Degenerative Joint Disease Evaluation in Feline Populations

Degenerative joint disease (DJD) in feline populations is a chronic, progressive condition characterised by the deterioration of articular cartilage and subchondral bone, leading to pain, reduced mobility and impaired quality of life. Once considered uncommon in cats, DJD is now recognised as highly prevalent, particularly in ageing and overweight individuals, often manifesting as osteoarthritis. Clinical evaluation encompasses a combination of owner-reported outcome measures, physical examination findings including joint palpation, gait assessment and objective metrics such as accelerometry and force plate analysis. Radiographic imaging remains the cornerstone for diagnosing structural changes, while advanced techniques—quantifying bone mineral density or profiling serum biomarkers—are expanding the toolkit. Recent developments have emphasised refined objective measures, biomarker discovery and novel imaging protocols, aiming both to improve early detection and to monitor therapeutic efficacy. This multidisciplinary approach has global relevance, as improving the welfare of cats with DJD informs comparative research and may translate to advancements in human musculoskeletal disease management.

Research from Nature Portfolio

A foundational clinical trial evaluated the efficacy of a novel non-steroidal anti-inflammatory agent in cats with DJD-associated pain, establishing suitable endpoints for future studies. In a randomised, blinded design, treated cats exhibited measurable increases in activity levels and significant reductions in owner-assessed disability and behavioural signs of pain over a six-week period. This work confirmed the validity of accelerometry and structured owner questionnaires as sensitive outcome measures, and highlighted the potential of targeted NSAID therapy to improve mobility and well-being in feline DJD.
