Comparison of Surgical Treatment Options for Cranial Cruciate Ligament Disease in Large‐Breed Dogs with Excessive Tibial Plateau Angle

Abstract

Postoperative TPA<or=14 degrees and addition of ancillary implants are recommended when using TPLO to treat dogs with eTPA.

Preliminary experiences of the triple tibial osteotomy procedure: tibial morphology and complications

“…The distance of the tuberosity from the joint was defined by line X. To allow comparison between dogs of different sizes, this distance was normalised using a corrective ratio with the length of the tibial plateau, which has been previously used as a corrective ratio when assessing tibial morphology (Duerr and others 2008). Thus, any possible position of the tuberosity relative to the approximate centre of the stifle joint could be defined.…”

Extracapsular articulating implant to treat cranial cruciate ligament disease in a dog with multiple myeloma

“…Moreover, the tibial plateau angle, at 35°, would be considered an ‘excessive tibial plateau angle’ (eTPA) resulting in increased cranially directed shear force acting on the tibia with respect to the femur 37. A study12 comparing surgical techniques (TPLO, TPLO+ECS, TPLO+CCWO [cranial closing wedge osteotomy]) to treat dogs with CrCL disease with an eTPA did not include cases treated with ECS as a stand-alone option. The authors submit that the eTPA in this dog reduced the likelihood of success with ECS, although there are no published data on which to directly base avoidance of ECS in dogs with eTPA.…”

“…In this case radiographs were also indicated to exclude bone lysis in the region of the stifle, which might result from multiple myeloma. Radiographs of the left stifle had been acquired at the time of right TPLO planning (two years previously), and the tibial plateau angle had been found to be high at 35° 12. Arthroscopy might be utilised to examine the intra-articular structures, confirming CrCL disease and determining the extent of any meniscal trauma.…”

Electrocautery technique for proximal tibial epiphysiodesis in Labrador retriever puppies: experimental study

“…These techniques do not restore the function of the ligament but provide functional joint stability during weightbearing activities (Talaat et al, 2006;Boyd et al, 2007;Christopher et al, 2013). The tibial plateau leveling osteotomies attempt to reduce the tibial plateau angle by correcting it to a new angle of approximately 5º (Fettig et al, 2003;Duerr et al, 2008). By changing the slope of the tibial plateau, the cranial tibial thrust can be controlled (Kim et al, 2008).…”

“…It also prevents joint hyperextension, excessive internal rotation of the tibia and varus or valgus motion (Slocum and Slocum, 1993). One of the most common joint disorders in dogs is a CCL rupture (Kergosien et al, 2004;Shahar and Milgram, 2006;Duerr et al, 2008) which leads to hind limb lameness and degenerative joint disease (DJD) (Robinson et al, 2006;Bergh et al, 2008;Boudrieau, 2009). …”
