PURPOSE Manufacturers of total knee arthroplasty (TKA) have introduced narrower femurs to improve bone-implant fit. However, few studies have reported the clinical consequences of mediolateral oversizing. Our hypothesis was that component oversizing negatively influences the results after TKA. METHODS One hundred and twelve prospectively followed patients(More)
BACKGROUND Despite the appearance of new-generation, mobile-bearing, cementless prostheses, total ankle arthroplasty remains controversial. Among the criteria guiding the choice between arthrodesis and arthroplasty, the long-term survival and postoperative function are of critical importance. The mobile-bearing Salto prosthesis has been used in Europe since(More)
To analyze the morphology of the tibial plateau, we studied 100 computed tomographic scans of arthritic knees and measured the mediolateral (ML) and anteroposterior (AP) dimensions as well as their aspect ratio using 3 reference axes of rotation: transepicondylar axis (TEA), posterior tibial margin (PTM), and anterior tibial tuberosity (ATT) axis. Relative(More)
In young and active patients, closing-wedge high tibial osteotomies are reliable procedures in the treatment of osteoarthritis of the medial compartment of the knee. This has been consistently shown throughout the last 2 decades. The present study analyzes the long-term results of 217 patients after an average of 9 years and compares them to the results in(More)
UNLABELLED The objective of this study is to investigate the results of total knee arthroplasty (TKA) in traumatic osteoarthritis cases with flexion restriction and to describe the technical details of their management. A multicentre series comprising 40 patients with limitation of flexion less than or equal to 90° was selected from 152 cases of(More)
The Salto Total Ankle Prosthesis is noncemented with mobile bearings and is characterized by an anatomic design and a dual Ti-HA coating. Between 1997 and 2000, 98 consecutive Salto prostheses were implanted. At last followup, two patients were deceased, one patient was lost to followup, and two prostheses were removed in two patients. Ninety-three implants(More)
PURPOSE Residual pain during activities of daily living and/or at rest is a major cause of a patient's dissatisfaction after total knee arthroplasty (TKA). The management of a painful TKA, which has no obvious clinical or radiological explanation, requires further investigation with more sensitive imaging modalities (CT scan and bone scan) and hematological(More)
The purpose of this study was to evaluate the results of arthroscopy of the ankle. Of the 114 arthroscopies of the ankle that we performed between 1991 and 1996, 13 were for diagnosis, 6 were associated with open surgery, and 10 were ankle arthrodeses. We report the results of the remaining 85 therapeutic arthroscopies. We identified five groups according(More)
BACKGROUND During total hip arthroplasty (THA), medialisation of the cup decreases the lever arm of body weight and is considered to be beneficial. Theoretically it should be compensated by an equivalent increase of the femoral offset in order to maintain global offset. GOAL OF THE STUDY We investigated via a numerical model the forces on each bundle of(More)
OBJECTIVES After more than 10 years' experience in France, the French Foot Surgery Association (Association française de chirurgie du pied [AFCP]) presents an update on mobile-bearing ankle prostheses, based on a multicenter study. META-ANALYSIS - BIOMECHANICS - ASSESSMENT AND INDICATIONS: A preliminary comparative meta-analysis of the literature studies on(More)
