Standing full-length radiographs were measured to compare coronal femoral axes between 250 limbs in patients with varus osteoarthritis with 50 healthy controls. Mean distal femoral axis-mechanical axis angle was 7.3 degrees +/- 1.6 degrees , and mean femoral bow was 3.6 degrees +/- 2.5 degrees in patients compared to 5.5 degrees +/- 0.8 degrees and 0.4(More)
Degenerative changes in the cervical spinal column are ubiquitous in the adult population, but infrequently symptomatic. The evaluation of patients with symptoms is facilitated by classifying the resulting clinical syndromes into axial neck pain, cervical radiculopathy, cervical myelopathy, or a combination of these conditions. Although most patients with(More)
We prospectively evaluated 100 consecutive unicompartmental knee arthroplasties, performed in minimally invasive quadriceps-sparing fashion, for medial compartment osteoarthritis in patients aged 46 to 79 years, with anteromedial tibial wear, less than 10 degrees of flexion contracture, correctable varus not exceeding 15 degrees , and an intact anterior(More)
Tibial articular cartilage wear was assessed intraoperatively in 100 consecutive patients with varus osteoarthritis undergoing total knee arthroplasty. Severity of deformity on radiographs, integrity of the anterior cruciate ligament (ACL) at surgery, and body mass index were recorded. Posterior half of the medial tibial plateau was more commonly involved(More)
BACKGROUND Although cervical spine pedicle screws have been shown to provide excellent fixation, widespread acceptance of their use is limited because of the risk of injury to the spinal cord, nerve roots, and vertebral arteries. The risks of pedicle screw insertion in the cervical spine can be mitigated by a three-dimensional appreciation of pedicle(More)
A novel sequence of posteromedial release consistent with surgical technique of total knee arthroplasty was performed in 15 cadaveric knees. Medial and lateral flexion and extension gaps were measured after each step of the release using a computed tomography-free computer navigation system. A spring-loaded distractor and a manual distractor were used to(More)
STUDY DESIGN Population-based database analysis. OBJECTIVE To analyze trends in patient- and healthcare-system-related characteristics, utilization and outcomes associated with anterior cervical spine fusions. SUMMARY OF BACKGROUND DATA Anterior cervical decompression and spine fusion (ACDF) is one of the most commonly performed surgical procedures of(More)
Total knee arthroplasty was performed in 282 knees with image-free navigation (group A) and in 185 with optimized conventional technique (group B). Mean postoperative mechanical axis of the limb was 179.7 degrees in group A and 179.1 degrees in group B (P < .002). There was a higher percentage of knees in group A that had restoration of mechanical axis to(More)
Thirty primary total hip arthroplasties were performed for protrusio acetabuli in 23 patients (mean age, 46 years) using impacted autologous bone grafting and a cementless porous-coated hemispheric cup without the use of metal cages or rings. At 2 to 10 years' follow-up (mean, 4.2 years), there was satisfactory radiographic evidence of consolidation of the(More)
Anterior cruciate ligaments (ACLs) and posterior cruciate ligaments (PCLs) from 45 osteoarthritic knees were histologically examined to evaluate the frequency and grade the severity of degenerative changes, which were correlated with radiologic grade of arthritis and severity of deformity at the knee. Immunohistochemical staining was used to identify(More)
