EXTERNAL DISLOCATION OF THE KNEE [PDF]

Journal of the American Medical Association, 1911
Dislocation at the tibiofemoral joint is rare, constituting about 1 per cent. of all cases. External dislocation occurs in 5 per cent. of these injuries in this location. It is rare in its complete form. When complete the dislocation is usually compound. The following case was incomplete: Dec. 30, 1910: Mr. H. L.

Proximal tibiofibular joint dislocation is rare in knee dislocations type Schenck III or higher

Journal of Experimental Orthopaedics
Purpose The purpose of the study was to determine the prevalence of proximal tibiofibular joint (PTFJ) dislocations in knee dislocations classified as Schenck type ≥III and to compare with uninjured contralateral knees, which served as control cohort ...

Adult Congenital Permanent Bilateral Dislocation of the Patella with Full Knee Function: Case Report and Literature Review

Case Reports in Medicine, 2012
Congenital permanent dislocation of the patella is a rare disorder of the knee joint in which the patella is permanently displaced, even in extension and is fixed on the lateral aspect of the femoral condyle.

Wavelength‐ and Helicity‐Reconfigurable Circularly Polarized Optical Diodes Enabled by Molecular Photoswitches

Advanced Materials, EarlyView.
All‐optical, photoswitchable diode‐type device for tunable nonreciprocal (asymmetric) transmission of CPL across a broad spectrum of light is demonstrated using molecular motor (photoswitch)‐doped cholesteric liquid crystals (CLCs) sandwiched between polyvinyl alcohol (PVA) and polydopamine (PDA)‐PVA composite layers.

Total joint replacement for neglected posterior knee dislocation following septic arthritis after arthroscopy

Acta Orthopaedica et Traumatologica Turcica, 2017
This report presents the first case of a knee dislocation following septic arthritis after arthroscopy. A 65-year-old woman had an arthroscopy with irrigation and debridement (I&D) of the joint and microfracture for the chondral lesions.

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion

Advanced Robotics Research, EarlyView.
A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

Combating Inflammation and Promoting Anabolism in Osteoarthritic Cartilage Defect With an MMP13‐Sensing Dual‐Drug Scaffold

Advanced Science, EarlyView.
ABSTRACT Osteoarthritis (OA) is a widespread degenerative joint condition marked by progressive cartilage breakdown, and a chronic inflammatory microenvironment, where conventional therapies largely fail to halt disease progression. To address this unmet need, an intra‐articularly implantable, disease‐responsive scaffold was developed for combinatorial
