No significant difference in skin contamination during anterior cruciate ligament reconstruction with and without preoperative skin cleaning

Purpose: This prospective study aimed to assess whether preoperative antiseptic skin cleansing reduces bacterial contamination and surgical site infections (SSI) following anterior cruciate ligament reconstruction (ACLR). We hypothesized that antiseptic cleaning would lower bacterial load, reducing contamination and early infections.

Methods: One hundred and nineteen patients scheduled for ACLR were included in this prospective, nonrandomized study. Individuals were divided into two groups. Patients in the intervention group applied octenisan® wash lotion daily for three days before surgery and used the wash solution instead of their usual shower gel. Additionally, they swiped their leg with octenisan® soaked gloves on the morning of the operation. The control group followed their usual wash routine with no specific instructions. Fluid samples were taken before surgery from the irrigation bag and at 15-min intervals from the reservoir of the sterile surgical drape during the procedure. Suture material used for the ACL graft and meniscus repair were also collected for testing. The samples were subjected to a 14-day incubation period. Follow-up included outpatient visits at 6 weeks, 12 weeks and 6 months with a final evaluation at 12 months.

Results: Contamination rates showed no significant difference between the control and intervention groups. The mean contamination rate in the control group was 6.4% (n = 22) and 6.6% (n = 24) in the intervention group (p = 0.28). At 12-month follow-up, 110 out of 119 participants were included (52 control, 58 intervention). T tests for age (p = 0.19), BMI (p = 0.66), and surgery duration (p = 0.38) showed no significant differences. No early SSI were observed in either group postoperatively.

Conclusion: Our results indicate that the use of antiseptic wash lotion and gloves does not influence the risk of bacterial contamination during surgery.

Level of evidence: Level III.
