A combination therapy for treating osteoarthritis is disclosed. The combination therapy includes the co-administration of a steroid and Zoledronic Acid. The coadministration of a steroid decreases the production of cytokines, and, therefore, decreases the pro-inflammatory effects of Zoledronic Acid. The co-administration of Zoledronic Acid with steroids treats osteoarthritis, and helps to prevent the onset of osteoarthritis in patients at risk for osteoarthritis.
