Medical history: External consultation for radiographs 2 weeks ago: stifle right & left, pelvis. X-rays report (18.04.2024): Increased soft tissues within the left stifle joint and mild osteoarthritis; Minimal osteoarthritis femoropatellar joint right stifle; Moderate bilateral hip dysplasia with joint laxity and moderate osteoarthritis. Lameness hind left leg since a few weeks before presentation at the beginnin ng of may (so from april) after presumed trauma, no improvement with NSAIDs. First onsultation for MRI & x-rays for TPLO, then elective surgery was performed on the 17.05.2024. MRI report (03.05.2024): Complete cranial cruciate ligament rupture left stifle; Horizontal longitudinal tear in the abaxial border of the medial meniscus; Marked secondary stifle joint effusion with effusion within the long digital extensor tendon sheath and synovial thickening.
