We studied sagittal laxity using the KT1000 arthrometer in 97 total knee arthroplasties (TKAs) in 83 patients using the porous-coated anatomic knee or Duracon TKA (Howmedica, Rutherford, NJ) with 5.4- to 9.9-year follow-up. Two differing tibial inserts were used: flat (group 1) and anteroposterior (AP) lipped (group 2). Greater posterior and total laxity at(More)
BACKGROUND Current literature has shown the mechanism of how indirect fractures occur but has not determined what factors increase the risks of such fractures. The objective of this study is thus to determine the effect of clothing and soft tissue thickness on the risk of indirect fracture formation. METHODS Twenty-five fresh red deer femora embedded in(More)
STUDY DESIGN Retrospective case-referent study. OBJECTIVE To assess whether the new sedimentation sign discriminates between nonspecific low back pain (LBP) and symptomatic lumbar spinal stenosis (LSS). SUMMARY OF BACKGROUND DATA In the diagnosis of LSS, radiologic findings do not always correlate with clinical symptoms, and additional diagnostic signs(More)
OBJECTIVE To evaluate the clinical effectiveness of manual physiotherapy and/or exercise physiotherapy in addition to usual care for patients with osteoarthritis (OA) of the hip or knee. DESIGN In this 2 × 2 factorial randomized controlled trial, 206 adults (mean age 66 years) who met the American College of Rheumatology criteria for hip or knee OA were(More)
STUDY DESIGN An experimental study of cardiovascular complications that arise during vertebroplasty was conducted. OBJECTIVE To investigate the sequential occurrence of fat embolism and hypotension during vertebroplasty. SUMMARY OF BACKGROUND DATA Vertebroplasty, the augmentation of vertebrae with polymethylmethacrylate, is a technique for treating(More)
STUDY DESIGN A case report of Mycobacterium xenopi. OBJECTIVES To present a case report of a vertebral osteomyelitis caused by M. xenopi and to review the world literature on the subject. SUMMARY OF BACKGROUND DATA M. xenopi is most commonly a pulmonary pathogen in immunosuppressed patients or those with underlying lung disease. Infection of the spine(More)
BACKGROUND Non-pharmacological, non-surgical interventions are recommended as the first line of treatment for osteoarthritis (OA) of the hip and knee. There is evidence that exercise therapy is effective for reducing pain and improving function in patients with knee OA, some evidence that exercise therapy is effective for hip OA, and early indications that(More)
Lumbar spinal stenosis is a frequent indication for spinal surgery. The predictive quality of treadmill testing and MRI for diagnostic verification is not yet clearly defined. Aim of the current study was to assess correlations between treadmill testing and MRI findings in the lumbar spine. Twenty-five patients with lumbar spinal stenosis were prospectively(More)
BACKGROUND Most people experience low back pain (LBP) at least once in their lifetime. Only a minority of them go on to develop persistent LBP. However, the socioeconomic costs of persistent LBP significantly exceed the costs of the initial acute LBP episode. AIMS To identify factors that influence the progression of acute LBP to the persistent state at(More)
BACKGROUND Non-sterile disposable gloves are used on large hospital wards, however their potential role as a vehicle for pathogen transmission has not been explored in this setting. AIMS This study investigates glove use on a hospital orthopaedic ward to examine whether pathogen contamination occurs prior to contact with patients. METHOD Glove samples(More)
