Background: The purpose of this study was to provide a comprehensive assessment of the impact of the COVID-19 pandemic on the epidemiology of primary and revision arthroplasties of the hip and knee joint. Methods: This study compared the data on knee and hip arthroplasty procedures from 2 hospitals (primary and revision) conducted in two periods: the period of the COVID-19 pandemic in Poland (from 4 March 2020 to 15 October 2020) and the corresponding period prior to the pandemic (from 4 March 2019 to 15 October 2019). We compared the epidemiological data, demographic data, and hospital stay duration data from these two periods. Results: Our analysis demonstrated that the total number of hip arthroplasties conducted in 2020 decreased by 26% in comparison with 2019. In the case of knee arthroplasties, the total number of procedures in the evaluated period in 2020 decreased by 44%. Our study also showed that the mean time of hospital stay for orthopedic patients following hip or knee arthroplasty was 22.87% shorter. The female-to-male patient ratio decreased between the analyzed periods, and this was 22.96% lower during the pandemic. Conclusion: The COVID-19 pandemic in these two hospitals in Poland led to reduced numbers of hip and knee replacement procedures, shorter hospital stays, and a decreased female-to-male patient ratio. The mean age of patients undergoing hip or knee arthroplasty remained unchanged during the national lockdown with respect to the pre-pandemic figure.
The purpose of our study was to comprehensively assess the effect of the COVID-19 pandemic on knee and shoulder arthroscopy performed in an orthopedic department of a university hospital in Poland. This study compared the data on all shoulder and knee arthroscopy procedures performed in two different periods: The period of the COVID-19 pandemic in Poland (from March 4, 2020, to October 15, 2020) and the corresponding period prior to the pandemic (March 4, 2019, to October 15, 2019). The study evaluated epidemiological data, demographic data, and hospital stay duration. The total number of arthroscopy procedures conducted in the evaluated period in 2020 was approximately 8.6% higher than that in the corresponding 2019 period. The mean duration of hospital stay for orthopedic patients after their knee or shoulder arthroscopy was 3.1 days in 2020 and 2.8 days in 2019. Our study revealed the mean age of arthroscopy patients during the pandemic to be lower at 48.4 years than the 51.2 years recorded in 2019. The male-to-female ratio was shown to be lower at .85 during the pandemic, having decreased from 1.5 in 2019. The COVID-19 pandemic did not reduce the number of arthroscopy performed at our center, and the mean age of the patients did not change. However, the pandemic had a marked effect on the mean duration of hospital stay and male-to-female ratio.
Background. The optimal duration of cast immobilization following distal radius fractures (DRFs) in elderly patients has not been established. Objectives.To assess the functional and radiological parameters following DRF treatment in elderly patients using 2 different periods of cast immobilization. Materials and methods.We assessed 50 patients (33 women and 17 men). The mean age at the beginning of treatment was 71 years. The mean duration of follow-up was 1 year and 3 months. One subgroup (n = 26) included patients treated with a cast for 4 weeks, whereas the other subgroup (n = 24) included patients treated with a cast for 6 weeks. The following measures were assessed: union rate, radial inclination, volar tilt, radial height, Visual Analogue Scale (VAS) pain score, Mayo Wrist Score, and VAS activity score.Results. The mean volar tilt was 9. 13° in the group treated with a cast for 4 weeks and 3.29° in the group treated with a cast for 6 weeks (p = 0.043). There were no differences between the groups in terms of any other functional or radiological parameters. Conclusions.The VAS pain score, Mayo Wrist Score and VAS activity score were similar between the 2 study groups. The greatest volar tilt angle was observed after 6 weeks of cast immobilization. The study groups showed no significant differences in terms of radial inclination, union rate, radial height, or bone union. A period of 4 weeks of cast treatment was sufficient for elderly patients with DRFs.

Background: Bilateral osteoarthritis of the knee is an indication for a bilateral total knee replacement (TKR) procedure. The goal of our study was to assess the sizes of the implants used during the first and second stages of TKR procedures in order to compare their size and identify the prognostic factors for the second procedure. Methods: We evaluated 44 patients who underwent staged bilateral TKR procedures. We assess the following prognostic factors from the first and second surgery: duration of anesthesia, femoral component size, tibial component size, duration of hospital stay, tibial polyethylene insert size, and the number of complications. Results: All assessed prognostic factors did not differ statistically between the first and second TKR. A strong correlation was found between the size of femoral components and the size of tibial components used during the first and second total knee arthroplasty. The mean duration of the hospital stay associated with the first TKR surgery was 6.43 days, whereas the mean duration of the second hospital stay was 5.5 days (p = 0.211). The mean sizes of the femoral components used during the first and second procedures were 5.43 and 5.2, respectively (p = 0.54). The mean sizes of the tibial components used during the first and second TKR procedures were 5.36 and 5.25, respectively (p = 0.382). The mean sizes of the tibial polyethylene inserts used during the first and second procedures were 9.45 and 9.34 (p = 0.422), respectively. The mean duration of anesthesia during the first and second knee arthroplasty was 117.04 min and 118.06 min, respectively (p = 0.457). The mean rates of recorded complications associated with the first and second TKR procedures were 0.13 and 0.06 per patient (p = 0.371). Conclusions: We observed no differences between the two stages of treatment in terms of all analyzed parameters. We observed a strong correlation between the size of femoral components used during the first and second total knee arthroplasty. We noted a strong correlation between the size of tibial components used during the first and second procedure. Slightly weaker prognostic factors include the number of complications, duration of anesthesia and tibial polyethylene insert size.
