RESUMO Os efeitos da eletroestimulação pós-operatória no processo de reparação de falhas osteocondrais induzidas no INTRODUÇÃOAs patologias que envolvem lesão da cartilagem articular estão freqüentemente associadas a prognóstico reservado, devido à dificuldade de plena regeneração da cartilagem hialina e à possível evolução para doença articular degenerativa, resultando em hipofunção da articulação e comprometimento do desempenho e bem estar do animal. Cães de raças de crescimento rápido,

Effect of electrical stimulation of the cranial tibial muscle after end-to-side neurorrhaphy of the peroneal nerve in rats

“…Electrical stimulation (ES) to promote regeneration, although controversial [11][12][13] , became a topic of study in functional muscle recovery, and may be used as a method of preventing muscle atrophy resulting from a period of muscle inactivity regardless if caused by denervation or not 9 .…”

“…Authors, such as Tagami et al 14 observed that the daily application of electrical stimulation in rats is beneficial for axonal regeneration and does not contribute to functional impairment, unlike some authors who have cited harmful effects of electrical stimulation, causing contractures and spasms [11][12][13] .…”

The use of PLDLA/PCL-T scaffold to repair osteochondral defects in vivo

“…Shapiro et al 33 suggested that the ability to maintain cartilage intactness in a healing joint depends on the reconstitution of excised bone tissue. Cartilage undergoing repair did not show the degenerative alterations observed in most of the 24-week post-operatory failures, except for a small number of animals in which subchondral bone was reconstructed 7 . Histological analysis revealed the nature of the neoformed tissue for each type of repair.…”

“…Each rabbit received the same treatment, i.e., the polymeric scaffold was implanted on the right leg while no material was implanted on the left leg, kept without treatment (control). The wound was sutured with 4-0 mononylon using simple interrupted stitches in the capsule and simple suturing in the skin 7,8 . The rabbits were sacrificed 4 weeks and 12 weeks (n = 6 to each group) after implantation with an overdose of halothane.…”

“…However, the natural healing of a lesion in joint hyaline cartilage (chondral defect) does not follow these phases, primarily because of the avascular condition of this tissue 7,8 . However, if such damage extends up to subchondral bone (which has adequate vascularization) then all three phases may occur 6 .…”
