The recovery time after knee injections is typically minimal, with most patients able to resume normal activities within a few hours to a day after the procedure. However, it is generally recommended to rest the knee and avoid strenuous activities, such as heavy lifting, running, or high-impact sports, for 24 to 48 hours following the injection. This allows the injected medication to take effect and helps minimize any potential side effects, such as soreness or swelling.

In some cases, particularly after platelet-rich plasma (PRP) injections, the recovery period may be slightly longer as the body’s natural healing processes are activated. Patients may experience some inflammation or discomfort in the days following the injection, but this is typically a sign that the treatment is working. Your healthcare provider will provide specific post-injection care instructions based on the type of injection and your individual needs. Following these guidelines can help ensure the best possible outcome from the treatment.

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.
