Abstract : Background: Total knee replacement (TKR) is one of the most popular surgical procedures performed on patients with severe knee arthritis, and knee extension lag is a common complication. Extension Lag is the inability to extend the knee to the final 15 degrees of extension. The study's goal is to investigate and compare the effectiveness of a six-week open and closed kinetic chain exercise on pain and range of motion in people with knee extension lag after TKR.  Study Design: Comparative Study.  Methods: In a 6-week intervention study, 30 older individuals underwent total knee replacement. The subjects were divided into two groups: Group A received Open Kinetic Chain Exercises, and Group B received Close Kinetic Chain Exercises, with Conventional Exercise remaining the same for both groups for 6 weeks. The Universal Goniometer is used to quantify knee range of motion, while the Visual Analogue Scale is used to assess discomfort. Pre- and post-treatment data were gathered and analysed using SPSS 22.0. The Paired T-Test was used to determine the significance of the treatment.  Results: Close Kinetic Chain Exercise Can Be Used alongside a Conventional Exercise Program to effectively manage individuals with Extension Lag Post Total Knee Replacement in terms of pain reduction and correction. Group B showed greater pain reduction (P < 0.05) than Group A after treatment.  Conclusion: The study concluded that the treatment plan used by Group B, Close Kinetic Chain Exercise with Conservative Exercise, is more successful in minimising Extension lag in post-total knee replacement patients than Group A, Open Kinetic Chain Exercise with Conservative Exercise.
