Background: Several different methods for fixation of grafts in anterior cruciate ligament (ACL) reconstruction have been used. The purpose of present study is to compare two techniques of tibial fixation in hamstring quadruple graft reconstruction. Methods: In a randomized clinical trial study, 46 cases of isolated tears were reconstructed using hamstring grafts. In 24 cases the tibial fixation sites were fixed with interference screw, and in 22 patients the remnant end of graft at tibia was passed through a bony tunnel and fixed with suture to the bone. The cases were all assessed with a mean follow-up of one year with “Cincinnati knee ligament rating scale” and “KT-2000” examination.Results: The score in 22 “target group” cases was 8, and in 24 “control group” was 9. In “KT-2000” examination, 11 patients of double fixation were excellent and 11 good. In control group 4 cases had excellent and 20 good results (p < /em>=0.01).Conclusions: Double tibial fixation for ACL reconstruction with Hamstring tendon graft has a better outcome on “Symptom” evaluation and “KT-2000” instrument compared to single tibial-site fixation.

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.
