Objectives The purpose of this study is to compare the effects between the KL-Grade and improvement of knee pain treated by Korean Medicine therapy.
Methods 114 patients who received inpatient treatment from July 2014 to May 2017 in the Daejeon Jaseng of Korean Medicine Hospital were divided into 5 groups by the KL-Grade. All patients received a combination of treatment including acupunture, pharmacopunture, herbal medication. They were compared and analyzed on the basis of improvement between measuring Numeric Rating Scale (NRS), Western Ontario and McMaster Universities Arthritis Index (WOMAC Index), EuroQol-5 Dimension Index (EQ-5D Index) as they were hospitalized and as they were discharged. The statistically significance was evaluated by SPSS 23.0 for windows.
Results After treatment, KL-Grade 0 group’s Numeric Rating Scale (NRS), Western Ontario and McMaster Universities Arthritis Index (WOMAC Index), EuroQol-5 Dimension Index (EQ-5D Index) improvement was 2.02±1.69, 7.50±9.67 and 0.11±0.15 respectively. KL-Grade 1 group’s improvement was 2.09±1.23, 11.75±13.99 and 0.12±0.13 respectively. KL-Grade 2 group’s improvement was 1.60±1.07 and 14.70±14.19 respectively. But In this group, EQ-5D Index has decreased by 0.01±0.10. KL-Grade 3 group’s improvement was 1.88±1.31, 7.81±13.35 and 0.13±0.20 respectively (p<0.034). In the case of KL-Grade 4, the population was not statistically significant (N=2) and therefore excluded from statistical significance. And there was no statistically significance between 4 group’s improvement after treatment (p>0.05).
Conclusions The above study showed that Korean medicine treatments showed significant therapeutic effects on knee pain and degenerative knee joints, but there was no significant difference in the effectiveness of degenerative arthritis (KL-Grade).
