Experiences in diagnostic and surgical arthroscopy in the horse

Abstract

Summary This paper reviews the current status of diagnostic and surgical arthroscopy in the horse. Arthroscopy has been used as a diagnostic aid since 1974 and is useful for evaluation of abnormalities in synovial membrane and articular cartilage. Surgical arthroscopy is a more recent advance that has replaced conventional arthrotomy in 90 per cent of the author's cases. Clinical conditions currently being treated using arthroscopic techniques rather than arthrotomy include all chip fractures in the carpus, chip fractures of the first phalanx, chronic proliferative synovitis in the fetlock and osteochondritis dissecans of the femoropatellar and tibiotarsal joints. The equipment requirements and basic techniques are reviewed. Convalescent time following surgery is decreased and the cosmetic appearance improved compared to arthrotomy. Considerable experience is required for competent surgery which, in turn, is necessary for this method to have advantage over previous conventional techniques.

Arcabouço de PRP-gel associado a células tronco mesenquimais: uso em lesões condrais em modelo experimental equino

“…A técnica artroscópica utilizada foi a proposta por Mcilwraith (2005). Para criar a lesão foram utilizadas lâminas abrasivas motorizadas (broca circular Razek 2,9/5,5 -Razek Equipamentos, Brasil) e pinças artroscópicas, com desgaste controlado, suficiente para obter a dimensão da lesão condral desejada.…”

Plasma rico em plaquetas no tratamento de lesões condrais articulares induzidas experimentalmente em equinos: avaliação clínica, macroscópica, histológica e histoquímica

“…Foram estabelecidos dois portais, de acordo com a técnica descrita por McIlwraith (2005a). Pelo portal artroscópico primário, foi inserida a óptica para inspeção articular, e, pelo portal instrumental, foram realizados a lesão condral, o implante dos tratamentos e a coleta das amostras para os exames histopatológicos e histoquímicos.…”

Mesenchymal stem cell enhances chondral defects healing in horses

“…Eight patellofemoral joints of both hind limbs of four healthy horses were submitted to arthroscopic surgery [16] to produce a chondral defect. These defects were treated according to the group: Group G1 (four joints) were administered autologous implants of MSC in fibrin glue; G2 (four joints) constituted the experimental control group.…”
