A GFC knee injection usually involves an orthopedic assessment, a blood draw, laboratory-style processing of the sample under sterile conditions and injection of the resulting autologous concentrate into the knee joint. Protocols differ, so the exact volume, guidance method and number of sessions should be confirmed with the clinic.
Before the procedure
Tell the doctor about fever, skin infection, recent antibiotics, blood disorders, anaemia, pregnancy, allergies and all medicines or supplements—especially anticoagulants and antiplatelet drugs. Do not stop prescribed medicine without advice. Existing X-rays and prior injection records are helpful.
During preparation and injection
Blood is collected and processed to separate the desired concentrate. The knee is cleaned, and the preparation is injected using sterile technique. Some clinicians use ultrasound guidance depending on anatomy and practice. The visit length varies with the preparation system.
The first few days
Temporary soreness, fullness or swelling may occur. Follow the clinician’s instructions on activity, cold packs and medicines. Avoid starting unapproved anti-inflammatory drugs because protocols may differ. Resume exercise progressively rather than testing the knee with strenuous activity immediately.
When to contact the clinic
Seek prompt advice for fever, increasing redness, marked swelling, severe worsening pain, wound discharge, calf swelling or feeling unwell. Joint infection is uncommon but serious and should not be mistaken for a normal post-injection flare.
Rehabilitation remains important
An injection does not rebuild strength or correct movement patterns. A tailored exercise and weight-management plan, where appropriate, remains part of long-term knee osteoarthritis care.
Frequently asked questions
Is anaesthesia needed for GFC injection?
Most intra-articular injections are outpatient procedures using local measures as required. Ask the treating clinic about its specific protocol.
Can I drive home after GFC?
Driving advice depends on the injected knee, pain, vehicle and any medicines used. Arrange transport unless the clinic confirms that driving is safe for you.
Good aftercare is simple but specific: follow the treating clinician’s instructions and report symptoms that worsen instead of settling.
Frequently Asked Questions
GFC knee injections are generally performed as outpatient procedures. The exact visit length depends on blood collection, processing and the clinic’s injection protocol.
