Functional alignment in robotic-assisted total knee arthroplasty for valgus deformity achieves safe coronal alignment and excellent short-term outcomes.

Purpose: Functional alignment (FA) in total knee arthroplasty (TKA) prioritizes soft tissue balancing and anatomical restoration without systematic correction to neutral alignment. Most studies have focused on varus deformity, with little evidence available about FA in valgus deformity. The hypothesis of the present study was that FA in robotic-assisted TKA for valgus deformity would demonstrate correction of the coronal alignment and yield satisfactory short-term outcomes.

Eccentricity and greater size of the glenosphere increase impingement-free range of motion in glenoid lateralized reverse shoulder arthroplasty: A computational study.

Introduction: Increasing the impingement-free Range Of Movement (ROM) is crucial for improving patient's functional outcome and reducing the rate of scapular notching. The purpose of this study was to compare, in a virtual model of Reverse Shoulder Arthroplasty with glenoid lateralization (L-RSA): 1) the impingement-free range of movement (ROM) between 155° Grammont-style inlay stem and 135° flushlay stem; 2) the effect of glenosphere size and type (centered vs eccentric) on impingement-free range of movement (ROM) using a 135° Neck Shaft Angle (NSA) flushlay stem.

Materials And Methods: 200 CT-scans of patients undergoing shoulder replacement for Cuff tear Arthropathy were analyzed in the present study.

Femoral cartilage thickness measured on MRI varies among individuals: Time to deepen one of the principles of kinematic alignment in total knee arthroplasty. A systematic review.

Purpose: Kinematically aligned total knee arthroplasty (KA TKA), as a pure resurfacing procedure, is based on matching implant thickness with bone cut and kerf thickness, plus cartilage wear. However, the assumption of a consistent 2 mm femoral cartilage thickness remains unproven. This study aimed to systematically review the available literature concerning magnetic resonance imaging (MRI) assessment of femoral cartilage thickness in non-arthritic patients.

Osteonecrosis as a manifestation of Long-COVID Syndrome: a systematic review.

Purpose SARS-CoV-2 is an RNA virus responsible for COVID-19 pandemic. Some authors described the set of persistent symptoms COVID-related as "Long-COVID Syndrome." Several cases of post-COVID-19 osteonecrosis (ON) are described.

Mechanically aligned total knee arthroplasty does not yield uniform outcomes across all coronal plane alignment of the knee (CPAK) phenotypes.

Purpose: Patient dissatisfaction rates following total knee arthroplasty (TKA) reported in the literature reach 20%. The optimal coronal alignment is still under debate. The aim of this retrospective study was to compare clinical outcomes in different coronal plane alignment of the knee (CPAK) phenotypes undergoing mechanically aligned (MA) TKA.
