Practical relevance: An understanding of the process of musculoskeletal ageing - which all senior and geriatric cats will experience - is vital to maintaining the health and welfare of our ageing cat population.
Long-term Outcome and Progression of Osteoarthritis in Uncomplicated Cases of Cranial Cruciate Ligament Rupture Treated by TPLO in Dogs
The object of this study is to evaluate the long-term outcome of hind limb weight-bearing function and progression of stifle osteoarthritis (OA) after tibial plateau leveling osteotomy (TPLO).
Groups were classified by the degree of cranial cruciate ligament (CrCL) damage and presence or absence of medial meniscus damage as macroscopically evaluated during surgery. Weight-bearing function was assessed via the peak vertical force (PVF), and OA progression was assessed via the radiographic OA score (OAS) preoperatively and 1, 3, 6, 12, 18, 24, and 36 months postoperatively.
Influence of orthopedic examination on lameness scores and interobserver and intraobserver agreement in dogs with naturally occurring elbow osteoarthritis
OBJECTIVE: To determine the influence of orthopedic examination on numerical rating score (NRS) and visual analog score (VAS) when scoring lameness in dogs with elbow osteoarthritis (OA) and to evaluate interobserver and intraobserver agreement in NRS and VAS on the basis of video-graph
Initiating factors for onset of OA: A systematic review of animal bone and cartilage pathology in OA.
There is controversy over whether bone or cartilage is primarily involved in osteoarthritis (OA) pathogenesis; this is important for targeting early interventions.
Joint stiffness due to fibrosis/capsule contracture is a seriously disabling complication of articular injury that surgical interventions often fail to completely resolve. Fibrosis/contracture is associated with the abnormal persistence of myofibroblasts, which over-produce and contract collagen matrices.
Intra-articular Injection of Chloramphenicol Reduces Articular Cartilage Degeneration in a Rabbit Model of Osteoarthritis
BACKGROUND: Osteoarthritis (OA) is characterized by degeneration of articular cartilage. Studies have found that enhancement of autophagy, an intracellular catabolic process, may limit the pathologic progression of OA.
Ligament laxity is a known complication of erosive immune-mediated polyarthritis (IMPA) in dogs. The purpose of this study was to describe the occurrence and clinical features of carpal or tarsal ligament laxity in cases of nonerosive IMPA in dogs for the first time.
Evaluation of Intravenously Delivered Allogeneic Mesenchymal Stem Cells for Treatment of Elbow Osteoarthritis in Dogs: A Pilot Study
OBJECTIVES: The aim of this study was to evaluate the safety and collect pilot data measuring clinical effects of intravenously administered, adipose-derived, culture-expanded, allogeneic mesenchymal stem cells in dogs with elbow osteoarthritis.
OBJECTIVE: To evaluate the influence of osteoarthritis on the measurement of patella tendon angle (PTA) and determine intraobserver and interobserver variability.
STUDY DESIGN: Retrospective clinical study.
SAMPLE POPULATION: Eighty-seven mediolateral radiographs that were obtained prior to tibial tuberosity advancement.
Intra-Articular Administration of Autologous Micro-Fragmented Adipose Tissue in Dogs with Spontaneous Osteoarthritis
Similar to the disease affecting humans, osteoarthritis (OA) is a painful musculoskeletal condition affecting 20% of the adult canine population. Several solutions have been proposed, but the results achieved to date are far from being satisfactory. New approaches, such as intra-articular delivery of cells (including mesenchymal stromal cells), have been proposed. Among the many sources, the adipose tissue is considered very promising.
