To investigate the incidence and risk factors associated with loss of motion after anterior cruciate ligament reconstruction (ACLR) during the coronavirus disease 2019 pandemic (COVID-19). A retrospective review of patients undergoing primary ACLR between March 2017 and November 2022 by a senior high-volume orthopaedic surgeon was performed. Exclusion criteria included revision ACLR, multiligamentous knee surgery, and age <14 years. The COVID-19 group was categorized according to the United States Centers for Disease Control Public Health Emergency declaration dates (January 31, 2020-May 11, 2023). To minimize confounding variables associated with the early stages of COVID-19, patients who underwent ACLR between December 1, 2019 and February 29, 2020 were excluded. Loss of motion was defined using the International Knee Documentation Committee criteria for loss of motion of the knee (i.e. an extension deficit >5° or flexion deficit >15° compared to the contralateral knee) 3-12 months after ACLR or as requiring surgery to restore motion within 12 months of ACLR. A total of 336 individuals who underwent 352 primary ACLRs (164 pre-COVID-19, 188 during COVID-19) were included (mean age: 25.2 ± 10.6 years, 44% female). The overall rate of postoperative loss of motion was 15% (n = 53), and 9% (n = 31) required surgery to restore motion within 12 months of ACLR. More patients underwent surgery for loss of motion during COVID-19 compared to pre-COVID-19, which was statistically significant (12% (n = 23) vs 5% (n = 8), respectively, P = 0.02). However, a statistically significant difference in the rate of loss of motion was not detected (18% (n = 33) vs 12% (n = 20), respectively, P = 0.16). A statistically significant increased median time from injury to ACLR was observed during COVID-19 compared to pre-COVID-19 (55 vs 37 days, P <0.01). More patients were unable to achieve terminal extension (0°) at minimum 9 months postoperatively during COVID-19 compared to pre-COVID-19 (10% vs 3%, P = 0.04) and motion was worse at this interval (0°-136° vs -2°-138°, P <0.01). Surgery for loss of motion following ACLR was more common during COVID-19. Decreased access to elective medical care, changed activity level, psychological effects, or COVID-19 itself may explain the increased rate of surgery for loss of motion during COVID-19. Case series; level IV.
