A report on hospitals released Tuesday ranked Rady Children's Hospital second countrywide in orthopedics.

The ranking appeared in the ninth annual 'Best Children's Hospitals' was published by US News and World Report, one of the program that assess hospital quality using a range of often-conflicting criteria.

US News ranks the top 50 pediatric hospitals across 10 categories of care from cancer to urology. The final list is being released after the survey of nearly 183 facilities across the nation.

In 2015, Rady made the top 50 in all 10 specialties and regained the No. 2 ranking in orthopedics, which it last held in 2012.

However, Rady's ranking dropped from the previous year in eight of 10 categories considered. It was found that only its orthopedics ranking increased.

Also, the hospital was not among a dozen named to the magazine's 'Hospital Honor Roll', reserved for those that scored in the top 10 percent in at least three different specialties.

It was told that Boston Children's Hospital was the top-ranked facility nationwide, and Children's Hospital Los Angeles had the best results in California, coming in at No. 7.

Dr. Donald Kearns, Rady's chief executive, said, "The report recognition, and especially the orthopedic ranking, validates the work of doctors, nurses and staffers who care for patients. We're ecstatic that we continue to be rated in all 10 specialties".

He said the hospital will go through the report in order to determine why some rankings slipped as compared to last year's ranks.

Rady has been giving an outstanding performance in orthopedics. The program has been among the top 10 for years, moving from third to second this year after being listed seventh in 2013 and second in 2012.
