Abstract
knee instability is associated with activity limitations in patients with knee osteoarthritis (OA), in addition to knee pain and muscle strength. Aims & Objective: "To study the prevalence of self-reported knee Instability to physical-function in patients with knee Osteoarthritis. Method: 50 subjects diagnosed with osteoarthritis knee were included in the study. Functional status of patient was evaluated using WOMAC index scale. The data was collected by questionnaire form and was analyzed using SPSS 14.0 and graph pad 6.7 version. Correlation of Physical Function, Stiffness, Pain and Get up and Go test was done using Pearson correlation coefficient. Result: 28% of cases were in the age group between 40-50 years and 20% were more than 50-60 years. 30% was between 60-70 and 22% were above 70 years. The correlation between the Principal component score for physical function & age is non-significant with P value 0.226. The correlation between the Principal component score for physical function & sex is significant with P value <0.001, The correlation between the Principal component score for physical function & pain is significant with P value 0.025,The correlation between the Principal component score for physical function & no. of years diagnosed as knee OA is significant with P value <0.00). The correlation between the principal component score for physical function & knee range of motion is significant with P value 0.0003 for flexion and 0.0137 for extension. The correlation between the Principal component function & Quadriceps torque is significant. o score for physical with a P value <0.001 The correlation between the Principal component score for physical function & ADL score is significant with P value <0.00°1 Conclusion: From the present study it is concluded that the result indicates that individuals with knee osteoarthritis report, episodes of knee instability during activities of daily living. Instability affects physical function which can be explained by contributions from other impairments such as knee pain, range of motion and quadriceps strength.
