Nine stifle arthrodeses in eight dogs were reviewed retrospectively to evaluate use of the limb, each dog's comfort, complications, and factors that may have influenced the final outcome. Ability to use the limb after unilateral fusion was good (limb used at all times) in three dogs, fair (limb used at all gaits except a gallop) in three dogs, and poor (limb used only when running) in one dog. Factors that appeared to affect the outcome included angle at which the stifle was fused and lesions in the ipsilateral coxofemoral joint. One dog with bilateral arthrodesis had a good outcome with minor limitations. The only potentially devastating complications occurred in one dog in which infection and premature implant loosening jeopardized the fusion. None of the dogs exhibited signs of pain and all owners were satisfied with the results.
