Why Do We Perform Knee Injections?
Knee injections treat conditions such as osteoarthritis, bursitis, and meniscal tears. They help reduce pain, improve mobility, and promote healing.
Are Knee Injections Safe and Do They Have Side Effects?
Knee injections are generally safe. Potential side effects may include temporary pain at the injection site, infection, and allergic reactions. Repeated corticosteroid injections can cause joint damage. Sterile techniques are used to minimize risks.
What to Expect on Injection Day
The procedure takes about 15-30 minutes. Your physician will clean the injection site and may use a local anesthetic. The medication is then injected into the knee joint, often using ultrasound guidance for accuracy.
Will This Injection Help Me Avoid Surgery?
Knee injections can delay or reduce the need for surgery. Your physician will assess your condition and discuss all treatment options, including whether surgery might be necessary.
Is There Anything I Need to Do Prior to Injection Day?
There are usually no dietary restrictions before the injection. Your physician may ask you to stop taking certain medications, such as blood thinners, before the procedure. Follow any specific instructions provided by your physician.
Can I Repeat This Injection?
The frequency of injections depends on your condition and response to treatment. Corticosteroid injections are typically limited to 3-4 times a year to prevent joint damage. Per your physician’s recommendations, PRP and hyaluronic acid injections may be repeated.
Risks Associated with the Injection
Pain: Temporary pain or discomfort at the injection site.
Infection: Rare, minimized by using sterile techniques.
Allergic Reactions: Rare, but possible.
Joint Damage: Repeated corticosteroid injections may cause joint damage.
When Should I Call the Doctor or Go to the ED?
Contact your physician or visit the Emergency Room if you experience:
- Increased redness or warmth at the injection site
- Drainage from the injection site
- Fever > 100.4°F
- Severe pain not relieved by over-the-counter pain medication
