Non-Anatomic Reconstruction in Multiligament Knee Injuries: A Functional Approach.

: Multiligament knee injuries, involving damage to multiple stabilizing structures, present a significant challenge in orthopedic surgery, often resulting in knee instability and compromised function. While anatomic ligament reconstruction has been traditionally advocated, non-anatomic techniques may provide effective alternatives, particularly for patients with moderate functional demands who do not require high-level athletic performance. : In this study, we assessed the outcomes of a non-anatomic, hybrid surgical approach involving combined arthroscopic and open non-anatomic ligament reconstruction in 60 patients with multiligament knee injuries.

A Custom-Made Electronic Dynamometer for Evaluation of Peak Ankle Torque after COVID-19.

The negative effects of SARS-CoV-2 infection on the musculoskeletal system include symptoms of fatigue and sarcopenia. The aim of this study is to assess the impact of COVID-19 on foot muscle strength and evaluate the reproducibility of peak ankle torque measurements in time by using a custom-made electronic dynamometer. In this observational cohort study, we compare two groups of four participants, one exposed to COVID-19 throughout measurements and one unexposed.

A Custom-Made Lower Limb Dynamometer for Assessing Ankle Joint Torque in Humans: Calibration and Measurement Procedures.

Custom-made dynamometry was shown to objectively analyze human muscle strength around the ankle joint with accuracy, easy portability and low costs. This paper describes the full method of calibration and measurement setup and the measurement procedure when capturing ankle torque for establishing reliability of a portable custom-built electronic dynamometer. After considering the load cell offset voltage, the pivotal position was determined, and calibration with loads followed.

Surgical treatment in a case of giant macrodystrophia lipomatosa of the forefoot.

Macrodystrophia lipomatosa is a rare, congenital, non-hereditary disease, characterized by local gigantism of the fingers or toes. We report the case of a 37-month-old boy, with no prior past medical history, who presented with a gigantic dystrophy of the left forefoot. The location of the deformity was involving the plantar and dorsal aspect of the foot, and digits 1 to 4.

Morphological and functional characterization of femoral head drilling-derived mesenchymal stem cells.

Adult mesenchymal stem cells (MSCs) were primary identified as bone marrow-derived cells, fibroblast-like morphology, and adherent to plastic surfaces of in vitro culture plate. Their identification criteria evolved in time to a well-established panel of markers (expression of CD73, CD90, and CD105) and functional characteristics (adipogenic, osteogenic, and chondrogenic trilineage differentiation ability), which can be applied to adult mesenchymal stem cells obtained from other tissue sources. We tried to assess the potential stemness of femoral head drilling-derived cells as a new source of mesenchymal stem cells (FH-MSCs).
