Congenital Unilateral Lateral Patellar Luxation in a Simmental Calf

Abstract

In this case report, the surgical treatment of a calf with congenital, unilateral lateral patellar luxation with clinical, radiography, and computed tomography findings is presented. A 5-day-old calf was referred due to an extremely flexed knee joint with hindlimb weakness. Radiographic, computed tomographic, and orthopedic examination demonstrated a grade 3 unilateral lateral patellar luxation with normal stifle bone anatomy. Surgery includes lateral release with medial imbrication of the medial retinaculum and resulted in the repositioning of the patella. After the surgery, the limb was immobilized for ten days. The calf became a normal stance and gait following six weeks after the surgery. In conclusion, lateral release with medial imbrication of the medial retinaculum can be effective just for the treatment of lateral patella luxation in calves.

Bir Buzağıda Kongenital Unilateral Lateral Patella Luksasyonu

Öz

Bu olguda, konjenital ve unilateral patella luksasyonu bulunan bir buzağının, cerrahi sağaltımı ile birlikte klinik, radyografik ve bilgisayarlı tomografi bulguları sunulmaktadır. Beş günlük bir buzağı, arka ayaklarında güçsüzlük ile diz ekleminde aşırı fleksiyon şikayetiyle getirildi. Radyografik, bilgisayarlı tomografi ve ortopedik muayene sonucunda diz eklemi kemiklerinin anatomik olarak normal olmasıyla beraber, unilateral 3. derece bir patella luksasyonu olduğu belirlendi. Cerrahi olarak, medial retinakulumun ile birlikte medial imbrikasyonu ve lateral serbestleştirme işlemleri uygulanarak patellanın yeniden konumlandırılması sağlandı. Operasyon sonrası buzağının eklemi 10 gün süreyle sabitlendi. Operasyondan altı hafta sonra hayvan normal olarak ayağını kullanabildiği gözlemlendi. Sonuç olarak, lateral serbestleştirme ile medial imbrikasyon buzağılarda lateral patella luksasyonları tedavisi için tek başına yeterli olabilmektedir.
