Combined intra- and extracapsular stabilization for CCL rupture in a toy-breed dog: a case report.

Non-osteotomy-based stabilization is effective for CrCL rupture in ultra-small dogs.

Cranial cruciate ligament (CrCL) rupture is a common cause of hindlimb dysfunction in dogs, particularly affecting toy breeds. Traditional surgical interventions like tibial plateau leveling osteotomy (TPLO) are often unsuitable for small dogs due to anatomical constraints and implant limitations. This case report details the treatment of a 10-year-old, 2.0 kg Maltese dog with CrCL rupture and underlying cardiac disease, for whom osteotomy was contraindicated. A hybrid stabilization technique was employed, combining intra-articular suture placement with extracapsular anchoring via bone tunnels, intentionally avoiding the use of the lateral fabella. The procedure resulted in rapid postoperative limb function recovery and no observed complications. This outcome underscores the potential clinical value of non-osteotomy-based stabilization methods in ultra-small dogs, especially when traditional techniques pose excessive risk. Further case accumulation and long-term monitoring are necessary to validate the safety and efficacy of this approach.
