Total joint replacements today allow much better range of motion at the hip than needed for most activities of daily living. Most patients do not need range of motion more than 90 degrees after hip replacement surgery. A 90-degree motion at the knee and 90-degree motion at the hip are enough for patients to carry on their activities of daily living including walking up and down stairs, including sitting on chairs and sitting on a toilet seat. Patients need about 20 degrees internal and external range of motion for activities of daily living. Today’s implants allow much better range of motion.
