In India, the prevalence of the knee joint pain is 31.8%. Objectives: 1. To assess the level of Knee joint pain before application of camphor oil in experimental & control group among elderly. 2.To assess the level of knee joint pain after application of camphor oil in experimental and control group among elderly. 3.To compare the pretest and post-test level of knee joint pain among elderly. 4.To compare the experimental and control group post-test level of knee joint pain among elderly. Methods: Quantitative research approach and a quasi-experimental control group pre and posttest research design were adopted for this study. The study was conducted in selected old age home of Sangli- Miraj- Kupwad Corporation area. The sample size for the study was 40 elderly (20 in experimental group and 20 in control group).

Data collection was done by using demographic variables, pain scale for level of knee joint pain. Results: In the present study it was found that after intervention of camphor oil there was significant difference in experimental group i.e., p value was 0.001. The result shows that there was significant difference between pretest and post-test pain score on level of knee joint pain in experimental and control group. The obtained ‗t value of level of knee joint pain was 4.6 respectively with 48 degrees of freedom which was greater than the table value and it is evident that the camphor oil is significantly effective in reducing the knee joint pain among elderly.
