Setup and Application
Unpacking
Carefully remove the DonJoy Playmaker Neoprene Knee Brace from its packaging. Inspect the brace for any signs of damage or defects before initial use. Ensure all straps and components are intact.
Applying the Brace
- Prepare the Brace: Unfasten all straps and lay the brace flat. The open back design allows for easy positioning around the knee.
- Position the Brace: Center the brace over your kneecap, ensuring the patella opening (if applicable to your model) is correctly aligned. The hinges on the sides should align with the natural bend of your knee.
- Secure Lower Straps: Begin by securing the lower straps around your calf. Pull them snugly but not too tightly, ensuring blood circulation is not restricted.
- Secure Upper Straps: Next, secure the upper straps around your thigh. Adjust for a firm, comfortable fit that prevents the brace from slipping.
- Final Adjustments: Stand up and gently bend your knee a few times to ensure the brace moves naturally with your leg. Readjust straps as needed to achieve optimal support and comfort without pinching or binding.

Operating Instructions
Adjusting the Brace
The DonJoy Playmaker brace is designed for dynamic support. Throughout the day, you may need to adjust the straps to maintain optimal compression and comfort. If the brace feels too loose or too tight, simply unfasten the hook-and-loop straps and re-secure them to achieve the desired fit. Ensure the brace remains centered on your knee.

Wearing Duration
Wear the brace as recommended by your healthcare professional. For general support during activity, it can be worn for the duration of the activity. For post-injury or post-operative use, follow specific medical advice regarding wearing schedule and duration. Always remove the brace if you experience increased pain, numbness, tingling, or discoloration of the skin.
Maintenance and Care
Cleaning Instructions
- Hand Wash Only: It is recommended to hand wash the brace in cold water with mild soap.
- Rinse Thoroughly: Rinse the brace thoroughly to remove all soap residue.
- Air Dry: Lay flat or hang to air dry. Do not use a washing machine or dryer, as this can damage the neoprene material and structural components.
- Avoid Bleach and Harsh Detergents: Do not use bleach, fabric softeners, or harsh detergents, as these can degrade the material.
Storage
Store the brace in a cool, dry place away from direct sunlight and extreme temperatures. Ensure the hook-and-loop fasteners are secured to prevent them from attracting lint or damaging other fabrics.
Troubleshooting
- Brace is Slipping: Ensure all straps are tightened appropriately. Re-check your measurements against the sizing chart to confirm you have the correct size.
- Discomfort or Pinching: Loosen the straps slightly. Adjust the brace's position on your knee. Ensure no fabric is bunched up. If discomfort persists, consult a healthcare professional.
- Skin Irritation: Ensure the brace is clean. If irritation occurs, try wearing a thin, breathable sleeve underneath the brace. Discontinue use and consult a healthcare professional if irritation worsens or persists.
- Hinge Malfunction: Inspect the hinges for any debris or damage. If a hinge appears broken or is not functioning smoothly, discontinue use and contact customer support.
