1. A method for performing hip arthroplasty, comprising:
- attaching a first orthopedic system to a bone of the patient, the first orthopedic system comprising a reference post and a probe;
sliding a portable surgical orientation device and the probe relative to the reference post until the probe contacts an anatomical landmark;
measuring at least one of orientation or position of the portable surgical orientation device when the probe contacts the anatomical landmark;
measuring an orientation of an anatomical plane on the patient'"'"'s hip using a second orthopedic system and the portable surgical orientation device;
orienting an implant relative to the anatomical plane using the second orthopedic system; and
measuring changes in at least one of leg length and joint offset using the portable surgical orientation device.
