Jonathan Robinson performs joint injections (cortisone/prp) in New York when it is the right step, and reviews every alternative with you first.

What is Joint Injections (Cortisone/PRP)?

Joint injections place medicine directly into or around a joint to reduce pain and inflammation.

They are one part of non-surgical care, not a stand-alone cure.

Common types include corticosteroid, which calms inflammation; hyaluronic acid, which adds lubrication in some arthritic knees; and platelet-rich plasma, or PRP, made by concentrating factors from a sample of your own blood. Each works differently and suits different situations.

Injections are often used alongside physical therapy and activity changes. The right choice depends on the joint, the diagnosis, and your goals.

What happens during Joint Injections (Cortisone/PRP), step by step?

The joint area is cleaned and, when helpful, numbed.

The medicine is placed with careful positioning, sometimes guided by ultrasound or X-ray for accuracy. PRP is prepared by drawing a small blood sample and concentrating it before injection. The visit is usually brief, and Dr. Robinson will explain aftercare for the specific injection.

What is recovery like after Joint Injections (Cortisone/PRP)?

Effects vary by injection type and person.

A corticosteroid injection may ease pain for weeks to months, hyaluronic acid may take a few weeks to help, and PRP responses vary, according to general guidance from the American Academy of Orthopaedic Surgeons. These are ranges, not promises. Injections are tools within a broader plan, and Dr. Robinson will track how you respond and adjust care.

What do patients ask most?

What is the difference between a cortisone shot and PRP?
A corticosteroid, or cortisone, injection reduces inflammation and pain for a period. PRP concentrates factors from your own blood and is used to support healing in select cases. They work differently and suit different situations.
How long does a cortisone injection last?
Relief commonly lasts weeks to months and varies by person and joint, according to general guidance from the American Academy of Orthopaedic Surgeons. This is a range, not a promise.
Is PRP covered by insurance?
Coverage varies, and PRP is often not covered. The office can explain what to expect for your plan before you proceed.
Are joint injections a substitute for surgery?
No. They are part of non-surgical care that can reduce pain and delay or avoid surgery for some people. When they no longer control symptoms, surgical options are discussed.
