How Many Knee Injections Are Needed?
The number of knee injections needed varies depending on the type of injection, the condition being treated, and the patient’s response to the therapy. For corticosteroid injections, one injection may provide sufficient relief for several weeks to months, but in some cases, repeated injections may be necessary. However, due to potential side effects, healthcare providers usually limit the number of corticosteroid injections to no more than three to four times per year.
Hyaluronic acid injections are often administered in a series of three to five weekly injections, with the effects typically lasting up to six months. After the initial series, additional injections may be recommended every six months if the patient continues to experience pain and reduced mobility. Platelet-rich plasma (PRP) injections generally require two to three injections spaced several weeks apart, with the potential for follow-up treatments depending on the patient’s progress. The exact number of injections should be determined by a healthcare provider based on the patient’s specific needs and the severity of the condition being treated.
