AbstractReturn to pre-injury level of sports activity and participation (RPSP) is one of the main reasons for undergoing anterior cruciate ligament reconstruction (ACLR), however previous reports have demonstrated great variations in the rate of return to pre-injury level of sports, ranging from 31% to 92%. Factors that influence RPSP after ACLR are not well known. The aims of this project were to: 1) conduct a cross-sectional survey study to determine RPSP (using a definition for RPSP that includes the type and frequency of sports participation and frequency of sports activities) of subjects that underwent ACLR 1 to 5 years prior to participation, 2) conduct a prospective observational study to determine RPSP 12 months after ACLR and 3) identify factors that influence RPSP after ACLR. 251 participants (mean age, 26.1±9.9 years) completed the survey that determined return to sports rate at an average of 3.4±1.3 years after ACLR. Using our definition, 122 (48.6%) participants RPSP. Thirty-five subjects who were between 14 and 35 years of age who participated in competitive or recreational sports prior to suffering a complete unilateral ACL tear were enrolled in our prospective study. Factors related to impairment and performance of knee function and psychological readiness to return to sports were evaluated. Using our definition for RPSP, only 14 participants (40%) returned to sports 12 months after ACLR. Participants’ mean age at the time of surgery was 19.79±4.64 years and 17 (48.6%) were females. The most common reasons for not RPSP in both studies were fear of re-injury and lack of confidence in the knee. Higher levels of psychological readiness for return to sports 3 and 6 months after ACLR predicted RPSP 12 months after ACLR. Individuals that were able to hop 6 months after surgery were also more likely to RPSP. Psychological factors need to be addressed during rehabilitation as early as 3 months after surgery to increase an individual’s confidence and thus return to sports. Individuals should also be encouraged to start activities such as hopping as soon as they become physically ready do so in order to increase their likelihood to RPSP 12-month after ACLR. Share
