Arthroscopic ACL Reconstruction with Bone Patellar Bone Graft using Anteromedial Technique
There are approximately 200,000 anterior cruciate ligament (ACL) injuries per year in the United States and more than half will undergo ACL reconstruction. Diagnosis is made by physical exam supplemented by radiographs and an MRI scan. Successful ACL reconstruction returns most athletes back to pre injury activity, however, outcome is dependent on appropriate preoperative evaluation, surgical timing, surgical technique, graft choice and an effective postoperative physical therapy program.
Bilateral Simultaneous Anterior Cruciate Ligament Injury: A Case Report and National Survey of Orthopedic Surgeon Management Preference
Unilateral anterior cruciate ligament (ACL) tear is a common injury seen by sports medi-cine orthopedic surgeons. However, a bilateral simultaneous ACL injury is extremely rare and has been reported only three times in the liter-ature. We present a young female skier with simultaneous bilateral ACL tears that were managed with staged ACL reconstruction. We then conducted a nationwide survey (United States) to determine the...
Needle assisted arthroscopic clysis of the medial collateral ligament of the knee: a simple technique to improve exposure in arthroscopic knee surgery
During knee arthroscopy, narrowness and tightness maybe encountered in the medial compartment that does not allow sufficient visualization or instrumentation. When this occurs, our team has found it helpful to per-form a percutaneous clysis of the deep portion of the medial collateral ligament with a spinal needle. With the knee...
Surgical Treatment of a Chronically Fixed Lateral Patella Dislocation in an Adolescent Patient
Acute patellar dislocation or subluxation is a common cause for knee injuries in the United States and accounts for 2% to 3% of all injuries. Up to 49% of patients will have recurrent subluxations or dislocations. Importance of both soft tissue (predominantly, the medial patellofemoral ligament, MPFL, which is responsible for 60% of the resistance...
Evaluation of sterilization methods following contamination of hamstring autograft during anterior cruciate ligament reconstruction
PURPOSE: Inadvertent contamination of the hamstring autograft during ACL reconstruction is infrequent, but can result in significant complications. The purpose of this study is to evaluate bacterial contamination of hamstring autografts dropped onto the operating room floor and methods of graft decontamination.
Entrapped periosteum preventing reduction of a Salter-Harris II distal tibial fracture in an adolescent patient. MRI and intra-operative findings
INTRODUCTION Physeal or growth plate injuries comprise 18% of all pediatric fractures, with Salter Harris type II as the most common type of fracture injury pattern ob-served in 61% of patients.The incidence of growth arrest is just over 1%, and the incidence of serious complications is less than 1%. Irreducible physeal fractures...
Biomechanical investigation of a novel ratcheting arthrodesis nail
Knee or tibiotalocalcaneal arthrodesis is a salvage procedure, often with unacceptable rates of nonunion. Basic science of fracture healing suggests that compression across a fusion site may decrease nonunion. A novel ratcheting arthrodesis nail designed to improve dynamic compression is mechanically tested in comparison to
Medial patellofemoral ligament injury patterns and associated pathology in lateral patella dislocation: An MRI study
Lateral Patella dislocations are common injuries seen in the active and young adult populations. Our study focus was to evaluate medial patellofemoral ligament (MPFL) injury patterns and associated knee pathology using Magnetic Resonance Imaging studies. MRI studies taken at one imaging site between January, 2007 to January...
