Abstract

Background: Total knee arthroplasty (TKA) in patients with preexisting anterior cruciate ligament (ACL) reconstruction hardware poses unique surgical challenges. The need for hardware removal and complex exposure techniques distinguishes these cases from routine TKA.

Methods: This retrospective matched cohort study included 25 patients undergoing primary total knee arthroplasty (TKA) with prior anterior cruciate ligament (ACL) reconstruction hardware at IGIMS, Patna. Participants were divided into an ACL group and a matched control group without prior ACL reconstruction. Data on demographics, surgical parameters, estimated blood loss, and postoperative complications were collected and analyzed.

Results: The study included 10 patients in the ACL group and 15 in the control group. Operative time was longer in the ACL group (8–16 minutes), though differences in estimated blood loss (EBL) were not statistically significant. Postoperative complication rates were low and comparable between groups. Hardware removal was necessary in 82% of ACL group cases due to modern fixation techniques impeding safe instrumentation.

Conclusion: TKA in patients with prior ACL reconstruction requires meticulous preoperative planning to address extended operative times and surgical exposure challenges while achieving comparable outcomes to routine TKA.
