Influence of TPLO and tibial tuberosity advancement on passive laxity of the cranial cruciate deficient stifle in dogs
Authors: Ober CA, Factor G, Meiner Y, Segev G, Shipov A, Milgram J

OBJECTIVE: To evaluate the effect of tibial plateau leveling osteotomy (TPLO) and tibial tuberosity transposition (TTA) on craniocaudal stability of the cranial cruciate ligament (CCL) deficient stifle at 3 joint angles.

STUDY DESIGN: Ex vivo biomechanical study.

Suspected Compartment Syndrome, Consumptive Thrombocytopenia, and Anemia Secondary to a Ruptured Arterial Aneurysm or Pseudoaneurysm Following Multiple Stifle Surgeries
Authors: Levenson M, Calabro JM, Crawford JR, Hart SK

A 12 yr old male neutered beagle was presented on transfer to the intensive care unit with severe anemia, thrombocytopenia, and bruising detected 1 day after undergoing tibial plateau leveling osteotomy surgery. The patient had undergone extra-capsular stifle stabilization surgery 14 wk prior to treat ligament disease in the same knee.

Authors: Adrian CP, Haussler KK, Kawcak CE, Reiser RF 2nd, Riegger-Krugh C, Palmer RH, McIlwraith CW, Taylor RA.

OBJECTIVE: Identify relevant electromyography (EMG), kinematic, and kinetic changes resulting from monopolar radiofrequency energy (MRFE)-induced cranial cruciate ligament (CCL) injury and eventual rupture in dogs.

STUDY DESIGN: Experimental, repeated measures.

Evidence of genetic contribution to patellar luxation in Toy Poodle puppies
Authors: Maeda K, Inoue M, Tanaka M, Momozawa Y.

Patellar luxation (PL) is one of the most common orthopedic disorders in dogs and a genetic factor is considered to play an important role in the development of PL. Genomic analysis has attempted to identify the genetic markers associated with the development of PL but only suggestive markers have been identified. Carefully selecting breeds with higher incidence rates of congenital PL as well as affected dogs with more severe symptoms are required, but such information remains limited to date.

Histologic assessment of ligament vascularity and synovitis in dogs with cranial cruciate ligament disease
Authors: Kuroki K, Williams N, Ikeda H, Bozynski CC, Leary E, Cook JL.

OBJECTIVE: To assess the relationship between histologic degeneration of cranial cruciate ligaments (CCLs) and severity of synovitis and ligament vascularity.

SAMPLE: CCL and synovium from 59 stifle joints (53 dogs).

Effect of tibial rotation on the tibial plateau angle measurement in dogs: An ex vivo study
Authors: Buirkle CL, Aulakh KS, Gines JA, Rademacher N, Liu CC, Barnes K.

OBJECTIVE: To determine the effect of tibial rotation on radiographic tibial plateau angle (TPA) measurement in normal and cranial cruciate ligament (CrCL)-deficient stifles.

STUDY DESIGN: Cadaveric study.

SAMPLE POPULATION: Five pairs of canine cadaver hind limbs with no stifle osteoarthritis.
