably fail again in a short time. If the crank journal is rough, or if the rod big end is mis-sized, the bearing won't survive. In this situation, getting a new crank and rod set may be the best way to go.
Another diagnostic question: Did the oil pressure decrease when the noise started?
