BACKGROUND Surgical navigation in TKA facilitates better alignment; however, it is unclear whether improved alignment alters clinical evolution and midterm and long-term complication rates. QUESTIONS/PURPOSES We determined the alignment differences between patients with standard, manual, jig-based TKAs and patients with navigation-based TKAs, and whether(More)
BACKGROUND Minimal invasion surgery (MIS) is a recent technique recommended for Total knee arthroplasty (TKA) but demands an effort of the surgeons and the learning curve may be long. METHODS Twenty six MIS-TKA were matched to 36 standard TKA with respect to age, sex, body mass index or preoperative score. All patients suffered from knee osteoarthritis,(More)
BACKGROUND The first stage in the implant of a total knee arthroplasty with computer-assisted surgery is to fasten the emitters to the femur and the tibia. These trackers must be hard-fixed to the bone. The objectives of our study are to evaluate the technical problems and complications of these tracker-pins, the necessary time to fix them to the bone and(More)
est de 77,5%. Pour 7 cas (11,3%) parmi lesquels 5 ont été réopérés, on a noté une mobilisation cotyloïdienne accompagnée de douleurs et de boiterie. Chez 28 autres patients, on a noté des liserés péri-prothétiques supérieurs à 1 mm dont 7 (11,3%) étaient évolutifs avec une augmentation d’épaisseur sur les radiographies successives. L’arthrose avant(More)
We studied 47 reverse oblique intertrochanteric femoral fractures that were treated with gamma nails between 1992 and 2000. Fracture reduction was satisfactory in 38 patients (81%), the hip screw position was correct in 42 (89%) and there were no peri-operative complications. However, in three patients the nail displaced, resulting in non-union in one and(More)
BACKGROUND Measured bone density correlates well with the mechanical properties of the bone. Our objective was to evaluate optical densitometry as a method of measuring the periprosthetic bone density of the tibial platform in total knee replacement using serial dual-energy X-ray absorptiometry (DXA) as the reference test. METHODS 30 patients who(More)
BACKGROUND Some studies have raised the question about whether the good results obtained with the Charnley prosthesis could be replicated at general hospitals when it comes to the frequency of early complications and failure rates, both of which would be higher than those published by centres devoted to hip arthroplasties. METHODS We reviewed the results(More)
BACKGROUND The accuracy of computer navigation applied to total knee arthroplasty (TKA) in knees with severe deformity has not been studied. QUESTIONS/PURPOSES The purpose of this study was to compare the radiographic alignment achieved in total knee replacements performed with and without navigation and to search for differences in the final alignment of(More)
AIM To compare the safety and effect on tibial diaphyseal fracture bone union of two intramedullary nailing techniques: (1) dynamic locking with early, full weight bearing, and (2) static locking with delayed weight bearing until bone union. PATIENTS AND METHODS This is a retrospective case-control study of closed or type I open tibial diaphyseal(More)
We describe a case of navigation-aided knee arthrodesis in a patient with a previous femoral deformity. Because of the complex deformity and the foreseeable difficulties in obtaining correct limb mechanical axis, a wireless navigation system was used to perform cuts of the distal femur and proximal tibia in both the coronal and sagittal planes. For a stable(More)
