PRP THERAPY:

• PRP is plasma with many more platelets than what is typically found in blood. The concentration of platelets — and, thereby, the concentration of growth factors — can be 5 to 10 times greater (or richer) than usual. To develop a PRP preparation, blood must first be drawn from a patient. The platelets are separated from other blood cells and their concentration is increased by spinning the blood down during a process called centrifugation. These platelets are then injected into the injured site. To speed healing, the injury site is treated with the PRP preparation. 
• PRP can be carefully injected into the injured area. For example, in Achilles tendinitis, a condition commonly seen in runners and tennis players,  A mixture of PRP and local anesthetic can be injected directly into the inflamed tissue. Afterward, the pain in the area of injection may actually increase for the first week or two, and it may be several weeks before the patient feels a beneficial effect.

HYALURONIDASE INJECTIONS:
The injection technique for administering hyaluronic acid in the knee is called intra-articular injection. The term intra-articular injection refers to an injection given directly into the joint capsule.

The injection procedure takes a few minutes and usually does not involve any prior preparation. It is however advisable to discuss the medical history and current medications with the doctor prior to this treatment.

During a hyaluronic acid injection (viscosupplementation), a small amount of hyaluronic acid is injected directly into the knee joint capsule.

The goals of treating knee osteoarthritis with hyaluronic acid injections are to:

• Reduce pain
• Improve joint movement by increasing joint lubrication and reducing joint friction and inflammation
• Slow osteoarthritis progression
