Types of ACL Surgery in Dogs

Introduction

Overview of ACL tears in dogs and the need for surgery

ACL tears are a common injury in dogs, especially in certain breeds and active dogs. The cranial cruciate ligament, also known as the anterior cruciate ligament (ACL) in humans, connects the upper and lower leg bones at the dog’s knee. When this ligament becomes injured or torn, it can cause significant pain and lameness in the affected leg. Surgery is often recommended to repair a dog’s torn ACL and restore normal joint function. However, there are alternative options to consider depending on the dog’s age, overall health, and the severity of the tear. These alternatives may be more suitable in certain cases where traditional surgery is not feasible or desired.

Alternatives to Dog ACL or Dog Cruciate Surgery

When considering alternatives to dog ACL or dog cruciate surgery, there are several options to explore: 1. Conservative Management:
  • This approach involves managing the dog’s condition without surgery and focusing on pain management, physical therapy, and weight management.
  • It may be suitable for dogs with partial ACL tears or those who may not be good candidates for surgery due to age, health conditions, or financial constraints.
2. Stem Cell Therapy:
  • Stem cell therapy involves using the dog’s own stem cells to promote healing and reduce inflammation in the affected area.
  • This can be a non-invasive option for dogs with partial ACL tears or those who cannot undergo surgery.
3. Platelet-Rich Plasma (PRP) Therapy:
  • PRP therapy utilizes the dog’s own blood platelets to stimulate healing and reduce inflammation.
  • This option may be beneficial for dogs with partial tears or as a complementary treatment alongside surgery.
4. Extracapsular Repair:
  • Extracapsular repair is a less invasive surgical option compared to traditional ACL surgery.
  • It involves using suture material to stabilize the knee joint and promote healing.
  • This procedure is best suited for smaller dogs or those with less severe ACL tears.
5. Tibial Plateau Leveling Osteotomy (TPLO):
  • TPLO is a more invasive surgical option that involves altering the alignment of the bones in the dog’s knee to reduce stress on the torn ACL.
  • This procedure is often recommended for larger dogs or those with more severe ACL tears.

Factors to Consider when Choosing the Right Surgery

When deciding on the most appropriate surgery for your dog’s ACL tear, it is important to consider the following factors: 1. Age of Your Dog:
  • Older dogs may not tolerate invasive surgeries well due to their age or underlying health conditions.
  • Less invasive options or conservative management may be more suitable in these cases.
2. Size and Breed of Your Dog:
  • Larger dogs may require more substantial surgical interventions to provide stability to the knee joint.
  • Smaller dogs may benefit from less invasive procedures or conservative management.
3. Severity of the ACL Tear:
  • The extent of the ACL tear will influence the type of surgery recommended.
  • Partial tears may be amenable to non-surgical treatment options, while complete tears often require surgical intervention.
4. Financial Considerations:
  • The cost of ACL surgery can vary depending on the type of procedure chosen.
  • Alternative options or conservative management may be more cost-effective for some dog owners.
5. Veterinary Recommendations:
  • Seek guidance from your veterinarian who will assess your dog’s specific condition and provide recommendations based on their expertise.
It is essential to discuss all available options with your veterinarian to determine the most appropriate course of action for your dog’s ACL tear.

Lateral Suture Technique

Explanation of the lateral suture technique for ACL surgery in dogs

The lateral suture technique, also known as extracapsular repair, is one of the three main surgery techniques used for treating dog ACL tears. This technique involves placing a strong suture material outside the joint to stabilize the knee and compensate for the torn ACL. During the surgery, the surgeon will make a small incision near the knee joint and identify the torn ACL. The suture material, commonly made of high-strength nylon or a similar material, is then passed through small tunnels drilled in the femur and tibia bones. The suture is tightly secured to hold the bones in place, allowing scar tissue to form and stabilize the knee joint. The lateral suture technique is less invasive compared to other surgical options such as TPLO (tibial plateau leveling osteotomy) and TTA (tibial tuberosity advancement). It is generally recommended for smaller and less active dogs, as well as dogs with a stable joint.

Pros and cons of the lateral suture technique

Like any surgical procedure, the lateral suture technique has its advantages and disadvantages. Here are some pros and cons to consider: Pros:
  • Less invasive: The lateral suture technique does not involve cutting or reshaping bones, making it a less invasive procedure compared to other options.
  • Cost-effective: This technique is generally more affordable compared to TPLO or TTA surgeries, which can be a deciding factor for some pet owners.
  • Suitable for certain patients: The lateral suture technique is often recommended for smaller or less active dogs with a stable joint, as it provides effective stabilization and allows scar tissue to form.
Cons:
  • Limited suitability: The lateral suture technique may not be suitable for dogs with certain conditions, such as severe joint instability or degenerative joint disease.
  • Potential for complications: While complications are relatively rare, there is a small risk of suture breakage or loosening over time, leading to a return of lameness.
  • Restricted activity during recovery: Dogs undergoing the lateral suture technique will typically require a period of restricted activity and rehabilitation to ensure proper healing.
It is important to consult with a veterinarian or a veterinary surgeon to determine the most appropriate surgical technique for your dog’s ACL tear. Factors such as the dog’s size, activity level, and overall joint health will be taken into consideration when making this decision.

Extracapsular Technique

Explanation of the extracapsular technique for ACL surgery in dogs

The extracapsular technique, also known as extracapsular repair, is one of the three main surgical techniques used for treating dog ACL tears. Similar to the lateral suture technique, this procedure aims to stabilize the knee joint by placing a strong suture material outside the joint. During the surgery, a small incision is made near the knee joint to access the torn ACL. The surgeon then uses a high-strength suture material, usually made of nylon or a similar material, to create a stabilizing loop around the knee joint. The suture is anchored to the femur and tibia bones, providing support and stability to the joint. Over time, scar tissue forms and helps stabilize the knee even further. The extracapsular technique is considered less invasive than procedures like TPLO or TTA, as it does not involve cutting or reshaping the bones. It is commonly recommended for smaller or less active dogs with a stable joint.

Pros and cons of the extracapsular technique

Pros:
  • Less invasive: The extracapsular technique does not require the cutting or reshaping of bones, making it a less invasive procedure than TPLO or TTA.
  • Cost-effective: Compared to other surgical options, the extracapsular technique is generally more affordable, which can be a deciding factor for some pet owners.
  • Suitable for certain patients: This technique is often recommended for smaller or less active dogs with a stable joint, as it provides effective stabilization and allows for the formation of scar tissue.
Cons:
  • Limited suitability: The extracapsular technique may not be suitable for dogs with severe joint instability or degenerative joint disease.
  • Potential for complications: While complications are relatively rare, there is a small risk of suture breakage or loosening over time, which can result in lameness recurrence.
  • Restricted activity during recovery: Dogs undergoing the extracapsular technique will typically require a period of restricted activity and rehabilitation to ensure proper healing.
It is crucial to consult with a veterinarian or veterinary surgeon to determine the most appropriate surgical technique for your dog’s ACL tear. Factors such as the dog’s size, activity level, and overall joint health will be taken into consideration when making this decision. The veterinarian will guide you through the benefits and risks of each technique to help you make an informed choice for your furry companion.

Tibial Plateau Leveling Osteotomy (TPLO)

Explanation of the TPLO technique for ACL surgery in dogs

The TPLO technique is another surgical option for dogs with torn ACLs. This procedure aims to reduce the amount of forward movement during the dog’s stride without the help of the ACL (CCL). It is often recommended for dogs with larger sizes or high activity levels, as well as those with a steep tibial plateau angle. During TPLO surgery, the surgeon will make an incision near the knee joint and access the tibia bone. The tibial plateau, which is the top section of the tibia, is then cut and repositioned to change the joint mechanics. A metal plate and screws are used to secure the repositioned bone in place, providing stability to the knee joint. The TPLO procedure is more complex and invasive compared to the lateral suture technique. It involves bone cutting and repositioning, which allows for a more direct stabilization of the knee joint. This technique addresses the issue of cranial tibial thrust, which is the forward sliding of the tibia bone that occurs when the ACL is torn.

Pros and cons of the TPLO technique

Pros:
  • Direct stabilization: The TPLO technique directly addresses the instability caused by a torn ACL by changing the joint mechanics, providing better stability compared to the lateral suture technique.
  • Suitable for larger dogs: The TPLO technique is often preferred for larger dogs or those with high activity levels, as it provides a more robust stabilization option.
  • Long-term success: Studies have shown good long-term success rates and improved biomechanics with the TPLO technique, especially in larger dogs.
Cons:
  • Invasive procedure: The TPLO surgery involves cutting and repositioning bones, which makes it a more invasive procedure with a potentially longer recovery period.
  • Higher cost: Due to the complexity of the procedure and the need for specialized equipment, the TPLO surgery is generally more expensive than the lateral suture technique.
  • Ongoing monitoring: Dogs undergoing TPLO surgery may require ongoing monitoring and potential plate removal if complications occur.
It is important to note that the most appropriate surgical technique for your dog’s torn ACL will depend on various factors, including their size, activity level, and overall joint health. Consulting with a veterinarian or veterinary surgeon is crucial to determine the best course of action for your dog.

Tibial Tuberosity Advancement (TTA)

Explanation of the TTA technique for ACL surgery in dogs

The TTA technique is another surgical option for dogs with torn ACLs. This procedure aims to alter the forces acting on the knee joint to reduce instability caused by the ACL tear. It is recommended for dogs with a steep tibial plateau angle and sufficient bone quality. During TTA surgery, the surgeon will make an incision near the knee joint and access the tibia bone. The tibial tuberosity, which is the bony prominence where the patellar tendon attaches, is then cut and repositioned. A titanium cage or spacer is used to stabilize the repositioned bone, altering the joint mechanics and reducing cranial tibial thrust. The TTA technique is a more recent innovation and is gaining popularity among veterinary surgeons. It provides a different approach to stabilizing the knee joint compared to the TPLO and lateral suture techniques.

Pros and cons of the TTA technique

Pros:
  • Alters joint forces: The TTA technique alters the forces acting on the knee joint to reduce instability caused by the torn ACL, providing effective stabilization.
  • Suitable for certain patients: Dogs with a steep tibial plateau angle and sufficient bone quality are typically good candidates for the TTA surgery.
  • Good long-term success: Studies have shown favorable long-term outcomes with the TTA technique, particularly in larger dogs.
Cons:
  • Invasive procedure: Like the TPLO surgery, the TTA surgery involves bone cutting and repositioning, which makes it a more invasive procedure compared to the lateral suture technique.
  • Higher cost: The complexity of the TTA surgery and the required specialized equipment contribute to its higher cost compared to the lateral suture technique.
  • Learning curve for surgeons: The TTA technique requires specialized training and experience for veterinary surgeons to perform accurately.
TPLO surgery for dogs
