Conditions studied: Patellofemoral Dislocation, Tibial Tubercle Osteotomy, Medial Patellofemoral Ligament Reconstruction
In brief
The aim of this study is to investigate the role of tibial tubercle osteotomy (TTO) on the subjective and objective outcomes following medial patellofemoral ligament reconstruction (MPFL-R) in patients with an increased tibial tubercle-trochlear groove (TT-TG) distance with or without patella alta. This Pilot RCT will assess the feasibility of conducting this study for: 1. The ability to recruit study patients 2. Adherence to the study protocol 3. Completion rates of patient follow-up at a minimum of 12 months post-operative
