Aim of this study is to assess the psychometric properties of the
developed Greek version of the Knee Injury and Osteoarthritis Outcome Score
(KOOS) in total knee replacement (TKR) patients. METHODS: Psychometric properties
of the Greek version of KOOS were evaluated according to the Consensus-based
Standards Measurements Instruments (COSMIN) checklist. Patients' pre-operative
clinical status and post-operative outcomes at two occasions (at discharge and
10-12 days post-operatively) were evaluated using the KOOS, KOS-ADL and SF-12
Health Survey. RESULTS: A comprehensive Greek KOOS was piloted and well accepted
by patients and therefore administered to 60 consecutive TKR patients (mean age
72.2 +/- 7.2 years, 39 women). Excellent Internal consistency, good test-retest
reliability of KOOS and KOOS 5 subdomains, respectively [ICC(2-1) 0.76, 95% CI =
0.235-0.902 and 0.89, 95% CI = 0.843-0.927] was yielded. A priori hypotheses for
construct validity were confirmed with KOOS score and subdomains for pain,
symptoms and Everyday Living function (ADL) correlating moderately with KOS-ADL.
Responsiveness for KOOS subdomains of Pain and Symptoms yielded moderate effect
size (ES = 0.4). CONCLUSION: The Greek KOOS was found to be a practical and
comprehensible self-reported measure for TKR patients with acceptable
psychometric properties. It is therefore, recommendable for usage in future
clinical trials and clinical practice. Implications for Rehabilitation The Greek
version of KOOS is an essential assessment scale to evaluate not only acute
injuries but also chronic knee associated conditions in a holistic perspective.
The Greek KOOS has been found to be a practical and comprehensible self-reported
measure for TKR patients with acceptable psychometric properties, recommendable
for usage in future clinical trials and clinical practice. KOOS Greek version
(downloadable at the official site http://www.koos.nu/koosgreek.pdf ) was used in
the validity study.
