Regarding the fact that knee arthroplsty is the definitive and ultimate treatment for this disease, we survey the short term result of this modality.
Methods: In this survey 34 patients with knee arthrosis who have been admitted in Dr ali shariati university hospital, Tehran, Iran in a five years period (2001-2006) and have undergone knee arthroplasty. The relationship between, gender and the operation results were evaluated using the system of knee society knee score before and after the operation, causes of arthrosis, prosthesis to be used and the complications of the surgery.
Results: patients included 20 females and 14 males with the mean age of 67.37±5.25 year and the age specterum (51-78). In 15 patients the operation was done only in right knee, in 5 patients in the left knee and in 14 patients both knees were operated. The mean of functional score of the operated knee reached from 32.68±4.14 before operation (26-45) to 68.67±6.45 after that (59-82) and the mean of knee score reached from 30.6±3.8 before operation (22-39) to 86.4±6.34 after operation (73-92).
Conclusion: Regarding significant improvement in the functional score and the knee score and the low complication rate of knee arthroplasty it is recommended that in case of indication this operation be done as soon as possible because late attendance increases complications.

Background: The ability to recognize the severity of the disease in those who their survival depend entirely on admission to the intensive care unit, is very valuable clinically. This study aimed to evaluate the clinical effectiveness of modified sequential organ failure assessment (MSOFA) scale to predict mortality and length of stay in intensive care unit patients respectively.

Methods: This was a retrospective cross-sectional study conducted on hospital records of patients admitted to the intensive care unit. All patients’ records who admitted to the intensive care unit of Kowsar Hospital, Semnan city (the capital of the province), Iran, in 2015 considered as the sample. Collecting data were done during 4 weeks in April and May 2016. The data collection tool was a demographic questionnaire and modified sequential organ failure assessment scale. Exclusion criteria included discharge in the first 24 hours after admission, the patient died a few hours after admission and incomplete information to complete the modified sequential organ failure assessment form.

Results: The study of 105 patients' records of the intensive care unit showed that 45.7% of patients were died, 15.2% and 39% were discharged and moved to other wards respectively. The results of logistic regression analysis and receiver operating characteristic (ROC) curve showed that this criterion had moderate sensitivity and specificity for prediction of mortality and length of stay in ICU patients (Area=0.635, CI= 0.527-0.743) and each unit increase in modified sequential organ failure assessment score is accompanied by increasing 32 percent chance of death (OR=1.325; 95% CI:1.129,1.555; P= 0.001(. Also each unit increase in modified sequential organ failure assessment (MSOFA) score accompanied by increasing 19% length of stay in ICU (OR=1.191; 95% CI: 1.034, 1.371; P= 0.015(.

Conclusion: The results of this study showed that the modified sequential organ failure assessment scale is not useful tool to predict the length of stay and mortality of patients admitted to the intensive care unit.
