The document discusses potential future directions for rotator cuff repair surgery. It describes 4 possibilities - 1) biological repairs that enhance healing using growth factors, 2) augmentation devices to reinforce repairs, 3) gene therapy and nano-surgery approaches for prevention and treatment, and 4) algorithms to better determine who needs surgery versus non-operative treatment based on age, genetics, and other factors. The future may include enhanced sutures that promote angiogenesis, balloon devices to support tissue, gene therapies administered through self-monitoring techniques, and remotely-controlled nano-instruments.
