TL;DR: An applicable and evidence-based, step by step, decision pathway for the diagnosis and treatment of acute ankle injuries is presented, which can be implemented in any emergency department or doctor's practice and provides quality assurance for the patient and promotes confidence in the attending physician.

TL;DR: The data support the hypothesis that if low-oxygen atmospheres are expected at the site of implantation, hypoxic pretreatment may be beneficial for the cells' subsequent in vivo performance and suggest that low oxygen concentrations may preserve the stemness of hMSCs.

TL;DR: The rehabilitation protocol after Achilles tendon repair should allow immediate full weight bearing and patients showed significantly higher satisfaction, less use of rehabilitation resources, earlier return to pre-injury activities and further demonstrated significantly increased calf muscle strength, reduced atrophy and tendon elongation.

TL;DR: Acute fractures to the proximal fifth metatarsal bone should be classified into two entities only: metaphyseal fractures not extending beyond the distal end of the fourth-fifth intermetatarsal articulation, as these fractures, regardless of the number of fragments, displacement and intraarticular involvement, should be treated functionally.

TL;DR: Hypoxia promoted a more homogeneous cell population with a significantly higher fraction of rapidly self-renewing cells which are believed to be the true stem cells, and altered their integrin expression.
