Can collagen injections be used interchangeably with hyaluronic acid to treat knee pain? What's the difference? Will I buy them in pharmacies?

Collagen injections can be an alternative to hyaluronic acid in supporting the proper functioning of joints. Your doctor may suggest the simultaneous or replacement use of collagen and hyaluronic acid injections. Collagen replenishes collagen deficiencies at the injection site, supports the processes of reconstruction and protection of tissues against further damage. The administration of collagen to individual areas increases the range of motion of this part of the body (e.g. knees, in the case of collagen injection into the knee), facilitates muscle stretching and maintains their proper mass and reduces pain in the injected area.

In addition, it stimulates joint structures to spontaneous production of protective factors, e.g. chondroitin, proteoglycans and endogenous hyaluronic acid, thus additionally preventing the destruction of articular cartilage.

Injections can be purchased in pharmacies without a prescription.
