if the bearings aren't scored or overheated, then they can be reused, but they are so cheap you might as well get new ones.

What causes rod knocking?

A rod knock is a deep rapping sound that comes from within the engine. It is caused by rod-bearing wear or damage. The vehicle's connecting rod bearings have excessive clearance, causing additional movement. As the piston changes direction, the metal starts hitting metal, which produces the knocking noise.

Is it worth fixing rod knock?

Rod knock is a serious issue with your engine—it means the engine is not functioning properly. If you start to notice rod knock, this isn't a problem that will just resolve itself—you must take immediate action and replace the rod bearing while also fixing any other parts associated with the sound.
