Genetic predisposition to joint disorders

Diagnostic Tests Before Procedure

Before performing the injection, healthcare providers may conduct the following tests:

X-rays to assess joint damage or degeneration
MRI to evaluate soft tissue structures around the joint
Ultrasound to visualize joint effusion
Blood tests to rule out infections or inflammatory conditions

Procedure Description

The injection procedure typically follows these steps:

The patient is positioned comfortably, and the skin over the joint is cleaned with antiseptic.
Local anesthesia may be administered to minimize discomfort.
Using a sterile syringe, the healthcare provider inserts a needle into the joint space.
The therapeutic agent, such as corticosteroids or hyaluronic acid, is injected.
The needle is withdrawn, and a bandage may be applied to the injection site.

Patients should follow these guidelines before the injection:

Inform the healthcare provider about any allergies, medications, or medical conditions.
Avoid blood thinners or anti-inflammatory medications for a few days prior, if advised.
Wear loose-fitting clothing to allow easy access to the injection site.
Arrange for transportation if sedation is used during the procedure.

Recovery and Aftercare

Post-procedure care is essential for optimal recovery:

Rest the joint for 24-48 hours after the injection.
Apply ice to the injection site to reduce swelling.
Avoid strenuous activities for a few days.
Follow any prescribed medication regimen, including pain relievers if necessary.
Monitor for signs of infection or unusual pain.

Possible Complications
