ABSTRACT
Objective: To assess contact mechanics and 3-dimensional (3-D) joint alignment in cranial cruciate ligament (CCL)-deficient stifles before and after tibial plateau leveling osteotomy (TPLO) and tibial tuberosity advancement (TTA) with the stifle in 90° of flexion.
Study Design: In vitro biomechanical study.
Sample Population: Cadaveric pelvic limb pairs (n=8) from dogs weighing 28–35 kg.

ABSTRACT
Objective: To report topographic matching of selected donor sites and donor core sizes for congruous reconstruction of the weight-bearing aspect of the femoral condyles in dogs for autologous osteochondral transplantation (AOT) using computer simulation.
Study Design: Computer simulation.
Sample Population: Computed tomographic scans of the distal aspect of 1 femur from each of 6 mature dogs (>20 kg).

ABSTRACT
Objective: To design an experimental testing apparatus simulating a quasi-static model of the stance phase at a trot for a normal and a cranial cruciate ligament (CCL)-deficient stifle under near physiologic conditions.
Study Design: In vitro biomechanical study.
Animals: Paired pelvic limbs (n=6) from 3 dogs, weighing 29.5–31 kg.

ABSTRACT
Objective: To evaluate the sensitivity and specificity of low-field magnetic resonance imaging (lfMRI) for detection of meniscal tears in the canine stifle.
Study Design: Double-blinded prospective clinical study.
Animals: Forty-two consecutive stifles of dogs (≥20 kg; n=34) with clinical and radiologic signs suspicious for cranial cruciate ligament (CCL) insufficiency.

ABSTRACT
Objective: To measure matrix metalloproteinases (MMPs) suspected to be involved in the initiation or progression of osteoarthritis (OA) in cranial cruciate ligament (CCL) explant culture media using multiplex bead technology.
Study Design: In vitro experimental study.
Animals: Adult dogs with (n=10) and without (n=10) CCL deficiency.
