  • Anterior (Cranial) Cruciate Ligament Rupture
    Cranial Cruciate Ligament Rupture in Dogs The cruciate ligaments are tough fibrous bands that connect the distal femur (thigh bone) to the proximal tibia (shin bone). Two cruciate ligaments, the cranial (anterior) and the posterior cruciate ligaments, are found in the knee joint of dogs and cats (and most other domestic animals). These ligaments work like a hinge joint in the knee and are responsible for providing anterior-posterior stability to the knee joint. Normal Knee Joint of a Dog Rupture of the cranial cruciate ligament is rare in cats. It occurs frequently in overweight, middle- and older-aged dogs. Certain dog breeds appear to be predisposed to cranial cruciate ligament rupture. Most commonly, the cocker spaniel and rottweiler are affected. The miniature and toy poodle, Lhasa apso, bichon frise, golden retriever, Labrador retriever, German shepherd and mastiff seem to be predisposed as well. The normal knee joint works as a hinge, keeping the knee stable as it bends. Tearing of the cranial cruciate ligament causes instability of the knee joint and it ceases to function properly. Most cranial cruciate ligament tears in dogs occur gradually, resulting in a low-level lameness that may or nay not improve over time. After the ligament tears, inflammation occurs within the joint. Continued use and weight bearing by the dog often causes the ligament to rupture completely. Dogs that rupture one cruciate ligament have about a fifty percent chance of rupturing the other. Normal Knee Joint of a Dog Rupture of the cranial cruciate ligament in dogs can also occur acutely. Similar to cranial cruciate ligament rupture in humans, resulting from athletic injuries to the knee, dogs can tear this ligament by jumping up to catch a ball or Frisbee or by jumping out of a truck or off a porch.

Galloway, D.V.M Teresa Millar, D.V.M 7020 Francis Road, Suite 100 Richmond, BC V6Y 1A2 (604) 274-9938 www.stevestonvethospital.com CRANIAL CRUCIATE LIGAMENT RUPTURE Anatomy There are two cruciate ligaments in the canine stifle (knee) joint, the cranial and the caudal ligaments. In human knees, they are known as the ACL and PCL. The cranial cruciate ligament is the one most commonly injured in dogs resulting in discomfort and stifle instability with subsequent arthritis. Two cartilage pads called menisci are found within each knee. Femur FEMUR Patella Fabella CCL Meniscus Lateral Patellar Ligament Collateral Ligament Tibial Slope Tibia Photo credit: dfwvetsurgeons.com Why did the ligament rupture? We do not fully understand the cause of cranial cruciate ligament rupture in dogs but we do know that most cases are a result of slowly progressive cranial cruciate ligament (CrCL) degeneration. A genetic cause is being researched and there is considerable support for this belief. Once weakened, the ligament can then rupture with minimal trauma. Dogs that rupture the cruciate ligament in one stifle are at an increased risk of rupturing the ligament in the other stifle (at least a 50% chance). © 2015 – Steveston Veterinary Hospital Clinical Signs Lameness is the most common symptom seen with CrCL rupture and can range from mild intermittent lameness with mild partial ligament tears to non-weight bearing lameness with complete tears and co-existent meniscal damage. Diagnosis The CrCL rupture is diagnosed by palpation (feeling the knee) and eliciting drawer motion or laxity within the joint. Dogs with mild ligament tears and those who are very tense may require sedation.

Robbins,z BA, Lars Engebretsen,§ MD, PhD, and Robert F. LaPrade,*k MD, PhD Investigation performed at Steadman Philippon Research Institute, Vail, Colorado, USA Background: Meniscal ramp lesions have been defined as a tear of the peripheral attachment of the posterior horn of the medial meniscus (PHMM) at the meniscocapsular junction or an injury to the meniscotibial attachment. Precise anatomic descriptions of these structures are limited in the current literature. Purpose: To quantitatively and qualitatively describe the PHMM and posteromedial capsule anatomy pertaining to the location of a meniscal ramp lesion with reference to surgically relevant landmarks. Study Design: Descriptive laboratory study. Methods: Fourteen male nonpaired fresh-frozen cadavers were used. The locations of the posteromedial meniscocapsular and meniscotibial attachments were identified. Measurements to surgically relevant landmarks were performed with a coordinate measuring system. To further analyze the posteromedial meniscocapsular and meniscotibial attachments, hematoxylin and eosin and alcian blue staining were conducted on a separate sample of 10 nonpaired specimens. Results: The posterior meniscocapsular attachment had a mean 6 SD length of 20.2 6 6.0 mm and attached posteroinferiorly to the PHMM at a mean depth of 36.4% of the total posterior meniscal height. The posterior meniscotibial ligament attached on the PHMM 16.5 mm posterior and 7.7 mm medial to the center of the posterior medial meniscal root attachment.

    Posterior Cruciate Ligament Injuries - OrthoInfo - AAOS 6/14/19, 11:19 AM DISEASES & CONDITIONS Posterior Cruciate Ligament Injuries The posterior cruciate ligament is located in the back of the knee. It is one of several ligaments that connect the femur (thighbone) to the tibia (shinbone). The posterior cruciate ligament keeps the tibia from moving backwards too far. An injury to the posterior cruciate ligament requires a powerful force. A common cause of injury is a bent knee hitting a dashboard in a car accident or a football player falling on a knee that is bent. Anatomy Two bones meet to form your knee joint: your thighbone (femur) and shinbone (tibia). Your kneecap sits in front of the joint to provide some protection. Bones are connected to other bones by ligaments. There are four primary ligaments in your knee. They act like strong ropes to hold the bones together and keep your knee stable. Collateral ligaments. These are found on the sides of your knee. The medial collateral ligament is on the inside and the lateral collateral ligament is on the outside. They control the sideways motion of your knee and brace it against unusual movement. Cruciate ligaments. These are found inside your knee joint. They cross each other to form an "X" with the anterior cruciate ligament in front and the posterior cruciate ligament in back. The cruciate ligaments control the back and forth motion of your knee. https://orthoinfo.aaos.org/en/diseases--conditions/posterior-cruciate-ligament-injuries/ Page 1 of 6 Posterior Cruciate Ligament Injuries - OrthoInfo - AAOS 6/14/19, 11:19 AM Normal knee anatomy.

    KNEE FLEXION Did you know that taking a step forward uses around 200 muscles? One muscle action that plays a central role in walking and running is knee flexion. Let’s take a look at this muscle action and all of the individual muscles used. Download Human Anatomy Atlas to learn about more muscle actions. KNEE CAP KNEE MCL ACL OVERVIEW The knee is one of the largest joints in the human body. It provides shock absorption during walking and running, and allows flexion and extension. The knee’s stability is maintained MEDIAL by different ligaments like the MENISCUS anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament LCL PCL LATERAL MENISCUS (MCL), medial meniscus, lateral meniscus, lateral collateral ligament (LCL). ANTERIOR VIEW POSTERIOR VIEW KNEE EXTENSION KNEE FLEXION KNEE FLEXION OVERVIEW Knee flexion is the action of the knee bending the leg towards the buttock.
