An Acute Oblique Osteotomy and Suture Ligation Procedure to Shorten the Fibula in Lateral Closing-Wedge High Tibial Osteotomy

open access: yesArthroscopy Techniques, 2020
The purpose of this description is to report an “acute oblique osteotomy and ligation” (AOOL) procedure to shorten the fibula in high tibial osteotomy (HTO). A 4-cm longitudinal skin incision is made at the lateral aspect of the leg.

Viridicatol from the Deep‐Sea‐Derived Fungus Alleviates Bone Loss by Targeting the Wnt/SHN3 Pathway

open access: yesAdvanced Science, EarlyView.
Viridicatol (VDC), isolated from the deep‐sea‐derived fungus, enhances osteogenesis in vitro and in vivo by targeting Wnt/SHN3 signaling pathway. It can be delivered via engineered nanovesicles to mitigate bone loss of osteoporosis, fracture repair, and osteogenesis imperfecta.

Contrast‐enhanced micro‐computed tomography of compartment and time‐dependent changes in femoral cartilage and subchondral plate in a murine model of osteoarthritis

open access: yesThe Anatomical Record, Volume 306, Issue 1, Page 92-109, January 2023., 2023
Abstract A lack of understanding of the mechanisms underlying osteoarthritis (OA) progression limits the development of effective long‐term treatments. Quantitatively tracking spatiotemporal patterns of cartilage and bone degeneration is critical for assessment of more appropriately targeted OA therapies.

Biological Reinforced Concrete for Cartilage Repair With 3D Printing

open access: yesAdvanced Science, EarlyView.
Inspired by concrete rebar structures in engineering, the concept of biological reinforced concrete uses 3D‐printed ultrafine fiber networks (UFNs) as biodegradable “biorebars”, hybrid biohydrogels as “biocement”, and stem cells as “bioactive aggregates” to fabricate biomimetic cartilage.

Patellar Tendon Reconstruction for a Chronic Extensor Mechanism Deficit Using an Achilles Tendon Allograft With Hamstring Autograft and Suture Augmentation

open access: yesArthroscopy Techniques, 2020
Patellar tendon ruptures are the third most common injury to the extensor mechanism. These injuries are debilitating to the patient, and delays in treatment can present a challenge to the treating surgeon.

An Example of Microwave Diagnosis for Knee Osteophyte by 3D Parallel FD-FDTD Approach [PDF]

open access: yesarXiv
A parallel 3-D Frequency Dependent Finite Difference Time Domain (FD-FDTD) method was implemented based on the Single Program Multiple Data (SPMD) technique to analyze the feasibility of microwave diagnosis for the human knees. The parallel algorithm efficiently accelerates the FDTD computation for a large 3-D numerical knee model derived from a real ...

Hypothalamus Regulates Anabolic Metabolism of Articular Cartilage Superficial Chondrocytes through PGE2 Skeletal Interoception

open access: yesAdvanced Science, EarlyView.
Hypothalamus sympathetic norepinephrine inhibits regeneration of articular cartilage. Mechanical loading on bone during animal activity elevates PGE2 skeletal interoception to promote an anabolic renewal of the superficial membrane by downregulation of norepinephrine for articular cartilage proper thickness and integrity.

Tibial Tuberosity Transfer in Combination With Medial Patellofemoral Ligament Reconstruction: Surgical Technique

open access: yesArthroscopy Techniques, 2017
The stability of the patellofemoral joint relies on the tenuous interplay of soft tissue and bony factors. Anatomic risk factors for instability include a shallow trochlea, an abnormally lateral tibial tubercle position, patella alta, hypermobility, or a
