How many steroid injections for arthritis in the knee can a person have within a year before consideration of a knee replacement?

Varies: The recommendations vary, but in general i tell my patients that 3 injections in a 6 month period is the limit. If you think about it, you really would not want to keep getting them unless they were lasting longer anyway. There are other types of injections that can be done as well that may last longer such as synvisc (hylan g-f 20) as well. Thank you for your question.
