![]() The conclusion of this study was that intra-articular injections of PRP showed a reduction of pain and recover function of the knee joint in patients affected by severe chondropathies of the knee. 8 published similar results in their study of 46 patients. Statistically significant objective and subjective improvements were noted at the end of treatment and at 6- and 12-month follow-up compared with pretreatment. In 2009, Kon and coworkers 7 injected PRP into 115 arthritic knees 3 times at 21-day intervals. Their findings demonstrated significant resolution of pain and restoration of function compared with baseline for up to 1 year after treatment in a majority of patients. Sampson and colleagues 6 injected osteoarthritic knees with PRP 3 separate times at 4-week intervals. See this link for a much more comprehensive list of published articles: Number of injections required, spacing between injections given in series, rehabilitation protocol during and after a series, etc) however, PRP is being used with regularity at the highest levels of sport and in the most highly compensated athletes in the world today. Moreover, a standard treatment regimen does not yet exist (i.e. Still, much of that information is undeniably compelling.įor this reason, most insurance companies will not support (read: pay for or “cover”) PRP treatment. However, an abundance of level 1 data to support the efficacy of PRP therapy is still lacking.Ĭurrently, much of what is guiding the use of PRP in orthopedic medicine is cohort data, conclusions drawn from case studies, and theory generated by in vitro and animal studies. Laboratory research and clinical studies have investigated its merit in both soft tissue conditions and bone healing. Studies are being published regularly describing the appropriate use and effectiveness of this treatment.Ī healthy amount of evidence suggests that PRP therapy offers great promise in musculoskeletal medicine. Studies have shown that PRP may be effective in treating many conditions such as mild-moderate joint arthritis and tendon and ligament injuries. Depending on the problem, multiple treatments may be required. The patient may experience between 2-5 days of soreness after the treatment and use of anti-inflammatory medications is not advised during treatment. Once the platelet portion of the blood is concentrated and separated, it is injected under ultrasound guidance to the problem area. The blood is drawn the same day of treatment and approximately 45 minutes is required for the visit. This procedure is done in the office setting with local anesthesia. When activated at a site of injury in the body, platelets release healing proteins called growth factors and attract cells that contribute to regrowth (stem cells). ![]() Platelets are responsible for blood clotting and healing. ![]() Blood is composed of red blood cells, white blood cells, plasma, and platelets.
