Procedures: Sterile IM implantation of shot metals was performed, with euthanasia and necropsy at 2, 8, 16, and 26 weeks after implantation.

Tibial plateau leveling osteotomy and cranial closing wedge ostectomy in a cat with cranial cruciate ligament rupture.

A 5-year-old domestic shorthair cat was presented for a nonweight-bearing left pelvic-limb lameness. Orthopedic and radiographic examinations revealed a cranial cruciate ligament rupture and deformity of the proximal tibial metaphysis. The deformity of the proximal tibia resulted in an exaggerated tibial plateau angle of approximately 75 degrees.
