Discussion LIA and FNB groups both showed a significant reduction at VAS score, better range of motion and less morphine consumption than CG (control group). LIA group has obtained a constant pain control in the postoperative days; FNB group had a good pain control in the hours after surgery, with a decrease in efficacy in the following days. Conclusion Further studies are still needed in order to define LIA as the reference pain management in TKA. © 2018 Delhi Orthopedic Association.

We hypothesise that a single high dose of Teicoplanin and Gentamicin is as effective as other regimes. Methods A retrospective study of prospectively collected data on a total of 4500 elective knee replacements over a 9-year period was conducted in a district general hospital. Data were collected on antibiotic regime, patient characteristics, infection (treatment, infective agents, sensitivities) and complications. Results Five different antibiotic regimes that have been used in elective knee arthroplasty were identified in our institution. 40 patients in total were identified who had a deep infection. Rates of deep surgical site infection were not significantly different between the five groups (p = 0.83). Conclusion A single pre-operative dose of Teicoplanin and Gentamicin has similar efficacy of prophylaxis to other regimes for patients undergoi
