Clinical Scorecard: Knee OA Pain: Inulin vs Physiotherapy Effects

At a Glance

Key Highlights

• Both inulin supplementation and physiotherapy-supported exercise reduced knee OA pain over 6 weeks, each exceeding the minimum clinically important difference on the Numerical Rating Scale.
• Physiotherapy improved physical function (sit-to-stand and timed up-and-go tests), while inulin improved grip strength and increased pressure pain thresholds.
• No synergistic pain reduction was observed when combining inulin with physiotherapy; dropout rates were lower with inulin than physiotherapy.

Guideline-Based Recommendations

Diagnosis

• Use Numerical Rating Scale to assess baseline and changes in knee OA pain.

Management

• Consider inulin supplementation as a dietary intervention to reduce pain and improve grip strength in knee OA patients.
• Implement physiotherapy-supported exercise programs to reduce pain and improve physical function.
• Combined use of inulin and physiotherapy does not provide additional synergistic pain relief.

Monitoring & Follow-up

• Monitor pain changes using Numerical Rating Scale.
• Assess physical function improvements via sit-to-stand and timed up-and-go tests.
• Observe for minor gastrointestinal adverse events with inulin supplementation.

Risks

• Minor gastrointestinal adverse events may occur with inulin but do not typically lead to treatment discontinuation.
• Higher dropout rates observed in physiotherapy-supported exercise groups.

Patient & Prescribing Data

Community-dwelling adults with knee osteoarthritis

Inulin is well tolerated with low dropout rates and improves pain and grip strength; physiotherapy improves pain and functional mobility but has higher dropout rates.

Clinical Best Practices

• Use a 6-week intervention period to evaluate pain and functional outcomes.
• Adjust analyses for baseline values and consider intention-to-treat approaches with imputation for missing data.
• Educate patients on potential minor gastrointestinal effects of inulin to improve adherence.
• Recognize that physiotherapy requires patient engagement and may have higher dropout rates.
• Consider integrating dietary interventions like inulin alongside physiotherapy for a holistic approach to knee OA management.
