TTT Follow-up Study

Patellofemoral pain is a common complaint especially in young adults. It can be caused by patellar maltracking. Part of this is a patella alta. When patellar maltracking is the cause of the problem and conservative therapy fails, surgery, a tibial tuberosity transposition, may be considered. Most research has been done in patients with recurrent patella luxation. However, in patients without luxation, research is scarce.It is known that patients with patella alta have an increased risk of developing patellofemoral chondropathy due to increased pressure. With this study, we aim to investigate whether and how a tibial tuberosity transposition in patients with patella alta and no instability affects the degree of patellofemoral chondropathy and patient satisfaction after 10 years. This will allow us to educate patients regarding long-term outcomes better.
