Dear All,
I would appreciate any information regarding the incidence of caudal meniscal root tears of the medial meniscus in dogs. The term meniscal root tear is an established term in human orthopaedics and is defined as bony or soft tissue root avulsion injury or radial tear within 1 cm of the meniscus root attachment = 1cm from the bony attachment of the meniscotibial ligament. In human, the incidence of caudal meniscal root tears is up to 21.5% of all injuries to the caudal pole (posterior horn) of the medial meniscus and because this injury leads to changes similar as with caudal meniscectomy, several treatment strategies exist in order to safe the functional unit of the meniscus (the meniscus self and its ligamentous apparatus).
The in the veterinary literature commonly used classification of meniscal injuries (Whitney 2003) seems to omit the location of the meniscal injuries in regards to the meniscotibial attachment and therefore I find difficult to draw any conclusions about incidence of the meniscal root injuries in canines from the veterinary epizootological studies (Ritzo et al. 2014, McCready and Ness 2016). However, knowledge of the incidence of such injuries would help to create a proposal of a study evaluating strategies for meniscus salvaging procedures by adapting some of the trending human orthopaedic techniques. Thank you very much for your help.
Dear Jakub, I just wondered if you got any replies to this query or if you have any new findings yourself? When we ultrasound scan meniscal injuries in dogs we characteristically see medial extrusion of the meniscus -which in people seems to be a feature of medial meniscal root tears with loss of 'hoop function'. I always get blank looks from orthopaedic surgeons when i suggest this! kind regards, Roger
Dear Roger,
Thank you for your reply. Unfortunately, your's was the first one I have got on the topic. I have been busy for the past year with some other research areas and therefore haven't advanced my understanding of this problem a lot. I do like your idea of using ultrasound as a way how to indirectly examine meniscal root tears and I will have to discuss this with our radiologist here in Vienna!
