Abstract

Background For some time, mental illness has had a significant impact on how total knee arthroplasty results are evaluated.Mental illness diagnoses are associated with higher medical treatment costs, longer recovery times, and hospital stays, in addition to other patient-related factors.This paper compares and contrasts how mental illness and the general population influence surgical outcomes.The experimental group in our hospital's retrospective study, which ran from June 2020 to January 2022, consisted of patients with mental illnesses like schizophrenia, bipolar disorder, depression, and substance abuse. The control group consisted of patients who had total knee arthroplasty but did not have a mental illness.During the study, postoperative complications and length of stay were also recorded.From June 2020 to January 2022, 634 patients underwent total knee arthroplasty at our clinic, 239 of whom had mental illness.As outcome measures, the Knee Society Score (KSS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were utilized.The majority of patients, 61 percent, were female, and the average length of stay for mental illness patients was significantly longer (6.8 days versus 2.8 days).Preoperative WOMAC and KS function scores (67.83 17.8 versus 62.75 15.7 and 29.31 19.8 versus 34) showed statistically significant differences between the groups. On all postoperative functional scores, the control group performed significantly better than the mental illness group.Lower TKA scores appear to be linked to mental illness before and after surgery.
