Brief Summary

Osteoarthritis (OA) is one of the commonest chronic degenerative conditions affecting our aging population. It limits joint movement and causing disability in elderlies due to discordant symptoms such as pain and stiffness. The prevalence of radiologic knee osteoarthritis increases in proportion to age, reaching an astounding 64.1% for patients whom are over 60 years of age. In addition the prevalence of symptomatic knee OA has been shown to be around 10% in people who are 60 years and older.

Outcome Measures

Primary Outcomes (5)

  • Knee Flexion/Extension Strength

    Muscle strength on the quadriceps is measured by instructing the patient to perform an active knee flexion/extension movement in a sitting position with both feet free from ground, and the hip and knee joint flexed at 90%. The optimal isometric force of the knee flexion/extension movement are measured by the dynamometer attached at the malleoli level with a strap. The measurements (0 to 30 cm) will be taken at maximum force for three times.

    Baseline Assessment

  • Knee Flexion/Extension Strength

    Muscle strength on the quadriceps is measured by instructing the patient to perform an active knee flexion/extension movement in a sitting position with both feet free from ground, and the hip and knee joint flexed at 90%. The optimal isometric force of the knee flexion/extension movement are measured by the dynamometer attached at the malleoli level with a strap. The measurements (0 to 30 cm) will be taken at maximum force for three times.

    Pre-Operative Assessment

  • Knee Flexion/Extension Strength

    Muscle strength on the quadriceps is measured by instructing the patient to perform an active knee flexion/extension movement in a sitting position with both feet free from ground, and the hip and knee joint flexed at 90%. The optimal isometric force of the knee flexion/extension movement are measured by the dynamometer attached at the malleoli level with a strap. The measurements (0 to 30 cm) will be taken at maximum force for three times.

    Post-Operative 6 weeks

  • Knee Flexion/Extension Strength
