Hi,
Treatment for a knee problem or
injury may include
first aid measures, rest,
bracing,
physiotherapy, medicine, and in some cases surgery. Treatment depends on the location, type, and severity of the injury as well as your age, health condition, and activity level (such as work, sports, or hobbies).
Avoid high-impact exercise, such as running, skiing, snowboarding, or playing tennis, until your knee is no longer painful.
There are many types of knee braces, from soft fabric sleeves to rigid, metal hinged braces, that support and protect the knee. If your doctor has recommended the use of a knee brace, follow his or her instructions. If you are using a knee brace to help prevent problems, follow the manufacturer's instructions for use.
I do hope that you have found something helpful.
