Objective: To characterize the effect of a titanium-alloy anchoring system (TAS) on the motion of the cranial cruciate ligament (CrCL) deficient stifle. To compare the motion with the TAS to that of the CrCL-intact and CrCL-deficient stifle.Study Design: Each canine pelvic limb was mounted in a loading jig under 30% body weight. Motion data was collected using an electromagnetic tracking system at stifle angles of 125°, 135°, and 145° with the CrCL-intact, CrCL-deficient and the TAS applied.Results: Total translation of the CrCL-deficient stifle following the TAS was reduced, but remained greater than the CrCL-intact stifle at angles of 125°, 135°, and 145°. Internal rotation of the TAS groups was greater than the CrCL-intact group at 145°, but not 125° and 135°. Varus motion of the TAS group was decreased compared to the CrCL-deficient group, but increased compared to the CrCL-intact group at angles of 125°, 135°, and 145°.Conclusion: Total translation and internal rotation of the CrCL-deficient stifle following the TAS differed from that of the CrCL-intact stifle. However, the TAS reduced total translation and internal rotation of the tibia relative to the femur in the CrCL-deficient stifle to levels that may yield clinically acceptable results.

SummaryIn this report, a case of cranial cruciate ligament (CrCL) rupture treated by tibial plateau levelling osteotomy (TPLO), in a 36-month-old male breeding alpaca, is described. The alpaca was presented with the complaint of acute onset of right pelvic limb lameness. The findings of our clinical and radiographic examinations were consistent with CrCL insufficiency of the right stifle joint. The right tibial plateau angle measured prior to surgery was 19°. A TPLO was performed and this eliminated cranial tibial thrust. Culture of a swab taken from the surgical site prior to wound closure was positive for Pseudomonas aeruginosa. Enrofloxacin was administered parenterally for two weeks postoperatively. There were not any clinical signs of infection noted. Outcome assessments included veterinary examination (two and six weeks) and owner assessment (28 months). At two weeks the animal walked with a grade 2/5 lameness, and at six weeks radiographic examination showed progression of bone healing at the site of tibial osteotomy. A return to full breeding fitness occurred by eight weeks after the surgery. The alpaca remained free from lameness 28 months later, according to the owner.

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°. Surgical correction was performed with a combination of tibial plateau leveling osteotomy and cranial closing wedge ostectomy. The procedures resulted in an excellent clinical outcome with immediate return to weight bearing in the operated limb and progressive improvement in function over the ensuing 4 months.

Cranial Cruciate Ligament Rupture

AbstractThe aim of this study was to report a case of caudal cruciate ligament rupture in a 9-year-old dog who underwent juvenile tibial plateau cranial hemiepiphysiodesis that was performed to treat a partial cranial cruciate ligament rupture and excessive tibial plateau angle. A 9-year-old, 45 kg, male Bernese Mountain dog was referred for a non-traumatic acute right pelvic-limb lameness. At the age of 5 months, the dog underwent bilateral tibial plateau cranial hemiepiphysiodesis to treat a bilateral partial cranial cruciate ligament rupture and excessive tibial plateau angles. At clinical examination, a caudal tibial subluxation of the right stifle was detected. The right tibial plateau angle was 3 degree. Arthroscopy confirmed a complete caudal cruciate ligament rupture. The cranial cruciate ligament was partially torn. A diagnosis of caudal cruciate ligament rupture 8.5 years post juvenile tibial plateau hemiepiphysiodesis was made. A tibial plateau overcorrection might have contributed to caudal cruciate ligament rupture in this dog.

A 6-month-old red wolf (Canis rufus) pup presented for evaluation of progressive thoracic and pelvic limb lameness, joint swelling, and decreased body condition. Radiographic evaluation revealed medullary sclerosis centered at the metaphyses of multiple long bones, well-defined irregular periosteal proliferation, and ill-defined lucent zones paralleling the physes, consistent with hypertrophic osteodystrophy (HOD). Biopsies of affected bone revealed medullary fibrosis and new bone formation. The pup improved following treatment with nonsteroidal anti-inflammatories, opioids, and supportive care over the course of 4 weeks. Metaphyseal periosteal bone proliferation persisted until the animal was humanely euthanized several years later for poor quality of life associated with bilateral cranial cruciate ligament rupture. A second red wolf pup of 4.5 months of age presented for evaluation of lethargy, kyphotic posture, and swollen carpal and tarsal joints. Radiographs revealed bilateral medullary sclerosis and smooth periosteal reaction affecting multiple long bones, suggestive of HOD. Further diagnostics were not pursued in this case to confirm the diagnosis, and the clinical signs persisted for 4 weeks. In light of these two case reports, HOD should be recognized as a developmental orthopedic disease in growing red wolves.

Stance Duration

SummaryObjectives: To establish the effect of tibial plateau levelling osteotomy (TPLO) on two selected pelvic limb kinematic variables in dogs treated for clinical cranial cruciate ligament rupture (CCLR).Methods: Thirteen dogs that had incurred CCLR and were treated by TPLO walked on a treadmill whilst kinematic data on pelvic limb paw motion were acquired using motion capture equipment. Data were subject to secondary processing using matrix analysis software and statistical analysis.Results: Pelvic limb stance duration significantly increased during the 12 week study period, recovering to near-normal values. Range of pelvic limb paw velocity also significantly increased but did not reach normal values by 12 weeks postoperatively.Clinical significance: The improvement in stance duration to near normality may aid in explaining the widely-held subjective impression that TPLO frequently provides an excellent outcome in the early stages after repair of the cruciate deficient canine stifle joint. Both stance length and range of paw velocity provide useful objective measures to compare outcome following surgery for CCLR.

SummaryA test apparatus that allowed the stifle to move in five degrees of freedom was used to determine the effect of graft location, graft preload, and flexion angle at the time of graft fixation on the tensile graft forces experienced by a replacement graft material used to simulate reconstruction of the cranial cruciate ligament deficient stifle. Two graft locations (tibial insertion site of the patellar ligament and tibial insertion site of the cranial cruciate ligament), two graft preloads (5 N and 20 N), and three flexion angles at the time of graft fixation (15°, 30° and 90°) were examined. The tibial insertion site and preload did not have as great an effect on graft force as did the flexion angle of the limb at time of graft fixation. Graft forces were highest when reconstructions were performed with the limb in 90° of flexion (ρ <0.0001). This study supports the notion that intracapsular grafts should be fixed with the limb in a normal standing angle.A five degree of freedom test apparatus was used to evaluate the effect of graft location, graft preload, and limb flexion angle at time of graft fixation on reconstructions of the cranial cruciate ligament deficient stifle. Our results suggest that intracapsular grafts should not be fixed with the limb in 90° of flexion, but in a normal standing angle.
