Temporary Transarticular Immobilization of the Stifle Joint Using a Locking Plate.

Our study aims to describe the surgical technique for temporary transarticular immobilization of the stifle joint using a locking plate and evaluate complications and outcomes.The medical records of dogs and cats that underwent transarticular immobilization of the stifle joint using a locking plate in two institutions from August 2018 to January 2024 were retrospectively evaluated.After managing the primary injury, a locking plate was contoured to fit the medial surface of the distal femur and proximal tibia, limiting the implant to the distal third of the femur and proximal third of the tibia, with immobilization at a 135 to 145-degree angle.Temporary transarticular immobilization of the stifle joint was performed in 16 stifle joints in 14 patients, with two dogs undergoing bilateral surgery. The transarticular implants were removed at a mean time of 55,86 ± 18,05 days postoperatively (median: 58, range: 27-96 days). No intraoperative complications were recorded. One major complication was recorded in a Galgo Espanol with a patellar fracture and patellar ligament lesion in which plate breakage was recorded 19 days after surgery, requiring early plate removal and application of an orthosis for 3 weeks. Four minor complications were recorded.Preliminary results suggest that a transarticular locking plate is effective for temporary stifle immobilization, with a low morbidity and complication rate. Dedicated implants should be developed to decrease the risk of plate failure.
