This condition of the knee joint, in which the kneecap (patella) pops out of its natural position to the side, is one of the most common causes of lameness in dogs. This dislocation occurs mainly in growing and older dogs of small breeds. Several of these breeds have a particular genetic predisposition to patella luxation.
In most cases, a slight misalignment of the upper and lower leg bones or a groove that is too shallow is the cause of a dislocated kneecap. In very rare cases, accidents can also lead to patellar dislocation.
To better understand the condition, it is important to know where the kneecap is normally located and what its function is. A long tendon, known as the patellar ligament or patellar tendon, runs from the front of the thigh bone, across the knee joint, to the upper end of the lower leg bone. The kneecap is a small flat bone that is embedded in this ligament in a groove in the thigh bone and, as part of the knee joint, is involved in the smooth bending and straightening of the knee.
If there is a deviation in the bone axis between the upper and lower leg, the straight patellar ligament no longer runs centrally across the knee joint, allowing the kneecap to slip either inward or outward out of its intended groove. In most cases, the kneecap slips inward. The joint can no longer be straightened properly and the natural movement is disrupted. Depending on the severity of the misalignment and the surrounding muscle tension, the kneecap may shift either occasionally or permanently.
If the condition persists for a long time and the kneecap jumps back and forth frequently, the surrounding soft tissue structures and the knee joint can be damaged. If left untreated, osteoarthritis can develop as a result of the incorrect loading.
Patella luxation usually manifests itself in a very typical form of lameness. Affected dogs suddenly stop putting weight on the affected leg for a few steps, even though their gait appears otherwise normal, and then bend it sharply before continuing to walk normally. If the kneecap is permanently displaced, the dog will show signs of significant pain and persistent lameness in the affected leg.
If you suspect that your dog is suffering from patella luxation, you should have it examined by a veterinarian as soon as possible. Your veterinarian will first examine the affected knee joint as part of a general examination and then check the mobility of the kneecap using specific tests. If necessary, they will then take X-rays to determine the severity of the dislocation and any joint damage.
Milder forms of patella luxation can usually be treated successfully with splints or bandages. Physiotherapy and special dietary supplements can be used to strengthen the surrounding connective tissue and muscles. Your veterinarian will be happy to advise you on the right product.
In severe cases of constant or permanent patella luxation with sometimes considerable pain, surgery may be necessary to stabilize the patella in its original position and prevent the development or progression of osteoarthritis of the knee joint. Depending on the severity of the misalignment and dislocation, your veterinarian has a variety of surgical techniques to choose from. During these procedures, the groove can be deepened, the attachment point of the patellar ligament can be moved, and the soft tissue structures can be tightened, among other things. Since every general anesthetic and surgery carries certain risks, your veterinarian will weigh up the pros and cons in each individual case and advise you in detail on whether surgery is advisable.
The prognosis depends on the severity of the patella luxation and the size of the dog. Small dogs generally have a better prognosis than large dogs due to their lower weight. With appropriate treatment, dogs with grade 1 to 3 luxations have a good chance of becoming symptom-free. Dogs with permanent patella luxation have a slightly poorer prognosis. Early treatment is crucial here to prevent secondary damage.
Since it is largely a hereditary condition, patella luxation cannot be directly prevented. However, many breeding associations for endangered breeds already require a certified examination for patella luxation before breeding approval is granted. In this way, they are helping to reduce the spread of the disease.
Like many other pets, our dogs can also suffer from skin fungus. Skin fungal infections occur mainly in young animals, those with weakened immune systems, or those that have been affected by parasites or other diseases. However, the disease is not only a danger to your dog, as many skin fungi are also transmissible to humans and are therefore zoonoses. Elderly and weakened people are particularly at risk of developing a dangerous fungal infection.
It's wonderful that you're thinking about adopting a dog from abroad, because you want to save a life, and that's great! But please be prepared that your new dog may not immediately show you love and gratitude. You should also ask yourself whether you might want to give one of the many dogs in a US animal shelter a chance. Rescuing a dog from abroad also involves risks and problems.
Surgery describes the treatment of diseases and injuries through mechanical intervention on the body. This usually takes place under various forms of anesthesia (numbing). During the procedure, bodily functions and the depth of anesthesia are monitored using modern equipment.
Gynecology and andrology are separate fields of medicine. Gynecology deals with the female reproductive organs, while andrology deals with the male reproductive organs. Both fields cover diseases of the reproductive organs and reproductive medicine. Obstetrics is a branch of gynecology.
With increasing mobility, open borders, and a wide range of travel options, this insidious infectious disease has also become more prevalent in our part of the world. Many dog owners want to have their four-legged friends with them on vacation and therefore travel south with their dogs. More and more rescue dogs are also being brought to Germany from southern Europe and rehomed here, with the result that diseases can also be imported.
Skin fungal infections are also common in chinchillas. The most common are ringworm and bald patch, which cause changes to the fur and skin of chinchillas. Skin fungal infections are not life-threatening, but can lead to persistent problems due to their contagious nature. Skin fungi can also be transmitted to or from humans to animals, which is referred to as a zoonosis.
In dogs, as in humans, the anterior cruciate ligament often tears. This strong ligament connects the thigh bone to the shin bone in the knee joint and prevents the knee from overextending or twisting. However, while cruciate ligament tears in humans are usually traumatic in nature (caused by sports accidents of all kinds), in dogs the ligament gradually breaks down over a longer period of time (degeneration).
The bit attached to the bridle transmits your rein aids to your horse and is therefore a central link in rider-horse communication. As the horse's mouth is a particularly sensitive area, it is important that the bit suits you both. Choosing the right bit depends on the level of training of the rider and horse, the type of riding, the anatomy of the horse's mouth, the temperament and also the preferences of the horse.
Similar to humans, dogs of middle to advanced age can also develop a sugar metabolism disorder. Canine diabetes is the second most common hormone-related disease in dogs. The first noticeable symptoms are increased thirst and increased urination. If diabetes is detected early, the disease can be well controlled with lifelong insulin therapy. However, certain emergencies can also occur in the context of diabetes, requiring immediate veterinary treatment.
Squamous cell carcinoma is a malignant skin tumor that occurs in cats mainly in the mouth, ears, and nose. Starting in the uppermost layer of skin and mucous membrane, the squamous epithelium, this tumor spreads very quickly and aggressively. Cats of all breeds and ages can be affected, although older cats are more susceptible.
What lies behind this almost unpronounceable name? Hyperkalemic Periodic Paralysis is a hereditary, incurable metabolic disease that primarily affects Quarter Horses, Paint Horses, and Appaloosas, whose bloodlines all trace back to the Quarter Horse stallion "Impressive."
Gastroenterology is the branch of internal medicine that deals with the diagnosis and treatment of diseases of the gastrointestinal tract. This also includes the pancreas, liver, and gallbladder.
