Background: Posterior tibial slope is the normal anteroposterior inclination of the tibia slope and plays an important role in the biomechanics of the knee and function of the cruciate ligaments. Posterior tibial slope angle varies in different populations and there is no report about its measurement in the Iranian population. The aim of this study was to investigate the normal posterior tibial slope in a teaching hospital in Tehran-Iran. Methods: In a desreptive study, 108 knees in 70 men and 38 female patients, with no history of prior knee problem were evaluated by lateral knee rodiographs in a teaching hospital in Tehran-Iran. The average age in these cases was 38 years (23-60 years). These patients had refered because of recent knee trauma, but no fracture or intra-articular derangement had been found. The angle of tibial slope was measured in all the cases and analyzed. Results: The mean slope angle was 9.4±1.8 degrees. There was no statistical relationship between age and gender and posterior tibial slope (p≥.05). Conclusion: The normal posterior tibial slope angle in this Iranian population was different from other countries. It may be necessary to consider these differences in designing tibial and femoral components for knee arthroplasty.

Background: The role of increased posterior tibial slope in rupture of the anterior cruciate ligament (ACL) is controversial. The purpose of current study was to determine the effect of posterior slope on the ACL injury. Methods: In a case control study, 61 consecutive cases with ACL injury, who were candidates for reconstruction, were compared with 61 persons with normal knees who were matched for age and sex, over a 2-year period at a teaching hospital in Tehran, Iran. The posterior tibial slope angles were measured on true lateral radiographs on all the cases. The measurement variations were analyzed between the two groups. Results: The mean posterior tibial slope was 9.4±1.8 degrees in controls and 12.3±4.4 in patients with ruptured ACL (p < .001). The incidence of tibial slope greater than 10 degrees in patients with ruptured ACL was 3.1 times greater than that of the controls. Conclusion: This study suggests that increased tibial slope angle may contribute to increased risk for ACL rupture.

Background: Hip fracture in older population is frequent and often costly. The patients, however, do not commonly regain their pre-fracture activity levels. We are reporting the outcome of surgery in intertrochanteric hip fractures during a ten-year period.Methods: This is a retrospective study of the intertrochanteric hip fractures treated from 1994 to 2004 in one teaching hospital of Tehran-Iran. The cases were called in for a full hip examination, evaluation of their activity levels and also measurement of Harris Hip Scores (HHS), as well as radiographic assessment.Results: 293 patients, comprised of 194 males (66.2%) and 99 females (33.9%), with a mean age of 65±6.67 years were studied. The cases had a one-year of follow-up. 252 (86%) cases had obtained :::union:::. Acceptable ligament was observed in 158 (54%) cases. Harris Hip Scores over 60 points was seen in 222 (75.8%). Only 90 patients had returned to their pre-operative activity level.Conclusion: Patients with intertrochanteric hip fracture do not often return to pre-fracture activity of daily living.

Background: Prior to 1980 decade, surgical ideas and facts were mainly based on the individual surgeon’s experience and the collective judgment of groups of surgeons. In the 1980’s the concept of “Evidence Based Medicine” became popular suggesting that all surgical practices must be based on evidence and not experience. According to the widespread publication of medical articles nowadays, the question often arises about the dependability and strength of the evidence. We are reporting the level of evidence (LOE) of articles published in the Journal of the Iranian Orthopaedic Association between 1995 and 2008. Methods: All the articles published in the Iranian Journal of Orthopaedic Surgery (1995-2008) were studied separately by 5 groups of physicians. The level of evidence rating system was based on the Journal of Bone and Joint Surgery, which classifies articles into therapeutic, prognostic, diagnostic and economic subgroups. The articles are subsequently divided into five levels in accordance with the defined levels of evidence.Results: Over half of the articles (54%) were therapeutic, 9% diagnostic, 35% prognostic and 2% economic. Overall 2% were placed as level I, 8% level II, 5% level III, 84% level IV and 1% level V.Conclusion: Therapeutic and prognostic articles and evidence level IV were the most common types observable in the articles published in the Iranian Journal of Orthopaedic Surgery. Furthermore, level I to III articles in this journal had increased over 3.5 times between 1995 and 2008.
