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: Avascular necrosis (AVN) of femoral head, with resultant joint destruction, is a common disabling disease of fourth and fifth decades of life. Metal-on-metal resurfacing is a relatively newer treatment modality for this disease. The aim of this study is to compare the result of resurfacing for osteonecrosis with that of resurfacing for other causes.Methods: Twenty eight patients with stage III or IV (Ficat & Arlet) osteonecrosis who underwent metal-on- metal hip resurfacing were compared with 24 cases of grade IV or V (Croft’s) osteoarthritis (OA) who had undergone the same kind of arthroplasty during a 2 year period in Akhtar hospital in Tehran. These cases were matched in terms of gender and age, and were assessed by Harris hip score with 41(±22) months follow-up.Results: The AVN cases had 30.86 (±7.5) and OA cases 47.88 (±12.6) years at surgery. Three patients from each of the above groups had sustained complications of either femoral neck or acetabular cup fracture and had required revision surgery. The average Harris hip score was 94(±7.2) in AVN and 91.2(±9.4) in OA group. The collective hip range of motion was 216(±6.2) in AVN and 196±(5.6) in AO patients.Conclusions: Metal-on-metal hip resurfacing gives similar satisfactory results in avascular necrosis and in osteoarthritis of hip joint in short-term, with no statistically significant difference.

Background: Osteoarthritis is a relatively common ailment of human beings. The aim of this study is to compare the short-term effects of oral non-steroid anti-inflammatory medications with intra-articular injections of Hyaluronic Acid or Methyl Prednisolone acetate.Methods: In a clinical trial study, 40 female patients with moderate or severe knee osteoarthritis received Hyaluronic Acid intra-articular injections. They were compared with 16 cases who had intra-articular Prednisolone injection and 36 female patients who received non-steroid anti-inflammatory oral medication. The results were evaluated in 6 and 24 weeks by Visual Analogue Scale and Western Ontario & McMaster Universities (WOMAC) functional score.Results: Pain relief in 6 and 24 weeks post injection were 4.9 and 4.7 for Hyaluronic Acid, and 1.5 and 1.6 for Prednisolone. The figures for oral non-steroidal anti-inflammatory medication were 5.2 and 4.9 respectively. Subjective patient’s satisfaction was expressed in 28 (70%) of Hyaluronic Acid group and 16 (100%) of Prednisolone group.Conclusions: After 6 and 24 weeks following intra-articular steroid injection in female patients with knee osteoarthritis, pain relief and subjective patient satisfaction is more favorable compared to intra-articular Hyaluronic Acid injection. These two are both more effective than oral anti-inflammatories. This statement does not include the potential side-effects of intra-articular steroid injection in long-term.

Methods: In a case series study, cases of osteonecrosis in Akhtar hospital in Tehran with history of temgesic and norgesic abuse were identified in a 2 year period. The hospital charts of 11 cases with such characteristics were evaluated.Results: Eleven cases with mean age of 37.72±5.55 years comprised the study group. Five cases had used norgesic, 5 temgesic and 1 patient had used both of those agents. The average drug dosage was 4.36±2.29 vials per day for an average of 4.9±2.9 months. Onset of symptoms was 11.36±2.76 months after drug usage on average. Three cases had skin stria and 7 patients had localized obesity, both suggesting steroid effect. Bilateral involvement of bone ends was observed in all, while 3 cases had more than two joints affected.Conclusions: Norgesic and temgesic cause osteonecrosis with severe joint destruction. Raising the awareness of general public and physicians towards such a devastating complication is warranted.
