On-Q pain pump and other models may cause cartilage damage: Study
Did use of an On-Q pain pump lead to "chondrolysis" condition? Consider discussing your situation with our lawyers.
In a study published in the Journal of Shoulder Elbow Surgery, 2009 Sep-Oct; titled "Severe chondrolysis after shoulder arthroscopy: a case series," by Bailie DS, Ellenbecker TS of the Orthopedic Clinic Association, the authors discuss a special medical procedure involving the insertion of pain pumps directly in the shoulder joint. Some of the pain pump models on the market available for use in this procedure include the On-Q pain pump, Stryker IFlow and Medtronic.
The hypothesis section of the pain pump study pointed out that chondrolysis--the very painful and permanent degeneration of shoulder cartilage--has been observed after shoulder arthroscopy and results in severe glenohumeral complications.
The authors examine 23 cases in their medical practice of post-arthroscopic glenohumeral chondrolysis, occurring between 2005-2006, that were reported following a variety of arthroscopic shoulder procedures.

Pain pumps are used to manage post-operative shoulder surgery pain. They should be placed in the muscle or outside the shoulder joint. However, with little or no study regarding safety, the surgical approach of inserting pain pumps directly in the shoulder joint has been extensive over the last 7 years. This treatment is now linked to chondrolysis, also known as "PAGCL," an excruciating condition for which there is no cure.
“There does not appear to have been any published safety testing upon which manufacturers were relying to market pain pumps for intra-articular use,” said Paul Pennock, director of the Weitz & Luxenberg defective drug and medical device unit.
The researchers concluded that chondrolysis is a devastating complication of arthroscopic shoulder surgery that can result in long-term disabling consequences. In closing, they warn, "we strongly advise against the use of large doses of intra-articular placement of local anesthetics," referring to a particular surgical use of pain pumps such as On-Q.
