ABSTRACT: Background: Total knee arthroplasty (TKA) is a useful treatment option
for advanced knee osteoarthritis. Excellent clinical outcomes after TKA have
been widely recognized, but the influence of psychiatric problems on them has
not been focused on until quite recently. This study aimed to assess the
influence of psychiatric problems on clinical outcomes after TKA in Japanese
patients using two assessment scales developed in Japan because the Japanese
cultural lifestyle is specifically characterized by bending to the floor and
standing up. Methods: Clinical outcomes and psychiatric problems were evaluated
using the Japanese Knee Osteoarthritis Measure (JKOM) and Brief Scale for
Psychiatric Problems in Orthopaedic Patients (BS-POP), respectively. A total of
115 TKA patients were evaluated preoperatively and at 3, 6, and 12 months after
TKA. The patients were classified into four groups (groups A-D) based
on the BS-POP score. The JKOM scores were then compared between the two groups
(groups A and D) with the worst and least psychiatric problems. The JKOM
improvement rate between pre- and postoperative status in both groups A and D
was also calculated. Results: The total JKOM score was significantly poorer in
group A than in group D preoperatively and at 3, 6, and 12 months after TKA.
The improvement rate showed no significant difference between groups A and D.
Conclusion: Psychiatric problems influence both the poorer post- and
preoperative clinical outcomes. However, a similar improvement rate in both
groups A and D has indicated that TKA can be an effective treatment even for
patients with psychiatric problems.
