Background: The number of patients who undergo total knee replacements (TKR) is on the rise, and with that rise comes higher patient expectations and higher functional needs. As a result of the declining average age at which orthopaedic surgeons may recommend TKR, patients frequently have the expectation that they will be able to return to sport (RTS) after TKR. The purpose of this research was to investigate the mid-term RTS, satisfaction level, forgotten joint level, and recreational activities after total knee replacement surgery (TKR).
