ABSTRACT
INTRODUCTION:
Patellofemoral instability is a common knee disease. Its etiology is complex and variable, with many components making different contributions in each individual, resulting in several distinct clinical presentations. Our goal was to analyze the results of surgical treatment in our hospital over a period of 10 years. PATIENTS ANDMETHODS:
We analyzed 55 knees of 47 patients who underwent surgery for patellofemoral instability and were classified into 2 main groups proximal realignment and combined proximal and distal realignment. Three other groups were analyzed according to the duration of preoperative symptoms less than 1 year (group I); 1 to 10 years (group II); and more than 10 years (group III).RESULTS:
There were 62 percent good results overall, with 78 percent good results in groups I and II. Group III had 81 percent bad results, showing that a late diagnosis of advanced disease results in a poor prognosis. In addition to late diagnosis, bad results were usually associated with incorrect diagnosis or choice of surgical technique. There was no significant difference between isolated proximal realignment and combined proximal and distal realignment in groups I or II, but in group III, the combined technique yielded better results.DISCUSSION:
Our results indicate that patellofemoral instability should be addressed in its early stages. Patients with long-lasting symptoms or more severe disease seem to achieve better results with combined techniques.CONCLUSION:
Proximal and distal realignments produce better results than isolated proximal realignment in patients with joint degeneration or with greater duration of disease. The realignment surgery does not produce good results in patients with advanced disease
