In a study reported by the British medical journal the Lancet, corticosteroid injections eased the pain only during the first four weeks after the injections. By six months and at 12 months the effect had reversed to significantly favor no treatment. Even more telling was that repeated injections - ranging from 3 to 6 over 18 months - yielded poorer long term pain results than one injection.
In an accompanying editorial, the authors stated that there is insufficient evidence for the efficacy of steroid injections for Achilles and patellar tendinitis.
