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).

This retrospective observational study aimed to characterize the severity and distribution of OA in the stifle joints of small and medium dogs with CCL injury and/or MPL.

Radiographs of the stifle joints from 218 dogs from 10 small and medium breeds were included; 127 joints had CCL injury, 76 joints had MPL, and 73 joints had CCL injury and MPL. OA was graded at 33 sites within the joint.

Surgical treatment of a superficial digital flexor tendon luxation is the treatment of choice, since nonsurgical treatment has been shown to be unsuccessful in dogs in which it has been attempted.

The objectives of this study were to report complications and short- to long-term outcomes in dogs with superficial digital flexor tendon luxation treated with abrasion calcaneoplasty, an adjunctive surgical technique, in addition to traditional repair.

Cranial cruciate ligament disease is a common pathological condition in dogs that is often presented in daily clinical practice.

Different risk factors for the development of this condition include breed, sex, age, bodyweight and neuter status, as well as different biological and biomechanical mechanisms. In the literature, special attention has been paid to the role of the tibial plateau angle in damage to the cranial cruciate ligament.

Background: Achilles mechanism rupture is a surgical condition involving primary tenorrhaphy with various described means of surgical augmentation and bolstering.

Aim: To report complications and outcomes with a novel Achilles repair technique in dogs using a superficial digital flexor tendon (SDFT) or deep digital flexor tendon (DDFT) allograft.

Objectives: To investigate whether a difference exists in incidence of medial meniscal tears between small (≤15 kg) and medium-to-large (>15 kg) dogs with naturally occurring cranial cruciate ligament disease.

OBJECTIVE To compare the biomechanical properties and gapping characteristics following loop modification of a 3-loop-pulley (3LP) pattern in an ex vivo canine common calcaneal tendon (CCT) avulsion repair model.

SAMPLE 56 skeletally mature hindlimbs from 28 canine cadavers.

Objective: The aim of this study was to describe the arthroscopic changes to the caudal cruciate ligament (CdCL) in dogs with cranial cruciate ligament disease.
