How Is Knee Infiltration Performed?
Infiltration in the knee can be done in a doctor’s office. The technique can be performed in the orthopedist’s office, that is, in an outpatient setting. The professional who will perform the procedure must have experience in this type of procedure. Imaging tests such as ultrasound or X-ray can be used to determine the exact injection site.
The region is cleaned, disinfected, and anesthetized locally. Sterile and disposable materials must be used. Next, the drug is injected. The procedure is quick and takes no more than a few minutes. The procedure causes some pain and discomfort, but it is bearable.
Afterward, the patient must rest and not do physical activities for at least two weeks. If there is difficulty walking, the doctor may recommend using crutches while this difficulty is present. It is important to remember that all the treatment that the patient underwent must continue; physiotherapy sessions are necessary, as the infiltration will only offer temporary relief to the problem.
Therefore, muscle strengthening sessions and improvement of joint mobility are still necessary after knee infiltration.
What Are The Risks And Side Effects Of Knee Leakage?
When performed by a trained, experienced professional and correctly indicated, knee infiltration usually results well. Immediately after the injection, the knee may become swollen, and the patient may experience local discomfort and pain. This is normal, so rest is required for the first few hours after that.
Before performing the procedure, it is necessary to notify the doctor if you have any allergies to steroids. It is important to remember that for those with diabetes, steroids often significantly alter blood glucose, so there must be reasonable glycemic control after the procedure, with adjustment of insulin doses, when necessary.
Another critical factor is to alert your orthopedist if you are taking any anticoagulant, such as heparin or acetylsalicylic acid, and if you are pregnant or breastfeeding. There are low risks to the procedure when performed correctly. Inform your doctor if you develop a fever one day after the procedure. The risk of infection is 1 in 70,000, which is relatively low.
Another complication is reactive synovitis, but this is a situation that can be quickly resolved by the orthopedist, who should always be warned in case of excessive pain or fever. Search for loose knee symptoms (เข่า หลวม อาการ which is the term in Thai)
