Patella Knee Brace – Getting the perfect Fit

May 2nd, 2011

Patella braces are off-the-shelf braces. This means that there are a variety of set sizes, each covering a specific range of dimensions.

If you are right in the middle of the range between sizes this is not much of a problem. Unfortunately, there must always be those who sit right on the boundary between sizes. Although there is often a bit of overlap between sizes, many in the’ in between zone’ often find that neither the bigger nor smaller size fit comfortably.
Larger people are more likely to encounter this problem as they find the top border of the brace uncomfortably tight.

The choices for those in this situation is to either choose a different brand of brace and hope that the sizing chart is of a different dimension, or try a brace that is not based on the standard pull-on design.
To make matters more difficult I know of very few wrap around patella braces and they can be very hard to find.
The one I use to fit “troublesome” people is the original Wrap Around Tru-Pull by Donjoy.

It was the first brace in the Tru-Pull range and subsequent models used the same successful concept but utilized a Pull-on design. This made them more “User friendly” – as long as you were the right size.
Thankfully the original can still be found if you know where to look and its design allows it to fit and size (and both left or right) perfectly everytime.

If it is so good, why doesn’t everyone use one?


The main reason is that it is more difficult to put on. The application is more complicated than the average pull-on patella brace but once you have learnt it, the time to apply the Wrap around Tru-Pull is about the same as any other type of brace.

Who is it good for?


Those in between sizes
Larger People
Those likely to change body shape or size in the future (Diet / Swelling / Muscle Gain or Loss).

How is it applied?


Like all Patella braces, the Tru-Pull is put on with the leg completely straight and the quads relaxed. The buttress on the brace is placed next to the outside border of the patella. The patella is then pushed towards the midline throught the brace and held in this position as the brace is wrapped around the leg to secure it in position. One strap above the knee, one strap below.
The tension can be adjusted easily to provide more or less support.

How Do You Put on a Patella Knee Brace

March 19th, 2011

There is no point wearing a Patella Knee Brace if you don’t put it on correctly.

These braces work by applying a force that resists the kneecaps tendency to drift towards the outside of the knee. Different braces have different actions but (with the exception of the Donjoy S.E.R.F. Strap) they all push up against the outside of the patella directing it back towards the midline.

In order to correctly fit a patella knee brace you need to complete the following steps:

1) Prepare: Patella knee braces are ‘pull-on’ braces so your brace should be pulled up over the leg and positioned as per the manufacturers instructions. The starting position is having the leg completely straight and the weight supported. The best options are sitting flat on the floor with your leg straight out in front of you or sitting on a chair with the leg supported on another chair or stool.

Example of fitting position

2) Relax: The quadriceps muscle needs to be completely relaxed. You can check that you have achieved this by grasping the patella and trying to move it from side to side. If it moves the quads are relaxed. If it does not, the quads are still engaged, locking the patella in position. It takes a bit of practice to relax these muscles on command but it is a vital part of the fitting process.

3) Apply the force: While the quads are relaxed, the brace’s buttress is positioned next to the outside edge of the patella. This is the raised part of the brace that grips the kneecap and enables the force to be applied.  Placing your thumb on the outside of the brace at the position of the buttress, push the patella towards the inside of the knee and hold it there.

4) Lock Position: While your thumb holds the patella across towards the inside of the knee, use your other hand to apply the straps of the brace (under sufficient tension) to lock this position in place.

Effectively applying a Patella Knee Brace means ‘pretensioning’  the kneecap while the quads are relaxed. Pulling a patella brace on and just tightening the straps without following this procedure will not give the maximum benefit the brace is designed for.

If you are confused or feel you are not getting the most out of your brace, consult a physical therapist.

Will a Patella Knee Brace Work For Me?

February 26th, 2011

This is a common question for those who have not used a patella knee brace before.

Firstly, if you have been shown how to tape your patella by a physical therapist and you found this to be of benefit, it is extremely likely that a brace will work for you.  Patella knee braces are often used by people who have tried taping but have developed skin irritation or just got tired of the endless application of more tape. Tape has also been shown to gradually stretch over time making it less effective and as a separate issue, continuous taping also gets expensive.

Secondly, patellofemoral pain is often caused by muscle imbalance issues. These generally respond well to a tailored exercise program following a thorough assessment by a sports physician or physical therapist. Unfortunately, these exercise programs tend to take a minimum of 6 weeks to be effective. Many people are unhappy to wait this long for symptomatic relief and use a patella knee brace to decrease their pain while they work on their quadriceps.

Patella knee braces are are a safe and effective treatment and have many advantages over taping in the medium to long term. If you are unsure if a brace is suitable for you, discuss it with your chosen health care professional.

Patella Knee Brace for Running

Tru pull Lite 146x300 Patella Knee Brace for Running

The Donjoy Tru-Pull Lite

Anyone running medium to long distances needs a patella knee brace that allows a high level of mobility, is cool to wear and still provides a good level of support.

This narrows the field considerably. The first brace that springs to mind is the Tru-Pull Lite by Donjoy.

This brace is the latest edition in the successful Tru-Pull range and is designed for active users. It consists of a relatively short pull-on sleeve and a patella buttress secured by two full circumference straps.

The body of the brace is made with breathable material and the buttress that applies the corrective pressure to the patella is removable to allow for individual placement. Like all patella knee braces, once slipped on, the straps should be tightened with the knee fully extended and the quadriceps relaxed. This allows the patella to move freely and be pushed towards the inside of the knee while the brace straps are secured in this position.

This brace is particularly suited to those who develop patellofemoral pain after running for a while. This is usually a sign of muscle fatigue and a brace needs to allow normal movement during the initial period when there is no problem but provide sufficient support when fatigue leads to pain.

If you plan on running more than a couple of miles, the Donjoy Tru-Pull Lite is a good choice.

Inexpensive Patella Knee Braces

October 22nd, 2010

The latest, top of the range Patella Knee Braces can cost over $150.  For those with mild Patellofemoral Pain, this can be an unnecessary expenditure.

There is a range of braces that offer more modest levels of support but can be a very cost effective treatment in milder cases. These braces can can be bought online for less than $60 .

There are two different types of brace in this category.

Firstly there are the stabilizers. These basic braces look to place a raised buttress around the patella to resist any outwards movement of the kneecap. They do not actively push back the other way, they just make it harder for the patella to track abnormally. An example of this is the Procare Patella Stabilizer that can be bought for around $55

The other type are the active braces that push the patella medially. These were the braces that originally showed the value of Patella Knee Braces. Now that there are braces offering a higher level of support they have become very economical. One of the best selling examples is the Donjoy Lateral “J”, so named because of the J shaped buttress pushing against the patella.

If you manage everyday activities with occasional pain and are looking for some added support, this type of patella knee brace can be of assistance.

How Do Patella Knee Braces Work?

October 22nd, 2010

A Patella knee brace works by applying a force to the kneecap. The patella has a tendency to drift towards the outside of the knee and this can cause it to rub up against the wall of the groove housing it, causing pain.

Patella knee braces push back against the kneecap, resisting the outwards movement and decreasing the pressure on both the patella and groove wall.

In order to correct this abnormal patella movement, two things have to occur.

Firstly the brace needs to be anchored to the knee to give it a stable base. This is usually done with a combination of straps and the use of non-slip material on the inside of the brace.

Secondly, the brace then levers off this fixed component to apply the corrective force to the patella. If the brace is not stable on the knee the whole thing rotates and no force is applied.

Sizing is important as a patella knee brace that is too big will slip, one too small will be uncomfortable. Each different manufacturer has a different method of determining sizes so read the information carefully.

Some patella braces do not apply a corrective force but just try to resist and further outwards movement of the kneecap. These braces are cheaper and only suitable for very mild cases. They are identified by the lack of strapping going from the outside of the knee across towards the inside. They are also commonly called “Stabilizers” rather than braces.

How Does the Patella Cause Knee Pain?

October 19th, 2010
Patellofemoral Pain Syndrome is also called Anterior Knee Pain. It is a condition that results from abnormal movement of the kneecap when we straighten and bend our knee. It is usually aggravated by activities that involve this movement while we are weight bearing. Climbing or descending stairs is a good example.
The Patella’s job is to protect the quadriceps muscle as it crosses over the knee joint. It moves up and down as we flex our knee and it is contained within a groove at the bottom of the thigh bone. In normal movement the patella glides smoothly and is centered in the groove.
This animation shows the normal movement of the patella in the groove, looking down the thigh from above.

Patella braces push directly on the kneecap, guiding it back towards the inside of the groove and reducing the symptoms of pain and swelling.
Patella knee braces are able to reduce the pressure straight away and with each step causing less aggravation, the pain begins to fade. It is important to use them as part of the complete program with Physical Therapy vital for long term results. In severe cases, when people find the prescribed exercises painful, a brace can help you get started by allowing you to complete your exercise program without stirring up your knee.
