Study reports coaptationless stifle reconstruction in 23 cats

A new retrospective case series in Veterinary Surgery describes a coaptationless, multiligament stifle reconstruction technique for cats with traumatic stifle luxation, using an internal brace-style approach tailored to each injured ligament. The study, from Sebastian C. Knell, Philipp A. Schmierer, and Antonio Pozzi at the University of Zurich and Tierklinik Posthausen, included 23 cats with rupture of two or more stabilizing ligaments. Initial stabilization was achieved in all cases, and the authors reported generally good short-term outcomes without postoperative joint immobilization. Major complications occurred in six cases, most commonly recurrent caudal cruciate instability, and one cat ultimately required arthrodesis. (pubmed.ncbi.nlm.nih.gov)

Why it matters: For veterinary professionals, the paper adds to a small but clinically important body of evidence around feline multiligament stifle injury, a severe but uncommon trauma pattern that has historically been managed with techniques that often include temporary transarticular fixation or postoperative immobilization. Prior multicenter data in 72 cats found high short-term complication rates, including recurrence, pin-related problems, fractures, and amputations, while a review of severe stifle trauma has noted the long-term downsides of immobilization. This new series suggests that, when each deficient ligament is specifically reconstructed, some cats may be stabilized successfully without coaptation, though the caudal cruciate appears to remain a key failure point.

What to watch: The next question is whether larger, longer-term comparative studies can confirm whether coaptationless reconstruction improves function and reduces complications versus more traditional stabilization strategies. (pubmed.ncbi.nlm.nih.gov)
