Abstract
BackgroundDistal femoral fracture is a rare, but significant, postoperative complication of anterior cruciate ligament reconstruction. However, there has not been a reported case of periprosthetic total knee arthroplasty fracture associated with a previous anterior cruciate ligament repair.Case presentationWe report the case of a 51-year-old white man with a history of total knee arthroplasty and remote anterior cruciate ligament reconstruction, who presented with a distal femoral periprosthetic fracture at the site of a previous anterior cruciate ligament augmentation staple.ConclusionsBased on these findings, it may be important to consider removal of previous anterior cruciate ligament hardware prior to total knee arthroplasty to reduce risk of periprosthetic fracture, which should be determined on a patient-specific basis.
Highlights
Distal femoral fracture is a rare, but significant, postoperative complication of anterior cruciate ligament reconstruction
Patients requiring anterior cruciate ligament (ACL) reconstructions typically present at a younger age and are more likely to partake in riskier athletic activities [2]
As far as the authors of the study are aware, there are no reported cases in the literature describing periprosthetic Total knee arthroplasty (TKA) fractures associated with the effects of a previous ACL reconstruction
Summary
Distal femoral fracture is a rare, but significant, postoperative complication of ACL reconstructive surgery. There has not yet been a reported case of periprosthetic fracture in well-established TKA associated with a remote ACL repair. Based on these findings, it may be important to consider removal of previous ACL reconstructive hardware prior to TKA to reduce risk of periprosthetic fracture, which should be determined on a patient-specific basis
