What is a Knee Splint Used For?

A knee splint is also known as a Knee Immobilizer. It is a simple device used to keep the knee fully extended ( or completely straight to the person not speaking medical jargon).

Knee splints can be used following trauma but are also utilized after certain types of orthopedic surgery. In the E.R. they can be used as a temporary support until the full extent of the injury is known, but in other cases they are used as a definitive treatment and can be in place for 6 weeks or longer.

Knee splints do the same job as a plaster cast but have the benefit of being removable. This can be an advantage when there are wounds that need checking or when range of motion exercises are permitted at various stages of recovery.

Choosing a Knee Splint

The first consideration to be taken when choosing a knee splint is the length of time you expect to be in it. The main difference between knee splints is not the function of them, it is the comfort.

Just about every knee splint on the market keeps the knee safely in full extension as the requirements are fairly simple. The difference comes when you need to wear the splint 24/7 for the next 8 weeks. 

If you know this in advance, getting a quality splint is money well spent.

The Economy Knee Splint

Before you choose a knee splint check the sizing information. Some work on length and some on width. As a basic rule, a 20 inch length fits short to average height people and a 24 inch fits above average to tall people.

This 20" knee splint is around $20 and comes with 3 straps above and below the knee. It comes with a large amount of padding that can be trimmed to fit the thinner leg.

Simple and functional, this splint has a variety of uses.

Adjustable Width Knee Splint

A 3 panel knee splint allows a set length to fit any sized thigh circumference. The ability to instantly adjust the width ensures consistent comfort throughout the period of an injury as the level of swelling changes over time.

Simple Velcro width adjusters enable more or less accommodation as required.

Knee Splint for Patella Fractures

Knee Splints are often used following a Patella fracture as bending the knee can cause harm.

In these cases, the kneecap is tender and direct pressure can cause discomfort. If you have the chance to choose your own knee splint, opt for one like this with an opening at the front of the knee to relieve pressure on the effected area. 

When you are going to be wearing it for the next 6 weeks, little factors like this are easily worth the extra $20.

I need one sooo bad I think I dislocated it when I hit the ground hard. I was running to get to class and I did a jump-stop and I felt it come out of place. At first I was in a lot of Pain then I was worried i might collapse on the ground it felt horrible I might need a 24" Knee immobilizer to keep it straight. I wonder what my friends will say when I come back with a Knee immobilizer. :(?

Sad looking I'm not sure but it's only for 8 weeks about. I hope this will be a good thing
