OBJECTIVE: To evaluate the influence of osteoarthritis on the measurement of patella tendon angle (PTA) and determine intraobserver and interobserver variability.

STUDY DESIGN: Retrospective clinical study.

SAMPLE POPULATION: Eighty-seven mediolateral radiographs that were obtained prior to tibial tuberosity advancement.

Category: Knee - Osteoarthritis

OBJECTIVE: To determine the discrepancy between true distance of tibial tuberosity advancement (tTTA) and the most commonly used cages. The null hypothesis was that tTTA would be within 1.5 mm difference of the cage size.

Category: Knee

OBJECTIVE To determine whether medial patellar luxation would affect radiographic tibial plateau angle (TPA) measurements in small-breed dogs. DESIGN Prospective cross-sectional study.

Category: Knee

OBJECTIVE To determine rate of and factors associated with return to agility competition for dogs with cranial cruciate ligament (CrCL) rupture treated with tibial plateau leveling osteotomy (TPLO). DESIGN Retrospective case series with nested case-control study.

OBJECTIVE: To evaluate safety and accuracy of lateral pin placement for the use of a Leipzig stifle distractor (LSD) and to assess improvements in visualization and treatment of the lateral meniscus in the canine stifle.

Category: Arthroscopy - Knee

OBJECTIVE: To compare the use of stainless steel staples with absorbable staples for closure of skin incisions in dogs undergoing tibial plateau leveling osteotomy (TPLO).

STUDY DESIGN: Prospective study.

SAMPLE POPULATION: Client-owned dogs (n = 80).

Category: Knee

BACKGROUND: Patella alta is the proximal displacement of the patella within the femoral trochlea. Previous studies have identified an association between patella alta and patella luxation. Distalisation of the tibial tuberosity has been recommended to establish proximodistal alignment of the stifle extensor mechanism with the underlying femur in dogs affected by patella alta. However, a recent canine ex vivo study found stifle extensor mechanism load increased significantly following tibial tuberosity distalisation.

OBJECTIVES: To compare the short-term complications of unilateral versus single-session bilateral medial patellar luxation surgery in small dogs.

Category: Knee

OBJECTIVE: To identify possible biomechanical causes for the predominantly unilateral presentation of cranial cruciate ligament (CCL) insufficiency by comparing the computed tomographic (CT) features of the tibial plateau of CCL affected and contralateral sound stifles in dogs with unilateral CCL insufficiency.

STUDY DESIGN: Cross-sectional study.

OBJECTIVE: To determine the influence of a 7-day course of postoperative antibiotherapy (cefpodoxime) on surgical site infections (SSI) after tibial plateau leveling osteotomy (TPLO).

STUDY DESIGN: Prospective, randomized, double-blinded, placebo-controlled clinical study.
