Abstract
Conservative management of osteoarthritis is boring, boring, boring! After all, we are surgeons. We operate, we cut! We all know that to retain respectability we have to go through the motions of ‘conservative management’, just so that we don't appear too anxious to apply a ‘real’ solution to the problem.
However, the statistics are overwhelming. An estimated 43 million Americans have ‘arthritis’, but only 400,000 are coming forward each year for TKR. That means that in one way or another 42,600,000 are being treated conservatively. Most of those are self treating by self medication, use of external support, but mostly by decreasing their activities to a level where they can tolerate symptoms. They come to us when these measures stop working.
We know what to do. 1. Weight loss – patients don't do it, 2. Physical therapy – very limited effectiveness 3. NSAIDS – patients have already tried OTC NSAIDS and have heard scary stories about therapeutic NSAIDS, 4. Hyaluronans – expensive, labour intensive, modest effectiveness, 5. Glucosamine/Chondroitin – might work, won't hurt, mixed evidence, 6. SAM-e, MSM – limited evidence – who knows?
What's on the horizon? Could OA of the knee go the way of RA, i.e. dramatically disappear from the population seeking TKR? It could happen. Electrical stimulation – it does good things for chondrocytes, circulation, suppresses destructive enzymes and in controlled studies reduces symptoms and improves function, deferring TKR. Cell therapy – possibly an effective solution to early cartilage lesions in the knee.
