Function and sport participation was analyzed via a self-administered questionnaire in 347 patients with unilateral noncomplicated TKA. It was 227 women and 120 men with a mean age of 75 (range, 28 to 94) and a mean follow-up of 44 months (range 13–71). Two hundred and thirty-seven patients (68%) reported that their knee was “normal”, 56% that their(More)
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. One hundred and twelve prospectively followed patients with 114(More)
OBJECTIVE To study the relationship between flat foot and forefoot deformities in rheumatoid arthritis (RA) in order to improve understanding of the progression of deformity and thus provide more appropriate treatment. METHODS Anteroposterior and lateral weight-bearing radiographs were obtained of 308 feet of patients with RA and 202 feet of patients with(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)
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)
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)
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)
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 tests.(More)
Between 1993 and 1995, we operated on 18 patients for split lesions of the peroneal brevis tendon associated with chronic ankle instability. Five patients were competitive athletes, seven were recreational athletes, and six were persons. Symptoms developed in three phases: ankle sprain, chronic instability, and posterolateral pain. The mean delay between(More)
BACKGROUND Recent technological advancements in total ankle arthroplasty (TAA) have included the introduction of the mobile bearing concept. This bearing has several advantages, but researchers have questioned whether or not increased mobility sacrifices joint stability or durability of the implant. The present study evaluated the kinematics of this type of(More)
