Relation Of Rehabilitation For Post Surgery
What is relation of canine rehabilitation for post surgeries?
Post-operative patients are the most obvious rehabilitation candidates. Just like in people, dogs need more than just strict rest to fully recover from orthopedic procedures. Surgeons have learned that six weeks of strict cage rest after surgery does not result in healthy dogs or happy owners. Rehabilitation helps ease a dog back into normal activities by safely strengthening the muscles around the weakened bones or joints.
Rehabilitation therapy in veterinary medicine is similar to physical therapy in people, but has some significant differences due the variations in the animal’s anatomy and the extreme forces that can be placed on their joints, bones, tendons and muscles.
EFFECTS OF POSTOPERATIVE REHABILITATION
In an independent experiment conducted on 51 client-owned dogs, weighing between 20 and 40 kg (44 to 88 lb) that had RCCL and medial meniscal injury were studied. After removal of the RCCL and complete medial meniscectomy, the stifle joint was stabilized by use of a lateral retinacular stabilization technique.
25 dogs were included in a postoperative rehabilitation group, and 26 dogs were included in an exercise-restricted group. Limb function (peak vertical force [PVF] and vertical impulse [VI]) was determined before surgery and 6 months after surgery, using force platform gait analysis.
Results—Prior to surgery, mean PVF and VI in affected limbs were similar between groups. Six months after surgery, PVF and VI were significantly increased in dogs of both groups. However, PVF and VI in dogs in the rehabilitation group were significantly greater than those of dogs in the exercise-restricted group. At this time, differences in limb function (as measured by PVF and VI) between the repaired and normal limbs were not evident in dogs in the rehabilitation group. Conversely, limb function in the repaired limb of dogs in the exercise-restricted group was still significantly less than that of the normal limb.

The Benefits of Post Surgery Rehabilitation and Physiotherapy
After a surgery, rehabilitation therapy can be beneficial for animal companions by
- Exercise intolerance
- Reducing inflammation and pain after surgery
- Promoting early weight bearing
- Strengthening supporting tissues
- Decreasing compensatory muscle, myofascial, and back pain
- Providing mental stimulation for pets who have had restricted activity
- Improving coordination and balanceReversing muscle atrophy
- Promoting weight loss if needed
- Developing structured homework program
- Safely promoting faster return to function
THE ROLE OF REHABILITATION IN POST SURGERY
Physical rehabilitation has become a proven staple in human medicine and doctors now recommend physical rehabilitation following a variety of procedures. These same techniques and modalities are now being applied to veterinary medicine. Canine physical rehabilitation is used to improve the performance and quality of movement for our pets as well as speed healing and provide positive psychological effects.
Following certain surgeries pets may lose up to one third of their muscle mass in a matter of weeks and it may take that same pet more than a year to regain the lost muscle mass. Rehabilitation makes it easier and less stressful for patients to return to functional activities in their day to day life. The prognosis for return to function depends on a great number of variables including whether the pet is a working dog or house pet, as well as the degree of injury and overall body condition.

UNILATERAL COXOFEMORAL EXCISION ARTHROPASTY
A coxofemoral excision arthroplasty involves the surgical removal of the femoral head and neck. It is a salvage procedure with the goal to eliminate bone to bone contact at the hip and results in the formation of a functional pseudarthrosis (a scar tissue joint).
It was first described as a treatment for dogs with hip dysplasia in 1961. This surgical option is indicated in cases of canine hip dysplasia, Legg-Calve-Perthés disease, non-reparable fractures of the acetabulum or femoral head, osteoarthritis, chronic recurrent hip luxations, osteomyelitisand septic arthritis, failed total hip replacement or villinodular synovitis of the hip joint.
IMPORTANCE OF POST SURGERY PHYSICAL THERAPY
Physical therapy should be started the day after surgery, and incorporate range of motion (ROM) into flexion, extension and abduction. Aggressive analgesic therapy may assist in early ambulation and rapid return to normal function. As well, use of therapeutic modalities can aid in pain relief and soft tissue healing and hence improved functioning.
However, cases that are not referred for physiotherapy immediately post‐op may exhibit severe loss of range of motion and muscle wastage depending on the length of delay before obtaining these services. The goals in treating these cases are to maximize weight bearing, gain ROM or muscle extensibility, strengthen the affected limb, stimulate soft tissue healing, provide pain relief following an aggressive physiotherapy stretching or exercise treatment session, and address proprioception deficits.
Facilitation of Weight bearing
It is imperative that the animal actually use the post‐operative limb, so any safe exercise that encourage limb use can be utilized. Various therapeutic exercise techniques have been described to stimulate weight bearing on any post‐operative limb.
Gain Range of Motion
Regaining hip extension is a one of the most important goals when rehabilitating this type patient. Passive range of motion (PROM) may help to regain extension, however an animal that has been avoiding this movement, the physiotherapist will need to be tricked into extending its hips.
Atrophy of the hind limb muscle mass should be addressed post‐operatively. Various treatment techniques can be used to strengthen the muscles of the hip and thigh. For dogs that are unable to walk, NMES and TENS are often applied.
Pain relief and soft tissue healing
The FHNE surgery may have resulted in adhesions to the distal muscle secondary to tracking of blood from the surgical site and soft tissue damage done at the same time. As well, the techniques listed above may result in mild soft tissue soreness. Therapies that may address this could include modalities and/or massage.
It is well known that healing of soft tissue structures can be accomplished with ultrasound, Low Level Light Therpy (LLLT or also commonly known as Cold Laser), or pulsed electromagnetic field therapy. The tissues surrounding the hip joint as well as the quadriceps and sartorius muscle may benefit from these treatments in regards to the surgically induced trauma. Non‐noxious sensory stimuli reduces blood pressure, changes secretion of corticotropin releasing hormone and increases pain thresholds in rats.
In humans, it produces pain relief and increase the plasma concentration of B‐endorphins. All of these effects could provide comfort to the animal, hence encouraging use and relieving post‐exercise discomfort.
As the limb begins to heal and the dog is utilizing it consistently in gait, the next goal should be to retrain proprioception of the affected leg. Proprioception is the minds awareness of the where the body is in space. Several exercises have been described to address co‐ordination and muscular control of a limb.
