Local infiltration anesthesia with high dose ropivacaine and dexmedetomidine in major knee surgery is safe.

Background: The role of local infiltration anesthesia (LIA) in knee surgery is significant. LIA can be more potent than a nerve block, but without the downsides. A wide range of agents are used for LIA, including some off-label medications such as dexmedetomidine and ropivacaine.

No difference in surgical time and total theatre time between robotically assisted and computer assisted total knee arthroplasty.

Introduction: A number of studies have demonstrated a significant reduction of surgical time for robotically assisted surgery (RAS) total knee arthroplasty (TKA) after the learning curve between 6 and 43 cases. It is unknown if the logistics of RAS produce a longer total theatre time since published literature only reflects the surgical time. It is also unknown how RAS surgical and total theatre times compare with computer assisted surgery (CAS) TKA.

Orthogeriatric co-management in pelvic and acetabular fractures.

Background: Osteoporosis, age and frailty significantly impacts outcomes in fragility fractures of the pelvis, increasing morbidity and mortality. Identifying frailty aids in risk stratification and personalized care plans, enhancing recovery and reducing complications in older adults. Orthogeriatric co-management, an interdisciplinary approach combining orthopedics and geriatrics, optimizes care for older adults with fragility fractures.

The effect of different alignment strategies on trochlear orientation after total knee arthroplasty.

Purpose: When planning and delivering total knee arthroplasty (TKA), there are multiple coronal alignment strategies such as functional alignment (FA), kinematic alignment (KA), mechanical and adjusted mechanical alignment (MA, aMA). Recent three-dimensional and robotic-assisted surgery (RAS) studies have demonstrated that KA potentially better restores the trochlear anatomy than MA. The purpose of this study was to compare the restoration of the native trochlear orientation in patients undergoing RAS TKA using four different alignment strategies.
