ABSTRACT

Objective:

To evaluate the long-term effect of structured patient education and exercise therapy for knee osteoarthritis (KOA).

Methods:

Prospective cohort study, 162 patients with KOA were consecutively recruited from May 2016 to December 2019 to receive structured patient education and exercise therapy and were followed up 3 years after the recruitment. All the patients received two 1-hour educational courses and exercise therapy twice per week for six weeks under the supervision of physicians or physical therapists. Knee injury and osteoarthritis score (KOOS), visual analog score of pain (VAS), intermittent and constant OA pain (ICOAP), self-efficacy for arthritis were queried at 3-month and 36-month follow-up visit. We fitted linear mixed-effects models to examine the difference in scores between baseline and 3-month and 36-month visits.

Results:

109(67.3%) patients finished both 3-month and 36-month follow-up visits. The KOOS pain score increased from 70.8±1.7 at baseline to 79.7±1.8 at 36 months ( P<0.05). The KOOS symptom score increased from 66.8±2.0 at baseline to 74.9±2.1 at 36 months ( P<0.05). The KOOS daily function score increased from 81.7±1.4 at baseline to 87.0±1.5 at 36 months ( P<0.05). KOOS motor function score increased from 47.4±2.8 at baseline to 55.0±2.9 at 36 months ( P<0.05). The quality of life score of KOOS increased from 46.6±2.1 at baseline to 63.5±2.2 at 36 months ( P<0.05). Compared with the baseline data, there were statistically significant improvements in all subscales of KOOS in 36 months after exercise therapy intervention ( F=14.548, 8.102, 11.394, 5.687 and25.942, P<0.05). VAS pain score of left knee, VAS pain score of right knee, ICOAP score, self-efficacy pain score and other symptoms were also significantly improved ( F=17.643, 26.791, 8.290, 4.052 and 3.654, P<0.05).

Conclusion:

Structured patient education and exercise therapy are effective in improving knee pain and function as well as self-efficacy until as long as 36 months.
