Die Desmotomie des medialen Kniescheibenbandes zur Therapie der pathologischen proximalen Patellafixation – Eine Studie bei Pferden und Ponys

pathologische, radiologisch Operation Patienten konnten Rezidive Operation früheren Funktion eingesetzt. Die Reparationsfähigkeit der Kniescheibenbänder konnte palpatorische Befunde bestätigt Postoperativ verschiedene radiologische Veränderungen im Bereich Patella und des Margo cranialis der Crista tibiae festgestellt, bei unseren Patienten ohne klinische Relevanz waren. Bei der untersuchten Ponys konnten radiologische Veränderungen festgestellt Mit 2 Ausnahmen alle Besitzer mit dem Operationsergebnis Clinical patellar In this study the clinical and radiological evaluation of 21 equine patients with medial patellar desmotomy is reported. The group consisted of 15 horses and 6 ponies of various breeds and the age ranged from 3 to 19 years. The desmotomy was performed on the standing sedated horse (except the minishetland horses, where the surgery was done under general anaesthesia) and NSAIDS were given post-operatively. All horses were rested or hand walked for 47 days until resuming work. At the time of the study the desmotomy has been performed 2 months to six years ago. The operation had been succesfull in all patients and no reoccurence of proximal patella fixation was observed. Most of the animals (19/21) went back to their original work including dressage, show jumping, circus and pleasure riding. Two patients were lame at the time of the examination, in one case the cause of the lameness was identified as a bonespavin, the other horse had lesions in the femorotibial joint. The radiologic evaluation, which was compared to the pictures before desmotomy, showed several pathologic changes of the patella and the margo cranialis of the crista tibiae, but were of no clinical consequence. None of the ponies showed any radiologic changes. Manual palpation revealed a fibrous structure on the medial aspect of the stifle joint at 4 months after desmotomy suggesting reparation tissue of the medial patella ligament by this time. Most owners (19/21) were satisfied with the outcome of this treatment. This study demonstrates that the medial patellar desmotomy is an effective treatment of the pathological proximal patellar fixation in equines. The post-operative mangement seems to be of great importance for the outcome of this treatment.
