IKDC score after ACL reconstruction may predict safe return to sport

Patients who follow a structured rehabilitation program and a comprehensive return-to-sport assessment after ACL reconstruction can have a low graft rupture rate, according to presented results.
“A low graft rupture rate post ACL is possible. Patients with a higher IKDC score at 9 months were more likely to return to previous sport,” Antonio Klasan, MD, said at the Virtual EFORT Congress.
Klasan and colleagues conducted a retrospective analysis of 144 patients who underwent ACL reconstruction followed by an intensive rehabilitation program. The patients had a comprehensive return-to-sport assessment at 9 months, which included a Y balance test, distance, height and side-hop tests and an ACL-RSI questionnaire. Patients had KT-1000 arthrometry measurements taken preoperatively and at follow-up, and completed Tegner, Lysholm and IKDC questionnaires at that time as well. Mean patient age at the time of surgery was 29.6 years. Minimum follow-up was 2 years, and 20 patients were lost to follow-up.
Researchers found the predictive variable for return to sport was higher IKDC score at follow-up. The predictive variable for returning to the same level of play was pre-injury Tegner level. Patients who were more likely to sustain a graft rupture were those with a higher expected Tegner score and a side-to-side difference of more than 3 mm on the KT-1000 knee arthrometer test. The most common reason patients did not to return to sport was the previously injured knee.
