Introduction:
Foot and ankle injuries in elite athletes can result in decreased performance, absence from sport and prolonged morbidity. There is paucity of data on foot and ankle injuries in Olympics athletes.
Methods:
We conducted a systematic review of the PubMed and EMBASE databases. Studies in English language that reported the incidence and/or prevalence of foot and ankle injuries in during Olympics games (summer, winter and youth Olympics) were included. Studies in languages other than English, those that looked at injuries other than foot and ankle injuries, studies looking at injuries in non-Olympics events and those looking at Olympics trials were excluded. We determined the injury rates and burden of foot and ankle injuries. We also looked at the patterns and trends of foot and ankle injuries.
Results:
A total of 399 foot and ankle injuries from 25 publications were included in the review. Foot and ankle injury rates ranged from 0.09 to 0.42 injuries per athlete-years for summer Olympics and 0.02-0.35 injuries per athlete-years for winter Olympics. Quantitative analysis revealed that foot and ankle injuries contributed to 16.9% of all injuries (95% CI 8.1-31.9%) for summer Olympics and 5.1% of all injuries (95% CI 1.9-12.6%) for winter Olympics; however, a high statistical heterogeneity was noted. The three most common injuries were tendon injuries, ligament injuries and stress fractures. The rates and burden of foot and ankle injuries showed a declining trend.
Conclusions:
Foot and ankle injuries are an important cause of morbidity amongst Olympics athletes. The declining trend amongst these injuries notwithstanding, there is a need for a global electronic database for reporting of injuries in Olympics athletes.
