Yes, dogs often still exhibit a positive cranial drawer sign after a Tibial Plateau Leveling Osteotomy (TPLO), even though the surgery is highly successful. While TPLO eliminates the abnormal "tibial thrust" (sliding) during walking, it does not replace the torn ligament, meaning the joint may still have laxity during a manual exam.

Will a dog still have cranial drawer after TPLO?

Although it is considered that tibial cranial drawer signs (TCDS) do not disappear with tibial plateau leveling osteotomy (TPLO), in some cases, this may occur and is presumed to be due to periarticular fibrosis; however to our knowledge, no reports have confirmed the disappearance of TCDS after TPLO.

What is the most common complication of TPLO?

Incisional problems were the most frequently reported minor complication (47 cases); they included seroma formation, inflammation, bruising, premature suture removal, and excessive skin trauma caused by licking.

How to know if dog ruined TPLO surgery?

Persistent Lameness or Limping

Mild lameness is expected for the first few weeks after TPLO surgery. Most dogs show significant improvement within 8–12 weeks. However, if limping persists beyond this period or worsens, it may signal poor bone healing, implant failure, or an underlying infection.

What does a positive cranial drawer mean?

The ability to move the tibia forward (cranially) with respect to a fixed femur is a positive cranial drawer sign indicative of a CCL rupture.

Diagnosing Cruciate Failure in Dogs - Manual Tests

Would my dog be able to walk if he tore his ACL?

If your dog's cruciate becomes injured or torn, your dog's knee will become unstable, reducing your pup's ability to run and walk normally and causing pain.

Can a dog reinjure after TPLO?

Can my dog re-tear the cruciate ligament after surgery? No. Since we are not replacing the CCL, it cannot be torn. Likewise, once complete healing is obtained (about 6 months), the implants are not at much risk of breaking or moving.

What does TPLO failure look like?

Signs of implant failure may range from non-existent (single screw breaking) to an acute onset of pain and lameness in the operated limb. Infection may occur in approximately 5% of patients following a TPLO procedure.

Is TPLO a permanent fix?

Long-Term Success. Most dogs that undergo TPLO surgery experience a full return to their normal activity levels. Unlike other repair techniques, TPLO provides a permanent solution without reliance on artificial ligament replacements, that have a higher risk of failure and other complications.

Can a dog have TPLO surgery twice?

The incidence of needing repeat surgery on the same leg that has had a TPLO is very low. The main causes for this would include a post liminary meniscal injury (2-8%), implant-associated infection requiring removal of the implants (<2%), or implant breakage requiring addition stabilization.

How often does TPLO fail?

For 90–95% of dogs, TPLO implants stay intact and functional for life. The titanium or stainless steel plates are biocompatible and rarely cause problems. However, implant failure happens in 5–10% of cases, often due to: Screw loosening from too much activity or poor bone healing.

Can TPLO screws come loose?

In a small number of dogs, the screws that hold the bone in its new position can become loose over time. If this happens, excessive movement of the bone segments against one another can delay healing and, in the worst-case scenario, the screws or plate can break and require replacement.

Can dogs climb stairs after TPLO surgery?

No Stairs

Stairs should be limited to a short flight for the first 2 - 4 weeks following surgery. Longer flights of stairs should not be used for strength training your dog's knee after surgery, but they are permitted with supervision after 4 weeks post-surgery.

What is a pivot shift after TPLO surgery?

Pivot Shift:

Abnormal rotational instability after TPLO. Creates a strange gait due to the rotation of the tibia inward when weight-bearing. Rare and poorly understood. Can occur intraoperatively or post-operatively and require a secondary procedure to stabilize.

How long does it take for the bone to heal after TPLO surgery?

Recovery following the TPLO Surgery is relatively short. It takes about 8 weeks for the bone to heal and an additional 8 weeks (for a total of 16 weeks) before the pet can resume regular, unrestricted activity.

What is the success rate of TPLO surgery in dogs?

The success rate for TPLO surgery is very high-between 90% and 95%. Compared to any other procedure, dogs who undergo TPLO surgery recover more quickly and get back on all four feet sooner. With TPLO surgery and proper rehabilitation, your dog will be able to recover completely from a CCL tear and regain full mobility.

Can a dog tear their meniscus after TPLO surgery?

Complications after TPLO surgery are uncommon, but no surgery is risk-free. Potential problems include infection, inflammation of the tendon between the kneecap and the tibia, bone fracture, and tearing of the meniscus.

What are the symptoms of TPLO plate rejection?

Understanding TPLO Plate Rejection Symptoms:

Swelling and Inflammation: One of the earliest signs of TPLO plate rejection is localized swelling and inflammation around the surgical site. This may occur shortly after surgery or even months later. Monitoring the incision area for abnormal swelling is crucial.

What are the odds of reinjury after ACL surgery?

Investigators have reported reinjury rates following ACL surgery to range as high as 30-39%. This rate of reinjury results in as many as 4 in every 10 surgeries being attributed to reinjury. This level of reinjury following ACL surgery is unacceptable.

Do dog ACL tears heal?

You may also wonder, will a torn ACL heal on its own? Unfortunately, no. Once torn, the ligament will not heal like skin or bone. Your dog will need treatment to stabilize the leg so they can walk effectively without injuring the other limbs that are now carrying more weight.

What breeds are prone to ACL tears?

The dog breeds on the following list are some of the most prone to ACL tears:

• Bichon Frises — This breed's playful demeanor can lead to a luxating patella, also known as a slipped kneecap. ...
• German Shepards — These dogs are very active, have large frames, and are prone to hip dysplasia.

What if my dog jumps after ACL surgery?

Your dog should not be allowed to run or jump after TPLO surgery until the knee has had adequate time to heal. Typically, dogs can return to full physical activity approximately 6 months after TPLO surgery. If your dog jumped after TPLO surgery, contact your vet to discuss whether an examination is recommended.
