Dr. Bose Discusses the ASR Withdrawal

I have to start by saying that I have never had any issues with the ASR devise at all. I was very surprised about 6 months ago when the issue of ASR withdrawal first surfaced. There is no doubt that the safety margin for the ASR is lower than other resurfacing systems like the BHR due to a 'low arc of cover'- described by Dr. Desmet. This is because the rim of the cup has become 'non -articular' to accommodate the cup holder. Hence the failure rate is higher than the BHR.

The cups coming loose is certainly not true as I have implanted ASR cups in the most complex of cases. I am 100% confident that it is a technical issue.

It has proven to be an excellent tool in my hands and in dysplasia patients ( CROWE 3)- the s-rom with a ASR cup combination that is hard to beat.

The ASR reamers are very poor and not matched to the ASR cups. I have routinely used BHR or equivalent reamers for the ASR cups for 3 yrs since the time noticed the mismatch between the reamers and cup size for the ASR

The ASR has been excellent tool to provide an anatomical metal on metal articulation in small patients. I am very confident that it will work well if installed correctly. I will surely miss the ASR cup for small made patients if it is withdrawn completely.

Hospitals more specialized in orthopedic surgery show better outcomes for hip and knee replacement

A recent study of Medicare data by University of Iowa investigators indicates that hospitals with a higher degree of orthopedic specialization provide better outcomes for patients undergoing hip or knee replacement surgery.

The findings, which appear in the online version of the British Medical Journal, were based on a retrospective study of nearly 1.3 million Medicare beneficiaries aged 65 years and older who had hip or knee replacement procedures between 2001 and 2005 at 3,818 U.S. hospitals. The investigators grouped the hospitals into five categories according to their degree of orthopedic specialization. Orthopedic procedures accounted for 10.5% of admissions at the average hospital, while they represented 14.5% or more of the admissions in the most specialized group...

..."The findings suggest that more specialized hospitals have better outcomes even after we account for the type of patients each hospital cares for and the number of hip and knee replacement surgeries that each hospital performs," Tyson Hagen, MD, the lead author of the study, stated in the release...
