1. A surgical method for total ankle replacement (TAR), comprising:
obtaining a TAR implant, wherein the TAR implant comprises:
a tibial component comprising a tibial engagement surface and at least one bone engagement projection;
a talar component with a talar engagement surface and a talar articulation surface; and
a tibial insert configured to removably couple with the tibial component and comprising tibial articulation surface that articulates with the talar articulation surface;
conducting pre-operative templating;
making an incision to expose an ankle joint with a first tibia bone and a second talar bone;
continuing the incision while releasing soft tissue, comprising:
identifying the superficial peroneal nerve and retracting it laterally;
continuing incision to the extensor retinaculum;
identifying the extensor hallucis longus (EHL) tendon below the retinaculum;
dividing the retinaculum longitudinally over the EHL tendon;
leaving the sheath of the tibialis anterior (TA) tendon intact;
identifying the neurovascular bundle and retracting it laterally with the EHL tendon;
retracting the TA tendon medially; and
continuing incision until the anterior capsule is visualized;
aligning a joint alignment guide with the first tibia bone;
preparing the first tibia and second talar bones for receiving the TAR implant, comprising:
performing an anterior capsulotomy; and
removing osteophytes on the tibia and the talus;
coupling a tibial sizing block with a tibial alignment base;
performing a resection of the first tibia bone to form a resected tibia;
performing a resection to the second talar bone to form a resected talus;
trialing the TAR implant with the resected tibia and the resected talus via a TAR trial and guide system to determine sizes for the tibial component, the talar component and the tibial insert; and
closing the incision.
