Striving for a silent knee: a qualitative study of patients' experiences with knee replacement surgery and their perceptions of fulfilled expectations

Purpose: Fifteen to twenty percent of patients with a knee arthroplasty are dissatisfied with their replaced joint. This study aimed to describe patients' experiences of undergoing knee replacement surgery, both total- and unicompartmental knee replacement, and post-operative recovery, and to determine whether expectations of surgery were fulfilled. Methods: Using semi-structured interviews, this study describes twelve patients' experiences of undergoing knee replacement surgery in the prior year, their post-operative recovery, and whether their expectations of surgery were fulfilled. Qualitative thematic analysis was used. Results: A theme "striving for a silent knee", and two categories "the bumpy road to recovery" and "the presence of the future" were created. Some participants were not fully restored one year after surgery. Those still in pain had thoughts about the future, from hoping to improve, to accepting living with an aching knee. Those with no pain, did not think about their knee-the knee had become silent. Conclusions: Surgeons often inform patients that the recovery time after a knee arthroplasty is one year, which in light of this study, might be too short. We suggest that a follow-up after one year might identify those who need enhanced physical and psychological support to get the best possible outcome, whether it is to help patients accepting persistent symptoms or to continue striving towards a silent knee.
