Canine Cranial Cruciate Ligament Injuries – Surgery or what??

How Cranial Cruciate Ligament Injuries can be managed when surgery isn’t the first choice.

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.

Hip Flexor for the rider – Part 2

So what exactly are these hip flexors we’ve been speaking of, and why are they so darn important to the horse rider??

The iliopsoas is one of the very important factors in achieving a symmetrical seat. I find if the hip flexors as a group are not working well through a full normal range of motion there will be huge struggles with trying to maintain even and effective seat and leg aids. There will also be knock on effects on the upper body and aids from there also.

As you can see below, they attach to the front of the spine and the inside of the pelvis before running down through the pelvis to attach onto the inner thigh. They act to draw the knee up towards the body, and as such are a muscle group which is in a shortened position whenever we spend time sitting, either at a desk or in a car during out work days. They also play a huge role in stabilising the hip in a slightly flexed position, during many activities throughout the day.  The very act of sitting on a horse puts the hip flexors into a slightly shortened position and, especially when the true core muscles aren’t doing their fair share, as soon as the horse begins to move we begin to use the hip flexors to help keep us upright and stable over the horses centre of gravity. To add to this complex system of controlling the hip and the core, we must consider the role the gluteal muscles (your butt!) play.

When tight, the hip flexors hold the hip joint in a position of slight flexion, and this is where the problems begin. In a neutral standing position this causes the pelvis to tip forwards and the lumbar spine to be pulled into extension (an increased arch in the lower back). This looks like the first mounted position we saw in the picture in Part 1.

Tightness in the hip flexors is usually also associated with other predictable muscular imbalances around the hips, pelvis and lower back, the most crucial of which is a weak abdominal core and gluteal muscles and a tight lower back and hamstrings . This pattern is often referred to as Lower Crossed Syndrome and creates for the rider a position of ‘duck butt’, lack of suppleness through the lower back, knees which grip and ride up in front of the centre of gravity and a lower leg and heel which just won’t stay where it belongs.

A strong core is crucial for a riders stability in the saddle, and may be the difference between sticking that awkward jump or unexpected stop or not. It also is crucial for allowing the rider to apply effective seat aids. The sum of these imbalances cause the body to move less freely and with less control than the ideal. Often one side is more restricted than the other and this is where many cases of short-stirrup-itis and dropping your hip or tilting one way originate from.

Hip flexor 1

How does this affect your horse? From the seat alone, if one hip flexor is pulling tighter than the other, a tilt to one side is likely to occur. Looking at the shape of the pelvis in the picture above, you can see that tilting the pelvis to the side (dropping a hip/creasing at the waist) will cause one of your sit bones (ischial tuberosity) to contact the horses back more than the other. Thinking about how sensitive we hope for our horses to be to seat aids, one can instantly see the problems this might cause. The horse who always bends one way or is travelling on three tracks and just can’t seem to straighten no matter how much leg the rider applies, which incidentally feels much stronger one way than the other. The changing  or disuniting canter leads. The inability to easily find or maintain the correct diagonal in trot and the horse who looks that little bit lame on one rein in trot but not the other and no clear diagnosis of true lameness can be found.  These are just a handful of the problems created by unevenly tight hip flexors and the postural ramifications of such. When both are tight we typically see the proverbial “”duck butt” rider posture. The horse typically reacts by hollowing to escape the increased weight through the tree points and falls onto the forehand as the riders centre of gravity is thrown forward of the ideal. The horses back end then merrily trails out behind him, pretty much precluding any chance of hip engaging from behind and lifting the shoulder. His own core blows in the wind, while yours does the same up top.

In part 3 we will start to look at how you can test these muscle groups in yourself and where to start to unwind this pattern so you can begin to address the associated problems in yourself and your horses performance.
