Effects of the medial and lateral tibial slope on knee joint kinematics in total knee arthroplasty

Current Directions in Biomedical Engineering, 2018
Implant design in total knee arthroplasty is a key factor for the recovery of function and mobility of the joint. However, there is a lack of knowledge on the complex relationship between design features and the biomechanical situation.

Biplane opening wedge high tibial osteotomy with a distal tuberosity osteotomy, radiological and clinical analysis with minimum follow-up of 2 years

Journal of Experimental Orthopaedics, 2019
Background High tibial osteotomy is an established and helpful treatment for unicompatimental osteoarthritis associated with varus deformity. However, asupratubercle high tibial osteotomy leads to a decrease in patellar height making the technique not ...

Comparison of Different Techniques for Measuring Posterior Tibial Slope [PDF]

Orthop J Sports Med
Objectives: The posterior tibial slope assessment is crucial in preoperative planning for various surgeries. Different measurement methods exist, but no study has compared them. This study aims to verify the equivalence of four techniques for measuring the posterior tibial slope in lateral knee radiographs and assess inter-observer reliability among ...

Identification of a Force‐Induced Sox9+Acan+ Transitional Subpopulation Linked to FGF2–FGFR2–ERK Signaling in Orthodontic Bone Remodeling

Advanced Science, EarlyView.
Mechanical loading induces a previously unrecognized Sox9+Acan+ transitional mesenchymal cell population in the periodontal ligament that promotes osteoclastogenesis via the FGF2–FGFR2–ERK axis. Targeting this mechanoresponsive stromal population using a localized GelMA@siRNA delivery strategy attenuates pathological osteoclast overactivation and root ...

Quantifying the Tibiofemoral Joint Space Using X-ray Tomosynthesis [PDF]

, 2011
Purpose: Digital x-ray tomosynthesis (DTS) has the potential to provide 3D information about the knee joint in a load-bearing posture, which may improve diagnosis and monitoring of knee osteoarthritis compared with projection radiography, the current ...

Patient-specific instrumentation does not improve radiographic alignment or clinical outcomes after total knee arthroplasty: A meta-analysis [PDF]

, 2016
Background and purpose: Patient-specific instrumentation (PSI) for total knee arthroplasty (TKA) has been introduced to improve alignment and reduce outliers, increase efficiency, and reduce operation time.

Resilient Calvarial Bone Marrow Supports Retinal Repair in Type 2 Diabetes

Advanced Science, EarlyView.
Skull bone (calvarium) marrow in diabetic mice stay structurally intact and keeps making blood cells, unlike the bone marrow of the leg bones. The skull marrow is exposed to cerebrospinal fluid (CSF), which contains protective molecules called oxysterols.

Proximal tibial morphology and risk of posterior tibial cortex impingement in patients with AA-sized Oxford unicompartmental knee arthroplasty tibial implants

Journal of Orthopaedic Surgery and Research, 2020
Background In cases of Oxford unicompartmental knee arthroplasty (UKA), an increase in anteroposterior and medial-lateral length is usually disproportional when comparing AA and A-sized tibial components.
