Two options.
A clearer comparison.

Lateral wedge insoles

knee

What happens

Select and fit the aid; ask for instruction on safe use.

Onset

Assess comfort and function while using the aid. A change in joint loading does not guarantee pain relief.

Duration

Support is provided while the aid is used; it does not reverse arthritis.

Repeat treatment

Recheck fit if symptoms, skin comfort, or function change.

Recovery

Ask about skin checks, footwear, balance, and safe activity.

Cost components

Device, fitting, adjustment, and replacement costs.

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.
