Understanding CCL disease
The cranial cruciate ligament (CCL) stabilizes your dog’s knee by preventing the tibia from sliding forward beneath the femur during weight-bearing. When it becomes stretched, partially torn, or completely ruptured, the knee becomes unstable, painful, and prone to rapidly progressing arthritis.
Most owners assume the knee was injured during a run or jump. In reality, most dogs develop CCL disease gradually — the ligament weakens over months or years due to degeneration, breed predisposition, excess body weight, poor conditioning, or chronic joint inflammation. Often, a seemingly minor event is simply the final straw.
Don’t wait on these symptoms. Joint damage — and arthritis — accelerate with every step on an unstable knee. Same-day evaluations available: (703) 378-9791
Signs your dog may have a CCL injury
Diagnosis
Diagnosis combines a thorough physical examination with radiographs. Together, these give us the information needed to understand the extent of the injury, the degree of arthritis already present, and the most appropriate treatment path.
Physical Examination
Radiographs (X-rays)
Note on tibial plateau angle: Dogs with angles above 30° are generally better candidates for TPLO regardless of size. Dr. Masood measures this on every patient before making any treatment recommendation.
Often present alongside CCL rupture
Approximately half of dogs with a complete CCL rupture also have a concurrent injury to the medial meniscus — the C-shaped cartilage that acts as a shock absorber inside the knee. Meniscal tears are painful and, if unaddressed, can cause ongoing lameness even after successful CCL repair.
Meniscal damage is assessed and addressed at the time of CCL repair when present. Your dog will not need a second procedure.
Signs that may suggest meniscal involvement
Treatment options
There is no single right answer for every dog. The appropriate treatment depends on your dog’s size, tibial plateau angle, activity level, overall health, and your goals. Dr. Masood will give you a genuine recommendation — not a default.

Surgical technique — in detail
The science backs this up. Lateral suture has been performed for over 30 years and, in the words of a board-certified veterinary surgeon published in dvm360, is “quick, affordable, and safe.”
The research
TPLO has become the default recommendation in many practices, particularly for larger dogs. But a complete reading of the peer-reviewed literature tells a more nuanced story — and pet owners deserve to see it.
TPLO is aggressively marketed as the superior surgery — especially for larger dogs. Many pet owners are told it is simply “better” without being shown the evidence. A thorough reading of the peer-reviewed literature tells a very different story. At no published time point up to 4.6 years of follow-up does TPLO demonstrate superior outcomes to lateral suture — and the most recent long-term study shows lateral suture patients actually fared better. Here is the evidence, study by study.
At 6 months & 2 years
No significant difference between LSS and TPLO.
Multiple peer-reviewed studies find no statistically significant difference in limb function between lateral suture and TPLO at 6 months and 2 years. Equivalent outcomes — at a fraction of the cost, invasiveness, and complication risk.
Conzemius et al., JAVMA 2005 · Au et al., Vet Surg 2010
At 4.6 years — most recent long-term data
Lateral suture patients fared significantly better.
TPLO patients had a significantly higher risk of stiffness (IRR 1.33) and lameness (IRR 1.34) vs. lateral suture patients at 4.6 years. This is the most current long-term published evidence — and TPLO patients were worse off.
Engdahl et al., Veterinary Record 2023
In large dogs 55–88 lb
Lateral suture restores near-normal joint mechanics — even in large breeds.
3D kinematic analysis found lateral suture restored joint movement largely comparable to a healthy stifle across multiple planes of motion in dogs the size of German Shepherds and Pit Bulls. The argument that LSS does not work in larger dogs is not supported by this data.
Del Carpio et al., PLoS ONE 2021
“TPLO is certainly not markedly superior in clinical outcome to the less expensive, less risky, and more easily performed LSS.”

After surgery
The surgery stabilizes the knee. What happens over the following 8–12 weeks determines how well your dog heals for the rest of their life. We structure every step and coordinate everything through one practice.
Strict rest — no running, jumping, or stairs. Toe-touching or partial weight-bearing begins. Monitor the incision daily for swelling or discharge. Use an Elizabethan collar if licking. Prescribed pain management as directed.
Short controlled leash walks only — 5 to 10 minutes, 3 to 4 times daily. No off-leash activity. Begin gentle physical therapy exercises if directed. Strict activity restriction is the most important factor protecting the repair during this window.
Most owners see clear improvement in comfort and limb use. Walk duration increases progressively. The loading phase of the joint support protocol is complete — transition to long-term maintenance as prescribed. Muscle rebuilding begins in the affected leg.
Most dogs at or near full function. Recheck confirms healing before off-leash activity is cleared. Periarticular fibrosis is now mature — the scar tissue has become the permanent stabilizer.
Most patients return to normal family activities. Prescribed joint support continues for long-term protection as directed. Weight management and muscle conditioning remain important — particularly given the 40–60% lifetime risk of the opposite knee rupturing.
Weight management matters. Even a small amount of excess weight significantly increases stress on the healing knee and accelerates arthritis. We’ll give you specific guidance on lean body condition throughout recovery.
Long-term joint support
Surgery is the beginning, not the end. What happens in the months and years after the procedure determines how comfortably your dog lives for the rest of their life. Every patient leaves with a written post-operative plan — not a generic handout, but a protocol built around that specific dog’s age, weight, activity level, and the degree of arthritis already present at the time of surgery.
Dr. Masood prescribes joint support on a case-by-case basis. This may include injectable disease-modifying agents, oral joint supplements, anti-inflammatory medication as clinically indicated, and a structured return-to-activity program. The approach is adjusted at every recheck based on how the patient is responding. The goal is simple: maximum long-term comfort with minimum long-term medication.
We do not apply a one-size-fits-all supplement protocol. What Dr. Masood recommends depends on the dog’s age, the degree of existing arthritis, and how the recovery is progressing. Every recommendation is explained at discharge and reviewed at each recheck.
Even modest weight reduction dramatically reduces mechanical stress on the healing joint and slows arthritis progression. We provide specific guidance — not a general suggestion — based on your dog’s current condition.
This is not a surgery-and-discharge practice. Dr. Masood sees every patient at every recheck and remains available between visits. If something changes, we adjust the plan. That continuity of care is one of the things that separates outcomes over time.
Prognosis & future risk
With appropriate surgical treatment and rehabilitation, most dogs return to a comfortable, active lifestyle. Arthritis cannot be completely eliminated — some degree of wear has already occurred — but it can be managed effectively and slowed significantly with the right long-term support plan.
With appropriate surgery and structured recovery, the large majority of dogs return to their normal daily activities — walking, running, playing — without significant lameness.
Surgery stops progression. Prescribed joint support, long-term monitoring, and weight management keep most dogs comfortable without daily pain medication.
The sooner the joint is stabilized after rupture, the less arthritis accumulates. Dogs treated promptly consistently do better at long-term follow-up.
Dogs that rupture one CCL have a 40–60% lifetime risk of rupturing the other. We plan for this from day one: weight management, conditioning, prescribed joint support, and monitoring the opposite limb are all part of the program. If the second knee ruptures, you won’t be starting from zero. You’ll already have a relationship with the same surgeon, the same post-op program, and a full record of your dog’s case.
Joint damage progresses with every step on an unstable knee. The sooner the joint is stabilized, the better the long-term outcome. Schedule an evaluation — your consultation fee applies toward surgery if you proceed with us.
