What happens if I don’t do surgery?
Since the knee is unstable without an intact cruciate ligament, the wearing between bone and cartilage becomes abnormal and the joint begins to develop irreversible degenerative changes. Pain and lameness persist, and the opposite leg becomes stressed. Please contact your veterinarian or come in for a consultation to find out the options for your dog.
Tibial Plateau Leveling Osteotomy (TPLO) is often the best option for active, large dogs. TPLO changes the biomechanical function of the knee joint to stabilize the cruciate deficient stifle joint. After exploring the joint, removing damaged ligament fragments and any torn portions of the meniscal cartilage and smoothing bone spurs, the tibial plateau is rotated to a more level position, almost eliminating the need for a cranial cruciate ligament. It provides the best long term function and can stop arthritic, degenerative changes over time. It is an involved surgery since the bone must be precisely cut, rotated, and stabilized with a bone plate and screw.
Extracapsular Repair is a techinically simpler procedure than TPLO to treat a cruciate rupture. As in the TPLO surgery, the damaged cruciate ligament is removed, any damaged portions of the meniscal cartilage is removed and any bone spurs are smoothed. A strong suture is then passed around the stifle joint to provide stability while the stifle heals. Depending on several factors, this option may be sufficient for your pet, although arthritic changes do continue to progress over time and the strong suture does loosen somewhat eventually.
Rehabilitation after surgery is very important in helping your dog recover better after surgery. Your dog will be restricted to leash only and minimal activity for 8 to 12 weeks, with slowly building up activity after that. We recommend our patients go through a 6-treatment therapeutic laser series that helps speed healing and reduce swelling after the surgery. Your pet will receive 2 laser treatments after the surgery itself, one right after the surgery before they wake up from anesthesia and then the morning after surgery, having stayed in hospital overnight.
