1. Product Overview
The DonJoy Lateral J Patella Knee Brace is designed to provide support for individuals experiencing lateral patellofemoral knee pain. This includes conditions such as lateral patellar subluxation and dislocations, lateral patellofemoral malalignment, patellofemoral maltracking, and chondromalacia. It is suitable for daily activities and sports, both in and out of water.
The brace features a tubular, lateral "J" buttress positioned alongside the knee. Users can select between Drytex and neoprene material options, and with or without aluminum hinges for enhanced stability.
- Drytex Material: Offers improved airflow and is recommended for warm climates or individuals with neoprene allergies/irritations.
- Neoprene Material: A thicker, wetsuit-like material providing substantial support, compression, and warmth.
- Aluminum Hinges: Provide additional stability and confidence during movement.
The design is universal, accommodating both men and women.

2. Sizing and Fitting Instructions
Accurate measurement is crucial for proper fit and effectiveness of the DonJoy knee brace. Follow these steps to determine your correct size:
- Stand with your legs shoulder-width apart, slightly bent, and leg muscles contracted.
- Measure the circumference of your leg at the midpoint of your kneecap.
- Measure 6 inches (approximately 15 cm) up from the center of your kneecap. At this 6-inch mark, measure the circumference of your thigh.
- Measure 6 inches (approximately 15 cm) down from the center of your kneecap. At this 6-inch mark, measure the circumference of your calf.
Once you have these three measurements, refer to the sizing chart below to find the corresponding DonJoy knee brace size.

3. Operating Instructions
Once the correct size is determined and the brace is received, follow these general steps for application:
- Ensure your leg is clean and dry before applying the brace.
- Position the brace so the "J" buttress aligns with the lateral (outer) side of your kneecap.
- Secure the straps, starting with the strap directly above the kneecap, then below, and finally the thigh and calf straps. Adjust for a snug, comfortable fit that provides support without restricting circulation.
- Move your knee through its range of motion to ensure the brace stays in place and does not cause discomfort. Readjust straps as necessary.
For specific application details, refer to any diagrams or instructions included with your product packaging.
4. Maintenance
Proper care will extend the life of your DonJoy knee brace:
- Hand wash with mild soap in cold water.
- Rinse thoroughly and air dry.
- Do not machine wash, tumble dry, iron, or bleach.
- Avoid exposure to direct heat or sunlight for prolonged periods.
- Inspect the brace regularly for wear and tear, especially on straps and hinges. Replace if significant damage is observed.
5. Troubleshooting
If you encounter issues with your knee brace, consider the following:
- Discomfort or pinching: Re-evaluate your measurements and ensure the brace size is correct. Adjust straps to be snug but not overly tight. Ensure the buttress is correctly positioned.
- Brace slipping: Ensure all straps are securely fastened. If the brace continues to slip, re-check your measurements against the sizing chart. Muscle contraction during measurement is important.
- Lack of support: Verify that the brace is correctly aligned with your kneecap and that the straps are tightened appropriately. If you have a hinged model, ensure the hinges are functioning correctly.
If problems persist, consult with a healthcare professional or contact DonJoy customer support.
