Return to Soccer After Anterior Cruciate Ligament Reconstruction: An Outcome or a Decision?

The return-to-sports rate is often used as an outcome measure after anterior cruciate ligament (ACL) reconstruction (ACLR). Although most soccer players want to return to sports after their ACL injury, up to 40% do not believe they will return to soccer after their ACL injury.

To investigate whether self-reported presurgical beliefs regarding return to soccer correspond to registered official match participation after ACLR.

Cohort study; Level of evidence, 2.

Included were soccer players with a primary unilateral ACL injury who were ≥15 years at the time of ACLR and who had completed a presurgical question about their future sports participation beliefs. ACLR surgical data were extracted from the Swedish National Knee Ligament Registry, and game participation data were extracted from the Swedish Football Association's administrative data system.

A total of 959 soccer players (617 [64%] male and 342 [36%] female) were included. The follow-up time after ACLR ranged from 18 months to 5.5 years. Of 720 soccer players (75%) who believed that they would return to play (RTP), 462 (64%) players actually did. Of the players who believed that they would not RTP, 181 (76%) did not. Presurgical beliefs predicted RTP (odds ratio [OR], 5.59; P < .001). Younger age at the time of ACLR favored RTP, where 61% of the players aged 15-20 years had RTP (OR, 3.85; P < .001). At the top competitive level, 84% of the players RTP compared to 14% at the recreational level. Players active at higher levels were more likely to believe that they would RTP, and they also actually did so (OR, 33.06; P < .001). Overall, 67% of players followed their presurgical intention to return to soccer.

The findings indicated that presurgical beliefs, age, and level of play helped to predict the actual RTP of soccer players after ACLR.
