Evaluation of the permeation kinetics of formamide in porcine articular cartilage.

Cryopreservation of articular cartilage will increase tissue availability for osteochondral allografting and improve clinical outcomes. However, successful cryopreservation of articular cartilage requires the precise determination of cryoprotectant permeation kinetics to develop effective vitrification protocols. To date, permeation kinetics of the cryoprotectant formamide in articular cartilage have not been sufficiently explored.

Recovery and Return to Activity 1 Year After Ankle Fracture Managed With Open Reduction and Internal Fixation: A Prospective Longitudinal Cohort Study.

Background: Ankle fractures are common and frequently managed with open reduction and internal fixation (ORIF). Although these fractures can occur at any age, they are most common in younger individuals with high-energy trauma or older adults with lower-energy trauma. Our investigation focused on those aged 65 years or younger.

Factors associated with maintaining reduction following locking plate fixation of proximal humerus fractures: a population-based retrospective cohort study.

Background: Loss of reduction (LoR) can occur after locking plate fixation of proximal humerus fractures (PHFs). This study determined biomechanical features of fracture fixation associated with preventing LoR postoperatively. One-year reoperation rates were also compared between those with/without LoR.
