Joint injections,
placed precisely.

At a glance

A joint injection places a selected medication or biologic preparation inside or around a painful joint after evaluation identifies an appropriate target. Institute of Function starts with diagnosis and rehabilitation, considering the least invasive effective option and procedures only when examination supports them. Dr. Benjamin (Ben) Klyachman, D.O., board-certified in pain medicine and physical medicine and rehabilitation, leads care at Institute of Function in Nassau County, NY, which welcomes patients from across Long Island, New York City and beyond.

A joint injection places medication directly where it is needed, inside or around a painful joint. At Institute of Function in Nassau County, the choice of what to inject follows the diagnosis, and every injection is placed under image guidance within a rehabilitation plan.

Joints we treat

We perform injections for the knee, hip, shoulder and sacroiliac joint, as well as nearby structures such as bursae when they are the source of pain. An examination, and diagnostic ultrasound when useful, help confirm which structure is involved before anything is injected.

Choosing what to inject

Hyaluronic acid may be considered for knee arthritis where appropriate. A corticosteroid may be used when it's needed to calm a flare of inflammation, and it is never the automatic first choice. Regenerative options such as PRP may be an alternative for selected joints and tendons.

What the visit is like

The skin is cleaned, the target is confirmed with imaging, and the injection takes a few minutes. Procedures are image-guided, using ultrasound or X-ray guidance depending on the target. Most people walk out and return to light activity the same or next day.

Part of a plan

An injection can quiet pain enough to make strengthening and movement possible, which is where lasting change usually comes from. Results vary, and no outcome is promised. Joint replacement or other surgery is considered only when it is truly needed.
