Acquired changes in thickness and length of patellar tendon after primary total knee arthroplasty: a prospective ultrasonographic study with over 4 years of follow-up.

Previous literature has reported changes in the length or thickness of the patellar tendon (PT) following primary total knee arthroplasty (TKA). This study aims to determine the structural changes in both the length and thickness of the PT after primary TKA using ultrasound (US) and to investigate the association between these changes and clinical outcomes after a minimum follow-up of 48 months. This prospective study used the US on 60 knees of 32 patients (aged 54-80, mean 64.

Efficacy of arterial occlusion pressure estimation-based tourniquet pressure settings in upper limb surgery.

Background: The use of a minimal individualized effective pneumatic tourniquet pressure is recommended to avoid pressure related complications in extremity surgery. The aim of this study was to investigate the efficacy of arterial occlusion pressure estimation-based tourniquet pressure settings in upper limb surgery.

Methods: Hundred and fifteen patients undergoing upper limb surgeries were enrolled in the present study.

Reliability of Real-Time Sonoelastography in the Diagnosis of Supraspinatus Tendinopathy.

The practicality of real-time sonoelastography in the diagnosis of tendinopathy is being discussed since the beginning of its use in musculoskeletal system. The aims of this study were to compare the elasticity of pathologic supraspinatus tendon with the uninvolved side by sonoelastography and to determine the relationship between the sonoelastographic findings and magnetic resonance imaging (MRI) grade of the tendinosis. Eighty-2 patients (50 males, 32 females, mean ± SD age = 53.

Tourniquet pressure settings based on limb occlusion pressure determination or arterial occlusion pressure estimation in total knee arthroplasty? A prospective, randomized, double blind trial.

Objective: The aim of this study was to compare the limb occlusion pressure (LOP) determination and arterial occlusion pressure (AOP) estimation methods for tourniquet pressure setting in adult patients undergoing knee arthroplasty under combined spinal-epidural anesthesia.

Methods: Ninety-three patients were randomized into two groups. Pneumatic tourniquet inflation pressures were adjusted based either on LOP determination or AOP estimation in Group 1 (46 patients, 38 female and 8 male; mean age: 67.

Obese patients require higher, but not high pneumatic tourniquet inflation pressures using a novel technique during total knee arthroplasty.

Objectives: This study aims to investigate the effect of obesity on pneumatic tourniquet inflation pressures determined with a novel formula during total knee arthroplasty (TKA).

Patients And Methods: Data of 208 patients (19 males, 199 females; mean age 69.8 years; range, 53 to 84 years) who were performed TKA between January 2013 and December 2016 were evaluated prospectively.
