Arthroscopic Surgery in Dogs

Arthroscopic surgery is a minimally invasive procedure that is used to explore, examine, and treat the joints of a dog. It can be used for diagnostic purposes also, especially if x-rays have not revealed the cause of joint issues. An arthroscopic camera is inserted into the dog through a small portal incision for visualization. 

Other incisions may be made for various surgical tools to be used on the joint. The stifle (knee) joint is most commonly operated on, but the elbows, shoulders and intertarsal joints may also be treated with arthroscopic surgery. An ACVS board-certified veterinary surgeon should be used to perform this procedure. 

To determine whether the dog will be able to withstand surgery, blood work will need to be run. This will reveal its overall health and indicate whether the animal will be able to survive anesthesia. If surgery is deemed appropriate, the surgeon will plan the procedure. It is usually necessary for the dog to fast for several hours prior to the operation beginning.

To begin the surgery, the area of the affected joint will be shaved. Then, small portal incisions will be made. An arthroscopic camera will be inserted through one of these portal incisions. Tools for tissue or bone removal can then be placed in the other portal incisions. Tools used for this surgery include forceps or a power shaver. If any osteochondral fragments are found during the procedure, they will need to be removed. If defects exist that diminish blood supply, they will need to be corrected at this point. The incisions may be stitched shut upon the removal of the camera and tools. 

The dog will need to be closely monitored as it wakes up from the general anesthesia. As it regains consciousness, pain medication should be administered. A prescription for oral pain management may be given for several days upon discharge. Once the animal is home, the incision site will need to be checked daily for signs of infection. 

An Elizabethan collar may be used to prevent the dog from licking or biting at its incisions. The dog's activity should be limited throughout the healing process. A follow-up appointment will be needed two weeks after the operation to assess healing. If the surgery was for diagnostic purposes, a treatment regime may be initiated at this appointment.

As with any surgical procedure, there are risks associated with the use of general anesthesia. Healthy dogs tend to do better than dogs with other diseases. If certain rare issues are discovered during arthroscopic surgery, a second incisional surgery may be deemed necessary. 

In most cases, fluid will leak from the affected joint, resulting in swelling after the surgery has been performed. This generally resolves on its own within a week. The surgical site may become infected, although this is extremely uncommon with small portal incisions. This surgery is associated with lower pain and risk than its alternatives. Most dogs receive a good outcome from the surgery.
