Distal Realignment of Patella by Elmslie-Trillat-Maquet Procedure for Recurrent Patellar Subluxation or Dislocation
並列摘要
Distal realignment of patella should be considered in cases of recurrent patelltar subluxation or dislocation with high Quadriceps angle (Q angle) after invalid nonsurgical treatment. A distal realignment operation , included medialization (Elmsile-Trillat procedure) and anteriorization (Maquet procedure) of tibial tubercle, was designed for reduction of Q angle and decompression of patellofemoral pressure simultaneously. There were eight knees in six patients, five males and one female, received this realignment operation. Six recurrent patellar subluxations with chondromalacia of patella and Q angle above 25 degrees were treated with Elmslie Trillat-Maquet procedure alone. One recurrent patellar dislocation with chondromalacia and high Q angle was corrected with Elmslie-Trillat-Mapuet procedure and distal advancement of vastus medialis. One post-traumatic dislocated patella with chondromalacia was managed with Emslie-Trillat-Maquet procedure and vastus medialis obliquus (V.M.O.) transfer. The average age at the time of Surgery was 22.4 years (range, 21 to 24 years). The average follow-up period was 20 months (range, 14 to 31 months). The result showed excellent in seven knees with pain free and good in one dislocated patella with mild pain. No recurrint subluxation or dislocation of patella developed postoperatively. The everage distance of anteriorization was 10.6 mm, and medialization was 12.4 mm. The average reduction of Q angle was 13.6 degrees. All postoperative Q angles were restorated within 15 degrees. Thus, Elmslie-Trillat-Maquet procedure is a good and effective procedure for the patellar subuxation or dislocation with high Q angle.
