[Clinical experiences with the therapy for patella luxation of small animals using sulcoplasty and lateral and cranial relocation of the tuberositas tibiae].

Twenty cases with patellar luxation in dogs and cats, in which a sulcoplasty and cranialisation of the tuberositas tibiae were performed, were investigated and reviewed retrospectively. Twelve knees were available for follow-up after a mean period of 15 months. Clinical scoring of patients showed eight with no lameness, three with an occasional weightbearing lameness, and one with a frequent weightbearing lameness. The patella was stable and could not be luxated in ten out of twelve cases. Degenerative joint disease was slightly progressive in the postoperative period. It did not impair the outcome of the procedure.
