A Comparative Effectiveness Study for Non-Operative Treatment Methods for Knee Osteoarthritis

Area of Science:

• Orthopedics
• Rehabilitation Medicine
• Biomedical Engineering

Background:

• Non-operative treatments are common for knee osteoarthritis (OA) when surgery is not indicated.
• Limited comparative data exists for these conservative knee OA treatment options.
• Informing patients and providers on treatment effectiveness is crucial.

Purpose of the Study:

• To compare the effectiveness of home exercise programs versus knee bracing for knee OA.
• To evaluate objective and subjective functional outcomes, pain, and patient metrics.
• To assess the progression to total knee arthroplasty (TKA) over 12 weeks.

Main Methods:

• A comparative study involving brace-only, exercise-only, and combined treatment cohorts.
• Objective measures included quadriceps strength, Self-Paced Walk Test (SPWT), and Timed "Up & Go" (TUG) Test.
• Subjective measures included Lower Extremity Function Scale (LEFS), VR-12, and Visual Analog Scale (VAS-10) for pain.

Main Results:

• All groups showed significant improvements in function and pain from baseline.
• The brace-only group demonstrated a significantly larger improvement in pain scores compared to the exercise-only group (p = 0.022).
• No significant differences were found in objective or subjective functional measures between groups.

Conclusions:

• Knee bracing may be more efficacious for pain reduction than exercise alone in knee OA patients.
• Both treatment options can improve quality of life and delay the need for TKA.
• Larger studies are warranted to confirm the superior efficacy of bracing for knee OA pain.
