As patients return to pre-COVID levels of activity, we hypothesize that there will be a resultant rebound increase in tendon ruptures.<\/jats:p>\n <\/jats:sec>\n \n Level of Evidence:<\/jats:title>\n III, descriptive epidemiology study.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n The electronic medical record was queried for current procedural terminology codes for tendon ruptures (Achilles, patella, quadriceps, hamstring, distal biceps, triceps, and pectoralis major) from January 2017 to December 2021 at a single academic urban center. Data were reviewed to ensure only acute tendon rupture repairs were included. The years 2017\u20132019 were used as a proxy for pre-COVID rates, 2020 as a proxy for the COVID quarantine, and 2021 as a proxy for \u201cpost-COVID\u201d activity. Univariate analysis was performed for comparative data.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n A total of 1,879 patients (82.8% male, mean age 47.8 years) who sustained tendon injuries and underwent surgical repair were identified. There were 589 (31.3%) Achilles tendon repairs, 181 (9.6%) patella tendon repairs, 414 (22.0%) quadriceps tendon repairs, 100 (5.3%) hamstring tendon repairs, 397 (21.1%) distal biceps repairs, 105 (5.6%) triceps repairs, and 93 (4.9%) pectoralis tendon repairs. The total number of tendon injuries per year was 2017\u2014357 (19.0%), 2018\u2014380 (20.2%), 2019\u2014380 (20.2%), 2020\u2014308 (16.4%), and 2021\u2014454 (24.2%). The rates in 2017, 2018, and 2019 were within 1% of each other, but there were a 3.8% decrease in rate of tendon injuries from 2019 to 2020 and a 7.8% increase in rate of tendon injuries from 2020 to 2021. When analyzed by quarter, a linear regression model demonstrated a statistically significant increase in case counts over the period from Q2 2020 to Q2 2021 (\u03b2 = 21.20; 95% confidence interval = 13.62\u201328.78,\n P<\/jats:italic>\n -value < .01).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n A \u201cCOVID rebound\u201d of tendon rupture repairs in 2021 from a prolonged period of inactivity during 2020 occurred at a single academic center. As patients return to pre-COVID levels of activity that may be unsuitable to their deconditioned state, healthcare providers should counsel patients appropriately on return to activity or sport following long periods of induced inactivity.<\/jats:p>\n
