Background: Knee
arthrosis is one of the most common and debilitating diseases in the advanced
ages. 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.

Abstract
Background: Shoulder hemiarthroplasty is one of the established methods for management of proximal humerus fractures particularly in the types with more displacement so that fixation is not possible. Successful treatment is a challenge for shoulder surgeons especially in elderly patients. The aim of this study is to investigate the functional results and prognostic factors on shoulder hemiarthroplasty.
Methods: Thirty nine patients operated by one shoulder surgeon in Imam Khomeini and Shariati Hospital in Tehran, Iran, from October 2005 to February 2009 were included in this study and followed postoperatively for at least one year. Mean (±SD) age was 49.7±14.3 years. Functional results were measured by constant score and pain was scored using visual analogue score. The relationship between factors such as age, injury to surgery interval, radiographic parameters and functional results were assessed. Results: Mean (±SD) constant score was 61.9±20.2. The age and injury to surgery interval showed a reverse correlation with constant score (p<0.05). There was a significant correlation between constant score and acromiohumeral interval (r=0.53) and head to tuberusity distance (-0.59). Median VAS score was 4.5 (interquartile range: 2- 5.2) that had a direct correlation with age (r=0.38) and injury to surgery interval (r=0.55) (p<0.05).
Conclusions: Shoulder hemiarthroplasty should be performed in minimal delay from injury and this operation should be performed by an experienced shoulder surgeon to create the best anatomic position of prostheses. Careful rehabilitation particularly in older patients is very important to improve results.

Abstract
Background: Dabigatran etexilate is one of the few direct thrombin inhibitors with anti-coagulant activities and the following distinctive features: taken orally, no need to closely monitor for complications, and no need for regular dose adjustments. Relying on the above mentioned valuable advantages, dabigatran etexilate can be considered as a premier choice for the prevention of venous thromboembolism after knee replacement arthroplasty.
Methods: Forty five patients undergoing 50 knee replacement surgeries were included in this case-series study undertaken in Hazrat Rasool Akram and Khatam-alanbia Hospitals during 2010. Dabigatran etexilate was administered for the prevention of venous thromboembolism after knee arthroplasty in doses of 110 mg in the first 1-4 h after surgery followed by daily doses of 220 mg for 10 days. Patients were examined 3 times and a color Doppler sonography was performed on the 11th day to check for venous thrombosis. Finally, the patients were re-examined at the end of the 1st and the 3rd months postoperatively.
Results: Only one out of 45 patients was diagnosed to have venous thrombosis on sonography done on the 11th day but the patient did not have any symptoms and repeat sonographies at the end of the 1st and the 3rd months postoperatively showed no venous thrombosis either. No complications were witnessed in the patients in the 3-month follow-up period.
Conclusion: Dabigatran etexilate (220 mg/d for 10 days) can be an effective drug against venous thrombosis after total knee replacement surgeries.

Abstract
Background: Short-stem prosthesis for total hip arthroplasty (THA) have been designed to overcome the weakness of standard-stem prostheses and improve surgical outcomes. The aim of this study was to compare short-stem with standard-stem prosthesis outcomes.
Methods: This study was performed as a randomized clinical trial. Subjects were selected among patients referred to Sina University Hospital, Tehran, Iran from April 2010 to 2012. THA were performed with short-stem or standard-stem prostheses after obtaining written informed consent from patients. Balanced block randomization method was used to get a random sample in each group. Clinical outcomes were evaluated based on Harris Hip Score (HHS). Patients were followed up for at least one year. All patients were examined at 2 weeks, 6 weeks, 3 months, 6 months and one year after surgery. In each visit, Control X-ray was obtained and bone and prosthetic position were assessed. Also, the symptoms such as infection, pain, claudication, ability to climb stairs, using crutches and weight bearing were rechecked. Student t-test was used to compare outcomes in the two groups.
Results: A total of eighty four THA were studied. 13 patients were lost to follow-up or had infection and failure. One patient died with the prosthesis in situ from causes not related to the surgery. Therefore, a total of 70 patients were analyzed. Of these, 34 and 36 hips underwent small stem and standard stem THA, respectively. The mean age of the patients at the time of operation was 61.1±8.68 years (range, 48-86 years). Most common reasons for arthroplasty were osteoarthritis, avascular necrosis and dysplasia of hip. There were significant differences between the two study groups in bleeding during surgery (P=0.001). There were no significant differences among the study groups in HHS except for 6th week and 3th month (P=0.000).
Conclusion: The use of short-stem prosthesis can improve the performance of patients in short-term but no significant difference with standard-stem prosthesis in long- term.

Abstract
Background: The patient's position during the recovery time after arthroplasty surgery can be a factor in reducing complications and improving patients’ condition. Therefore, this study was performed to compare the knee range of motion after soft tissue repair in both flexion and extension positions of total knee arthroplasty.
Methods: This study is a double-blind clinical trial. The study population was all candidates for total knee arthroplasty surgery in Al-Zahra and Kashani hospitals in Isfahan from July 2011 to September 2012. The sample size was selected using the statistical formula of 88 patients and randomly divided into two groups of flexion and extension. In the first group during the knee soft tissue repair, the knee was in flexion and in the second group it was in extension and then it was repaired. Information such as age, sex, body mass index and surgical position were recorded in the checklist. The knee range of motion was measured at the end of the first, second, fourth, eighth and twelfth weeks and recorded in a checklist. In order to compare the pattern of changes in mean knee range of motion over time in the two groups, mixed linear models and conventional marginal models to generalized estimator equations were used by STATA software.
|
Results: The results showed that there was no significant difference between the flexion and extension groups in knee range of motion. In both groups, the mean knee range of motion increased with time (P<0.001). The mean scores of knee function after the end of the twelfth week in the flexion and extension groups were 141.04±23.19 and 143.09±22.34, respectively, and this difference was not significant.
Conclusion: Soft tissue repair in a particular position is not so effective on the outcome that we want to institutionalize it by spending a considerable amount of budget for training surgeons.
