Clinical And Radiological Results

(1) Background: Studies show several advantages of unicompartmental knee replacement (UKR) over total knee replacements (TKR), whereas registry based revision rates of UKR are significantly higher than for TKA. Registry data report lower revision rates for cementless UKR compared to cemented UKR. The aim of this study was to assess clinical and radiological results of cementless Oxford UKR (OUKR) in an independent cohort. (2) Methods: This retrospective cohort study examines a consecutive series of 228 cementless OUKR. Clinical outcome was measured using functional scores (Oxford Knee Score (OKS), American Knee Society Score (AKSS), Hannover Functional Ability Questionnaire for Osteoarthritis (FFbH-OA), range of motion (ROM)), pain and satisfaction. Radiographs were analyzed regarding the incidence of radiolucent lines (RL), implant positioning, and their possible impact on clinical outcome. (3) Results: At a mean follow-up of 37.1 months, the two and three year revision free survival-rates were 97.5% and 96.9%. Reasons for revision surgery were progression of osteoarthritis, inlay dislocation and pain. All clinical outcome scores showed a significant improvement from pre- to postoperative. The incidence of RL around the implant was highest within the first year postoperatively (36%), and decreased (5%) within the second year. Their presence was not correlated with inferior clinical outcome. Implant positioning showed no influence on clinical outcome. (4) Conclusion: Cementless OUKR showed excellent clinical outcome and survival rates, with reliable osteointegration. Neither the incidence of radiolucent lines nor implant positioning were associated with inferior clinical outcome.

Introduction: The design of some knee replacements includes the use of a mobile polyethylene bearing which can potentially dislocate away from the main bearing surfaces. This is particularly the case in unicompartmental or partial knee replacements (UKRs), and the most widely used UKR currently has this feature. Bearing dislocations are typically very painful and disabling, but not always, as in the case we present. Case Report: We report the case of a patient presenting at a 1 -year follow- up following a mobile bearing UKR. At this consultation, the patient reported a smooth initial recovery but with on-going pain and swelling in the posterior aspect of his knee for 3 months, diagnosed as a soft- tissue strain. Results: Radiographs at 1 year follow-up appointment showed that the polyethylene insert was dislocated posteriorly towards the popliteal fossa with metal components in direct contact. At revision surgery, this was confirmed as a chronic dislocation with severe metallosis requiring revision to a total knee replacement. Conclusion: We report a case of a posterior dislocation of a mobile polyethylene bearing of a partial / unicompartmental knee replacement UKR with delayed definitive treatment due to mis-diagnosis at the time of onset of symptoms and signs. The key lesson is that plain radiographs should be obtained promptly for any local issue in knee replacement patients. Keywords: Unicompartmental knee replacement, metallosis, mobile bearing dislocation, soft tissue injuries.

Abstract 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.
