After a conventional implant for Total Knee Replacement, a person can typically walk comfortably and his knee joint will have a good range ofmotion. However, sitting cross-legged and squatting is not advised. If a person opts for a Hi-Flex knee implant, the range of motion of the kneeis better allowing him to sit cross-legged. We would generally suggestthat you do not squat as it is based on individual muscle strength andfitness level. Your doctor will advise you on the activities that you will be able to do comfortably.
