Abstract
Objectives To analyze the results of anterior cruciate ligament (ACL) reconstruction with remnant-preserving
versus remnant-resecting technique, concerning the return to pre-lesion activity level.
Methods The present retrospective cohort study has assessed adults > 18 years old who underwent
ACL anatomical reconstruction between 2010 and 2014. The main outcomes assessed were:
level of physical activity (4-point scale), sports participation rate, ACL rerupture
defined as documented lesion requiring revision surgery and the numeric pain scale
rate (NPSR).
Results A total of 83 individuals were included in the study, with a mean age of 31.8 years
old and follow-up mean time of 4.2 years after the surgery. A total of 34 patients
underwent ACL reconstruction with remnant-preserving technique, and 49 without remnant
preservation. No statistically significant difference was found between groups in
all outcomes assessed: level of physical activity before the lesion and after the
surgery, ACL rerupture rates and postoperative pain level. Subgroup analysis has shown
a statistically significant decrease in the activity level in both groups. The most
practiced sport was football; 72% of patients in the remnant group have resumed football
activity versus 52.6% of the control group.
Conclusion Based in these findings, the comparison between ACL reconstruction with remnant preserving
technique and remnant resecting technique has shown no differences concerning the
return to prelesion activity level.
