Objective—To evaluate owners' perceptions of the
outcomes of dogs that have undergone total hip
Sample Population—Owners of 145 dogs that had
Procedure—Surveys were mailed to owners of 353
dogs that underwent THA between 1982 and 1996.
Owners were asked to answer multiple-choice questions
and provide written comments.
Results—The response rate was 41%. For owners
who responded to the survey, time from surgery to
completion of the questionnaire ranged from 6
months to 11 years. Overall, 122 respondents (84.1%)
rated results of THA in their dog as excellent or good.
Conclusion and Clinical Relevance—Results suggest
that owners are generally satisfied with the
results of THA in their dogs. (J Am Vet Med Assoc
Objective—To identify risk factors for development of excessive tibial plateau angle (TPA) in large-breed dogs with cranial cruciate ligament disease (CCLD).
Animals—58 dogs with excessive TPAs (ie, TPA ≥ 35°; case dogs) and 58 dogs with normal TPAs (ie, TPA ≤ 30°; control dogs).
Procedures—Medical records and radiographs were reviewed and owners were interviewed to identify potential risk factors for excessive TPA.
Results—Case dogs were 3 times (95% confidence interval, 1.2 to 8.0) as likely to have been neutered before 6 months of age as were control dogs. Case dogs with TPA ≥ 35° in both limbs were 13.6 times (95% confidence interval, 2.72 to 68.1) as likely to have been neutered before 6 months of age as were control dogs with TPA ≤ 30° in both limbs. Case dogs were significantly younger at the onset of hind limb lameness than were control dogs.
Conclusions and Clinical Relevance—Results suggested that early neutering was a significant risk factor for development of excessive TPA in large-breed dogs with CCLD. Further research into the effects of early neutering on TPA and the pathophysiology of CCLD is warranted.
