BACKGROUND Dislocation following total knee arthroplasty (TKA) is the worst form of instability. The incidence is from 0.15 to 0.5%. We report six cases of TKA dislocation and analyze the patterns of dislocation and the factors related to each of them. MATERIALS AND METHODS Six patients with dislocation of knee following TKA are reported. The causes for(More)
Treatment of patella infera and arthrofibrosis after total knee replacement (TKR) remains an unsolved problem. Different options have been proposed: patellectomy, proximal transposition of tibial tuberosity, distalization of the femoral component, arthroscopic and open debridment of intraarticular fibrosis. Individual predisposition, mechanical irritation(More)
To analyze the trend of incidence rates of primary total knee (TKA) and primary total hip arthroplasty (THA) due to osteoarthritis among Spanish adults suffering diabetes (type-1 and 2) from 2001 to 2008 and analyze in-hospital mortality (IHM), length of stay (LOS) and hospital charges compared with non-diabetic patients. From the Spanish National Hospital(More)
BACKGROUND Isolated gastrocnemius contracture is thought to lead to numerous conditions. Although many techniques have been described for gastrocnemius recession, potential anesthetic, cosmetic, and wound-related complications can lead to patient dissatisfaction. Open and endoscopic recession techniques require epidural anesthesia, lower limb ischemia, and(More)

OBJECTIVES High-resolution ultrasonography (US) can play an important role in studying nerves, as it has several advantages. Entrapments of distal tibial nerve branches can be mapped out or diagnosed with selective anesthetic blocks, and US can guide therapeutic procedures, such as radiofrequency ablation and selective infiltrations of specific nerve(More)
The standard treatment for late infections of knee prostheses is a two-stage reimplantation with a temporary articulating spacer between operations, but there is no universal agreement as to the best type of spacer to be used and surgeons have created modifications according to their technical and economic resources. We describe our modified technique for(More)
BACKGROUND AND OBJECTIVE An epidemiological association between obesity and asthma has been confirmed, but its possible link to disease control is controversial. The aim of this study was to investigate if asthma control was related with obesity. PATIENTS AND METHODS Asthmatics adult outpatients with good compliance on therapy and correct inhalation(More)
