Why GenuForce Design for Patellar Tracking and Stability

The GenuForce knee brace addresses the common challenge of patellar maltracking (kneecap misalignment during knee movement), which causes anterior knee pain, instability, and decreased function. The silicone patellar ring gently guides the patella into proper alignment during flexion and extension, distributing forces evenly across the patellofemoral joint to reduce localized pressure that causes pain. The bilateral flexible spiral stays provide medial-lateral (side-to-side) stability without restricting natural knee flexion-extension, making this brace suitable for both daily activities and light-to-moderate sports. The compression knit construction delivers circumferential support that reduces swelling and provides proprioceptive feedback (enhanced joint position awareness), helping users move with confidence. This combination of patellar guidance, lateral stability, and compression addresses the multi-factorial nature of common knee conditions like patellofemoral pain syndrome, chondromalacia patella, and mild ligament strain.

Usage & Application

Understanding Knee Brace Types

Knee braces serve different purposes and provide varying levels of support:

Compression Sleeves:

• Basic compression without structural support
• For mild swelling, warmth, and comfort
• No patellar guidance or stability features
• Suitable for very mild issues

Patellar Stabilization Braces (GenuForce - This Product):

• Compression PLUS patellar ring for tracking
• Bilateral stays for medial-lateral stability
• For patellofemoral problems, mild instability
• Suitable for moderate activity levels
• Balance of support and mobility

Hinged Knee Braces:

• Rigid hinges restrict/control motion
• For significant ligament injuries (ACL, MCL, LCL)
• Post-surgical support
• More restrictive than GenuForce

Post-Operative Braces:

• Maximum immobilization after surgery
• Range-of-motion control
• Temporary use during healing

GenuForce Positioning: Mid-level support between basic compression and rigid hinged braces—ideal for users needing patellar guidance and stability without full immobilization.

When GenuForce is Appropriate

Ideal Candidates:

• Patellofemoral pain syndrome (anterior knee pain)
• Feeling kneecap "slipping" or "giving way"
• Pain going up/down stairs (patellar stress)
• Pain during squatting or kneeling
• Mild side-to-side instability
• Swelling around kneecap or general knee area
• Post-injury return to activity (mild-moderate injuries)
• Preventive support for at-risk activities

Not Appropriate If:

• Severe ligament tears (need hinged brace)
• Post-surgical immediate period (need rigid brace)
• Open wounds or active infection on knee
• Severe circulatory problems
• Allergy to compression fabrics

Consult healthcare provider if unsure whether GenuForce provides adequate support for your specific condition.

Understanding Size 4+ (Large+)

Proper sizing critical for effectiveness:

DJO GenuForce Sizing: Based on circumference measured around knee center (across mid-patella):

• Size 1 (Small): 12-13 inches (30-33 cm)
• Size 2 (Medium): 13-14.5 inches (33-37 cm)
• Size 3 (Large): 14.5-16 inches (37-41 cm)
• Size 4 (XL): 16-17.5 inches (41-44 cm)
• Size 4+ (Large+/XXL): 17.5-19 inches (44-48 cm) - THIS PRODUCT

Measuring Your Knee:

1. Sit with knee slightly bent (15-20 degrees)
2. Use flexible measuring tape
3. Measure circumference around center of kneecap
4. Measure snugly but don't compress tissue
5. If between sizes, choose larger size for comfort

Signs Size 4+ is Correct:

• Brace fits snugly without excessive tightness
• Patellar ring centers over kneecap
• No bunching or rolling at top or bottom
• Compression feels firm but not painful
• Can wear comfortably for several hours

Signs of Wrong Size:

• Too Small: Excessive tightness, redness, numbness, can't bend knee comfortably
• Too Large: Brace slides down, patellar ring off-center, inadequate compression

Adjacent Sizes:

• Size 4 (XL): If 4+ feels too loose or bunches
• Custom Options: If knee larger than 19 inches, consult DJO for custom solutions

Pre-Application Preparation

Skin Preparation:

1. Clean knee area with soap and water
2. Dry completely (moisture causes irritation under brace)
3. Avoid lotions or oils before application (reduces brace adhesion/grip)
4. Check for open wounds, rashes, or irritation (don't apply over damaged skin)

Optimal Application Timing:

• Morning when swelling minimal (easier application)
• Before activity requiring support
• After showering (clean, dry skin)

First-Time Application Tips:

• Sit in chair for initial fitting
• Have someone assist if difficult to reach
• Take time to position correctly—proper alignment critical for effectiveness
• Expect 2-3 applications to master technique

Applying GenuForce Knee Brace

Step-by-Step Application:

1. Orient brace correctly:
   • Identify silicone patellar ring (should be obvious opening at center front)
   • Locate top vs. bottom (top typically has non-slip silicone band)
   • Note any "top" or directional markings
   • Universal design works on either left or right knee
2. Initial positioning:
   • Sit in chair or on bed edge
   • Extend leg slightly (don't fully straighten)
   • Bunch brace material up like putting on sock
3. Slide brace onto leg:
   • Insert foot through bottom of brace
   • Pull brace up over calf and onto knee
   • Stop when patellar ring approaches kneecap
4. Center patellar ring:
   • CRITICAL STEP: Silicone ring must center precisely over kneecap
   • Look down at knee—kneecap should be visible through ring opening
   • Adjust brace up/down/rotate until perfectly centered
   • Ring should surround kneecap with small clearance gap
5. Position spiral stays:
   • Bilateral stays should be on medial (inside) and lateral (outside) of knee
   • NOT front and back—should be on SIDES
   • Rotate brace if stays positioned incorrectly
6. Final positioning:
   • Pull top edge up to ensure non-slip band sits on thigh (not on knee)
   • Smooth out any wrinkles or bunching
   • Ensure even compression around entire circumference
   • Bottom edge should sit on upper calf, not over calf muscle bulk
7. Check fit:
   • Stand up and bend knee a few times
   • Patellar ring should stay centered during movement
   • Brace should stay in place without sliding down
   • Compression should feel firm but not painful
   • No numbness, tingling, or excessive tightness

Common First-Time Mistakes:

• Patellar ring off-center (too high, too low, or rotated)
• Stays positioned front-back instead of medial-lateral
• Brace upside-down
• Size too small (painful) or too large (slides)

Adjustment Period

Initial Wear: First-time users need adaptation period:

Day 1-2:

• Wear 2-3 hours maximum
• During low-activity periods (watching TV, light household tasks)
• Monitor for redness, irritation, or discomfort
• Remove if any numbness, tingling, or excessive tightness

Day 3-5:

• Increase to 4-6 hours
• Begin wearing during light activities (walking, grocery shopping)
• Continue monitoring skin condition

Week 2+:

• Progress to all-day wear if needed
• Can wear during work, sports, and daily activities
• Take off at night unless instructed otherwise by healthcare provider

Why Gradual Introduction:

• Allows skin to adapt to compression
• Identifies any sizing or fit issues before committing to full-time use
• Reduces risk of skin breakdown from prolonged pressure

Daily Wear Guidelines

When to Wear:

• During activities causing knee pain (walking, stairs, sports)
• Throughout workday if job involves standing, walking, lifting
• Preventively before high-risk activities
• During rehabilitation exercises
• Any time needing knee stability and confidence

When to Remove:

• At night during sleep (unless instructed otherwise)
• During bathing or swimming
• If skin irritation develops
• During complete rest periods
• If excessive swelling develops under brace

Wearing Over Clothing: Can wear over thin leggings or compression pants, but:

• Less effective than direct skin contact
• May reduce proprioceptive benefits
• Patellar ring positioning more difficult
• Consider for modesty in public or during work

Maintaining Function During Wear

Patellar Ring Function: The silicone ring provides gentle guidance:

• During Knee Extension: Ring centers patella in femoral groove
• During Knee Flexion: Ring prevents lateral tracking (outward drift)
• During Weight Bearing: Distributes pressure evenly around kneecap
• Should feel subtle—not restrictive or painful

Spiral Stays Function: Flexible stays prevent unwanted side-to-side motion:

• Flex during normal knee bending/straightening
• Resist when force pushes knee inward (valgus) or outward (varus)
• Provide confidence during cutting motions in sports
• Don't significantly limit range of motion

Compression Benefits: Medical-grade compression provides:

• Reduced swelling through improved fluid drainage
• Enhanced proprioception (joint position sense)
• Warmth improving circulation and comfort
• Support to surrounding muscles and soft tissues

Activity-Specific Guidance

Walking and Stairs:

• GenuForce excellent for these activities
• Patellar ring reduces stair-climbing pain
• Compression reduces swelling from prolonged walking
• Wear consistently during walks if experiencing pain

Running and Sports:

• Suitable for light-to-moderate running
• Good for recreational sports (tennis, basketball, volleyball)
• May not provide enough support for competitive athletics or contact sports
• Consider hinged brace if higher-level activity or more significant instability

Work Activities:

• All-day wear comfortable for most jobs
• Standing occupations: Reduces fatigue and swelling
• Lifting/physical labor: Provides stability confidence
• Seated work: Can wear but remove periodically if causing discomfort

Exercise and Rehabilitation:

• Wear during physical therapy exercises as directed
• Provides support during strengthening activities
• May improve exercise form by enhancing knee stability
• Remove if interferes with specific therapeutic exercises

Monitoring and Troubleshooting

Normal Sensations:

• Mild pressure/snugness (compression)
• Warmth around knee
• Enhanced awareness of knee position
• Mild adjustment period (first few days)

Concerning Symptoms (Remove Immediately):

• Numbness or tingling below knee (circulation compromise)
• Excessive tightness or pain
• Skin discoloration (white, blue, red beyond normal)
• Swelling below brace (calf, ankle, foot)
• Severe itching or rash

Common Issues and Solutions:

Brace Slides Down During Activity:

• Ensure non-slip silicone band positioned on thigh skin (not over clothing)
• May need smaller size if persistently slides
• Shave leg hair if preventing silicone grip
• Consider adhesive spray for extra grip

Patellar Ring Causes Discomfort:

• Verify ring is centered—off-center ring creates pressure points
• May indicate early adaptation—continue gradual wear increase
• If persistent, consult healthcare provider (may need different brace style)

Bunching Behind Knee:

• Common with improper sizing (too large)
• Smooth fabric before sitting
• May need smaller size

Excessive Sweating/Heat:

• Breathable fabric minimizes this, but some moisture normal
• Wash brace more frequently
• Consider wearing thin moisture-wicking sock underneath
• Remove during rest periods to allow skin drying

Red Marks After Removal:

• Mild temporary redness normal (fades within 30 minutes)
• Deep indentations or persistent marks suggest too tight—size up
• Monitor for progression to breakdown

Skin Care and Hygiene

Daily Skin Monitoring:

• Check skin condition after removing brace
• Look for redness, rashes, blisters, or breakdown
• Pay attention to areas under silicone components (friction points)
• Early intervention prevents progression to serious problems

Skin Protection:

• Keep skin clean and dry
• Avoid heavy lotions or oils under brace
• If sensitive skin, consider thin tubular bandage or moisture-wicking sleeve underneath
• Address any irritation before continuing wear

Brace Hygiene:

• Sweat and bacteria accumulate in fabric
• Clean regularly (at least weekly, more if heavy use)
• Odor indicates need for washing
• Clean brace = healthier skin and longer brace life

Care and Cleaning Instructions

Hand Washing (Recommended):

1. Fill sink or basin with lukewarm water
2. Add mild detergent (no bleach, no fabric softener)
3. Submerge brace, gently agitate
4. Let soak 10-15 minutes
5. Rinse thoroughly with clean water until no soap remains
6. Gently squeeze out excess water (don't wring or twist)

Machine Washing (If Necessary):

• Use mesh laundry bag to protect brace
• Cold water, gentle cycle
• Mild detergent only
• Small load or wash alone

Drying:

• Air dry only—NEVER use dryer heat
• Lay flat on towel or hang to dry
• Avoid direct sunlight or heat sources
• Allow complete drying (6-12 hours) before next use
• Heat damages elastic and silicone components permanently

Frequency:

• Heavy use (daily sports, physical job): Wash 2-3 times per week
• Moderate use (daily wear): Wash weekly
• Light use (occasional activities): Wash every 2 weeks or as needed

What to Avoid:

• Bleach (damages elastic and silicone)
• Fabric softener (reduces compression effectiveness)
• Dryer heat (permanently damages brace)
• Dry cleaning chemicals
• Ironing

When to Replace Brace

Signs of Wear Requiring Replacement:

• Loss of elasticity (brace stretched out, doesn't provide compression)
• Tears or holes in fabric
• Silicone components cracked or peeling
• Spiral stays bent or broken
• Non-slip band no longer grips
• Persistent sliding despite correct size
• Generally: 6-12 months with daily use; 1-2 years with occasional use

DJO Quality: DonJoy/DJO braces typically last longer than generic brands due to:

• Higher-quality materials
• Better construction
• More durable silicone components
• Worth the investment for regular users
