BACKGROUND: The purpose of this observational study was to evaluate serum levels of 25-OH-D in patients scheduled to undergo elective hip or knee arthroplasty. We hypothesised that 25-OH-D level is an independent risk factor for length of stay in orthopaedic patients after elective hip or knee arthoplasty. MATERIALS AND METHODS: 25-OH-D levels were measured in 1083 patients admitted to an orthopaedic surgery department to undergo elective hip or knee arthroplasty...

OBJECTIVE: This study compared three methods of surgical wound dressing in patients undergoing primary total hip arthroplasty to determine their effect on wound leakage. METHOD: Total hip arthroplasties were randomised to 3 groups: 2-octyl cyanoacrylate (Dermabond-Ethicon Inc, G) with Opsite (Smith & Nephew; O) [G+O], 2-octyl cyanoacrylate with Tegaderm (3M; T) [G+T], and Opsite without 2-octyl cyanoacrylate [O]. Postoperative wound leakage was assessed and graded daily until discharge, the frequency of the dressing changes was also recorded...

BACKGROUND: Hemodynamic optimization during surgery is of major importance to decrease postoperative morbidity and length of hospital stay. However, conventional cardiac output monitoring is rarely used at the bedside. Recently, the plethysmographic variability index (PVI) was described as a simplified alternative, using plug-and-play noninvasive technology, but its clinical utility remains to be established. METHODS/DESIGN: The hemodynamic optimization using the PVI (OPVI) trial is a multicenter randomized controlled two-arm trial, randomizing 440 patients at intermediate risk of postoperative complications after orthopedic surgery...

PURPOSE: Severe cases of osteoarthritis with ligamentous instability require the use of a modular knee arthoplasty. To assess the survival, the complications, the clinical, radiological and functional outcomes, and the quality of life of those patients in whom a Optetrak Condylar Constrained Knee (CCK) had been implanted as a primary implant. To study how the pre-operative conditions (deformity, age, sex …) and the characteristics of the arthroplasty (stems, supplements, constrained component …) could change the survival or the clinical outcomes of the implants...

Metallosis is serious condition that comes about when metallic debris builds up in the soft tissues of the body. This condition is seen in individuals undergoing joint replacement surgery, like those of the hip, knee and elbow. Incidence of metallosis is not common. Here we present a case of 61 year-old male, who had undergone right-sided total hip replacement 20 years earlier due to avascular necrosis. He presented to us with one-year history of massive swelling of right thigh and mild pain and discomfort in September 2013...

BACKGROUND/AIM: Infection following total hip arthroplasty (THA) or total knee arthoplasty (TKA) may have devastating consequences. Some bacterial strains are often encountered as agents of these infections, others occur less frequently but are sometimes burdened with more severe complications. Kebsiella spp. are uncommon causes of THA or TKA infection. The aim of this study was to identify an effective treatment algorithm for multidrug resistant Kebsiella spp. caused THA or TKA infections...

BACKGROUND AND PURPOSE: There is an increase in demand for primary and revision total knee joint procedures. We studied implant survival and functional outcome of patients operated with a constrained condylar knee (CCK) or a rotating hinge implant (RH) as a primary or a revision total knee arthoplasty (TKA). PATIENTS AND METHODS: We evaluated clinically and radiographically 65 surgical procedures with a mean follow-up time of 5 (2-9) years (40 CCK and 25 RH). There were 24 primary TKAs-due to instability-and 41 revision TKAs, mostly due to aseptic loosening...

Total knee arthoplasty has been accepted as a valuable adjunct in the treatment of knees severely compromised by disease or trauma. One hundred nine geometric total knee replacements were reviewed to determine the efficacy of the device in the relief of pain, the correction of deformity and instability, and the restoration of functional motion in the diseased knee.1.

In comparison with standard surgical techniques robotic-assisted surgery has the advantages of increased surgical accuracy, reproducibility, optimization of component position, and improved patient outcomes in unicompartmental knee arthroplasty (UKA) and total hip arthoplasty (THA) procedures. The MAKO Tactile Guidance System (TGS; MAKO Surgical Corp, Fort Lauderdale, FL) facilitates robotic-assisted arthroplasty procedures currently implemented in many operating rooms. The benefits of this technology are evident, but have not been shown to improve patient outcomes and justify the added financial burden imposed...

In the past decade, there has been a major increase in the use of unicompartmental knee arthroplasty (UKA) as surgical techniques have been refined and patient selection has improved. UKAs now account for 8% to 10% of knee arthoplasty procedures. Recent studies have suggested excellent medium- and long-term results of UKA. Overall, results have shown 85% to 90% survivorship at 10 years, with 90% of patients reporting good to excellent subjective and objective outcomes. Recent studies suggest that unicompartmental arthroplasty allows a high percentage of patients to return to presurgical sport and activity participation...

PURPOSE: Despite providing adequate pain relief, a femoral nerve block can induce postoperative muscle weakness after total knee arthoplasty (TKA). Fentanyl has been shown to have peripheral effects but has not been used as a perineural infusate alone after TKA. METHODS: Sixty patients scheduled for TKA were randomized to one of three blinded groups: a continuous 24 h infusion of either fentanyl 3 μg/ml, ropivacaine 0.1%, or 0.9% normal saline through a femoral nerve sheath catheter at 10 ml/h...

BACKGROUND: Some follow-up studies of high flexion total knee arthoplasties report disturbingly high incidences of femoral component loosening. Femoral implant fixation is dependant on two interfaces: the cement-implant and the cement-bone interface. The present finite-element model (FEM) is the first to analyse both the cement-implant interface and cement-bone interface. The cement-bone interface is divided into cement-cancellous and cement-cortical bone interfaces, each having their own strength values...

Achieving high flexion is an objective of contemporary total knee arthoplasty; however little is known on the knee biomechanics at high flexion under weight-bearing conditions. This study investigates the 6DOF kinematics and tibiofemoral cartilage contact biomechanics of the knee during weight-bearing flexion from full extension to maximal flexion. Eight knees from seven healthy subjects with no history of injuries or chronic pain were recruited. The knees were MRI scanned to create 3D models of the tibia and femur, including their articular cartilage surfaces...

Total hip arthroplasty in patients with previous above knee amputations is rare. We present a unique case where the patient had only 130 mm of proximal femur remaining following a previous traumatic above knee amputation. The short segment of femur meaning a conventional femoral stem could not be used. We describe the technique of total hip arthoplasty for this patient using a mini hip prosthesis and report a successful clinical and radiological outcome at 2 years post-op.
