The objective of the present study was to determine the tibial plateau angle (TPA) in cats without stifle pathology and to compare it with cats suffering from an isolated cranial cruciate ligament rupture. Mediolateral radiographs of the stifle were taken and the tibial plateau angle was measured based on the method previously described by Slocum and Devine (1983) for dogs. Three observers with different levels of experience evaluated the radiographs of all of the cats in this study.

OBJECTIVE: To compare values for tibial plateau angle (TPA) obtained in dogs by conventional and digital methods. DESIGN: Evaluation study. ANIMALS: 37 dogs with stifle joint abnormalities. PROCEDURES: In all dogs, radiographs of both stifle joints were obtained by conventional and digital means. On conventionally acquired radiographs, TPA was measured with a protractor and fine-point pencil in accordance with standard guidelines. A software program was used to measure TPA on digitally acquired radiographs. Two viewers with different levels of experience performed all measurements 3 times.

The goal of this study was to evaluate different minimally invasive surgical options as therapy for cranial cruciate ligament rupture and resulting meniscal injuries. In this study, 81 stifle joints of dogs with complete or partial rupture of the cranial cruciate ligament were treated with minimally invasive surgery at the Small Animal Clinic of the University of Veterinary Medicine in Hannover. The patients were divided into three groups depending on intraoperative diagnosis and the surgical technique applied.

The influence of the tibial tuberosity conformation on cranial cruciate ligament (CrCl) rupture was evaluated and the size of the tibial tuberosity of healthy dogs (group H) was compared with dogs with CrCl rupture (group R) and dogs treated by tibial tuberosity advancement (TTA) (group T). The medio-lateral radiographs of 219 stifle joints were evaluated. Relative tibial tuberosity width (rTTW), proximal tibial tuberosity angle (PTTA), tibial plateau angle (TPA), tibial width (TW) and tibial plateau length (TPL) were measured on each radiograph.

Objective-To report the complication rate for a commonly performed procedure (lateral fabellotibial suture [LFS]) used in the treatment of dogs with cranial cruciate ligament (CCL) injury. Design-Retrospective case series. Animals-305 dogs evaluated for 363 incidents of CCL injury from January 1997 through December 2005 and treated with LFS.

Stress fractures of the patella were diagnosed in 34 cats with a mean age of two years and five months. Eighteen of the cats had bilateral fractures with a median interval of three months between fractures. All the fractures were transverse and occurred in the proximal aspect or base of the patella with no evidence of trauma. In 43 of the patellae there was radiographic evidence of sclerosis. Repairs with a pin and tension band in 18 cats resulted in a further fracture or failure of fixation in 86 per cent of the cases that were followed up.
