Purpose: To assess the association between skeletal-muscle endurance performance and mitochondrial oxidative capacity of the hamstrings as respectively measured by biomechanical and physiological standards.
Methods: Nineteen (12 men and 7 women) healthy, young, recreationally active participants enrolled in our study. Participant characteristics comprised a mean and SD age of 21.

Objective: Anatomical reconstruction of the posterior cruciate ligament (PCL) with suture tape augmentation to enhance primary stability.
Indications: Acute or chronic PCL ruptures, either isolated or as part of multiligamentous injuries, in cases of symptomatic instability or failure of conservative treatment.
Contraindications: Fixed posterior drawer, active infection, bony avulsion.

Hamstring strain injuries frequently occur during the late swing phase of running; however, the breaking strength of the human hamstring muscle-tendon complexes remains unclear. This study aimed to determine the breaking strength of human hamstring muscle-tendon complexes. To this end, seven cadaveric specimens preserved using the Thiel's method were examined.

Introduction: Tunnel widening following anterior cruciate ligament (ACL) reconstruction remains a significant clinical concern. Polyether ether ketone (PEEK) screws offer favorable biomechanical properties and MRI compatibility; however, they lack osteoconductivity, which may contribute to tunnel widening. This study investigated whether hydroxyapatite (HA)-coated polyether ether ketone (PEEK) screws reduce tibial tunnel widening compared to uncoated PEEK screws, considering the osteoconductive properties of HA.

Background: Medial patellofemoral ligament (MPFL) reconstruction is the main procedure performed for recurrent patellar instability. Choosing wisely between graft options is particularly important in this specific population, who often lacks neuromuscular control. The gracilis, semitendinosus, and quadriceps tendons are the most frequently used autografts, but harvesting can lead to reduced thigh muscle strength and poorer balance control.
