A hot day so we had the air con on all day. Mal went watering at the allotment. I watched tennis.
In the evening the vet rang to tell us Ellie has a ruptured knee capsule, yes, seems the same as the cruciate ligament problem we thought. Nowadays they put a plate in……..
The Injury: More Than Just a “Knee Capsule” Rupture
While you were told your dog has a “ruptured knee capsule,” this is often a general term used to describe a more specific and very common injury in dogs: a rupture of the Cranial Cruciate Ligament (CCL). The CCL is the equivalent of the Anterior Cruciate Ligament (ACL) in humans and is a critical stabilizer of the knee joint, which veterinarians call the stifle.
Imagine the knee as a hinge connecting the femur (thigh bone) and the tibia (shin bone). The CCL acts like a strong rope within this hinge, preventing the tibia from sliding forward out of place when your dog walks, runs, or jumps.
A rupture can happen suddenly due to trauma, but more often it’s the result of a slow, degenerative process where the ligament gradually weakens over time, much like a fraying rope. This underlying degeneration is why many dogs who rupture one CCL will eventually have problems with the other knee.
When the CCL tears, the knee becomes unstable. This instability is what causes the pain, lameness, and inflammation you’ve likely observed in your dog. The “popping” sound that is sometimes heard is often the result of damage to the meniscus, a cartilage pad within the knee that can get crushed once the joint is unstable.
The Surgery: Likely a Tibial Plateau Leveling Osteotomy (TPLO)
The mention of a “plate” strongly suggests that your dog is undergoing a sophisticated and highly effective surgical procedure, most likely a Tibial Plateau Leveling Osteotomy (TPLO). Another similar, but less common, procedure is the Tibial Tuberosity Advancement (TTA).
The goal of a TPLO is not to repair the torn ligament itself, as it has a poor blood supply and doesn’t heal well. Instead, the surgery aims to change the biomechanics of the knee joint so that the CCL is no longer necessary for stability.
The vet feels sure Ellie is up to all of this as otherwise she is fit and healthy. The ortho surgeon has performed this operation many times. He is on holiday at the moment but they will let us know when he can schedule this in.
And it continues…….
The recovery from TPLO surgery is a marathon, not a sprint, and your role is vital to a successful outcome. Here is a general timeline, though your veterinarian will provide specific instructions for your dog:
- The First Two Weeks (Strict Confinement): This is the most critical period. Your dog’s activity must be severely restricted to allow the initial healing of the incision and the bone. This typically means confinement to a crate or a small room with no access to stairs or slippery surfaces. Short, controlled leash walks for toileting purposes only are usually permitted. You will also be managing pain medication and monitoring the incision site.
- Weeks Two to Eight (Gradual Increase in Activity): After a follow-up visit and potentially X-rays to check on healing, your veterinarian will likely prescribe a gradual increase in controlled leash walks. The walks will be short and slow to encourage gentle weight-bearing, which helps with muscle maintenance and bone healing. Running, jumping, and rough play are still strictly forbidden.
- Weeks Eight to Twelve (Building Strength): If X-rays confirm good bone healing, a more structured rehabilitation plan may begin. This could include longer leash walks, gentle inclines, and potentially hydrotherapy (water treadmill) to build muscle mass without stressing the joint.
- After Twelve Weeks (Return to Normal): By this point, most dogs are well on their way to a full recovery. Your veterinarian will guide you on when it is safe to gradually reintroduce off-leash activities. Full recovery and return to normal athletic function can take up to six months
