Purpose: To investigate tibiofemoral knee kinematics when shifting the femoral insertion point of the modified Lemaire lateral extra-articular tenodesis (LET) anterior to the lateral epicondyle.
Methods: Six fresh-frozen human knee joints were tested on a test bench in the following states: (1) native, (2) anterolateral insufficient, (3) original Lemaire (oLET; insertion point: 4 mm posterior and 8 mm proximal to the epicondyle), (4) anterior Lemaire (aLET; insertion point: 5 mm anterior and 5 mm proximal to the epicondyle). Internal tibial rotation was statically investigated under an internal tibial torque of 5 Nm in 0°, 30°, 60°, and 90° of flexion.
Movement-based cognitive training does not significantly shorten the learning curve for acquiring arthroscopic basic skills.

Purpose: Skilful arthroscopy requires an aboveaverage level of manual dexterity. It is evident that particular motor skills can be learned and trained before arthroscopic training. The aim of this prospective cohort study was to investigate the impact of movement-related cognitive training on the learning curve during arthroscopic basic training.

- This study examines the biomechanical properties of three all-suture anchors used for biceps tenodesis, specifically looking at their load-to-failure characteristics and optimal insertion angles in porcine humeri models.
- The findings indicate that the 2.6 FiberTak® anchor had the highest load-to-failure at a 90° angle compared to the 1.9 and 1.6 FiberTak® anchors, with significant differences observed across insertion angles.
- Overall, while all anchors proved effective, the study suggests that using a 90° insertion angle maximizes fixation strength, and the 2.6 FiberTak® is particularly promising due to its unique failure mode.
This study aimed to compare the validity of a local positioning system (LPS) during outdoor and indoor conditions for team sports. The impact of different filtering techniques was also investigated. Five male team sport athletes (age: 27 ± 2 years; maximum oxygen uptake: 48.

Hypoxia does further increase prefrontal cortex activity which provokes a reduced capability of efficient resource utilisation. This, again, might evoke that the capacity of the limited mental resources of a dual task will be reached at an earlier stage of task complexity.
