Early management of sprains and strains
Minor injuries to the knee, such as a mild sprain or strain should settle with time and can be managed at home.
A sprain or strain to the knee may result in the following:
- Stiffness and loss of function
The pain can be particularly strong in the first three weeks as this is the inflammatory phase of your body healing itself. Typically, these injuries last 4 to 6 weeks depending on the severity.
Painkillers like paracetamol will ease the pain, but need to be taken regularly in order to control the pain. Always follow the instructions on the packet.
Anti-inflammatories like ibuprofen can help with swelling, and therefore help you move more freely. Follow the instructions on the packet and discuss using them safely with a pharmacist, especially if you have any underlying health conditions
However, you should not take ibuprofen for 48 hours after an initial injury as it may slow down healing.
Up to date guidelines can be found on the NHS website:
Go to an urgent treatment centre or the emergency department if you:
- have severe pain or feel faint, dizzy or sick from the pain
- heard a snap, grinding or popping noise at the time of the injury,
- had a large amount of swelling which appeared instantly after the injury (within an hour)
- you are unable to weight bear because of the pain
These might be signs of a more severe injury which may need medical attention.
Speak to a GP or physiotherapist if:
- the pain is severe or stopping you doing normal activities
- the pain is getting worse and/or keeps coming back
- the pain has not improved in any capacity after treating it at home for 2 weeks
- you have ongoing symptoms of giving way or locking

How to manage a sprain or a strain
DAY 1 – Early Management
Protect by minimising use of the affected area and initially avoiding stretching the area which could cause further injury. You may require the use of a walking aid to offload pressure on the affected side. You may find it easier to go upstairs leading with good leg first, and downstairs with the affected leg first.
Rest can be beneficial in the very early stages of the injury (days 1-4). Complete rest, however, is not advisable. In the early stages, gentle active movements and specific exercises can help decrease pain and swelling, they also promote good tissue healing with less unwanted scar tissue and joint stiffness. It is important to make sure you keep your hip and ankle moving as able, so they do not stiffen up.
Ice pack/frozen peas wrapped in a damp cloth, placed on the swollen area for up to 20 minutes at a time, 3 times a day. So long as there is swelling you will need to continue ice therapy, often beyond the third week.
- Please note only use ice if you have normal skin sensation
- Check the skin regularly
- Stop if there is excessive pain, numbness or tingling
- Do not put ice directly on to the skin as this may cause a burn.
Compression of the knee can be achieved by using a tubigrip or crepe bandage. It should compress firmly but not restrict blood flow and create a tourniquet. Remove if there are signs of poor circulation, or if you start to experience pins and needles or numbness.
Elevation. If you have swelling in your knee, try to keep it level or slightly higher than your hip. You can help achieve this with use of pillows.

WEEK 1 – Early Mobilisation
After 72 hours is important to start using your knee as your pain allows. Start to do normal everyday activities. You should also try doing these exercises 3 – 4 times a day. Repeat each one 10 times.
WEEK 2 – Strengthening Exercises
You can start these when pain is starting to settle.
a) moving the foot of your affected knee closer to you and then progress to
b) standing from a lower height.
As you start to do these exercises you may feel there is some discomfort, however, this is okay and you should continue. If you have discomfort and pain for more than 2 hours after these exercises, then you should reduce the number and gradually build up again.
Recovery time and returning to activity
It usually takes 6 weeks to heal from simple soft tissue injuries to the hip or knee. However, everyone recovers from injuries at different rates. Some may be back in a few days however for some it can take a number of months.
Returning to work – Gradually build up your strength and function, practice doing similar tasks that you would do at work before returning. Start doing this little and often ensuring there is minimal pain or swelling.
Returning to hobbies or sport – it is advised not to return to these activities until you have full strength and range of movement without pain or swelling. Try to practice the specific movements of your hobby or sport in a controlled manner and build up the time and intensity that you do the movements before returning to your activity in full.
