Donjoy Patelax Elastic Patella Knee Support
An old knee injury or a condition such as arthritis can cause chronic instability and improper patella tracking, resulting in pain and increased difficulty walking. To put knee instability on hold, the Donjoy Patelax Elastic Patella Knee Support features flexible stays that prevent the kneecap from sliding, while a massaging patella pad aids with pain and proprioception.
What's Included?
Please note that this knee brace can be worn on either the left or right leg.
Which Size Is Right For Me?
The Donjoy Patelax Knee Brace comes in seven different sizes. To find the size that will provide the best fit, measure the circumference of your thigh 15cm above the patella, as indicated in the image below. Once you have your measurement, use the sizing chart to find your size.
Measure from 15cm above the mid-kneecap as shown
| Size | Thigh Circumference |

| Small (Size 2) | 39 - 42cm |
| Medium (Size 3) | 43 - 46cm |

Sizing Tips
- If you fall between two sizes, we recommend choosing the larger size to ensure greater comfort
- Due to the compressive nature of this brace, it may feel quite tight; if you would prefer less tightness, please choose a larger size
- If you do not own a flexible tape measure, use a piece of string instead, then measure the string with a ruler
- If your joints swell, please take this into account when choosing your size
What Conditions Can the Donjoy Patelax Be Used For?
Fitted with an adjustable patella strap and flexible bilateral stays, the Donjoy Patelax is designed specifically for injuries and conditions that affect the patella (kneecap). These conditions include the following:
- Osgood-Schlatter disease
- Patellofemoral pain syndrome
- Patellar tendonitis
- Patellar maltracking
Key Features and Benefits
- Anatomical 3D knit design provides targeted compression to a medical standard (20 - 36mmHg)
- Patella kneepad is contoured anatomically to stabilise and massage the kneecap
- Adjustable strap beneath the patella helps relieve pain and tension as you see fit
- Flexible bilateral stays provide medial and lateral support of the knee
- Stretch zones and breathable fabrics ensure optimal comfort and movement freedom
- Compression-reduced edges divert pressure away from the ends for greater comfort
- Non-slip silicone bands ensure a secure hold
How Does the Donjoy Patelax Support the Patella?
The Donjoy Patelax Knee Support incorporates a number of features that strategically counteract maltracking and instability. This includes a contoured patella pad that sits atop the patella to hold it in place, while also providing a gentle massage to boost proprioception. This pad works in conjunction with the two bilateral stays that run either side of the knee to prevent the kneecap from drifting.
Can I Adjust the Level of Support?
Depending on how unstable your knee is, you may wish to alter the level of support to match the severity of your condition. If your knee feels more unstable than usual, tighten the strap around your knee for greater protection. Then when it starts to feel better, loosen the strap to allow for greater comfort and flexibility.
How Comfortable Is this Brace?
A knee brace is most effective when worn for long periods at a time, but this isn't very appealing if it feels cramped and uncomfortable. Thankfully, this isn't the case with the Donjoy Patelax, as it has been made with premium fabrics that let the skin breathe, while two stretch zones allow natural movement.
