Ruptures and partial tears to one or both Cranial Cruciate Ligaments (CCL) is a remarkably common injury in our doggy friends. While certain breeds seem to have significantly more frequency of injury, I see it pop up in a wide variety of breeds, ages and sizes of dogs.
Traditionally, it has been believed that typically only small dogs, under about 15kg, fare just as well with conservative management as they do with surgical repair options. At significantly less cost also. This belief is based on a study which showed very positive outcomes for the small dogs and not so much resolution of lameness in the bigger dogs. Some practitioners, however, have been questioning the assumptions since.
Dr Narda Robinson DVM is one practitioner who has been quite vocal about the lack of options many pet owners are given when faced with a CCL injury. She has compiled some good evidence here to endeavour to debunk many commonly held beliefs around why surgery should be the primary go-to option for sorting out our dogs dodgy knees.
So, when an owner makes the decision to give the surgical option a miss, at least on a trial basis, what is the conservative option?
- The first step is to ensure the dog is a healthy weight or slightly underweight to help reduce the loading on the stifle joint. Being overweight is one of the biggest and most manageable risk factors noted to contribute to CCL damage.
- Next, keeping your dog’s activity controlled. Complete crate rest was once advised however studies have shown it to be not necessary. Rest and avoiding jumping up and down from vehicles, beds etc; minimising risk of slipping on smooth floors, and going for frequent short controlled leash walks is the ideal for 6-8 weeks.
- Finally, the use of anti-inflammatory or analgesic medication as required.
From an osteopathic perspective it is possible to boost the effects of this conservative management firstly by recognising that it is, in most cases where the lameness has developed gradually and insideously, strongly likely that biomechanical restrictions in the dogs body have contributed to asymmetrical weight bearing through the hind legs and the stifle joint. This asymmetry and dysfunction can be addressed using Osteopathic techniques which are gentle and often pain free. By allowing the dog’s body, especially the lumbar and pelvic regions to function to the best of their ability, it is possible to minimise overloading of individual joints and enhance circulatory and nervous flow to the joints and tissues and hence allow the body to do it’s best healing work.
One of the big risks of CCL damage is that around 50% of dogs will present with damage to the other CCL within 6 months of surgery to repair injury to the first. This suggests two possibilities. Firstly, the obvious one that during recovery, the ‘good’ knee will be taking more than its fair share of workload, and secondly, that there is some underlying biomechanical factors that haven’t been addressed in the first instance which are continuing to throw excess loading into the joints. Whether post-surgery, or opting for the conservative option, it is therefore crucial to ensure the dog’s body is actually able to work symmetrically, as well as to then formulate a thorough rehabilitation plan to help ensure the dog begins to use themselves evenly. This rehab can begin within the first few weeks post-surgery or during the rest period if managing conservatively.
Allied therapies including dietary changes (examples here and here) and nutritional supplementation and herbs, hydrotherapy, acupuncture, laser, orthoses, stem cell therapy and cryotherapy are some of the many that may be useful within the management plan for CCL rehabilitation.
From a preventative point of view, again it is crucial to ensure dogs are able to use themselves as symmetrically as possible. This can be achieved by osteopathic preventative/maintenance visits from a young age, to thoroughly examine and uncover any dysfunctional regions of the body and remove these restrictions before they begin to significantly alter the way the dog is moving. Ensuring that dogs are given consistent, relatively controlled activity allows them to develop strong and healthy musculoskeletal systems – so avoid the weekend warrior approach of relatively little or no exercise during the week followed by manic ball chasing or frisbee catching at the weekend. Make exercise a big part of your daily routine so your dog has a good baseline level of fitness and strength to help cope with the inevitable extra fun at the weekends or on holidays. Also, make sure nails are kept trimmed regularly, both to avoid slipping risk and also to help avoid changes in limb posture which may occur if the dog is feeling discomfort during activity from overly long nails.
