The standard grafts used for ACL reconstruction are tendon, either patellar tendon, hamstring, or quadriceps. However, the microstructure and composition of tendon differs from ligament. Ideally, the ACL would be replaced with the same tissue.

To evaluate the incorporation of a bone-ACL-bone graft (B-ACL-B) graft for ACL reconstruction, we performed a controlled laboratory study in a rabbit model with micro-computed tomography (μCT).

Objective: The aim of this study was to identify the ideal anchor point for patellar anti-rotational sutures for adjunctive stabilization of medial patellar luxation in both small and large breed dogs.

Objective: The aim of this study was to test the low sensitivity of the Allberg and Miles index to the stifle opening angle, evaluate the displacement of the patella after a Modified Maquet Technique using this index and assess the incidence of patellar luxation post-Modified Maquet Technique in dogs.

Objectives: Medial patellar luxation (MPL) is the most common developmental cause of hindlimb lameness in cats. The association between femoral and tibial conformation and MPL measured on computed tomography (CT) has not been reported in cats. The aims were to report femoral and tibial conformation in cats with and without MPL and to report normal femoral and tibial angles.

Objective: The aim of this study was to describe a novel limb-sparing technique for the management of feline bone neoplasia using a custom-made femoral endoprosthesis in combination with a total knee replacement (TKR) prosthesis.

Objective: To critically evaluate the evidence for rehabilitation interventions following surgery for cranial cruciate ligament disease (CCLD) in dogs.

Study design: Systematic review.

Objective: To describe the design principles and evolution, surgical technique, and outcome for custom constrained (uniaxial and rotating hinge) total knee replacement (TKR) in cats.

Study design: Retrospective case series.

Animals: Nine cats with traumatic stifle luxation (n = 8) or severe distal femoral deformity (n = 1) were considered suitable candidates.

Objective: The aim of this study was to compare the resulting short-term complications after simultaneous (SIM) or staged (ST) tibial plateau levelling osteotomy (TPLO) in patients that presented with bilaterally torn cranial cruciate ligaments.

Study design: This was a retrospective study.

Aseptic loosening of total knee arthroplasty continues to be a challenging clinical problem. The progression of the loosening process, from the initial well-fixed component, is not fully understood.

Although the goat is an established animal model in anterior cruciate ligament (ACL) research, in-vivo kinematics associated with ACL deficiency have not been previously described in this species.
