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 anterior cruciate ligament is the primary structure that controls anterior displacement in the unloaded knee. Anterior cruciate ligament reconstruction may return normal functions of the knee. The aim of the present study was to compare three different femoral fixation techniques in anterior cruciate ligament reconstruction.Methods: In a clinical trial study, 120 patients that were candidates for ACL reconstraution were randomly divided into 3 groups of 40 individuals. The femoral fixations were by the three methods of "Aperfix", "Rigidfix" or "Endobutton". The cases were re-examined 12 months after surgery and evaluated by Lysholm score as well as with KT-1000 machine. The results were compered together for the three above methods.Results: The Lysholm score showed improvement from pre-operative values in all three techniques: From 63.21±18.59 to 90.64±9.47 in "Endobutton" group, from 65.72±18.74 to 96.22±5.35 in "Aperfix" and from 69.21±17.45 to 90.64±9.47 in the "Rigifix" group. There were 6 failures in "Endobutton", 4 in "Rigidfix" and one in "Aperfix" group. The anterior displacement tibia was 3.96±1.58 millimeters in "Endobutton", 4.28±1.48 in "Rigidfix", and 4.03±1.79 millimeters in "Aperfix" group. There was no significant difference in the operating time in the 3 groups.Conclusion: Regarding the instant stability of the graft, the "Aperfix" method seemed stranger. Further investigations with larger number of cases and longer duration of follow up are recommended.

Background: Unstable pelvic fractures are major orthopaedic injuries with high rates of morbidity and mortality. Open surgical stabilization is the standard treatment for a great number of them. Percutaneous surgical fixation has become an accepted treatment method in last several years. We would like to report our experience with this relatively, newer technique in a small mixed group of unstable pelvic ring fractures.Methods: This is a report of 16 cases (13 males, 3 females) with mean age of 31±8 years of pelvic and acetabular fractures who received percutaneous iliosacral or iliopubic screw fixation, under C-arm imaging control, and had a 6 months period of clinical and radiographic follow-up.Results: All 16 cases had healed their fractures at follow-up and had full weight-bearing status. 12 cases returned to their pre-fracture activities. One screw break and one wound infection were the complications list. There was no neurological deficit, and average blood loss was 10 milliliters.Conclusion: Percutaneous iliosacral or iliopubic screw fixation for, respectively, posterior pelvic ring or anterior column acetabular injuries are useful surgical treatment options with low complication rates.

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: The role of a mobile-bearing knee arthroplasty is still not clear. This study was designed to compare the mobile and fixed-bearing prosthesis.Methods: In 30 knees a fixed-bearing and in 38 knees a mobile-bearing prosthesis was used. The results were compared using the "Knee Society Scoring System".Results: The mobile-bearing group of patients had an average age of 65 and 34 months average follow-up. The fixed-bearing group had an average age of 69 years and a mean follow-up of 30 months. The average knee score, functional score and overall score in the mobile-bearing group rose from 29, 45, 73 to 64, 67, 128 and in the fixed-bearing group from 31.7, 34, 65.9 to 68, 57, 125 prospectively. The difference between two groups was not significant statistically.Conclusion: Although in both groups the average knee scores increased after the operation, there were, however, no significant difference between knee scores in the two types in short-term, and no preference between two types of prosthesis.
