Knee Brace Use in Patellofemoral Pain Syndrome
Use the knee brace as a temporary adjunct only while prioritizing quadriceps and hip strengthening exercises, which are the definitive treatment for patellofemoral pain syndrome. 1, 2
Primary Treatment Approach
The most effective treatment is a structured physiotherapy program combining quadriceps strengthening, hip abductor strengthening, and quadriceps stretching. 2, 3 This approach has the strongest evidence for reducing pain and improving function in patellofemoral pain syndrome, while bracing alone shows inconsistent objective benefits despite patient-reported symptom relief. 1
Role of Bracing
When to Use the Brace
- Use the patellofemoral brace as a short-term adjunct during the initial rehabilitation phase to provide symptom relief while the patient builds strength. 4, 5
- The brace may help during activities that provoke symptoms while the underlying muscle dysfunction is being corrected. 1
Critical Limitations of Bracing
- Patients consistently report subjective improvements that exceed objective findings, meaning the brace provides perceived benefit without measurable mechanical correction. 1, 4
- Evidence supporting brace effectiveness is weak and lacks well-controlled studies. 1, 6
- Lower extremity muscle strengthening, flexibility improvements, and activity modification are more important than bracing. 1
Rehabilitation Protocol to Emphasize
Strengthening Program
- Begin quadriceps strengthening immediately, focusing on both general quadriceps and hip abductor exercises. 2, 3
- Progress from isometric to concentric and eccentric exercises as pain allows. 7
- Closed kinetic chain exercises should be prioritized to reduce patellofemoral pain risk. 7
Load Management
- Modify activities that increase pain, particularly those involving knee flexion under load. 3
- Educate the patient about avoiding overuse and trauma that perpetuate symptoms. 3
Adjunctive Therapies
- Consider patellar taping or orthotics as additional adjuncts, though these show limited benefit when used alone. 2, 6
- Do not rely on the brace to provide actual joint protection—it may create a false sense of security without protective benefit. 7
Common Pitfalls to Avoid
- Do not allow long-term brace dependence without addressing the underlying muscle weakness and biomechanical dysfunction. 4, 8
- Avoid using the brace as the primary treatment modality; it should never replace a comprehensive strengthening program. 1, 2
- Do not continue bracing indefinitely based solely on patient preference when the evidence doesn't support long-term benefit. 8
- Ensure proper brace fitting if used: measure leg circumference 3 inches above and below mid-patella, position the lateral buttress correctly, and check periodically for migration. 1, 4
Clinical Algorithm
- Initiate structured physiotherapy immediately with quadriceps and hip strengthening as the primary intervention. 2, 3
- Allow brace use during symptomatic activities in the initial 4-8 weeks while strength is being built. 4, 5
- Progressively wean the brace as muscle strength improves and symptoms decrease. 1
- Discontinue the brace entirely once adequate strength is achieved and symptoms are controlled through proper biomechanics. 7, 8
