Early Results of Single Anaesthetic Bilateral Fixed Bearing Cemented Medial Unicompartmental Knee Replacement

Introduction Unicompartmental knee replacement (UKR) results in less morbidity, early mobilisation, and better PROMs in appropriately selected patients. There has been a steady increase in the number of fixed bearing UKRs in the NJR. We present the early results of single anaesthetic bilateral fixed bearing cemented medial UKR. Method All patients undergoing bilateral UKR using the ZUK prosthesis (LIMA, UK) under a single anaesthetic between March 2013 and March 2019 were included in this study. Demographic data, surgical data, change in haemoglobin after surgery and occurrence of complications were prospectively recorded in the hospital database. Pre-op and follow-up Oxford knee scores were recorded. Statistical analysis was performed using SPSS 25.0 (IBM, USA) and paired t-test was used to analyse improvement in functional score. Results Nine patients were included in this study. The mean age was 53.2years (range 43-71 years). There were 2 females and 7 males. A significant improvement in Oxford knee score from a mean of 37.2 to 53.6(p < 0.01) was seen. The mean drop in Hb was 4.1mg/dl. The mean follow up was 28 months (range 12-76 months). Conclusions There was good improvement in functional scores without any significant drop in Hb. Therefore, it is a safe and beneficial procedure.
