Anterior Cruciate Ligament Reconstruction with Hamstring Tendons Has no Deleterious Effect on Hip Extension Strength
Abstract
Background: Hamstring tendons are secondary hip extensors. Their harvest for graft in anterior cruciate ligament (ACL) reconstruction may create deleterious effect on hip extension strength. This is of particular importance in sports that need powerful hip extension force like climbing and sprinting. Due to scarcity of a comprehensive study in this area, we designed this prospective study to evaluate hip extension strength
following ACL reconstruction using different types of grafts
Femoral tunnel widening after hamstring tendon autograft: Endobutton technique vs Double Cross-Pin technique
Abstract
Background/aim An anterior cruciate ligament (ACL) rupture is a common sports-related injury requiring surgical intervention. With the advent of arthroscopically-assisted knee surgery, many graft fixation techniques for ACL have been developed. Femoral tunnel widening has been reported with a different incidence in various fixation techniques however its clinical significance is still not clear
Infected Total Knee Arthroplasty by Brucella melitensis: A Rare Case Report
Abstract
ntroduction Brucellosis is a zoonotic infectious disease with worldwide distribution, especially in the south and central American countries, the Middle-East and the Mediterranean areas. Knee prosthesis infection due to Brucella spp. is very rare with the first case reported in 1991 and the ninth case reported in 2010. Case Presentation Here is reported a case of a 68-year-old female patient, referring to Shafa Orthopedic hospital, Tehran, Iran, complaining about a discharge from right total knee arthroplasty. All of the knee joint aspirations and
laboratory tests were negative for infection
Total Knee Arthroplasty in Patients With Valgus Deformity
Abstract
Background Valgus deformity (more than 10° valgus on anatomical measurement) is seen in about 10% of patients undergoing total knee arthroplasty (TKA). Valgus deformity is a challenge for the surgeons both for gap balancing and constraint choice. Objectives The aim of this study was to describe a surgical technique to perform TKA in valgus knee. Patients and Methods We retrospectively reviewed 32 primary TKA in 27 patients (25 females and 2 males), with valgus knee deformity performed since 2006 to 2014. All procedures have been done by the senior author. In the balancing stage of each procedure, the iliotibial band has been released completely in the first step, and then step by step pie crusting of other lateral structures has been done as needed. Preoperative and postoperative data were obtained retrospectively through chart review and review of radiographs
An Unusual Location of Ossified Intramuscular Lipoma: A Case Report
Abstract
Lipoma is the most common soft tissue tumor but the presence of osseous component within the tumor is quite rare. Some studies show that less than 1% of lipomas were ossified. We describe the histological, radiological and diagnostic features of an ossified intramuscular lipoma. To the best of the authors’ knowledge, a symptomatic ossified intramuscular lipoma without any cortical erosion and hyperostosis has not been previously reported in the literature. © ۲۰۱۱ Tehran University of Medical Sciences.

Neglected triceps tendon avulsion: case report, literature review, and a new repair method
Abstract
Triceps tendon rupture or avulsion is a rare tendon injury. The most common feature of injury is avulsion from osseous insertion on the olecranon. The diagnosis of acute triceps tendon rupture may be missed, and a missed diagnosis can result in prolonged disability and delayed operative management. In this article, we report 2 cases of neglected triceps tendon avulsion and a new V-Y-plasty surgical technique for repair
Osteoid osteoma with an atypical nidus: A case report
Abstract
Osteoid osteoma is a benign tumor that can be seen in both cortical or cancellous bone. Radiographic appearance is usually diagnostic. It consists of a small nidus usually less than 1.5cm and a surrounding bony sclerosis. We present one case of osteoid osteoma with an unusual (nearly completely calcified) nidus
Preoperative pulmonary function tests in different surgical approaches of adolescent idiopathic scoliosis
Abstract
Background: Scoliosis is one of the most common spinal deformities with subsequent decrease in pulmonary function. The effects of surgical correction on the pulmonary function of patients with adolescent idiopathic scoliosis are controversial. The purpose of the present study was to compare the postoperative pulmonary function changes in different surgical approaches chosen for its correction. Methods: Sixty-five patients with adolescent idiopathic scoliosis who had undergone corrective spinal surgery in Shafa Yahyaian Hospital since 1997 to 2007 and had documented preoperative pulmonary function test report, included in our study
