Total Knee Arthroplasty due to Knee Osteoarthritis: Risk Factors for Persistent Postsurgical Pain.

Objective: The aim of this study was to identify whether different patient characteristics and clinical factors can be risk factors in patients with persistent postsurgical pain (PPSP) after total knee arthroplasty (TKA).

Methods: Patients who underwent TKA due to knee osteoarthritis were divided into two groups: those who experienced no or mild PPSP (Numerical Rating Scale [NRS] ≤ 3) (group 1, n = 91) and those who experienced moderate to severe PPSP (NRS > 3) (group 2, n = 183). Information on the characteristics of patients, comorbid diseases and pre-surgical NRS scores were obtained retrospectively from hospital charts.

Incidence of Infection and Inhospital Mortality in Patients With Chronic Renal Failure After Total Joint Arthroplasty.

Background: Patients with chronic renal failure (CRF) may require total joint arthroplasty (TJA) to treat degenerative joint disease, fractures, osteonecrosis, or amyloid arthropathy. There have been conflicting results, however, regarding outcomes of TJA in patients with chronic renal disease. The aim of this case-controlled study was to determine the outcome of TJA in patients with CRF, with particular interest in the incidence of infections and inhospital mortality.

Background: Recent studies have failed to show reductions in rates of red blood cell (RBC) transfusion after total joint arthroplasty (TJA) in the United States. This study aims to report the 19-year trend analysis of blood use in TJA, to determine predictors of RBC transfusion and association between RBC transfusion and in-hospital mortality after TJA using a nationally representative database.

Study Design And Methods: Nationwide inpatient sample (NIS) data from 1993 to 2011 were used.

Comparison of monoplanar versus biplanar medial opening-wedge high tibial osteotomy techniques for preventing lateral cortex fracture.

Purpose: The purpose of this study was to investigate the mechanical strength of both monoplanar and biplanar medial opening-wedge high tibial osteotomy (MOWHTO) procedures and assess the risk of lateral cortex disruption for both techniques.

Randomized controlled clinical trial.The main purpose of the present study was to comparatively analyze the effectiveness, advantages, and the complications of using semirigid synthetic softcast with respect to plaster of Paris (POP) during the treatment of clubfoot deformity.The study group consisted of 196 babies (249 feet).

A new diagnostic parameter for patellofemoral pain.

Purpose: Q-angle measurement procedure have not been well standardised. There is a lack of consensus about subject position and knee flexion angle while measuring the Q-angle. Morover Q-angle value which obtained in a single position is a static value and gives an information about the subject's current position.

Evaluation of mobile bearing unicompartmental knee arthroplasty, opening wedge, and dome-type high tibial osteotomies for knee arthritis.

Objective: Three methods of surgery used in the treatment of knee osteoarthritis (OA) are mobile bearing unicompartmental knee arthroplasty (Oxford UKA), opening wedge high tibial osteotomy (HTO), and dome-type HTO. This article aimed to retrospectively compare these three methods in terms of outcomes for health status, patient satisfaction, and function.

Methods: Between 2003 and 2010, 255 knees of 235 patients underwent operations for medial knee OA.

Lower extremity rotational deformities and patellofemoral alignment parameters in patients with anterior knee pain.

Purpose: Anterior knee pain is a common musculoskeletal condition amongst young adult population. Lower extremity structural factors, such as increased femoral anteversion and lateral tibial torsion, may contribute to patellofemoral malalignment and anterior knee pain. The aim of this study was to evaluate the lower extremity structural factors and related patellofemoral alignment parameters that play a role in the aetiology of anterior knee pain.

Anthropometric measurements of tibial plateau and correlation with the current tibial implants.

Purpose: The aim of the study was to make an anthropometric analysis at the resected surfaces of the proximal tibia in the Turkish population and to compare the data with the dimensions of tibial components in current use. We hypothesized that tibial components currently available on the market do not fulfil the requirements of this population and a new tibial component design may be required, especially for female patients with small stature.

Methods: Anthropometric data from the proximal tibia of 226 knees in 226 Turkish subjects were measured using magnetic resonance imaging.

Methods: We retrospectively evaluated 11 male patients who presented at our emergency department (January 2011-March 2013) with multiple fingertip injuries and who were treated with a reverse-flow homodigital flap.

Culture-negative periprosthetic joint infection.

➤ Negative results on culture still pose a real challenge in the diagnosis of periprosthetic joint infection.➤ There are numerous reasons for the inability to isolate the infecting organism from the affected joint, the most important of which is the administration of antibiotics prior to obtaining culture samples.➤ For patients suspected of having a periprosthetic joint infection, antibiotics should not be given until the diagnosis is confirmed or aspiration of the joint should be delayed for at least two weeks after the last dose of antibiotics.

Nitric oxide inhibits autophagy via suppression of JNK in meniscal cells.

Objective: Autophagy is a potential protective mechanism that is involved in several degenerative diseases. Nitric oxide (NO) is associated with programmed cellular death in meniscal cells, but whether it can induce autophagy is still undetermined. This study aims to investigate the interaction between autophagy and NO in normal human meniscal cells.

Purpose: This study investigated the efficacy of platelet-rich plasma (PRP) on articular surfaces on which the mosaicplasty technique was performed. Our hypothesis was that PRP can accelerate the osseointegration process and enhance the quality of articular integrity after the mosaicplasty procedure.

Methods: Standard defects were created in the femoral groove of both patellofemoral joints of 12 New Zealand rabbits.

Primary hydatid disease of brachialis and biceps brachii muscles: a case report.

Primary hydatid cyst of the skeletal muscle is very rare and accounts for less than 1% of all cases. It is often asymptomatic and can pose diagnostic problems. Accurate diagnosis should be made using ultrasonography and magnetic resonance imaging.

Patients with black hip and black knee due to ochronotic arthropathy: case report and review of literature.

Ochronotic arthropathy is a manifestation of longstanding alkaptonuria. With increasing age, an accumulation of pigment deposits of homogentisic acid in the joint cartilage results in ochronotic osteoarthritis. We present a case of a 62-year-old female who underwent staged left uncemented total hip and right cemented total knee arthroplasty for osteoarthritis secondary to ochronosis.
