Impact of Covid-19 pandemic on injection-based practice: report from an Italian multicenter and multidisciplinary survey.

Background: There are no papers exploring the impact of COVID-19 pandemic on the injection-based practice in patients affected by different rheumatic diseases, including osteoarthritis. The aim was to investigate the impact of COVID-19 pandemic on injection-based practice trough the Italian country. Study design: A survey-based retrospective cross-sectional study. Methods: An Italian-language questionnaire was developed by a group of senior researchers and distributed by e-mail to some Rheumatology, Orthopedic and Rehabilitation Units from different geographic areas of Italy. The survey included information about the number of injections performed during COVID-19 pandemic (stratified by injected agents and injected joint), in comparison to the pre-pandemic period, and the possible reasons behind an eventual reduction. Responses were collected and descriptive analysis calculated. Results: Eleven centers of the National Health Service completed the survey. The activities of the injections services significantly decreased across the country with a percentage of reduction of 60% compared to the pre-pandemic period. A significant reduction of both intra-articular and peri-articular injections was registered. Among intra-articular. treatments, the most affected ones were the hyaluronic acid injections, when compared to corticosteroids. A significant decrease of the total amount of peri-articular injections was observed. The strict government restrictions and the fear of patients to become infected represented the most limiting factors. Conclusions: The reported decrease of the injection-based practice in our country during the COVID-19 pandemic highlights the detrimental effects of the COVID-19 pandemic on the management of chronic musculoskeletal diseases with possible negative consequences in terms of disability and quality of life.

Mini-subvastus versus medial parapatellar approach in total knee arthroplasty.

UNLABELLED: We compared short-term clinical results of the mini-subvastus approach with the standard parapatellar approach for total knee arthroplasty. Can one gain adequate access through the mini-subvastus approach without exceeding operating time, incurring additional complications, and maintaining correct implant geometry? In a prospective, observer-blinded study, 120 consecutive patients having total knee arthroplasty were operated on by one surgeon using either the mini-subvastus approach without patella eversion or the standard parapatellar approach with patella eversion. Patients were matched according to age, gender, body mass index, knee flexion, deformity, and pre-existing high tibial osteotomy. The mini-subvastus approach was technically more demanding. Reduced access and visibility prolonged the tourniquet time by an average of 15 minutes and led to two intraoperative complications. Patients in the mini-subvastus group lost on average 100 mL less blood and had better pain scores on day one [visual analogue scale (VAS): mean 2.4 versus 3.89]. They reached 90 degrees knee flexion earlier (2.8 versus 4.5 days), and an active straight-leg raise earlier (3.2 versus 4.1 days). Their average flexion at 30, 60 and 90 days was slightly better (100 degrees , 110 degrees , and 112 degrees versus 94 degrees , 106 degrees , and 109 degrees ). All patients including those with complications had good results with good component geometry and leg alignment. The mini-subvastus approach offers early but short-lived benefits for patients at the expense of a longer operation and a higher risk of complications.
