Abstract: In this paper we present a method for automatically computing the angles between bones and implants after a knee replacement surgery (Total Knee Arthroplasty, TKA), along with the world’s first public dataset of TKA radiographs, complete with ground truth angle annotations. We use the Radon transform to determine the angles of the relevant bones and implants, and obtain 94.9% measurements within 2º. This beats the current state-of-the-art by 2.9%. The system is thus ready to be used in assisting surgeons and replacing time consuming and observer dependent manual measurements.
