摘要： Devices and methods provided for joint arthroscopy contemplate and enable the provision of patient specific instruments (PSI). The devices and anatomical features of a patient are rendered adjustable by the provision of guide elements and feature to account for and enable repositioning of the anatomical features during surgery. Where the joint arthroscopy involves ankle arthroplasty, a PSI system includes a tibial PSI operable to be coupled to a tibia and a talar PSI operable to be coupled to a talus. Pins pass through the tibial PSI into the tibia and through the talar PSI into the talus. The tibia and talus are aligned based on the tibial PSI, the talar PSI, the pins, and optionally a connection guide operable to receive, or be coupled to, the pins. The tibial PSI and the talar PSI allow for the transfer of pre-operative planning to intra-operative procedures.
