Extensor mechanism problems in patellar surface replaced total knee arthroplasty patients

Year 1998, Volume: 32 Issue: 4, 287 - 290, 11.09.2006

Abstract

In this study we recorded the complications of extensor mechanism in 534 patients whose 584 knees were operated and patellar reconstruction was done between May 1988 and June 1997. Mean follow-up time is 51.5 months. Patellofemoral complications were occured in 7% of patients. There was patellar subluxation in 18 patients, patella infera in 12 patients, heterotopic ossification localised in extensor mechanism in 6 patients, fracture of patella in 2 patients and loosening, synovial construction and rupture of patellar tendon in one patient. Lateral retinacular release and medial capsular plication was the preferred method in 8 patients who had sympthomatic subluxation where as reconstruction was done in a patient whose patellar tendon was ruptured. There wasn't any reconstructions applied, depending on the patellar component complications. As a result we agreed that if technical pecularities like patello-femoral tracking and prevention of patellar blood supply are taken into consideration the complications can be minimized.

Patellar yüzeyi değiştirilen total diz protezi olgularında ekstansör mekanizma sorunları

Abstract

Bu makalede, Mayıs 1988 ile Haziran 1997 tarihleri arasında patellar yüzeyi değiştirilerek total diz pro-tezi konmuş 534 olgunun 584 dizinde ortalama 51.5 ay rakip sonrasında karşılaşılan ekstansör mekanizma ile ilgili komplikasyonlar bildirilmiştir. Olguların %7'sinde patellofemoral eklemi ilgilendiren sorunlar görülmüştür. 18 olguda patellar subluksasyon, 12 olguda patella infera, 6 olguda ekstansör mekanizmada lokalize heterotopik ossifikasyon. 1 olguda patella kırığı, gevşeme, sinovyal sıkışma ve parellar tendon rüptürü ise birer olanda tespit edilmiştir. Semptomatik subluksasyonlu 8 olgumuzda lateral retinakular gevşetme ile birlikte medial kapsül plikasyonu yapılırken, patellar tendon rüptürü olan olgumuzda ise rekonstrüksiyon tercih edilmiştir. Sadece patellar komponente yönelik revizyon hiçbir olguda yapılmamıştır. Patellofemoral uyum ve patellar dolaşımın korunması gibi teknik özelilklere dikkat edildiğinde ekstansör mekanizmadaki komplikasyonların azalacağı düşüncesindeyiz.
