A Pug with a prosthetic hind leg. A veterinary prosthesis is a medical device that takes the place of an absent body part for an animal. These devices are created with the intention of mimicking the body part to serve the same purpose and functionality. [1]
Prosthetic joint infections are generally difficult to treat as most causative organisms form a biofilm, or a thickly adherent membrane, against the artificial joint surface. The bacteria secrete adhesion proteins which help them attach to each other and to the joint surface. [ 1 ]
Luxating patella cannot be present without the knee being loose, but a loose knee is not necessarily slipping out of the joint. Even with luxating patella, symptoms such as intermittent limping in the rear leg might be mild or absent. Physical examination and manual manipulation are the preferred methods for diagnosis.
Stifle injuries are one of the most common causes of lameness in rear limbs in dogs, and cruciate ligament injuries are the most common lesion in the stifle joint. A rupture of the cruciate ligament usually involves a rear leg to suddenly become so sore that the dog can barely bear weight on it. [7] How a rupture can occur:
The prosthesis may need to be replaced due to complications such as infection or prosthetic fracture. Replacement may be done in one single surgical session. Alternatively, an initial surgery may be performed to remove previous prosthetic material, and the new prosthesis is then inserted in a separate surgery at a later time.
In infection of a prosthetic joint, a biofilm is often created on the surface of the prosthesis which is resistant to antibiotics. [29] Surgical debridement is usually indicated in these cases. [ 2 ] [ 30 ] A replacement prosthesis is usually not inserted at the time of removal to allow antibiotics to clear infection of the region.
