OBJECTIVE: To determine the predictive value of meniscal click for specific meniscal tear morphology.

STUDY DESIGN: Prospective cohort.

ANIMALS: Client-owned dogs (104) with cranial cruciate ligament (CCL) deficiency treated with stifle arthroscopy (111).

Authors: Rossanese M, German AJ, Comerford E, Pettitt R, Tomlinson A, de Vicente F.

OBJECTIVE: The main aim of this study was to describe complications in dogs weighing < 20 kg treated for medial patellar luxation and to determine risk factors associated with these complications.

Authors: Yarnall BW, Chamberlain CS, Hao Z, Muir P

OBJECTIVE: To determine polarization of synovial macrophages during development of cruciate ligament rupture (CR) and determine whether differences in synovial macrophage polarization in CR, osteoarthritis (OA), and healthy joints exist.

STUDY DESIGN: Prospective case-controlled study.

ANIMALS: Client-owned dogs with unstable stifles with CR (n = 22), paired stable contralateral stifles with partial CR (pCR; n = 7), joints with OA not related to CR (n = 6), and clinically normal (Normal; n = 7) joints.

Authors: Lee SJ, Frederick SW, Cross AR.

OBJECTIVE: To report the use and long-term outcome of dogs with surgical site infection (SSI) after tibial plateau leveling osteotomy (TPO), treated with an amikacin-infused collagen sponge and implant removal.

Authors: Ferrell CL, Barnhart MD, Herman E

OBJECTIVE: To report infection rate, implant removal rate, and postoperative antibiotic therapy after tibial tuberosity advancement (TTA) in dogs.

STUDY DESIGN: Retrospective study.

ANIMALS: One thousand seven hundred sixty-eight stifles in 1,732 dogs.

Authors: Giangarra JE, Lanz OI, Glennon JC, Kobayashi T, Tarkanian M, Tepic S, Werre SR.

OBJECTIVES: The aim of this study was to compare the strength of three described techniques for repair of the medial crural fascia to the strength of the intact fascia of the paired limbs.

PRACTICAL RELEVANCE: Traumatic stifle joint luxation is an uncommon but severe injury. There is usually rupture of several stabilising structures of the joint including the cruciate ligaments, collateral ligaments, joint capsule and menisci. Successful management of this condition requires good anatomical knowledge and repair or replacement of all damaged structures to achieve adequate joint reduction and stability. Better understanding of the treatment options available will aid clinical decision-making.

OBJECTIVE: To measure the density of cellular phenotypes in canine caudal cruciate ligament (CaCL), cranial cruciate ligament (CrCL), medial collateral ligament (MCL), and long digital extensor tendon (LDET).

STUDY DESIGN: Ex-vivo study.

METHODS: Ten CaCL, CrCL, MCL, and LDET obtained from 1 stifle of 10 dogs with no gross pathology were analyzed histologically. The density of cells with 3 nuclear phenotypes (fusiform, ovoid, and spheroid) was determined within the core region of each specimen.

OBJECTIVE: To evaluate recovery of limb function by use of gait force analysis after tibial plateau leveling osteotomy (TPLO) in dogs with unilateral cranial cruciate ligament (CrCL) rupture.

ANIMALS: 19 dogs with unilateral CrCL rupture treated with TPLO.

Measurement of fore and pelvic limb alignment in veterinary orthopedics is significant, as it is in human medicine. The establishment of reference ranges for alignments and comparing measured ranges in diseased animals to these reference values would allow veterinarians to specify the quantitative degree of an angular deformity, plan suitable treatments and evaluate treatment outcomes. Patellar luxation is a common orthopedic disease in small animal clinics.
