Sprain or strain: what is the difference?
A sprain injures a ligament, which joins bone to bone. A strain affects a muscle or tendon. Similar symptoms can come from different tissues.

A personal plan
What can help?
-
Assess the injury
Significant pain, swelling or instability needs an examination.
-
Protect and settle symptoms
Avoid aggravating loads; wrapped ice, elevation and suitable compression may help.
-
Restore comfortable movement
Begin appropriate movement as pain allows and follow injury-specific limits.
-
Rebuild before returning
Progress strength and activity with guidance for more significant injuries.
Support as part of care
Where a knee brace fits in
The right device depends on what is injured and how much protection it needs.
- Comfortable compression may help manage swelling in suitable injuries.
- Adjustable coverage allows a comfortable fit with a wrap.
- Ligament protection when prescribed may require a hinged or rigid brace.
- Support through rehabilitation can complement the recovery plan.
Support has limits. A general wrap cannot replace prescribed stabilization. Feeling supported does not confirm that a ligament has healed.
Different designs. Different needs.

Your next step
Match your support and activity plan to your needs.
How is it assessed?
- Your clinician reviews the injury and examines movement and stability.
- X-rays may be used if a fracture is suspected.
- MRI may help assess significant ligament, tendon or meniscus injuries.
When should I get checked?
Get urgent care for deformity, a cold or numb foot, inability to bear weight, major swelling or a locked knee.
