Background: Robotic‐assisted unicompartmental knee arthroplasty (rUKA) aims to enhance the precision and reproducibility of implant positioning compared with manual UKA (mUKA). This systematic review and meta‐analysis compared radiographic, clinical, and patient‐reported outcomes between rUKA and mUKA. Methods: A systematic search was conducted in PubMed, MEDLINE, EMBASE, Scopus and Web of Science (July 2025) for comparative studies of rUKA and mUKA, in line with the PRISMA statement. Data were pooled using random‐effects models, with effect sizes expressed as mean difference (MD), standardized mean change (SMC), or odds ratio (OR) with 95% confidence intervals (CIs). Results: Thirty‐four studies encompassing 68,196 UKAs (22,585 robotic; 45,611 manual) were included. rUKA demonstrated significantly lower complication (OR 0.66, 95% CI 0.44–0.99; p = 0.045) and revision rates (OR 0.54, 95% CI 0.39–0.75; p < 0.001). Operative time was longer for rUKA (+16.1 min; 95% CI 10.8–21.4), while length of stay trended shorter (MD −0.2 days; p = 0.44). rUKA was associated with greater functional outcomes, including higher KSS Knee (MD 2.49; p = 0.007), KSS Function (MD 2.33; p = 0.008), and Oxford Knee Score (SMC 1.06; p = 0.049). Radiographically, rUKA yielded lower tibial slope deviation (MD −1.75°; p < 0.001) and reduced variability in tibial slope and hip‐knee‐ankle alignment. Conclusion: rUKA may offer benefit compared to mUKA across radiographic precision, complications, revisions, and functional outcomes, though high heterogeneity in study design and the absence of UKA‐specific minimal clinically important difference thresholds limits the relevance of any rUKA benefit at present. Further large, multicenter, and methodologically robust studies are needed to confirm long‐term results and better define the role of rUKA in clinical practice.

A 73-year-old woman was referred to a National Centre for Peripheral Nerve Injury with a post-operative left radial nerve degenerative lesion following open reduction and internal fixation of a proximal third humerus fracture using radiolucent Arthrex FiberTape® Cerclage as an adjunct to plating to improve stability. Intra-operative photographs illustrate compression of the radial nerve under the cerclage construct. Use of radiolucent cerclage for humerus fractures is increasing with modern systems capable of withstanding an ultimate load of 4300 N. We highlight the risk of debilitating neurological injury when not deployed safely and describe anatomical high-risk zones for injury. We emphasize the impact of delay in diagnosis and treatment.

Introduction: Pelvic fractures (PF) are relatively uncommon but account for approximately 3% of all skeletal injuries. We aimed to assess the burden of PFs across high health expenditure countries by describing the trends in PF incidence rates over the last three decades. Methods: Using the Global Burden of Disease (GBD) Study database, we extracted sex specific PF age-standardised incidence rates (ASIRs) from 1990-2019 for each of the 19 European Union (EU) 15+ countries. We performed Joinpoint regression analysis to characterise the trends. Results: Over the 30-year period of study, 89% of countries experienced a decline in ASIRs for males, with a median percentage change of -11.8%, in comparison to females where 53% of countries experienced an increase in ASIR (median percentage increase of +3.1%). For females, the largest increases in PF incidence were observed in the Netherlands and Belgium; these were also the only two counties with increased overall PF incidence in males over the study period observed. The countries with the greatest decrease in ASIRs were Italy and Denmark for females and Portugal and Spain for males. Joinpoint regression identified that over the time periods covered by the most recent trends, PF incidence rates had increased in 58% of countries for females and 52% of countries for males. Conclusion: We found overall decreased incidences of PFs amongst males over the last 3 decades, compared with increased incidence in females. However, joinpoint regression analysis demonstrated a trend towards rising incidence of PFs amongst both males and females in recent years.
