After six months of total knee replacement surgery, the patient is expected to be performing all daily activities, such as driving, shopping, and cooking, and to be nearly normal in society. This calls for multitasking, ambulating in crowded locations, and having adequate lower limb function. Functional recovery is important to be able to perform daily activities as well as participate in a community. Fear of Fall can affect this ability. Therefore, this study aims to find Correlation of Fear of Fall with Balance and Pain in patients with bilateral total knee arthroplasty post 6 months. 30 participants will be selected based on the inclusion and exclusion criteria. Informed consent will be taken and if they agree to participate in this study, they will be included in the study. A one-time assessment of 15-20 minutes will be performed. They will be asked about their demographic data (name, age, etc.). Their Fear of Fall will be assessed using Fall Efficacy Scale International. It has 16 Questions where each question has 4 possible responses: 1-not at all concerned; 2-somewhat concerned; 3-fairly concerned; 4-very concerned. They will be asked to mark an option that is appropriate for them. Next, the Timed Up and Go (TUG) test will be taken. In this, the participant will sit in the chair with their back against the chair back. On the command “go”, he/she will rise form the chair, walk 3 meters at a comfortable and safe pace, turn, walk back to the chair and sit down. Timing will begin at the instruction “go’ and stop when they are seated. They will have one practice trial that is not included in the score. Then Pain will be assessed using Visual Analogue Scale, in this a 10 cm line will be drawn and patient will be asked to mark a point between 2 endpoints (No pain at all and Worst Possible pain) and The distance between ‘no pain at all’ and the mark then defines the patient’s pain. Once all the data has been collected, it will be analyzed using the statistical tests. Depending upon the normality of the data, Pearson’s or Spearman’s coefficient will be calculated.
