ABSTRACT
OBJECTIVES: This study aimed to evaluate the changes in knee pain, a dominant cause of physical disability, following the coronavirus disease (COVID-19) pandemic, and to identify factors affecting the changes in knee pain. METHODS: We analyzed the pre- and post-COVID-19 longitudinal dataset of the Nagahama Study. Knee pain was assessed using the Knee Society Score (KSS). The estimated KSS from the age and sex using regression model in the pre- and post-COVID-19 dataset was compared. Factors including the activity score, educational level, and various impacts of COVID-19 were analyzed for correlation analyses with changes in KSS. RESULTS: Data collected from 6409 participants showed statistically significant differences in KSS, pre- (mean = 22.0; SD = 4.4) and post-COVID-19 (mean = 19.5; SD = 6.4). Low activity score (p = 0.008), low educational level (p < 0.001) and undesirable financial impact (p = 0.030) were independently associated with knee pain exacerbation. CONCLUSION: The harmful effects of the COVID-19 pandemic on knee pain were suggested. People should be encouraged to engage in physical activities, such as walking, even despite the state of emergency. Furthermore, social support for economically disadvantaged groups may improve healthcare access, preventing the acute exacerbations of knee pain.
ABSTRACT
PURPOSE: This study aimed to evaluate the acceptability of 14 days of self-quarantine and the positivity rate of pre-operative severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) polymerase chain reaction (PCR) screening for patients undergoing elective orthopaedic surgery. METHODS: The self-quarantine programme and pre-operative SARS-CoV-2 PCR screening were initiated for patients who were scheduled for admission later than 7 May 2020 for elective orthopaedic surgery on admission. On the day of admission, the patients declared compliance with self-quarantine regulations. The admission was refused in cases of non-compliance. After admission, the patients underwent SARS-CoV-2 PCR screening. If PCR results were negative, isolation was terminated. If PCR results were positive, the surgery was postponed. If the patients had symptoms suspicious of coronavirus disease (COVID-19) after surgery, the PCR test was repeated. RESULTS: Overall, 308 patients (age: 63.2 ± 18.8 years, 197 female and 111 male) were scheduled for elective orthopaedic surgery. Two patients did not agree with the requirements of self-quarantine, and two other procedures were cancelled. No non-compliance was reported; thus, the completion rate of the self-quarantine programme was 304/308 (98.7%). Finally, 304 patients underwent PCR testing, and there were no positive PCR results. After cancellations of four operations due to reasons other than COVID-19, 300 surgical procedures were performed. No patients developed COVID-19 during hospitalisation. CONCLUSIONS: Although this system is based on trusting the good behaviour of patients, accompanied by PCR screening, we believe that the results showed the efficacy of the system in safely performing orthopaedic surgery during the COVID-19 pandemic.
