Osseointegration, or bone implantation is the next step in prosthetic technology. It allows transfemoral amputees to not require the use of a socket with their prosthesis. In 2020 the Osseoanchored Prostheses for the Rehabilitation of Amputees (OPRA) Implant System was approved in the United States by the Food and Drug Administration. If a previous transfemoral socket user that has passed the contraindication and indication standards switches to osseointegration, their quality of life and proprioception would increase, and their skin breakdown would decrease.

The study aims to measure the benefits through qualitative conversation and interviews with the patients, qualitative before and after videos, osseoperception measurements through the footplate, and through functional ability measurements of hip range of motion, TUG tests, and AMPPro testing.

This will be a long term study of three years in which the patient will meet with the team of prosthetists, doctors, physical therapists, and researchers more frequently at the start of the osseointegration process. The interviews and measurements will become less frequent over time, happening every 6 months.
