This systematic review on return to sport RTS after Total Hip Arthroplasty found that most patients are able to return to preoperative levels of low- (eg, walking) and moderate-impact (eg, hiking) sports between 7 and 12 months after THA. Patients planning a return to high-impact (eg, singles tennis, soccer) sports should be counseled on the possible risks of traumatic injuries and aseptic loosening and monitored closely. The best prognostic indicator for RTS was previous experience in that sport.

In this study, between August 2020 and March 2021, football players who tested positive for SARS-CoV-2 were identified through media search (professional level) and a nationwide registry in Germany (amateur and youth level). Out of 1247 identified football matches and training sessions, 104 cases were detected. Follow-up PCR testing at the professional level revealed no transmission. At the amateur and youth level, 2 detected transmissions were attributed to non-football activities. Video analysis of 21 matches demonstrating frontal contacts were <1 per player-hour, each lasting no longer than 3 s. In conclusion, on-field transmission risk of SARS-CoV-2 in football is very low.

This study analyzed data about football exposures and injury occurrence in 6 teams participating in Copa Libertadores in 2016, comparing with teams participating in the UEFA Elite Club Injury Study during the 2016 and 2017 seasons. A training injury incidence of 3.2 (2.7 to 3.7), significantly higher than the European teams, and match incidence of 20.9 (17.3 to 25.1) injuries/1000 hours, similar to the European teams, were recorded. While no differences in muscle injury incidence were observed, the ligament injury incidence in training among South American teams was significantly higher than European teams (0.6 vs 0.3)
