PRP Injections for Knee Osteoarthritis: What Patients Need to Know

Platelet-rich plasma (PRP) therapy is a type of regenerative medicine that uses your own plasma to target damaged tissues. Because it draws from your body’s natural healing components, the treatment may support recovery in specific areas. Understanding what to expect during and after PRP injections helps patients prepare for the process. Here are some of the factors of PRP injections for knee osteoarthritis and what patients need to know: 

PRP Injections 

Your body naturally contains the components needed for tissue repair, and PRP injections work to support this process. Plasma circulates red and white blood cells throughout the body, while platelets carry growth factors that can promote cell regeneration. By harnessing these natural elements, PRP therapy targets areas of tissue damage.

When injected into an affected site, PRP may help reduce discomfort and support the repair of injured tissues. The therapy aims to complement the body’s own healing mechanisms rather than replace them. Patients often receive guidance from medical professionals to determine the appropriate treatment approach for their specific needs.

Conditions Treated 

PRP therapy may be used to address a variety of conditions, particularly those involving chronic pain, joint degeneration, or soft tissue injuries. It targets areas where tissue repair and regeneration could support improved function, mobility, and overall joint comfort, while complementing other rehabilitation approaches. Specific conditions that may be treated with PRP include:

• Knee arthritis
• Meniscus tear
• Ligament injuries
• Disc degeneration
• Labral tears of the shoulder or hip
• Rotator cuff tears
• Tennis elbow

Patients interested in PRP therapy should discuss their medical history, current medications, and previous treatments with a qualified healthcare professional. This conversation helps determine whether PRP injections are suitable, how many sessions might be needed, and what outcomes to expect over time.

Injection Process

A medical professional begins by drawing blood from your arm, which is then placed in a centrifuge to separate the platelet-rich plasma from other components. Once isolated, the PRP is injected into the injured area. Over time, the platelets break down and release growth factors, which may support the body’s natural healing processes and tissue repair.

Afterward Treatment

PRP treatments usually take around 30 minutes per session, and because the procedure is minimally invasive, most patients can resume normal activities shortly afterward. Many individuals undergo two to four sessions, depending on their condition, and initial effects often appear within two to three weeks. More significant improvements may develop over three to six months as the body responds to the therapy.

It is common to experience minor soreness at the injection site following treatment, and immediate pain relief is not typical. Patients are encouraged to monitor their response and follow any post-treatment instructions provided by their healthcare professional. Understanding the gradual nature of recovery can help set realistic expectations for results.

PRP therapy can be combined with other pain management treatments, supporting recovery while helping restore function to injured areas. Some individuals rely on anti-inflammatory medications, but they may explore PRP as an alternative approach. By consulting a qualified medical professional who understands your condition, patients can weigh potential benefits and risks. Schedule a consultation to discuss whether PRP injections are appropriate for your situation.
