The coronavirus disease 2019 (COVID-19) pandemic is an enormous challenge for health care systems worldwide. Although it is widely accepted that orthopedic service has been reduced during the COVID-19 pandemic, little is known about the magnitude and qualitative characteristics of this reduction. The aim of the present study is to quantify the impact of the COVID-19 pandemic on everyday orthopedic practice and to detect the qualitative details of this impact in order to provide data for appropriate planning of health care policy. Data from the year 2020, when the COVID-19 pandemic occurred, regarding the number of patients examined in the emergency department, outpatient clinics, as well as the number of hospital admissions, were recorded for each month. The number of surgical procedures per month was also recorded and evaluated in relation to the category and the anatomical region that these procedures pertained to. Similar data from the year 2019 were used as a control group. The mean number of patients who visited the emergency department, the outpatient clinics, and those who were admitted to the hospital per month decreased by 47.2%, 30.4%, and 9%, respectively. Overall, the mean number of orthopedic operations decreased by 11.7%, with trauma operations being reduced by 8.9% and elective operations by 13% per month. Based on the findings of the present study, the impact of the COVID-19 pandemic on orthopedic patients is definitely negative. The establishment of new guidelines and re-distribution of resources is required to return to a normal function of orthopedic practice within hospitals.

The coronavirus disease 2019 (COVID-19) pandemic is an enormous challenge for health care systems worldwide. Medical practice has shifted toward the treatment of patients with the COVID-19 disease. Both human and economic resources are redistributed for the creation of additional facilities to meet the increased requirements of those patients.

Orthopedic practice has definitely been affected both for its elective and emergency service [1] . Patients with chronic musculoskeletal disorders are advised to postpone definitive treatment if possible and access to outpatient clinics is restricted following guidelines issued by medical authorities. On the other hand, emergency orthopedic service remains unaltered, and all trauma patients receive appropriate treatment as they did before the pandemic. Although it is widely accepted that orthopedic service has been reduced during the COVID-19 pandemic, little is known about the magnitude and qualitative characteristics of this reduction.

The first COVID-19 patient in Greece was diagnosed on February 26, 2020, and since then the pandemic has spread across the whole country. Health authorities issued restrictions for most social activities since then, and from March 23, 2020, a strict lockdown was applied in the whole country for six weeks. A gradual restart of social activities was allowed by the end of June 2020 although recommendations regarding social distancing and mask-wearing remained. Following a second wave of the pandemic, a new lockdown was ordered commencing November 9, 2020, until the end of the year. During the first lockdown, all hospital admissions were suspended except trauma and emergency patients. Outpatient clinics were canceled and elective operations were postponed. During the second lockdown, government directives were to diminish elective procedures and outpatient clinic attendances by 80% to overload the health care system and to preserve stuff and equipment for COVID-19 patients [2] .

The aim of the present study is to quantify the impact of the COVID-19 pandemic in everyday orthopedic practice and to detect the qualitative details of this impact in order to provide data for appropriate planning of health care policy.

The study was performed in an academic orthopedic department within a public hospital in Greece, which is a tertiary referral center for both elective and emergency practice. After ethical approval by the Institutional Review Board of KAT Hospital, medical records of all patients who were admitted in our department in 2019 and 2020 were retrospectively analyzed. Patient hospitalization, outpatient clinics, and emergency department visits, elective and trauma operations for each month of the above two-year period were recorded.

Our department is in a non-COVID-19 hospital, although there is an intensive care unit dedicated to treating COVID-19 patients. During the first six months of the pandemic, every new admission was screened for COVID-19 symptoms, and a thorough travel and contact history was recorded. For patients at risk, a reverse transcription-polymerase chain reaction (RT-PCR) test for severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) was carried out. Since July 1, 2020, a negative RT-PCR test was required from all patients prior to admission to the hospital.

For each month of 2019 and 2020, differences in the number of patients examined in the emergency department and the outpatient clinics, as well as the number of patients admitted to our department for further evaluation, were recorded. The number of surgical procedures was also recorded and evaluated in relation to the category (emergency or elective) and the anatomical location that these procedures were performed.

Data from the year 2019 were used as a control group since the operation of our department had not yet been affected by the COVID-19 pandemic. Differences between each month of 2019 and 2020 were documented. Data were analyzed separately for each month because the impact of the COVID-19 pandemic was not equally distributed, as different restrictions and guidelines were in use throughout the year 2020.

Statistical analysis was performed using the IBM Statistical Package for the Social Sciences (SPSS) v. 22.0 for Windows (IBM Corp, Armonk, NY). Descriptives of all the examined variables are provided for each month of the examined years. Continuous cohort variables were compared using the Mann-Whitney U test with Bonferroni correction to adjust for multiple comparisons. P-value <.05 was considered statistically significant.

A mean decrease of 47,2% in the mean value was recorded when comparing the number of patients examined in the emergency department during the pre-pandemic year 2019 and the pandemic year 2020. The number of visits dropped from 1042.3±160.3 per month in 2019, to 550.3 ± 239.2 per month in 2020 (p < 0.001) ( This drop was noted during the whole year of 2020, except January, when the COVID-19 pandemic was not present, and June, when restriction measures had been withdrawn (Table 2; Figure 1 ). Table 3) . This reduction was documented during the entire 2020 but was more prominent during March, April, and May, when the first lockdown had been issued ( Table 3 ; Figure 2 ). The mean value of hospital admissions decreased by 9% from 186.6 ± 21.9 per month in 2019 to 169.8 ± 41.3 per month in 2020. This difference was not statistically significant ( Table 1) . When studying hospital admissions by month, it was found that a noticeable reduction was present during March (20.5%), April (50.8%), and May (41.4%) of 2020 as well as December (31.7%) of 2020 when the first and second lockdown had been ordered respectively ( Table 4 ; Figure 3 ). The mean value of overall orthopedic operations (elective as well as trauma) performed in our department decreased by 11.7% from 88.4 ± 10.8 per month of 2019 to 78.1 ± 14.1 per month of 2020 (p=0.035). This reduction was evident throughout 2020, except for January and August, when an increase of 20.3% was recorded ( Table 5 ; Figure 4 ). The mean value of trauma operations fell by 8.9% from 58.2 ± 6.2 per month of 2019 to 53 ± 11.5 per month of 2020 while elective operations fell by 13% from 28.9 ± 8.3 per month of 2019 to 25.2 ± 12.2 per month of 2020. The reduction in both trauma and elective operations was not statistically significant ( Table 1) . The difference in the number of operations was not equally distributed throughout 2020 and a considerable variation was manifested between months (Table 6; Figure 5 ). Table 7 . 

Details for the different categories of trauma operations and their monthly distribution for the years 2019 and 2020, respectively, are shown in Table 8 and Figure 6 . Table 7) . Monthly distribution and absolute numbers of different categories of elective operations are shown in detail in Table 9 and Figure 7 . 

The government, in an effort to control the COVID-19 pandemic, imitated other countries' measures and adopted a strict lockdown during the two peaks of the COVID-19 pandemic, with a small quarantine-free period during summer months. People were instructed to stay home in order to stay safe, transportation between districts was prohibited, remote working was established, schools and universities suspended their operation, retail and leisure places were closed, and social distancing and mask-wearing became compulsory in an effort to eliminate the transmission of the virus among the population. As a consequence, people limited their activities and restrained visits to medical centers for chronic conditions mainly because they fear COVID-19 contamination. A notable decrease in patient numbers seeking medical consultation was monitored in hospitals, including orthopedic patients [1, 3] .

Initially, a significant decrease was reported in the number of patients who visited the emergency department in 2020 as compared to 2019. This is attributed to the restriction of most outdoor activities, leading to less traffic, occupational accidents, and sports injuries. Additionally, many patients with minor injuries did not ask for medical support, due to the fear of coming in contact with the COVID-19 virus or even due to altruistic motivation for health care workers [4] .

Similarly, a significant reduction was found in the number of patients examined in the outpatient clinics of our department throughout the whole year of 2020. This reduction was in accordance with the hospital's administrative policy, which reduced the available appointments and increased the waiting time between patients in order to avoid overcrowding and protect health care workers from virus contamination [5] [6] .

On the contrary, hospital admissions significantly decreased during the first lockdown in March, April, and May 2020, but this tendency was not so evident during the second lockdown in November and December 2020. Furthermore, a minor increase in hospital admissions was noticed during the summer months. Loosening of restrictions during summer for a quarantine-free tourist period and lighter restrictions during the second lockdown are possible explanations for these findings. Consequently, these strategies led to a rise in the number of trauma patients and those looking for the treatment of chronic orthopedic disease.

Compared with the significant reduction in the visits to the emergency department, the reduction of emergency operations was disproportionally lower, mainly because the hospital is a tertiary referral center and patients who visited our department were referred for operative management rather than simple orthopedic consultation. Hip fractures presented a rather stable monthly distribution throughout 2020 and when compared to 2019, their decrease was not statistically significant, as they represent a fragility type of fracture, occur after in-house falls, and mainly affect elderly people with many co-morbidities [7] . Lower limb trauma operations did not present any significant change. Interestingly, upper limb trauma operations increased, possibly because they are related to indoor activities, which were increased during the quarantine period. Emergency spinal operations were decreased mainly because road accidents and falls from height were diminished. The number of orthopedic infections that needed surgical treatment was similar between 2019 and 2020. Periprosthetic joint infections, osteomyelitis, and septic arthritis are considered surgical emergencies and their number remained unaffected, as they represent complications of previous surgical interventions in the pre-pandemic period.

Restriction of elective operations was among the first measures that were adopted after the outbreak of the COVID-19 pandemic. Health authorities postponed the majority of elective surgeries during the first lockdown and reduced their number by 80% during the second lockdown in an effort to preserve recourses and equipment for the treatment of COVID-19 patients [8] . Despite this policy, the reduction of elective operations during 2020 in our department was less marked. Apart from elective spinal operations, which presented a statistically significant decrease, the number of joint reconstruction procedures, knee arthroscopy, shoulder elective operations, and deformity corrections showed a lower decrease and followed a biphasic monthly distribution with a significant reduction during the lockdown months and a counterbalance during the rest of 2020 as compared to 2019. One possible explanation is that many elective orthopedic operations are considered as "urgent-elective" due to the severe disability they imply for the patient and are therefore prioritized as soon as restrictive measures are alleviated [9] [10] .

It is still unclear whether elective surgeries will return to their normal flow; however, it is certain that once this happens, the health care system will be confronted with a huge backlog of elective surgeries [11] .

Based on the findings of the present study, the impact of the COVID-19 pandemic on orthopedic practice is definitely negative. The access of patients with orthopedic problems is restricted and elective operations are postponed following restrictions issued by policy-makers. It is not clear what the consequences of the currently applied policy will be in the long term. It is crucial to re-establish the guidelines in order to reschedule the elective operations. There is no doubt that precautions for virus spread must be enforced and supplementary resources should be re-distributed in order to return to the normal function of orthopedic practice; otherwise, the negative impact of the COVID-19 pandemic will be sustained and many disabled patients with orthopedic diseases will lose any access to treatment.
