Knee replacement or prolotherapy -- when do you choose one over the other?

Knee: Depends on cause. Best to consult orthopedic specialist.

Consult orthopaedics: Prolotherapy is considered in the category of "complementary and alternative medicine"- with little scientific evidence to support its use. If your knee arthritis is severe and your pain has failed to respond to appropriate and thorough non-operative care, then knee replacement surgery can be considered. Talk to your orthopaedic surgeon about all your options for treatment.
