  • The purpose of this study was to examine the validity and reliability of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)-VA3.0 in patients with hip and knee osteoarthritis (OA). The sample consisted of 301 patients who had received treatments at the physical therapy units of 5 medical institutions in Andong City in june 2006. Questionnaires on the WOMAC were recruited by 12 physical therapists. The internal structure and reliability of the scales were evaluated by means of item-internal consistency (Cronbach's alpha coefficient: ${\alpha}$), item-discriminant validity, and Pearson's relation coefficient. To explore construct validity, we conducted a principal component factor analysis with varimax rotation analysis. The criterion for factor extraction was an eigenvalue >1.0. The average age of the patients was 62.1 years. All WOMAC subscales (pain, stiffness, and physical function) were internally consistent with Cronbach's coefficients of .81, .91, and .80, respectively. The internal consistency reliability of item-each scale were also internally consistent with Cronbach's coefficient of .89 (Pearson's correlation coefficient: .71~.84), .93 (.89~.91), and .96 (.67~.91), respectively. However, high correlation was found among 3 items (.66~.83, .66~.67, and .67~.83), so the item-discriminant validity was low (${\alpha}$ coefficient: .81, .91, .80, respectively). The construct validity by factor analysis was low because it was not consistent With WOMAC-VA3.0. In conclusion, the results reported here confirm the reliability of the WOMAC in patients with OA of the hip and knee. The collection of information on the hip and knee osteoarthritis using this instrument was acceptable to patients. A further prospective multi-center study will be necessary to prove the construct validity.

  • The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) is a valid and widely used instrument for the assessment of osteoarthritis patients. In this study, data was obtained from the out-patients with painful osteoarthritis of the knee. One hundred-three out-patients were interviewed by physical therapists. In an exploratory way, a Korean version of the KWOMAC was analyzed for unidimensionality, item separation, and item difficulty using the Winsteps programs. Ninety-five patients with osteoarthritis of the knee over 65 years were analyzed for Rash analysis. In the analysis several functional items poorly fit to the model. These items included "heavy domestic duties" and "standing". In the pain domain, one item ("at night while in bed") did not fit the model. In the stiffness domain one item ("after sitting, lying, or resting later in the day") did not fit the model. Although 4 items from the 3 domains (pain, stiffness, function domain) do not fit well, the KWOMAC domains were confirmed by Rasch analysis. Thus the KWOMAC needs to be further examined before it can be used to properly determine the health status of the elderly with OA.

  • Objectives : This study was done to show the clinical effect of miniscalpel acupuncture treatment on osteoarthritis of the knee which is refractory to acupuncture treatment. Methods : A patient was treated with acupuncture for three weeks, non-treated(wash out period) for two weeks, and treated with miniscalpel acupuncture for three weeks. The effect of treatments were measured with Visual Analogue Scale(VAS), Range of Motion(ROM), Short form McGill pain questionnaire(SF-MPQ), Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC). Results : During the three weeks of acupuncture treatment, VAS, SF-MPQ and WOMAC improved, but after two weeks of the wash out period each score worsened. During the three weeks of miniscalpel acupuncture VAS, SF-MPQ, and WOMAC improved while ROM improved remarkably. Conclusion : These results suggest that miniscalpel acupuncture might be a therapeutic option for knee degenerative osteoarthritis patients who does not responded to acupuncture treatment.

  • Purpose: To identify the effect of knee joint traction therapy on pain, physical function, and depression in patients with degenerative arthritis. Methods: In total, 30 patients with degenerative arthritis were randomly assigned to one of two groups: the experimental group, who underwent knee joint traction therapy, and the control group, who underwent general physical therapy (15 patients per group). Pain was measured using the visual analogue scale (VAS), physical function was measured using the Western ontario and McMaster universities osteoarthritis (WOMAC) index, and depression was measured using the Beck depression inventory (BDI). The VAS, WOMAC score, and BDI score were recorded before and after the 4-week treatment. Results: As a result of comparison within groups, the experimental and control group showed significant difference for VAS, WOMAC and BDI after the experiment (p<0.05). In comparison between the two groups, the experimental group in which knee joint traction was applied showed more significant change in VAS, WOMAC and BDI than the control group (p<0.05). Conclusion: This study showed that knee joint traction therapy was effective in improving pain, physical function, and depression in patients with degenerative arthritis.

  • Objectives: The purpose of this study is to investigate the effect of ultrasound therapy on left knee pain and instability diagnosed with Baker's cyst in a 25-year-old male patient. Methods: Patient was treated with Radio frequency ablation treatment on left knee from Naeseulan (EX-LE4) to Wijoong (BL40). The effect of radio frequency ablation was assessed by Visual Analog Scale (VAS), Western Ontario and McMaster Universities (WOMAC) and Euro Qol-5 Dimension Index (EQ-5D Index). The treatment was executed one time a day everyday form May 28th to June 1st of 2020. Patient was observed from May 26th to June 1st. Results: After five sessions of radio frequency ablation, VAS of left posterior knee pain was improved while no improvement was discovered at left medial knee. In Korean WOMAC scale, only subscale of weight bearing and walking around plain were improved. EQ-5D did not show any improvement. Conclusion: The results suggest that radio frequency ablation treatment can be a valuable option in treating knee pain and daily living function. Further study seems to be needed based on long-term intervention.

  • The aim of this study was to investigate the efficacy of thread-embedding therapy for the treatment of knee osteoarthritis. There were 20 patients treated with thread-embedding therapy at various acupoints on the muscles around the knee. Gender, age, location, morbidity period, numeric rating scale (NRS), Western Ontario and McMaster Universities (WOMAC) index, improvement result, side effects, and patient's satisfaction were investigated. After the treatment, the NRS score (z = -4.07, p < 0.001) and WOMAC (p < 0.001) indices decreased in most patients. The NRS score decreased by more than 2 points in 95% of the patients. The WOMAC index decreased by 6-12 points. There were no serious side effects, although bruising, pain, and edema were observed. Overall, 85% of the patients felt satisfied with the thread-embedding therapy. These findings suggested that thread-embedding therapy was effective and may be used widely for knee osteoarthritis.
