Long-term outcome of total knee arthroplasty in patients with morbid obesity.

Introduction: Patients with morbid obesity and advanced painful knee osteoarthritis are considered as poor candidates for total knee replacement. Our aims were to evaluate the outcomes of TKR surgery and the risks for post-operative complications in patients with morbid obesity (BMI > 40 kg/m) as compared with obese patients (30 < BMI ≤ 40 kg/m) and non-obese patients, BMI < 30 kg/m); to evaluate if there are differences between morbid-obese patients (BMI 40-49.99 kg/m) and extreme morbid obese patients (BMI > 50 kg/m); and to present some surgical tips which can improve the TKR outcomes in morbid obese patients.

Ultrasonographic findings in a large series of patients with knee pain.

Background: Musculoskeletal ultrasound (MSKUS) is becoming more and more popular in the evaluation of different musculoskeletal abnormalities. The aim of this retrospective study was to document the prevalence and spectrum of MSKUS findings at the painful knee.

Materials And Methods: All the studies of MSKUS that were performed for the evaluation of knee pain during the previous 2 years at the Department of Radiology in Nazareth hospital were reviewed.

Simultaneous bilateral knee injection of methylprednisolone acetate and the hypothalamic-pituitary adrenal axis: a single-blind case-control study.

Objective: The objective of this study was to evaluate the effect of simultaneous bilateral intra-articular injection (IAI) of methylprednisolone acetate (MPA) on the hypothalamic-pituitary-adrenal axis in patients with knee osteoarthritis.

Methods: Nonselected patients with symptomatic bilateral knee osteoarthritis had simultaneous IAI of 80 mg MPA at each knee (group 1). Just before the injection and on weeks 1, 2, 4, 6, and 8 after it, patients had 1 µg adrenocorticotropin hormone stimulation test.

[A retrospective statistical analysis of the epidemiology of the congenital lumbar stenosis among the Jewish and Arab populations in Israel].

Congenital spinal lumbar stenosis is defined according to the midsagittal diameter of the lumbar spine. We conducted a retrospective statistical analysis of the results of 998 computer tomography studies of the lumbar spine as they were interpreted by the same author (E.N.
