Lateral luxation of the patella has been described in horses and ponies. Medial luxation has been reported only twice. Upward fixation of the patella is not true luxation. This report concerns two cases of lateral luxation of the patella related to hypoplasia of the lateral ridge of the trochlea of the femur.

Five dogs of varying breeds and ages were presented for evaluation of medial patellar luxation that was unresponsive to conservative treatment. Arthroscopy of each affected stifle was performed, and adequacy of the femoral trochlea and patellar tracking in the trochlea were assessed. Medial femoropatellar ligament release was then performed using a bipolar radiofrequency electrosurgical system ...

The patella is an ossification in the tendon of insertion of the quadriceps femoris muscle. It works along with the femoral trochlea as a pulley, redirecting the line of action of the quadriceps tendon. For the patella to be stable and to move in the most efficient direction, axial alignment of the extensor apparatus with the underlying skeletal elements is necessary. The extensor apparatus is ...

OBJECTIVE To determine the proportion of mixed-breed and purebred dogs with common genetic disorders. DESIGN Case-control study. ANIMALS 27,254 dogs with an inherited disorder. PROCEDURES Electronic medical records were reviewed for 24 genetic disorders: hemangiosarcoma, lymphoma, mast cell tumor, osteosarcoma, aortic stenosis, dilated cardiomyopathy, hypertrophic cardiomyopathy, mitral v...

The patella is a motorical important part of the feline stifle joint. By gliding proximally and distally inside trochlear groove, its position continually changes during each step mobility. Stifle diseases like patellar luxation, cruciate ligament rupture, or tendon disease as well consecutive surgical interventions may cause dislocation.

Abstract A 75 kg, 4‐year‐old, male, neutered, Saanen‐cross, pet‐owned, adult goat presented for left trochlear sulcoplasty treatment of lateral patellar luxation. Premedication consisted intravenous butorphanol (0.2 mg/kg), and midazolam (0.5 mg/kg, intravenous), followed by ketamine (2 intravenous) propofol induction anaesthesia. Anaesthesia was maintained using isoflurane in oxygen (100%) mec...

A two-year-old male Pomeranian dog was presented to a veterinary hospital due the side effects of surgical correction for patellar luxation. Stifle joint arthrodesis (SJA) performed on patient’s right leg using autologous bone-grafting techniques. The femur and tibial were angled 120–130°, an SJA plate fixed front two bones. After performing fusion limb, medial-patellar-luxation-(MPL)-correctiv...

objectives: patellar maltracking is the main reason for pain and disability in patellofemoral pain syndrome (pfps). patellar taping can considerably reduce such pain and disability. this study compared the effectiveness of physiotherapy exercises and kinesio taping on the patellar position in women with pfps (mean age 32.2±1.12 years) by using magnetic resonance imaging (mri). methods: thirty w...

The purpose of this study is to describe complications affecting the patella in patients with total or partial knee arthroplasty. We respectively analysed plain-film radiographs, as well as ultrasound images when acquired, in a consecutive series of 1272 patients. The mean interval from knee replacement to patellar complications was 5 years and 7 months (range, 5 months to 14 years). The compli...
