Mechanisms underlying microglial colonization of developing neural retina in zebrafish

eLife, 2021
Microglia are brain-resident macrophages that function as the first line of defense in brain. Embryonic microglial precursors originate in peripheral mesoderm and migrate into the brain during development.

Does lucency equate to revision? A five‐year retrospective review of Attune and Triathlon total knee arthroplasty

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 31, Issue 11, Page 4773-4781, November 2023., 2023
Abstract Purpose The Attune® total knee arthroplasty system was introduced in 2013 to address lingering issues of patient dissatisfaction. However, recent literature reports concerns of early tibial tray debonding. The aim of this study was to compare the incidence of radiolucent lines, survivorship and patient reported outcome‐measures between the ...

Effectiveness and Accuracy of a Patient‐Specific Instrumentation System for Total Hip Arthroplasty

Orthopaedic Surgery, Volume 15, Issue 3, Page 878-887, March 2023., 2023
(A) Self‐designed THA PSI system. (B) Simulated THA using PSI system in model bone. Objective Traditional total hip arthroplasty (THA) is often performed by visual inspection due to the lack of reliable reference, which results in inappropriate position of prosthesis and poor outcomes.

Extended Fixation for Paprosky Type III Acetabular Defects in Revision Total Hip Arthroplasty with a Minimum Follow‐Up of 2 Years

Orthopaedic Surgery, Volume 15, Issue 1, Page 205-213, January 2023., 2023
We proposed the concept of “iliac extended fixation,” and found that EIEF (extracavitary iliac extended fixation) and IIEF (intracavitary iliac extended fixation) with porous metal augments and cementless cups are effective in reconstructing severe superior acetabular bone defects, with promising short‐term clinical and radiographic outcome.

The Chitranjan S. Ranawat Award [PDF]

Clinical Orthopaedics & Related Research, 2017
Neutral mechanical alignment (MA) in total knee arthroplasty (TKA) aims to position femoral and tibial components perpendicular to the mechanical axis of the limb. In contrast, kinematic alignment (KA) attempts to match implant position to the prearthritic anatomy of the individual patient with the aim of improving functional outcome.

Diagnosis and Prevalence (1975–2010) of Sudden Death due to Atlantoaxial Subluxation in Cervical Rheumatoid Arthritis: A Literature Review

The Scientific World Journal, Volume 2023, Issue 1, 2023., 2023
Rheumatoid arthritis (RA), a chronic inflammatory disease primarily affecting synovial joints and tendons, can potentially impact various organs within the body. One notable complication associated with RA is upper cervical spine instability, medically termed atlantoaxial subluxation (AAS).

Implication of Changes in the Imaging Measurements after Mechanically Aligned Total Knee Arthroplasty

Orthopaedic Surgery, Volume 14, Issue 12, Page 3322-3329, December 2022., 2022
The tibia is simplified as a two‐dimensional graph, The lower extremities were in an unnatural state within one year after TKA. The changes of the lower extremities force line were actually the common results of the gradual adaptation of the lower extremities to TKA and the lateral swing of the extremities 3° after surgery.

Comparison of Tibial Tubercle Landmark Technique and Range of Motion Technique in Primary Total Knee Arthroplasty: A Retrospective Cohort Study

Orthopaedic Surgery, Volume 14, Issue 12, Page 3159-3170, December 2022., 2022
Postoperative CT scans shows component axis and three reference lines. Objective There is not a standard for rotational alignment of the tibial component in total knee arthroplasty (TKA). For now, the most commonly methods are tibial‐tubercle ‐landmark technique (TTL) and range‐of‐motion technique (ROM).
