AIM Range of motion prior to TKRis a key determinant of the post-operative range of motion.The likelihood that the accompanying stiffness of the extensor mechanism will result in limited flexion following surgery increases with the preoperative range of motion.It would make sense to enhance knee ROM before surgery in order to optimize flexion following TKA.Comparisons were made between the patient groups who had knee surgery with preoperative exercises and those who had surgery without them. METHODS 156 patients with knee arthritis were collected over a period of 1.5years. They were divided into two groups. Pre-operative knee exercise was given to 78 patients for aone month. Prior to and following the test group's workouts, all patients were observed.All 156 underwent TKR, and their post-operative range of motion was evaluated at four weeks, three months, six months, and a year. We timed how long it took to fully extend and flex to 90 degrees. RESULTS Thisstudy suggested that the knee workouts were unquestionably helpful in achieving early knee flexion up to 90 in comparison to that of the control group. When the test group was compared to the control group, knee flexion to about 90 and more was attained in about 4 weeks; this difference was statistically significant (p 0.01).But after six months and a year of long-term follow-up, there were no discernible changes in the knee's range of motion. CONCLUSION Prehabilitation significantly improves the Knee Score for the intervention group both before surgery and three months after surgery. Exercises done before to surgery help patients recover more quickly from TKA and may speed up the process of achieving a good flexion and extension range of motion. However there is no significant difference in functional outcome after one year post surgery in both groups.
