Genicular artery embolization

knee

What happens

An interventional radiologist assesses suitability for selective embolization of small arteries around the knee.

Onset

A reliable personal timeline cannot be predicted from the evidence reviewed here. Agree on a review date before starting.

Duration

Benefit and durability depend on the exact intervention and population. The evidence section below explains what is known.

Repeat treatment

Ask about uncertain durability, alternatives, and how persistent symptoms would be managed.

Recovery

Obtain instructions for the vascular access site, activity, and signs of vascular or tissue complications.

Cost components

Consultation, imaging, embolic material, procedure/facility charges, and follow-up.

Corticosteroid injection

knee + hip

What happens

Clinical assessment and an injection of a specified corticosteroid into the joint when appropriate.

Onset

Ask when to expect the specific medicine to work and when lack of improvement should trigger review.

Duration

NICE describes short-term relief of about 2–10 weeks; response varies and some people do not benefit.

Repeat treatment

Repeated injections require review of benefit, risks, and any planned surgery.

Recovery

Ask who provides follow-up, what symptoms need urgent attention, and what restrictions apply to you.

Cost components

Consultation, medicine, injection, any imaging guidance, and follow-up.
