ClinConnect Summary

This clinical trial, called "SHould You transFer the Tubercle?", is studying the impact of a specific surgical procedure called tibial tubercle osteotomy (TTO) on patients who have had surgery to reconstruct a ligament in the knee, known as the medial patellofemoral ligament (MPFL). The goal is to see how TTO affects recovery and function in patients with a larger than normal distance between the tibial tubercle (a bony bump on the shin) and the groove in the thigh bone where the kneecap sits. The study is currently recruiting participants aged 13 to 30 years who have experienced repeated issues with kneecap dislocation and have certain measurements on their imaging tests.

Participants in the trial can expect to follow a specific study plan and provide feedback on their recovery for at least a year after their surgery. To join, individuals must meet certain criteria, including having a specific distance measurement related to their knee anatomy and being free from certain other knee conditions. This study is focused on understanding whether TTO is beneficial and how well it can be integrated into the recovery process for young people with this knee issue.
