Objective: The study was done to assess the balance function in elderly with knee osteoarthritis along with quadriceps strength and prprioceptive acuity (joint position sense). Methods: The study was observational type with 30 subjects in group 1 with osteoarthritis knee and 30 subjects in group 2 without any known history of osteoarthritis of knee joint. The subjects were measured for quadriceps strength, prprioceptive acuity, static balance using mCTSIB and functional balance using timed Up and Go test. The test scores were compared using student’s t test. Results:The study showed a statistically significant difference for all the variables studied such as quadriceps strength, prpioceptive acuity (joint position sense), modified CTSIB score and TUG scores between the groups. Conclusion: The elderly adults with knee osteoarthritis have deterioration in quadriceps strength, proprioceptive acuity, static balance and functional mobility.
