Background: Few published articles exist reporting the long-term evaluation of the Roux-Elmslie-Trillat procedure.
Purpose: To assess the long-term effect of the Roux-Elmslie-Trillat procedure in preventing recurrent subluxation and dislocation of the patella.
Study Design: Case series; Level of evidence, 4.
Methods: Eighteen patients who underwent the Roux-Elmslie-Trillat procedure for dislocation or subluxation of the patella were identified from a group previously evaluated at a mean follow-up of 3 years. The prevalence of recurrent subluxation or dislocation at a mean follow-up of 26 years was compared with the prevalence reported at the mean follow-up of 3 years. Although not the focus of this study, Cox functional scores were obtained from the smaller group and compared with the results at the 3-year follow-up.
Results: Seven percent (95% confidence interval, 0.000.32) of the patients had recurrent subluxation at 26 years compared with 7% (95% confidence interval, 0.030.13) of the study population reported at 3 years (P = 1.00). Fifty-four percent (95% confidence interval, 0.270.79) rated their affected knee as good or excellent at 26 years compared with 73% (95% confidence interval, 0.640.81) of the larger study population reported at 3 years (P = .14).
Conclusion: The prevalence of recurrent subluxation and dislocation in patients with patellofemoral malalignment who underwent the Roux-Elmslie-Trillat procedure for dislocation or subluxation of the patella is similar at 3 and 26 years after the procedure. The long-term functional status of the affected knee in patients who underwent the Roux-Elmslie-Trillat procedure declined.
