Enhanced recovery principles applied to revision hip and knee arthroplasty leads to better patient outcomes.

Aims There is very little published literature on Enhanced Recovery Principles (ERP) used in primary joint replacements applied to revision hip and knee arthroplasty (rTHA, rTKA). Methods Retrospective series of 268 rTHA and rTKA surgeries from 2010 -2018, treated with ERP, focusing on multimodal pain management, blood management and early functional recovery. Results No patients from the latest cohort required readmission within 6 weeks. Only 20 patients (7.5%) required a blood transfusion. Surgical site local anaesthetic infiltration was associated with lower PCA use in aseptic rTHA and rTKA (p<0.001; p<0.001). Revisions for infection had a longer length of stay (LOS) and increased PCA usage in both rTHA (6.5 vs. 5.2 days) and rTKA (10.1 vs. 5.3 days), similar to our previous study.1 Use of an intra-articular catheter for analgesia in rTKA showed reduced PCA use. Tourniquets were not beneficial for blood loss in rTKA and had greater PCA use post-operatively (p<0.001). Conclusion The application of ERP to revision THA and TKA surgery is safe and effective.
