BACKGROUND: Anterior cruciate ligament (ACL) reconstruction is frequently performed to restore knee stability and function following ACL injury. Female sex is known to predispose to ACL injury; however, it remains unclear whether female sex predisposes to poor outcomes following ACL reconstruction. We hypothesized that male and female patients exhibit no differences in (1) graft failure risk, (2) contralateral ACL injury risk, (3) knee laxity, and (4) patient-reported outcome scores following ACL reconstruction...

Patient satisfaction is an individual's cognitive evaluation of, and emotional reaction to, his or her health-care experience. This concept is increasing in importance as survey data are being used by health-care facilities for self-assessment, accreditation requirements, and compensation formulas. High patient satisfaction is associated with increased market share, financial gains, decreased malpractice claims, and improved reimbursement rates. Modifiable factors that contribute to satisfaction include physician-patient communication, the setting of appropriate expectations, minimization of waiting times, and provision of continuity of care...

BACKGROUND: Literature guiding the management of early-onset scoliosis consists primarily of studies with a low level of evidence. Evaluation of clinical equipoise (i.e., when there is no known superiority among treatment modalities) allows for prioritization of research efforts. The objective of this study was to evaluate areas of clinical uncertainty among pediatric spine surgeons regarding the treatment of early-onset scoliosis. METHODS: Fourteen experienced pediatric spine surgeons participated in semistructured interviews to identify clinical variables that influence decision making in the treatment of early-onset scoliosis...

BACKGROUND: The objectives of this study were to (1) determine the prevalence of heterotopic ossification after surgery for fractures and fracture-dislocations involving the proximal aspect of the radius or ulna, (2) identify risk factors associated with the development of heterotopic ossification in these injuries, and (3) characterize the severity and location of the heterotopic ossification and the associated range of elbow motion. METHODS: From 2004 to 2008, 142 elbow fractures and fracture-dislocations involving the proximal aspect of the radius or ulna were treated surgically at our institution...

BACKGROUND: Anteroposterior, lateral, and right and left oblique lumbar spine radiographs are often a standard part of the evaluation of children who are clinically suspected of having spondylolysis. Recent concerns regarding radiation exposure and costs have brought the value of oblique radiographs into question. The purpose of the present study was to determine the diagnostic value of oblique views in the diagnosis of spondylolysis. METHODS: Radiographs of fifty adolescents with L5 spondylolysis without spondylolisthesis and fifty controls were retrospectively reviewed...

This update summarizes recent research pertaining to orthopaedic foot and ankle surgery that was published or presented between August 2011 and July 2012. The sources of these studies include The Journal of Bone and Joint Surgery (American and British Volumes); Foot and Ankle International; and the proceedings of Specialty Day at the annual meeting of the American Academy of Orthopaedic Surgeons (AAOS), on February 11, 2012, in San Francisco, California, and the summer meeting of the American Orthopaedic Foot & Ankle Society (AOFAS), on June 20 through 23, 2012, in San Diego, California...

BACKGROUND: In children with spastic diplegia, surgery for ankle equinus contracture is associated with a high prevalence of both overcorrection, which may result in a calcaneal deformity and crouch gait, and recurrent equinus contracture, which may require revision surgery. We sought to determine if conservative surgery for equinus gait, in the context of multilevel surgery, could result in the avoidance of overcorrection and crouch gait as well as an acceptable rate of recurrent equinus contracture at the time of medium-term follow-up...

BACKGROUND: Little is known of the cellular events that occur in native or repaired tendons as a result of immobilization after injury. To examine this issue, we compared (1) native tendons without immobilization, (2) native tendons with immobilization, and (3) surgically repaired tendons with immobilization. METHODS: Eighty-one rats underwent either patellar tendon repair followed by immobilization or immobilization of the native tendon without repair. A custom external fixation device was used for immobilization...

BACKGROUND: MRI (magnetic resonance imaging) is widely used to diagnose meniscal pathology and ACL (anterior cruciate ligament) tears. Because of the enhanced signal-to-noise ratio and improved image quality at higher field strength, knee MRI equipment is shifting from 1.5 to 3.0 T. To date, objective evidence of improved diagnostic ability at 3.0 T is lacking. The purpose of this prospective study was to assess the accuracy of 1.5 and 3.0-T MRI of the knee, in the same individuals, for diagnosing meniscal pathology and ACL tears, utilizing arthroscopy as the reference standard...

BACKGROUND: Rotator cuff-tear arthropathy has traditionally represented a challenge to the shoulder arthroplasty surgeon. The poor results of conventional total shoulder arthroplasty in rotator-cuff-deficient shoulders due to glenoid component loosening have led to hemiarthroplasty being the traditional preferred surgical option. Recently, reverse total shoulder arthroplasty has gained increasing popularity because of a clinical perception of an improved functional outcome, despite the lack of comparative data...

We previously evaluated the three to ten-year results of 160 consecutive unicompartmental knee arthroplasties that had been performed by two surgeons in 147 patients with use of the cemented metal-backed Miller-Galante prosthesis. The average age of the patients at the time of the index procedure was sixty-six years. The purpose of the present study was to report the updated results of this series after a mean duration of follow-up of twenty years. Sixty-two patients (seventy knees) were living, and seven had been lost to follow-up...
