I had some that helped up to 4 years! But the previous ones didn’t even come close . First one was 3 weeks 2 nd one was 9 months the 3rd one 18 months finally the 4 th one 4 years! The bad part I turn my meniscus I had surgery on that but they didn’t connect the acl ligament. The surgeon claimed I didn’t need it ! 3 years later half of my knee joint was gone ! They did an ingestion and it didn’t do anything. Had a partial knee replacement. The best that knee has been in a really long time ! My surgeon prescribed pensaid it was over a month before I had surgery for the replacement. Pensaid did wonders after a week . If your dr ever prescribes it ask or download a co pay card ! It’s very expensive but it take’s very little to rub on . My surgeon said if it doesn’t help any within a week it won’t ever help ! Good luck and hopefully things will turn around for you.
Pensaid is another word for generic Diclofenac Sodium, usually 1 %. It is an OTC in Canada and the generic is the equivalent of the brand name because the topical is manufactured in India. It offers effective but temporary relief. Problem is that it offers no permanent solution. I suggest looking at the many phase three trials for actual patella replacement. Your co-payment should be $5.00 for the generic. As a topical, the effect is temporary and does not heal but offers tremendous pain relief. One issue is that it may cause itching or even hives as a side effect.
