A knee sprain can occur when you injure or twist your knee awkwardly. This may cause damage to the tissues in and around the knee such as the muscles, ligaments and/or cartilage.
Sprains and Strains
Sprains and strains are common injuries affecting the muscles and ligaments. Most can be treated at home without seeing a GP.
Its likely to be a sprain or strain if:
- you have pain, tenderness or weakness – often around your ankle, foot, wrist, thumb, knee, leg or back
- the injured area is swollen or bruised
- you can’t put weight on the injury or use it normally
you have muscle spasms or cramping – where your muscles painfully tighten on their own
For the first couple of days, follow the 4 steps known as RICE therapy to help bring down swelling and support the injury:
1.Rest– stop any exercise or activities and try not to put any weight on the injury.
2.Ice– apply an ice pack (or a bag of frozen vegetables wrapped in a tea towel) to the injury for up to 20 minutes every 2 to 3 hours.
3.Compression– wrap a bandage around the injury to support it.
4. Elevate– keep it raised on a pillow as much as possible.
To help prevent swelling, try to avoid heat – such as hot baths and heat packs – alcohol and massages for the first couple of days.
When you can move the injured area without pain stopping you, try to keep moving it so the joint or muscle doesn’t become stiff.
After 2 weeks, most sprains and strains will feel better. Avoid strenuous exercise such as running for up to 8 weeks, as there’s a risk of further damage. Severe sprains and strains can take months to get back to normal.
