Physiotherapy: Knee Age Calculator

Your chronological age is the age on your birth certificate. Your knee age is the age your knees are actually functioning at — and for millions of Indians, these two numbers are a decade or more apart. Chronic knee pain, cartilage wear, reduced range of motion, and muscle imbalance around the joint all accelerate the biological ageing of the knee. Left unaddressed, what begins as occasional discomfort becomes structural degeneration that eventually requires surgical intervention.

This calculator assesses your functional knee age using clinical markers: pain on movement, stiffness duration, crepitus, quadriceps strength, and daily activity limitation. It tells you whether your knees are ageing ahead of schedule — and by how much. More importantly, it identifies the modifiable factors driving that accelerated ageing. The right physiotherapy protocol, combined with targeted strengthening and weight management, can genuinely reverse functional knee age — not just mask the pain.
