The Satisfied Total Knee Replacement Patient: 3-Year Multicenter Results

Studies have shown that as many as 1 in 5 total knee replacement (TKR) recipients are dissatisfied with the outcome of their surgery. There has also been a large reported disparity between surgeon and patient perception of clinical “success”. It has long been shown that surgeon opinion of procedural outcomes is inflated when compared with patient-reported outcomes. Additionally, TKR recipients have consistently reported higher pain levels, greater inhibition of function, and lower satisfaction than total hip replacement recipients. It is imperative that alternative methods be explored with which to improve TKR patient satisfaction. Therefore, the purpose of this prospective multicenter study was to report 3-year patient satisfaction levels following TKR with the use of intraoperative sensors to aid in soft tissue balancing, and to compare these satisfaction results with previous studies of which utilized other surgical modalities.
