    Prevalence and outcome of meniscal tears identified during treatment for cranial cruciate ligament disease via tibial tuberosity advancement
    (2022) Silveira, Valeria Cristina da Silva; Santana, Ana Paula Álvaro, orient.
    Cranial cruciate ligament disease is a common condition of hindlimb lameness in dogs and it has a significant caseload on veterinary medicine. The objective of this study was to evaluate the prevalence of meniscal tears and its outcome after 4 weeks. This is a retrospective study based on 72 dogs where the prevalence of meniscal tears was 33% (24/72), being 83% (20/24) “bucket handle” tears. Those rates are comparable with recent literature reports. Breed, weight, age and preoperative PTA had a significant prevalence on cruciate disease and meniscal injury. Retriever breeds, overweight, middle-aged dogs and PTA over 100° were predisposing factors on this study. Meniscal tears were identified via arthrotomy, consequently caudal horn and internal tears of the medial menisci could have been misdiagnosed, explaining the outcome of higher rate of lameness on no concurrent tears (71%). MRI was not available on this study due to costs. Meniscectomy or hemimeniscectomy were the surgical treatment for meniscal tears, but the consequence of it on increasing contact pressure zone and alteration on biomechanical forces the osteoarthritis generally gets worse afterwards. For this reason, new researches have been done to improve cartilage and meniscal regeneration through tissue engineering with promising results.
