The burden of chronic musculoskeletal disorders is challenging and prompts therapeutic advancements. The notion that chronic conditions such as osteoarthritis and tendinopathy are linked to deficient healing by failure of one or several of the cellular/molecular processes involved is gaining ground. Alterations underpinning disruption of healing mechanisms that contribute to the development of chronic musculoskeletal pathologies include unresolved inflammation, abnormal angiogenic status, alterations in paracrine communication, decline in stem cell functioning and inability to maintain homeostasis in the extracellular matrix compartment. The complexity of failed healing may be challenged with interventions that target multiple biological processes such as cell therapies and/or platelet-rich plasma.
