Knee pain – cartilage damage – arthrosis

Hyaluronic acid – an advance in the treatment of arthrosis

Treatment with hyaluronic acid

Natural hyaluronic acid is the main component of joint fluid (synovium). It has a lubricating and shock-absorbing effect during all movements and supplies the joint cartilage with nutrients. As arthrosis progresses, the joint fluid becomes "thinner" and the concentration of hyaluronic acid in the joint fluid dwindles.

Since the start of the 1990s, hyaluronic acid produced using biotechnology has been used to treat arthritic joints. It is injected directly into the affected joint and supplements the joint fluid that has been modified by disease. This leads to improved "gliding" of the joint and better "buffering" of shocks during exertion (visco-elastic protection). The body's own production of hyaluronic acid is also stimulated and the release of cartilage-destroying enzymes is inhibited. This provides the joint with better and longer protection and can help slow down the progression of the arthrosis.

Hyaluronic acid preparations are made by a variety of manufacturers. The Praxisklinik München West prescribes Recosyn®, a preparation manufactured synthetically by Recordati.
Information about the manufacturer:
Recosyn®. The advantage in arthrosis treatment.
Recosyn® (active ingredient sodium hyaluronate) is indicated for pain and restricted mobility following degenerative or traumatic changes to the synovial joint area.


  • Reduces joint pain
  • Improves mobility

Medical background and mechanism of action

Hyaluronic acid is a natural substance that fulfils key physiological roles in many of the body's organs. Hyaluronic acid promotes the gliding action of the joints. In arthritic joints, this joint lubricant becomes "contaminated and depleted". The hyaluronic acid injected into the joint provides new "lubrication" for the joint. An improvement in the quality of the joint lubricant can be achieved through the intra-articular administration of high-purity, stabilised sodium hyaluronate (optimised visco-elastic properties). The lubricant and shock-absorbing effect of this product alleviates pain and improves the joint's mobility. This effect can last up to 12 months following

  • 3–5 injections of Recosyn®
  • 3 injections of Recosyn® forte

Recosyn®: a summary

Recosyn® is administered into the joint at weekly intervals. Depending on the size of the joint, up to 2 ml may be used intra-articularly. The simultaneous treatment of multiple joints and repeated treatment cycles are possible. After treatment, you should avoid putting heavy strain on the joint for 48 hours and also cool your joint with ice if necessary.
