Localized Herx: knee

A patient presented to me with an acute swollen knee. She had been healthy until another physician prescribed a course of Cipro for a urinary tract infection.
She had typical mono-articular arthritis: arthritis of a single joint. The knee was swollen, red an hot with a large effusion. The patient tested positive for Lyme disease and was successfully treated.

This- I think may demonstrate the concept which I alluded to in the response to my last entry. First of all many ostensibly healthy persons are infected with sub-clinical Lyme. Something- many things, can set off the disease. Second, Herxes can be very localized, presenting in a specific area.

Many thinking in this case was that the Lyme organisms were present in the synovial tissues of this patent's knees. Cipro, a quinolone, was able to have exceptional penetration in to these tissues. As a result, this localized Herx occurred in the patient's knee. Post-quinolone treatment relied on less potent antibiotic, which have less penetration into synovial tissues. These tissues are minimally penetrated by most other antibiotics.Therapy with Amoxil and Biaxin, over time, was successful:swelling and arthritis gradually improved.

It is pure conjecture. I simply ask the question: could tendon rupture seen with quinolones represent a similar reaction?
