Devices, kits, and methods that may be used to establish a distal femoral resection position or a proximal tibial resection position and a prosthetic gap in a total knee arthroplasty procedure are provided. Devices for establishing a distal femoral resection position or a proximal tibial resection position may comprise a support that attaches to and references a proximal resected tibia or distal resected femur and supports and establishes the position of a resection guide. A kit may comprise a device for establishing a distal femoral resection position or proximal tibial resection position and additional components that complement the device or facilitate application of the device during a total knee arthroplasty procedure. Methods for establishing a distal femoral resection position or a proximal tibial resection position are also provided.
