Medical history: Presentation at clinic on 25.06.2024. Lameness of left hindlimb since 1 year. Intermittent, often after a walk or when inactive. During activity/playing the dog shows nothing. It got worse since 3-4 months, it is progressive. It happens more often that he doesn't put any weight at all on his left hindlimb (always in the same conditions as before). He shows no expression of pain. The private vet took x-rays of the stifle and referred the case to us. The dog got NSAIDs when needed for 2-3 weeks, last time they were given at the end of the week before presentation. The dog goes no longer lame at all with NSAIDs. Here at the clinic x-rays were taken. X-rays report (25.06): Moderate osteoarthritis of the right stifle joint with moderate peri/articular swelling; Mild osteoarthritis tibiotarsal joint -> Findings compatible with degenerative joint disease of the right stifle joint possibly due to (partial) cranial cruciate ligament rupture; Associated meniscal and other ligament injury are also possible; Joint distension due to effusion, synovial hypertrophy or a combination of the two. An arthroscopy & TPLO were planned for the 15.08.2024. On that morning Raïka was brought to the clinic and the surgery was performed and the dog was released the day after surgery.
