Knee Brace Selection for Osteoarthritis
Order a Knee Brace with Hinged Bars in the appropriate size for this patient with knee osteoarthritis requiring support. 1
Rationale for Hinged Brace Selection
Tibiofemoral knee braces with hinges are strongly recommended by the American College of Rheumatology/Arthritis Foundation for patients with knee OA causing significant impact on ambulation, joint stability, or pain. 1 The hinged design provides superior biomechanical benefits compared to simpler options:
Why Hinged Bars Over Other Options:
Hinged braces with rigid uprights provide joint stabilization, load redistribution, and enhanced proprioception that simple sleeves or flexible stays cannot achieve 1
Hinged braces reduce medial compartment loading by 11-17% (most common OA pattern) and can increase joint space width by 1.2mm during gait 1
Hinged designs demonstrate superior pain reduction and functional improvement compared to neoprene sleeves or medical treatment alone at 6-month follow-up (WOMAC scores, pain during walking) 1, 2, 3
Double-upright hinged braces offer maximum stability for patients needing significant support, though single-upright designs provide adequate benefit with better cosmesis and compliance 1
Why NOT the Other Options:
Flex Stays braces lack the rigid structural support needed for meaningful load redistribution and joint stabilization in established OA 1
Horseshoe Support Pad braces are primarily designed for patellofemoral OA, not general tibiofemoral OA requiring overall knee support 1
Simple knee sleeves (if "Knee Brace" without specification means a basic sleeve) provide only proprioceptive benefits and mild pain relief, but are inferior to hinged braces for moderate OA requiring support 1, 2
Sizing Considerations
Measure the patient's thigh circumference 6 inches above the patella and calf circumference at its widest point to determine correct size (Small/Medium/Large/XL) 1
Critical Fitting Points:
Proper fit is essential for efficacy - obesity can interfere with appropriate brace fitting and reduce effectiveness 1
Modern hinged braces incorporate adjustable straps and gel pads to improve comfort over femoral condyles and enhance compliance 1
Patients with reduced grip strength may benefit from braces with restraint systems and easy-adjust buckles 1
Expected Outcomes
Patients wearing hinged knee braces demonstrate:
- Significant pain reduction even in moderate-to-severe OA 1
- Improved WOMAC scores and physical function at 6-month follow-up 1, 2
- Enhanced balance and stability (both static and dynamic) 4
- Reduced NSAID consumption when combined with other interventions 2
Common Pitfalls to Avoid
Do not prescribe without ensuring patient can tolerate the inconvenience - hinged braces are bulkier than sleeves and require commitment to wear 1
Avoid over-tightening straps - while strap tension matters, hinge angle adjustment has greater effect on load reduction than excessive strap tension 1
Do not use if tri-compartmental OA is present - realignment braces work best for unicompartmental disease (typically medial) 1
Ensure follow-up for adjustment - optimal benefit requires proper fitting expertise and potential adjustments after initial use 1
