Intra‐articular biomaterial injection as a management option for canine stifle disease: navigating the evidence gap

Intra-articular biomaterial injection as a management option for canine stifle disease: navigating the evidence gap MANAGING cranial cruciate disease (CCD) and its inevitable sequela, stifle osteoarthritis (OA), remains one of the most contentious areas in veterinary orthopaedics.For decades, the conversation has centred on a binary choice: surgical stabilisation or conservative management.However, a recent proof-of-concept study by Kleeman and colleagues, 1 summarised on p 426 of this issue of Vet Record, introduces a third, albeit controversial, option: intra-articular biomaterial injection as a palliative strategy for dogs where surgery is deferred.Kleeman and colleagues' study 1 signals a growing interest in non-cellular orthobiologic approaches for joint pain and prompts a necessary reflection on how veterinarians adopt emerging therapies.Canine CCD is not merely a mechanical failure.The dysregulation of synovial cell function and the rapid progression of OA, with osteophyte production occurring within seven days in experimental models, 2 mean that simply addressing joint instability does not fully resolve the underlying inflammatory cascade.Surgical procedures such as tibial plateau levelling osteotomy remain the gold standard for restoring function, particularly in medium-to-large breed dogs, by neutralising tibiofemoral shear forces.3 However, surgery carries substantial financial, logistical and emotional burdens for owners.Many owners are unable to pursue surgical treatment, either because it is unaffordable or because their dog is ineligible due to anaesthetic complications.Complications, including surgical site infections and implant failure, are also not negligible, and many owners either cannot afford or cannot accommodate the postoperative demands.Even if a dog is eligible for surgery and its owners can afford the procedure and meet postoperative demands, circumstances may require postponing it.This is particularly
