ARTICLE HIGHLIGHTS
Research background

Between 43% and 75% of patients who undergo primary anterior cruciate ligament (ACL) surgery return to sport activity. However, after a revision ACL reconstruction (ACLR) rate of return to sport are variable. Few publications report return to sports incidence between 56% to 100% after revision ACLR. Five-year minimum follow-up after revision ACLR is a good mid/long-term period evaluation to report return to sport of a case series patients.

Research motivation

Return to sports is a frequent question from patients during the first consultation. We believe this research could help other knee surgeons answer these types of questions. Motivation and expectation must be asked by surgeons during the consultation so as to give the patient a more detailed and realistic response to that question.

Research objectives

The objective was to report functional clinical outcomes and return to sport at a mid/long-term period after revision ACLR.

Research methods

A retrospective and observational study was performed to describe return to sport of an amateur case series of patients. The entire cohort was asked about motivation, expectation, intensity, frequency and level of return to sport after a 5-year follow-up after revision ACLR.

Research results

Thirty-nine percent of the cohort returned at the same level compared to the pre-injury period. Sixty-one percent returned at a lower level. Sixty-three percent categorized the sport as very important and 37.0% as important. One patient (2.4%) failed with a recurrent torn ACL.

Research conclusions

Almost 40.0% of patients returned to their pre-injury sport level and 60.0% to a lower level after 5 years of follow-up after revision ACLR.

Research perspectives

The direction of future research must be to compare return to sport of professional elite patients against amateur patients.
