prevalence of knee pain in the population is approximately 19%. The incidence
increases steadily with age. It is estimated that the overall prevalence
of knee pain for men of all ages is between 15% and 20%. A study in the US
showed that approximately 18% of men aged 60 years or more reported knee pain and increases steadily with age. The incidence of knee
pain has been found to be slightly more common in females compared to men approximating to 20%. A study in the
US showed that approximately 23% of women aged 60 years or more reported knee
pain. Knee pain,
particularly chronic knee pain is less common in children due to reduced
incidence of degenerative joint disease. The total prevalence of chronic knee
pain in adolescents is around 18% compared to approximately 4% in children.

between boys and girls in these age groups. This very common conditions are treated using Analgesics, Postural Care, Electro-therapy and Exercise-therapy mainly.
