Unicompartmental knee replacement has become a surgical alternative for treating isolated medial or lateral osteoarthritis of the knee or avascular necrosis of the femoral condyls. ⋯ Despite the higher revision rate to TKR in this study, our findings confirm the short-term results reported in other studies of the Oxford medial unicompartmental knee and our early failure rate could be explained by a performance learning curve. This study confirms that this bone-preserving procedure should be considered in end-stage isolated unicompartmental osteoarthritis or avascular necrosis by surgeons who have the adequate training and experience.

Acute kidney injury remains a common significant clinical problem. Yet there are scant data in Israel on the incidence of hospital-acquired AKI and on diagnosis validity. ⋯ Using AKI laboratory diagnosis as the gold standard revealed ICD-9 diagnosis to be 9.1% sensitive and 99.4% specific. Hospital-acquired AKI is a major contributor to prolonged length of stay and high mortality rates; therefore, interventions to reduce in-hospital disease incidence are required.
