Evaluation of the Roux-Elmslie-Trillat procedure for knee extensor realignment
The American Journal of Sports Medicine
|September 1, 1982
Summary
This study evaluated a surgical technique for patellofemoral malalignment, finding it satisfactory for preventing recurrent patellar subluxations in 93% of cases. However, only 66% of patients achieved good or excellent outcomes, influenced by associated knee pathologies.
Area of Science:
- Orthopaedic Surgery
- Biomechanics
- Sports Medicine
Background:
- Patellofemoral malalignment, including dislocations and subluxations, requires effective surgical correction.
- The Roux-Elmslie-Trillat procedure is a recognized surgical technique for addressing these conditions.
Purpose of the Study:
- To evaluate the efficacy and outcomes of the modified Roux-Elmslie-Trillat procedure for patellofemoral malalignment.
- To identify factors influencing the success of this surgical intervention.
Main Methods:
- Evaluation of 116 patients who underwent the modified surgical procedure.
- Minimum one-year follow-up with examination by an orthopaedic surgeon.
- Analysis of recurrence rates and subjective outcome ratings (good/excellent).
Main Results:
- The procedure demonstrated a satisfactory prevention of recurrent patellar subluxation, with only a 7% recurrence rate.
- Overall, 66% of procedures were rated as good or excellent.
- Success rates were significantly impacted by the presence of intraarticular pathology and biomechanical factors like patella alta or wide quadriceps angle.
Conclusions:
- The modified Roux-Elmslie-Trillat procedure is effective in reducing recurrent patellar subluxations.
- Patient outcomes are closely linked to the presence of intraarticular pathology and pre-existing biomechanical issues.
- Refined indications and slight modifications to the procedure may further optimize results.
