Study examines coaptationless stifle reconstruction in cats

A new retrospective case series in Veterinary Surgery describes a coaptationless stifle reconstruction approach for cats with multiligament stifle injuries, a rare but severe form of traumatic stifle luxation. The study, published online February 27, 2026, reviewed 23 cats treated with ligament-specific reconstruction: TightRope stabilization for cranial cruciate and lateral collateral ligament injuries, intra-articular reconstruction for caudal cruciate ligament damage, and knotless anchors for medial collateral ligament repair. Initial stabilization was achieved in all cases, and follow-up through 6 months found lameness ranging from mild to undetectable, with high feline musculoskeletal pain index scores. Six major complications were reported, including four cases of recurrent caudal cruciate instability and two cases of medial patellar luxation; all but one were resolved with revision surgery.

Why it matters: Feline stifle luxation is typically associated with high-energy trauma and often involves multiple ligament injuries, meniscal damage, and other concurrent injuries, which can make repair and postoperative management difficult. Prior literature has described substantial short-term complication rates and noted that postoperative coaptation can be hard to maintain and may contribute to bandage-related injury, while a 72-cat multicenter study found no clear benefit from postoperative immobilization. This new series suggests that, when each injured ligament is reconstructed directly, some cats may regain stability without temporary immobilization, which could reduce the morbidity tied to casts, bandages, or transarticular fixation in carefully selected cases.

What to watch: The next question is whether larger, comparative studies can confirm which cats benefit most from a coaptationless approach, especially when the caudal cruciate ligament is deficient. (pubmed.ncbi.nlm.nih.gov)
