SHould You TransFer the Tubercle?

Medial Patellofemoral Ligament Reconstruction | Patellofemoral Dislocation | Tibial Tubercle Osteotomy

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
