Abstract		Surgical treatment of four horses by means of an upward fixation of the patella has been described. A desmotomy of medal patellar ligamen has performed. When resting, the horse's patella hooks temporaarily over the dorsal medial trochlear ridge. This has been described as some kind of a lock of the horse's knee joint. Whenever the horse feels a need to relax the patella from the described position, he contracts m. quadriceps femoris, lifts the patella from the described position and returns it, after relaxing the muscle, into the trochlear groove. In case of a disturbed coordination of relaxing the patella from the described position, the animal does not flex the affected extremity. Clinically, the signs of an animal with a dorsal fixation of the patella, are fairly typical. The affected limb is visibly extended backwards. The horse can lean on the affected limb just with the front part or the dorsal wall of the hoof. In the past five years, dorsal fixation of the patella in the horse has benn performed at the Clinic of the Veterinary Faculty of Ljubljana in three Thooughbreds and one pony horse. All horses have been treated surgically by means of desmotomy which was performed on the standing animal. After surgery the animals rested 4 do 6 weeks. By means of a questionnaire we found out that in all cases the treatment was successful.
Summary		V prispevku so opisani primeri kirurškega zdravljenja štirih konj s proksimalno fiksacijo pogačice. Opravljena je bila dezmotomija medialnega patelarnega ligamenta. Med počivanjem se konju pogačica začasno zaskoči and medialnim trohlearnim grebenom. Pojav opisujejo kot nekakšen zaklep konjskega kolenskega sklepa.. Če ima konj potrebo po sprostitvi pogačice, skrči m. quadriceps femoris, dvigne pogačico iz opisanega položaja in jo po sprostitvi mišice vrne v trohlearni žleb. V primeru, če je korrdinacija sproščanja pogačice iz opisanega položaja motena, žival prizadete noge ne skrči. Klinična slika žvali s proksimalno fiksacijo pogačice je precej značilna. Prizadeta noga je izrazito iztegnjena nazaj. Na prizadeto nogo se lahko žival naslanja le s prednjim delom ali z dorzalno steno kopita. Proksimalne fiksacije pogačice pri konjih so bile na kliniki Veterinarske fakultete v Ljubljani zdravljene v zadnjih petih letih pri treh toplokrvnih konjih in enem poniju. Vse konje smo zdravili kirurško z dezmotomijo. Poseg smo opravili na stoječih živalih. Po operacijskem posegu so živali počivale še 4 do 6 tednov. Iz ankete smo ugotovili, da je bilo zdravljenje v sveh primerih uspešno.
