Perform total hip

replacement using

innovative augmented

reality-guided technology

Augmented reality is a new navigation that allows the
superposition of clinical information in the sight of the
surgeon. [1]

A team of orthopedic surgeons at New England Baptist
Hospital (NEBH) performed the first-ever augmented Impact of total joint

Total Knee Arthroplasty (TKA) also has positive effect
on patients with low mental health scores. [3]
