Overview
The goal of this randomised controlled trial is to compare a tuberositas transposition (TTT) surgery with a home exercise program (HEP) in patients with patellofemoral pain syndrome (PFPS). The study aims to evaluate the efficiency of TTT in conjunction with a HEP compared to a HEP alone in patients with chronic PFPS.
Participants will randomly be allocated to the surgery or HEP group. Researchers will compare the surgery and HEP groups to see if activity-related pain and patient reported outcome measures (PROMs) are different.
