Purpose To determine whether patient‐specific instrumentation (PSI), computer‐assisted
surgery (CAS) or robot‐assisted surgery (RAS) enable more accurate rotational alignment of …

Aim of the study To identify the most reliable anatomical landmarks and imaging techniques
for assessing the rotation of the tibial component in total knee arthroplasty (TKA). Methods …

Introduction The most commonly used tool for implant positioning are conventional
instruments (CI) followed by computer-assisted surgery (CAS). A number of studies have …

Introduction Tibial component design and positioning contribute more to patient satisfaction
than previously realized. A surgeon needs to decide on the size and rotation, bearing in …

Purpose To describe a technique for flexion gap management in total knee arthroplasty
(TKA) using conventional instrumentation with minimal soft tissue release, by aligning the …

Introduction Although the most commonly used method of femoral component alignment in
total knee arthroplasty (TKA) is intramedullary (IM) guides, this method demonstrated a …

Background We evaluated the effectiveness of our new technique “Range of motion-
anatomical (ROM-A) technique” which is the combination of the self-positioning technique …

Purpose The tibial anatomical anteroposterior (AP) axis “Akagi's line” was originally defined
on computed tomography (CT) in total knee arthroplasty (TKA); however, its intraoperative …

Purpose Unstable distal radius intra-articular fractures require restoration of alignment.
Exact fixation of intra-articular fragments is ideal. Here, we employed intraoperative …

Background To investigate in vivo kinematics of total knee arthroplasty (TKA) with the
introduction of a mildly constrained (MC) type of polyethylene (PE). We compared the knee …
