Hi.
Thank you for reaching out to Health Care Magic.
Common causes of
knee pain include the following -
Muscle injury
Soft tissue strain
Cone really issue
A popliteal muscle strain
The fact that you mention that the knee is locking up may indicate a popliteal muscle issue. This is because the muscle causes the knee to lock after extension of the muscle.
One of the best regimen to promote healing of this is usually by using the POLICE regimen. POLICE stands for -
Protection - Protect the joint. Prevent injury and avoid excessive exercise.
Optimal loading - This is when the muscle is loaded to the right strain and right tension. In this tension, the muscle would heal quicker because the muscle can contract and relax allowing blood to flow smoothly
Icing the area for 15 mins at a time can be very useful for allowing healing and to reduce swelling
Compression - Using a knee sleeve for some part of the day may help
Elevation of the leg while lying down or sleeping can help with recovery by pushing blood back to the heart.
Along with this, many people find using OTC NSAIDs useful to reduce the swelling. Also, using a hot compress may help as well.
I hope this helps. Please reach out to me if you have any other questions.
