Canine knee injuries are a common concern among dog owners, affecting various breeds and sizes. These injuries can significantly impact a dog's mobility, comfort, and quality of life. Understanding the different types of knee injuries and the pathways for rehabilitation is crucial for ensuring the best possible outcomes for our doggo companions.
Types of Canine Knee Injuries
Cruciate Ligament Tears
The cruciate ligaments, namely the cranial cruciate ligament (CCL), are vital for stabilising the knee joint in dogs. Tears or ruptures in the CCL are among the most common knee injuries in canines, often resulting from sudden trauma or degenerative changes. Dogs with cruciate ligament tears typically exhibit lameness, swelling, and difficulty bearing weight on the affected limb.
Patellar luxation involves the dislocation of the kneecap (patella) from its normal position within the groove of the femur. This condition can be congenital or acquired and may vary in severity from intermittent to permanent dislocation. Symptoms include intermittent limping, skipping, or "locking" of the knee joint.
The menisci are cartilage structures within the knee joint that provide cushioning and stability. Injuries to the menisci commonly accompany cruciate ligament tears but can also occur independently. Dogs with meniscal injuries may exhibit lameness, joint swelling, and pain, particularly during movement.
Conservative management is an approach to treating canine knee injuries without resorting to surgical intervention. This method is often considered in cases where surgery may not be feasible or necessary, such as in older dogs, those with concurrent health issues that increase surgical risks, or in instances where the injury is mild to moderate.
Here's a more in depth exploration of conservative management strategies for canine knee injuries.
Maintaining a healthy body weight is crucial for dogs with knee injuries, as excess weight can exacerbate strain on the joint and impede healing. A balanced diet, portion control, and appropriate exercise regimens tailored to the dog's needs can help achieve and maintain a healthy body weight.
Pain relief is an integral component of conservative management and may involve the use of non-steroidal anti-inflammatory drugs (NSAIDs) prescribed by a veterinarian to alleviate discomfort and reduce inflammation. Other pain management modalities, such as joint supplements (e.g., glucosamine and chondroitin), nutraceuticals, or alternative therapies like acupuncture, may also be considered to enhance pain relief and support joint health.
Physiotherapy and Rehabilitation
Physiotherapy modalities can play a significant role in conservative management by promoting healing, reducing pain, and improving joint function. Common physiotherapy techniques include:
Orthopaedic devices, such as knee braces or supportive wraps, may be recommended in some cases to provide additional stability and support to the injured knee joint. These supports can help alleviate discomfort, reduce inflammation, and improve proprioception while the knee heals.
Regular Monitoring and Follow-Up
Close monitoring of the dog's progress is essential during conservative management, with regular follow-up appointments scheduled to assess response to treatment and make any necessary adjustments to the management plan. Radiographic imaging or other diagnostic tests may be repeated periodically to evaluate healing and monitor for any changes in the condition of the knee joint.
Conservative management can be an effective approach for managing certain canine knee injuries, particularly in cases where surgery may not be indicated or desired. However, it's important to work closely with a veterinarian and rehabilitation expert to develop a comprehensive treatment plan tailored to the individual dog's needs and condition. With proper care, many dogs can experience significant improvement in their mobility and quality of life through conservative management strategies.
Surgical intervention is often recommended for severe or progressive knee injuries, especially cruciate ligament tears and advanced cases of patellar luxation. Common surgical procedures include:
Tibial Plateau Leveling Osteotomy (TPLO)
TPLO is a surgical procedure primarily used to address cranial cruciate ligament (CCL) tears, which are one of the most common knee injuries in dogs. During TPLO, the veterinarian makes an incision over the knee joint and cuts the top portion of the tibia (shinbone). The angle of the tibial plateau is then altered and stabilised using specialised plates and screws, effectively changing the biomechanics of the knee joint. By altering the angle of the tibial plateau, TPLO reduces the need for the cranial cruciate ligament, providing stability to the knee joint during weight-bearing activities. TPLO is known for promoting faster and more reliable healing compared to some other surgical techniques.
Cranial Cruciate Ligament Repair (CCLR)
CCLR involves repairing or replacing the torn cranial cruciate ligament (CCL) to restore stability to the knee joint. There are several techniques used for CCLR, including:
Patellar Realignment Procedures
Patellar luxation, where the kneecap (patella) dislocates from its normal position, may require surgical intervention if conservative measures fail to provide relief. Surgical procedures for patellar luxation aim to realign the patella and correct any underlying anatomical abnormalities contributing to the dislocation. Common procedures include:
The specific procedure chosen depends on factors such as the severity of the luxation, concurrent orthopaedic issues, and the dog's size and breed.
These surgical procedures aim to restore stability and function to the knee joint, alleviate pain, and improve the dog's overall quality of life. It's essential to discuss the available surgical options with a veterinarian or veterinary surgeon to determine the most suitable approach based on the individual needs of the dog. Additionally, post-operative rehabilitation is crucial for optimising recovery and maximising the success of the surgical intervention.
Post-operative rehabilitation plays a vital role in the recovery process following surgical intervention for canine knee injuries. Below is and extended and detailed exploration of rehabilitation strategies and modalities.
Controlled Exercise Regimens
Controlled exercise is crucial during the rehabilitation period to promote healing, rebuild strength, and restore normal joint function. Initially, exercise should be limited to short, leash-controlled walks to prevent excessive strain on the surgical site. As the dog progresses, the veterinarian or rehabilitation specialist may recommend gradually increasing the duration and intensity of exercise, incorporating activities such as controlled leash walking, gentle jogging, and low-impact exercises. It's essential to avoid activities that may put undue stress on the knee joint, such as jumping, running on slippery surfaces, or rough play, especially during the early stages of rehabilitation.
Joint Mobilisation and Range of Motion Exercises
Joint mobilisation techniques, including passive range of motion exercises, help maintain or improve joint flexibility and prevent stiffness. These exercises may involve gently moving the affected joint through its full range of motion, guided by a trained rehabilitation therapist. Range of motion exercises should be performed regularly but carefully to avoid overstretching or causing discomfort to the dog.
Various therapeutic modalities can aid in pain management, reduce inflammation, and promote tissue healing. Common modalities include:
Balance and Proprioception Training
Balance and proprioception exercises focus on improving the dog's awareness of limb placement and joint position, thereby enhancing stability and coordination. These exercises may include standing on unstable surfaces (e.g., balance pads or balance balls), walking over obstacles of varying heights, and performing controlled weight-shifting movements. Balance and proprioception training help retrain the neuromuscular system, reducing the risk of re-injury and improving overall functional performance.
Hydrotherapy, which involves controlled exercises performed in water, plays a crucial role in the rehabilitation process for dogs recovering from knee injuries. Here's why hydrotherapy is considered an essential component of canine knee injury rehabilitation.
Hydrotherapy provides a low-impact environment for dogs to exercise, allowing them to engage in physical activity without placing excessive stress on the injured knee joint. The buoyancy of water supports the dog's body weight, reducing the strain on the joints while still allowing for effective conditioning and muscle strengthening.
Improved Range of Motion
The resistance and buoyancy of water create a dynamic environment that promotes increased joint mobility and range of motion. Performing exercises in water allows dogs to move their joints through a greater range of motion than they might be able to achieve on land, facilitating joint flexibility and reducing stiffness.
Hydrotherapy exercises target and strengthen the muscles surrounding the knee joint, helping to stabilise the joint and prevent further injury. Resistance provided by the water encourages muscle engagement and development, promoting overall strength and endurance.
Pain Relief and Reduced Inflammation
The hydrostatic pressure of water can help reduce swelling and inflammation in the injured knee joint, providing natural pain relief. Immersion in warm water can also have a soothing effect on sore muscles and joints, promoting relaxation and alleviating discomfort.
Hydrotherapy sessions can be designed to incorporate aerobic exercises, such as swimming or walking on an underwater treadmill, to improve cardiovascular fitness. Aerobic conditioning helps increase stamina and endurance, enhancing the dog's overall fitness level and promoting weight management.
Enhanced Proprioception and Balance
Hydrotherapy exercises challenge the dog's proprioceptive abilities, or their sense of body awareness and position in space. Performing exercises in water requires dogs to adjust their movements to maintain balance and stability, thereby improving proprioception and coordination.
Safe and Controlled Environment
Hydrotherapy sessions are typically conducted under the supervision of trained professionals, ensuring that exercises are performed safely and effectively. Water depth, temperature, and resistance can be adjusted to meet the specific needs and abilities of each dog, making hydrotherapy suitable for dogs of all ages and fitness levels.
Positive Reinforcement and Enjoyment
Many dogs enjoy water-based activities, making hydrotherapy sessions a positive and enjoyable experience for them. The positive reinforcement associated with hydrotherapy can motivate dogs to actively participate in their rehabilitation program, leading to better compliance and outcomes.
Nutrition and Monitoring
Nutritional Support and Weight Management
Proper nutrition and weight management are essential components of rehabilitation, especially for overweight or obese dogs. Maintaining a healthy body weight reduces stress on the joints and facilitates recovery from surgery. A balanced diet rich in high-quality protein, essential fatty acids, vitamins, and minerals supports tissue repair and muscle strength.
Regular Monitoring and Adjustments
Throughout the rehabilitation process, close monitoring by a veterinarian or certified rehabilitation therapist is essential. Progress should be assessed regularly, and the rehabilitation plan may need to be adjusted based on the dog's response to treatment, changes in condition, or any emerging issues. Open communication between the pet owner and the rehabilitation team is crucial to ensure the best possible outcomes for the dog's recovery.
By incorporating these rehabilitation strategies and modalities into the post-operative care plan, pet owners can help their dogs recover from knee injuries more effectively, regain mobility, and improve their overall quality of life. It's important to work closely with veterinary and rehabilitation professionals to develop a tailored rehabilitation program that addresses the specific needs and capabilities of the individual dog.
Canine knee injuries can significantly impact a dog's mobility and quality of life. Understanding the different types of knee injuries and the available pathways for rehabilitation is essential for effectively managing these conditions.

The first time I ever heard about FHO surgery I was shocked to learn of the high success rates for doggo patients who have made the decision to undertake this somewhat radical approach to solving an all too common problem. As a hydrotherapist, planning a recovery program for a dog who has recently completed FHO surgery at first appeared daunting but when you have amazing patients and doggo owners who follow the plan step-by-step, what once appeared as daunting suddenly becomes one of the most rewarding rehabilitation cycles of my career. In this blog, we will dive into FHO surgery, what it entails and the plan towards a successful recovery using both hydrotherapy and physiotherapy as the main focal points on the journey to success.
What is FHO?
Canine femoral head and neck excision (FHO) surgery is a procedure that addresses hip joint issues in dogs, providing relief and improved mobility.
FHO is commonly performed to alleviate pain and discomfort associated with hip dysplasia, fractures, arthritis, or other conditions affecting the hip joint. It involves the removal of the femoral head and neck, allowing the formation of a "false joint" with surrounding muscles and tissues.
During FHO surgery, the surgery removes the femoral head (the ball part of the ball-and-socket joint) and sometimes the neck of the femur. This eliminates the bone-on-bone contact that causes pain, and the body adapts by forming a pseudo-joint, utilising surrounding muscles for stability.
The Road to Recovery
Every journey starts out best with a proper plan or road map in place so that all parties involved are aware of the recovery process and what steps to take next to ensure the best recovery and rehabilitation possible.
After FHO surgery, dogs will need rest and restricted activity. Pain medications and the beginning of some rehabilitation therapy will also be prescribed to manage discomfort and aid in the recovery process. Controlled exercise is crucial during the recovery phase. Short, on-leash/guided walks can help prevent muscle atrophy and promote joint mobility. Avoiding activities that place excessive strain on the hind legs, such as running or jumping is of the most importance at this early stage.
Most Vets will ask patients to seek a physiotherapist post-surgery to aid and assist in the recovery process. Joint mobilisation exercises, massage and the use of laser therapy will all go a long way to promote strength and flexibility to aid in the recovery process as this is also a crucial time to be aware of potential complications that could quickly derail the road to recovery. These complications, such as infection or persistent lameness, need to be addressed as soon as they are noted and the safest option if there is ever any doubt would be to return to the vet for further review.
As each patient progresses in recovery, the vet may gradually allow increased activity. However, it's essential to remain cautious and avoid pushing your dog too quickly, ensuring a steady and safe return to normal activities. This is the perfect time to add hydrotherapy to your recovery plan to not only continue in aiding the road to recovery but to also help build and manage muscles in the hind limbs and lower back.
