Management of concurrent patellar luxation and cranial cruciate ligament rupture using modified tibial plateau levelling.

Summary:

To evaluate a novel surgery aimed at managing concurrent medial patellar luxation (MPL) and cranial cruciate ligament(CCL) ruptures in dogs weighing more than 30 kg.

Conclusion:

Thirteen surgeries were performed in 12 dogs with a mean weight of 39.8 kg. The mean postoperative tibial plateau slope was 8.1 degrees. Additional surgery was required in two cases, one due to failure of fixation and another due to screw breakage. The mean lameness score was 3.5 (out of 5) before surgery, 0.7 after 8 to 12 weeks, and 0.3 at final follow-up. Median follow-up was 1115 days (range, 270 to 2040 days). No patella luxated after surgery.

Epidemiology of Cranial Cruciate Ligament Disease Diagnosis in Dogs Attending Primary-Care Veterinary Practices in England.

Summary:

To estimate the prevalence and risk factors for a diagnosis of cranial cruciate ligament (CCL) disease in dogs and to describe the management of such cases attending primary-care veterinary practices.

Conclusion:

Breed predispositions and demographic factors associated with diagnosis and case management of CCL disease in dogsidentified in this study can be used to help direct future research and management strategies.

Arthroscopic documentation of elbow cartilage pathology in dogs with clinical lameness without changes on standard radiographic projections.

Summary:

To document cartilage damage associated with elbow lameness in dogs without radiographic signs.

Conclusion:

Elbow pathology not associated with radiographic changes can be identified by CT and scintigraphy. Coronoid pathology is the most likely diagnosis.

Clinical comparison of a novel extracapsular stabilization procedure and tibial plateau leveling osteotomy for treatment of cranial cruciate ligament deficiency in dogs

Summary:

To develop and test a novel extracapsular technique, TightRope CCL technique (TR), and compare its 6-month clinicaloutcomes to tibial plateau leveling osteotomy (TPLO) in dogs with cranial cruciate ligament (CCL) deficiency.

Conclusion:

TR resulted in 6-month outcomes that were not different than TPLO in terms of radiographic progression of OA and client-evaluated level of function. TR was associated with shorter anesthesia and surgery times as well as a lower complication rate.

Canine hip dysplasia treated by juvenile pubic symphysiodesis. Part II: two year clinical results.

Summary:

To determine the clinical effects of juvenile pubic symphysiodesis (JPS) treatment in hip dysplasia-prone puppies with comparison to similar untreated control puppies.

Conclusion:

In JPS dogs with preoperative mild to moderate hip laxity (DI = 0.40-0.69), insignificant osteoarthritis occurred at two years. Juvenile pubic symphysiodesis surgery also improved other clinical criteria (Ortolani, HRA, hip pain, N-DIS). Osteoarthritis was generally not prevented by JPS in dogs with initial severely lax hips (DI≥0.70). Juvenile pubic symphysiodesissurgery at 12 to 24 weeks of age was an effective and safe pre-emptive bilateral treatment for mild to moderate hip dysplasia.

The cruciate ligaments of the canine stifle: an anatomical and functional analysis.

Summary:

Fifty canine stifles were used to study the anatomy and function of the cruciate ligaments.

Conclusion:

It was found that both cruciate ligaments were composed of 2 component parts and that the geometry of their femoral attachments was responsible for a reciprocal loosening and tightening of these components through a range of motion. It was also found that transection of one or both cruciate ligaments resulted in marked joint instability.

Short-term and long-term outcomes for overweight dogs with cranial cruciate ligament rupture treated surgically or nonsurgically.

Summary:

To determine short- and long-term rates of successful outcomes of surgical and nonsurgical treatments for overweight dogswith cranial cruciate ligament rupture (CCLR).

Conclusion:

Overweight dogs with CCLR treated via surgical and nonsurgical methods had better outcomes than dogs treated via nonsurgical methods alone. However, almost two-thirds of the dogs in the nonsurgical treatment group had a successful outcome at the 52-week evaluation time.

Canine elbow dysplasia: anatomy and pathogenesis.

Summary:

Canine elbow dysplasia is a complex of diseases that includes ununited anconeal process, fragmented medial coronoid process, osteochondrosis of the medial humeral condyle, and elbow incongruity. Three causes of elbow dysplasia have been proposed: osteochondrosis, trochlear notch dysplasia, and asynchronous growth of the radius and ulna.

Prevalence of and risk factors for hip dysplasia and cranial cruciate ligament deficiency in dogs

Summary:

To evaluate prevalence of and risk factors for hip dysplasia (HD) and cranial cruciate ligament deficiency (CCLD) in dogs and determine change in prevalence over time.

Conclusion:

Results suggested that sex, age, and breed were risk factors for HD, CCLD, or both in dogs and that prevalences of HD and CCLD have increased over time.

Tibial tuberosity transposition-advancement for treatment of medial patellar luxation and concomitant cranial cruciate ligament disease in the dog. Surgical technique, radiographic and clinical outcomes.

Summary:

To report surgical technique, morphometric effects and clinical outcomes for tibial tuberosity transposition-advancement(TTTA), sulcoplasty and para-patellar fascial imbrication for management of concomitant medial patellar luxation (MPL) and cranialcruciate ligament (CCL) disease in 32 dogs.

Conclusion:

Thirty-nine stifles were treated by surgery. Medial patellar luxation grade ranged from II to IV/IV. The CCL rupture was complete in 17/39 stifles, and incomplete in 22/39. Complications occurred in 11/39 stifles including MPL recurrence (n=4). Resolution of subjectively-assessed lameness occurred in 29/39 stifles at the six to eight week assessment. Resolution of lameness was eventually documented in 35/39 stifles (4/39 lost to follow-up), and was maintained at the six to 20 month reassessment where available. The TTTA induced relative patella baja in 31/39 stifles. Magnitude of actual tibial tuberosity advancement was lower than that predicted by cage size.
