Surgery for cranial cruciate ligament disease is often recommended; however, it is unclear if one procedure is superior. The aim of this systematic review was to answer the a priori question, "Is there a surgical procedure that will allow a consistent return to normal clinical function in dogs with cranial cruciate ligament disease and is that procedure superior to others?" A systematic literature search was performed through September 2013. Peer reviewed publication in the English language and 6 mo of postoperative follow-up were required.

Disruption of the triceps tendon insertion is an uncommon injury, with only a few reports of traumatic triceps tendon avulsion in dogs or cats present in the veterinary literature. Although this injury has been previously described in two dogs that had received a local injection of corticosteroids for the treatment of soft tissue injuries, reports with long term clinical follow-up and outcome in working dogs are lacking. This report describes two surgically treated cases of complete triceps tendon avulsion rupture in Malinois police dogs.

Susceptibility artifacts caused by ferromagnetic implants compromise magnetic resonance imaging (MRI) of the canine stifle after tibial plateau leveling osteotomy (TPLO) procedures. The WARP-turbo spin echo sequence is being developed to mitigate artifacts and utilizes slice encoding for metal artifact reduction. The aim of the current study was to evaluate the WARP-turbo spin echo sequence for imaging post TPLO canine stiflejoints. Proton density weighted images of 19 canine cadaver limbs were made post TPLO using a 3 Tesla MRI scanner.

Low-field magnetic resonance imaging (MRI) is commonly used to evaluate dogs with suspected cranial cruciate ligament injury; however, effects ofstifle positioning and scan plane on visualization of the ligament are incompletely understood. Six stifle joints (one pilot, five test) were collected from dogs that were scheduled for euthanasia due to reasons unrelated to the stifle joint.

Dogs treated for congenital medial patellar luxation were reviewed for the purpose of determining the incidence of postoperative major complications requiring surgical revision and the risk factors for their occurrence. Major complications occurred in 18.5% of the patellar luxation stabilization procedures with implant associated complications being the most frequent, patellar reluxation the second, and tibial tuberosity avulsion the third most common major complication. Other complications included patellar ligament rupture and trochlear wedge displacement.

Objectives: To evaluate the degree of lateralization achievable and strength of tibial tuberosity transposition and advancement (TTTA) relative to pin and tension band wiring (PTBW) for lateral tibial tuberosity transposition. Methods: Six pairs of cadaveric tibiae were used. Tibial tuberosity position was determined with computed tomography (CT); bones were then randomly assigned into TTTA and PTBW groups. The PTBW group had a tibial tuberosity osteotomy and fixation with pin and tension band wiring.

Objective: Retrospective case series describing the surgical treatment and outcome in dogs with bicondylar femoral fractures complicated by ligament or tendon injuries. Methods: Medical records were reviewed for three immature and one mature dog with traumatic bicondylar fractures of the distal femur and concurrent ligament or tendon injury treated surgically. Data retrieved included physical examination, imaging, and treatment. Long-term follow-up and return to function was assessed by owner feedback, physical examination, radiology, and force plate analysis.

Objective: The aim of this study was to investigate the biomechanical effects of cranial cruciate ligament (CrCL) transection on stifle stability at three different stifle joint flexion angles using a robotic system. Methods: This was an ex vivo biomechanical study. Stifles (n = 6) were collected from the cadavers of Beagles weighing 10.5-12.0 kg. Six stifle joints were dissected, potted, and secured to the manipulator arms of a robotic simulator.

Objectives: To determine whether the medial collateral ligament can be a reliable intra-operative anatomical landmark for rotation of the tibial plateau in the tibial plateau levelling osteotomy (TPLO) procedure, thus providing a tibial plateau rotation equal to that obtained using standard preoperative measurements. Methods: Tibial plateau levelling osteotomy procedures were performed on pelvic limbs (n = 42) from canine cadavers with or without a history of cranial cruciate ligament deficiency.

OBJECTIVE:

To report clinical and histopathologic features of long digital extensor (LDE) tendon mineralization with concurrent cranial cruciate ligament (CCL) rupture in a dog.

STUDY DESIGN:

Case report.

ANIMAL:

1.5-year-old, male castrated, English bulldog mix weighing 31.5 kg.

METHODS:

Pre- and postoperative orthogonal radiographs, arthroscopic evaluation, arthrotomy with en bloc surgical excision, and histopathologic analysis of the excised LDE tendon.
