Description
One of the unsolved problems of total knee arthroplasty (TKA) is the occurrence of postoperative sound or crepitus from the knee. Some patients express their concerns about a sound or rattling sensation around the knee after TKA.
The purposes of this study are
1) to investigate the prevalence of sounds around the knee over time after primary TKA;
2) to identify factors influencing postoperative sound; and
3) to assess whether sound after TKA affects clinical outcomes.
