The purpose of this study is to evaluate the results obtained from three surgical techniques (retinacular imbrication, trochleoplasty and tibia tuberosity transposition), which were simultaneously applied for correction of patellar luxation. Eleven, (6 to 108 months) old dogs were presented. The dogs showed, medial patellar luxation (17 stifle joint) and lateral patellar luxation (2 stifle joint) ranging from grade 1 to 4. By palpation and radiographic view, all 11 dogs were diagnosed as patellar luxation. Bilateral patellar luxation was diagnosed in 8 dogs. After operation, the dogs were monitored daily for 7 days and on the 10th, 15th, 20th, 25th and 30th days. Lameness progressively decreased in all dogs around 30 days after surgery, and the patients were showed normal walking. Normal walking was possible in 2 dogs after 4 days, in a dog after 5 days, a dog after 7 days, 3 dogs after 10 days,2 dogs after 15 days, a dog after 25 days and a dog after 30 days (Mean$\pm$S.E: 12.27$\pm$2.57). The recovery took 14 days in dogs with bilateral patellar luxation, and 9 days in dogs with unilateral patellar luxation. Trend of decrease of lameness grade in bilateral patellar corrected dogs were similar to that in unilateral patellar corrected dogs. Swelling, pain and fever disappeared on 7 days. In conclusion, combination of tibial tuberosity transposition, retinacular imbrication and trochleoplasty is appropriate for dogs with patellar luxation.

This study was performed to assess therapeutic effect of the tibial plateau leveling osteotomy (TPLO) in dogs with experimentally transected cranial cruciate ligaments (CrCL). Nine healthy adult Beagle dogs were transected left CrCL under general anesthesia. The dogs were assigned to TPLO and non-TPLO control groups. The TPLO procedures for correcting the CrCL rupture in the left stifle of dogs were performed under sterile conditions. Before TPLO procedures, all dogs were screened by orthopedic and radiographic examinations. Dogs were lameness free for the previous three months, and when examined at the walk and trot on a hard surface, in a straight line and on a circle. Lateral and craniocaudal radiographs were done to confirm the soundness of the both knee joint in dogs and not detectable lesions were diagnosed. The dogs were intravenously injected with a 10 mci/kg of 99mTechnetium-methylene diphosphonate (99mTc-MDP) under general anesthesia. Scintigraphs were obtained using a large field of view gamma camera equipped a parallel-hole, low-energy about 3 hours after intravenous injection of 99mTc-MDP. Before CrCL transection and 4, 8, and 12 weeks after the procedures, scintigraphy were conducted. Bone uptake of the left stifle joint increased after the procedures in all dogs. When the bone uptake from the TPLO procedure was compared with that of the control, there was a significant difference (p < 0.05). At 12 weeks after the TPLO procedure, the dogs showed normal anatomical posture and gait. It is concluded that TPLO procedure was effective in reconstruct of the stifle joint in dogs with CrCL rupture.

The morphogenesis of the stifle joint in Korean cattle embryos and fetuses was observed by radiography, alizarin red S stain and light microscopy. Fourty-eight(48) embryos and fetuses, ranging from 11mm to 160mm in crown-rump length (C-R L), were used for this study. The experimental samples were divided into twelve separate groups according to their C-R L. The first to the nineth group ranged from 11-100mm in C-R L, spaced at 10mm intervals. The tenth to the twelfth group ranged in C-R L from 101mm to 160mm, and were spaced at 20mm intervals. The results were as follows; 1. The first appearance of the interzone between the femur and tibia was formed in the second experimental group. The patellar ligament and cruciate ligament appeared in the third group and the patella, menisci and synovial cavity appeared in the fourth group. 2. The lateral and medial menisci were first obseved in the fourth group, and these structures showed crescent shape in the fifth group of the fetuses. 3. The first appearance of the femoro-tibial joint cavity was in the third group. The fifth group contained the first appearance of the patello-femoral cavity. Also, the femoro-tibial cavity was divided into two cavities by the anterior and posterior cruciate ligament.

The objective of this study was to establish kinematic reference ranges for the femorotibial (FT) joint and the patellofemoral (PF) joint in healthy small-breed dogs by measuring 3D kinematics at the walk. Single-plane fluoroscopy was used to image the stifle joints of five healthy beagle dogs while the dogs were walking. 3D bone models of the femur, patella, and tibia were reconstructed by computed tomography scanning of the beagle dogs' hind limbs. The shape-matching technique was used to measure kinematic data from the fluoroscopic images and the 3D bone models. The cranial translation of the tibia during walking was inversely proportional to the FT joint flexion. There were significant correlations between the patellar motion and the tibial motion. The FT joint flexion had a strong correlation with the patellar proximodistal translation and flexion. Additionally, the tibial mediolateral translation had a strong correlation with the patellar shift and tilt. In this study, normal in vivo 3D FT joint and PF joint kinematics were demonstrated, and the average kinematic parameters were determined in walking beagle dogs.

A male mixed breed dog with unknown age (case 1) and 5-year-old female golden retriever (case 2) were admitted to the Department of Veterinary Pathology at College of Veterinary Medicine, Seoul National University after sudden death. At necropsy, stifle region of case 1 was replaced by coalescing firm tan nodules approximately 1-3 cm in diameter. Neoplastic nodules were also presented in the lung. In case 2, the spleen was enlarged 3-5 times its normal size and numerous firm tan nodules were noted in the kidney, pericardium, diaphragm and lymph nodes. Histopathologically, the neoplastic masses of case 1 consisted of plump spindle cells having abundant cytoplasm and indistinct cell borders that formed interlacing bundle. In case 2, the masses were consisted of round to polygonal cells with abundant eosinophilic cytoplasm and eccentric nuclei. Numerous multinucleated giant cells containing nuclei of various sizes were noted. Immunohistochemically, neoplastic cells of all two cases stained intensely with vimentin and lysozyme. Based on the gross and light microscopic findings together with immunohistochemistry, both cases were diagnosed as localized histiocytic sarcoma with pulmonary metastasis and disseminated histiocytic sarcoma, respectively.

Background: Hyperbaric gaseous cryotherapy (HGC) is a type of cryotherapy used in human medicine for rehabilitation after orthopedic surgeries. Because HGC is known to reduce acute or chronic pain, research is needed to prove its effectiveness in veterinary medicine. Objectives: To compare the effects of HGC between the HGC treatment group and the nontreatment (NT) group on postoperative swelling, range of motion, lameness score, postoperative pain, and kinetic measurements after stifle joint surgery in dogs. Methods: Dogs were randomized in an HGC group or NT groups. In the HGC group, HGC was applied once a day for a total of 2 days after surgery. All parameters were measured postoperatively and at 1, 2, 10, and 28 days after surgery. Results: Twenty dogs were enrolled: 10 in the HGC group and 10 in the NT group. Soft tissue swelling was not significantly different between groups at any time point. In the HGC group, pain scores decreased significantly 24 h after surgery and 48 h after surgery. Dogs in the HGC group showed a significantly decreased lameness and improvement for all kinetic measurements beginning 48 h after surgery. In addition, the HGC group indicated a significant increase in range of motion as compared with the NT group at 28 days after surgery. Conclusions: HGC plays a powerful role in decreasing initial postoperative pain. Furthermore, the improvement in pain affects the use of the operated limb, and the continued use of the limb eventually assists in the quick recovery of normal function.
