CHANGES IN PHYSICAL ACTIVITY IN SWEDEN DURING COVID-19 : A COMPARATIVE CROSS-SECTIONAL ANALYSIS
- 2022
-
Conference paper (other academic/artistic)abstract
- IntroductionAccording to accumulated data, COVID-19 related restrictions can lead to considerable inactivity and sedentary lifestyles. The Swedish COVID-19 response consisted of guidelines rather than restrictions, which could possibly have a positive impact on activity levels remaining high. To investigate to which extent self-rated physical activity changed during the Swedish COVID-19 response, two cross-sectional surveys (N = 10,560) were conducted. The data constitutes the most comprehensive material on COVID-19 and physical activity extracted from Sweden. The aim is to contribute with new knowledge about general trends in physical activity during the Corona-pandemic in Sweden.MethodsThe method used is based on a quantitative cross-sectional retrospective approach. This approach makes it possible to clearly illustrate how the respondents’ (N = 10,560) answers differ depending on whether the questions referred to physical activity “before COVID-19” or “during COVID-19”. The data was collected on two different occasions (dataset 1 & dataset 2). Both surveys were digital questionnaires. The first dataset was distributed through social media, and The Swedish Research Council for Sport Science, whereas the second survey was distributed via e-mail. Dataset one was collected between 8 April 2020 to 14 august 2020, while dataset two was gathered from 8 December 2021 to 22 January 2021. The analysis included descriptive statistics, t-tests, correlations, and ANOVA. Cohen’s guidelines were used to establish what should be considered small, medium, and large differences.ResultsOverall, the results convey that there are significant differences for many people in everyday exercise performance during COVID-19. The most striking result is that many respondents report the same amount of everyday exercise, however, less physical training, and more sedentariness. Moreover, the result shows that elderly respondents were more affected than younger people, yet younger people reported more increased time sitting down. In terms of gender, although the Cohen guidelines categorize the difference as small, women had higher scores on sedentariness and reduced physical activity. DiscussionBoth datasets reveal that patterns of physical activity have changed during COVID-19. However, contrary to what some studies conducted in Sweden have argued, within our datasets, differences across gender and age yielded only small differences. This deviates from studies that report that COVID-19 had a substantial negative impact on certain demographic groups. We conclude that respondents report less physical training regardless of demographic specificities. That elderly report less movement aligns with the outcomes of similar large-scale studies conducted in other countries. Finally, we suggest that one reason for differing results could be the use of different definitions when employing questionnaires to gain information on perceived physical activity.

Journal article (peer-reviewed)abstract
- The cam deformity may cause impingement and probably leads to osteoarthritis of the hip. The aetiology of the cam deformity is incompletely understood. Vigorous training during skeletal growth can lead to the development of cam and symptoms of femoro-acetabular impingement and subsequent osteoarthritis of the hip. The purpose of this study was to compare the radiographic characteristics and range of motion between a group of athletes and a non-athletic control group. Thirty-two male athletes (17 soccer players and 15 ice-hockey players) and thirty non-athletes, used as a control group, were examined clinically and radiographically. Hip range of motion was measured and the FADIR and FABER tests were performed. Standard radiographs of both hips were taken. The centre-edge angle, alpha angle, caput-collum-diaphysis angle, head-neck offset and Tonnis grade were registered. The athletes had a higher Tonnis grade (right P = 0.009, left P = 0.004), more pain on the FADIR test (right P = 0.006, left P = 0.001) and lower ROM in internal (right P = 0.003, left P = 0.025) and external rotation (P < 0.001). A superiorly placed cam deformity (seen on an AP pelvis view) was correlated with reduced external rotation (right P = 0.001, left P = 0.004) and mild osteoarthritis (Tonnis grade 1), (P = 0.015, left P = 0.020), while a more anteriorly placed cam deformity (seen on a modified Lauenstein view) was correlated with reduced internal rotation (right P = 0.029, left P = 0.013). A lower range of motion, more osteoarthritic changes and more pain were found in the athletes than the controls. The control group had more cam deformities than previously reported.

Prior hip arthroscopy does not affect 1-year patient-reported outcomes following total hip arthroplasty: a register-based matched case-control study of 675 patients
- 2021

Journal article (peer-reviewed)abstract
- Background and purpose - Femoroacetabular impingement syndrome (FAIS) is a common cause of hip pain and may contribute to the development of osteoarthritis. We investigated whether a prior hip arthroscopy affects the patient-reported outcomes (PROMs) of a later total hip arthroplasty (THA). Patients and methods - Patients undergoing hip arthroscopy between 2011 and 2018 were identified from a hip arthroscopy register and linked to the Swedish Hip Arthroplasty Register (SHAR). A propensity-score matched control group without a prior hip arthroscopy, based on demographic data and preoperative score from the EuroQoL visual analogue scale (EQ VAS) and hip pain score, was identified from SHAR. The group with a hip arthroscopy (treated group) consisted of 135 patients and the matched control group comprised 540 patients. The included PROMs were EQ-5D and EQ VAS of the EuroQoL group, and a questionnaire regarding hip pain and another addressing satisfaction. Rate of reoperation was collected from the SHAR. The follow-up period was 1 year. Results - The mean interval from arthroscopy to THA was 27 months (SD 19). The EQ-5D was 0.81 and 0.82, and EQ VAS was 78 and 79 in the treated group and the matched control group respectively. There were no differences in hip pain, and reported satisfaction was similar with 87% in the treated group and 86% in the matched control group. Interpretation - These results offer reassurance that a prior hip arthroscopy for FAIS does not appear to affect the short-term patient-reported outcomes of a future THA and indicate that patients undergoing an intervention are not at risk of inferior results due to their prior hip arthroscopy.

Diagnosis and management of periprosthetic joint infections
- 2020
-
Doctoral thesis (other academic/artistic)abstract
- Periprosthetic joint infection (PJI) is a severe complication to hip and knee arthroplasty surgery. In the light of its devastating implications for the affected patient, its great economic impact on the health care system and the increasing antimicrobial resistance, it is important to develop efficient diagnostic methods, identify optimal treatment pathways and improve the care for patients. Using a microbiological approach, Paper I aimed to identify the impact of biofilm production and susceptibility on clinical outcome. The result showed a greater risk of persisting PJI in patients infected by strong biofilm producing staphylococci compared to non- or weak biofilm producers, suggesting the implementation of biofilm diagnostics in clinical routine. Paper II aimed to compare two surgical techniques of DAIR (debridement, antibiotics and implant retention) treatment using a register-based approach. The superiority of modular component exchange compared to non-exchange was established and the exchange of modular components should be employed in cases where DAIR is a viable option. In terms of implant extracting treatment, Paper III aimed to identify re-revision rates after one- and two stage revision procedures using a national register. No difference in re-revision rates were observed, supporting the use of the one-stage procedure which is a more economic choice and more lenient alternative for patients. Paper IV aimed to investigate the experiences and emotional impact of PJI on surgeons using qualitative analysis. The results confirm a negative emotional impact in surgeons and highlight the importance of multi-disciplinary work and inter-collegial support for optimal PJI management and for the well-being of surgeons.

Journal article (peer-reviewed)abstract
- Aims To investigate the experience and emotional impact of prosthetic joint infection (PJI) on orthopaedic surgeons and identify holistic strategies to improve the management of PJI and protect surgeons' wellbeing. Methods In total, 18 prosthetic joint surgeons in Sweden were recruited using a purposive sampling strategy. Content analysis was performed on transcripts of individual in-person interviews conducted between December 2017 and February 2018. Results PJI had a negative emotional impact on Swedish surgeons. Many felt guilt, stress, and a sense of failure, and several aspects of PJI management were associated with psychosocial challenges. Peer support was reported as the most important coping strategy as was collaborating with infectious disease specialists. Conclusion Our study affirms that there is a negative emotional impact of PJI on surgeons which can be minimized by improved peer support and working in multidisciplinary teams. Based on the surgeons' experiences we have identified desired improvements that may facilitate the management of PJI. These may also be applicable within other surgical specialties dealing with postoperative infections, but need to be evaluated for their efficacy.

Journal article (peer-reviewed)abstract
- Late chronic infection is a devastating complication after total hip arthroplasty (THA) and is often treated with surgery. The one-stage surgical procedure is believed to be the more advantageous from a patient and cost perspective, but there is no consensus on whether the one- or two-stage procedure is the better option. We analysed the risk for re-revision in infected primary THAs repaired with either the one- or two-stage method. Data was obtained from the Swedish Hip Arthroplasty Register and the study groups were patients who had undergone a one-stage (n = 404) or two-stage (n = 1250) revision due to infection. Risk of re-revision was analysed using Kaplan-Meier analysis with log-rank test and Cox regression analysis. The cumulative survival rate was similar in the two groups at 15 years after surgery (p = 0.1). Adjusting for covariates, the risk for re-revision due to all causes did not differ between patients who were operated on with the one- or two-stage procedure (Hazard Ratio (HR) = 0.9, 95% Confidence Interval (C.I.) = 0.7-1.2, p = 0.5). The risk for re-revision due to infection (HR = 0.7, 95% C.I. = 0.4-1.1, p = 0.2) and aseptic loosening (HR = 1.2, 95% C.I. = 0.8-1.8, p = 0.5) was similar. This study could not determine whether the one-stage method was inferior in cases when the performing surgeons chose to use the one-stage method.
